Yah, it's up to 40 watts now! Not quite room
temperature. But so appreciate the hand-holding!
My bad- I messed up my form by not saving one of the
modules when it asked me (several times), and I had to
create the form over- forgetting the on_current:
Me.ImagePicture.Picture = Me.ImagePath

Much better now- I have picture!! (it was so exciting!)
but not quite right.

That very code:
Me.ImagePicture.Picture = Me.ImagePath
is giving me grief- run-time error '94' invalid use of
null.

I took the "." vs. "!" advice (nice), but didn't need to
use Me.txtPath=strFilename. But I did check it out and
liked the idea so I created a field to show the picture
path- handy when we need to update the picture. Anyway,
Record1 has a path and a picture. When I navigate to
Record2, I get the error, see that there is no path, yet
it has Record1's picture. Strange. I click "end" rather
than "debug". Go on to Record 3 (no error getting there
because Record3 has a path and a picture). Record4 (error-
no path/picture), click "end" and all the rest of my
records have no path but Record3's picture (the last
record with a picture). So, code is not happy when there
is no picture attached to the Record, makes up it's own
picture, and yells at me before I even have a chance to
attach the picture. What did I do wrong now? I'm feeling
it. Thanks, Mich

Or posts have crossed each other. If you look at my

previous (to this post)
post, you need to change the line where it checks to see

if strFilename =
"Cancelled" to just checking if strFilename= "". The new

functions don't
return "Cancelled" if you cancel the browser. Because

it's checking for
"Cancelled" and not seeing it, it continues the code and

tries to store an
empty string in your table.

It looks like the little lightbulb over your head is

getting brighter and
brighter!

OK, now's the time to think not just paste!
Here's what I have:

Private Sub ImagePicture_Click()
Dim strFilename As String, strFind As String
Dim lngID As Long

'strFilename = GetTheFilename("Browse to the file")
strFilename = GetOpenFile(, "Browse for a file")

If strFilename = "Cancelled" Then
Exit Sub
End If

'Me!FilePath = strFilename
Me!ImagePath = strFilename
'lngID = Me!ItemID
lngID = Me!AnimalsID
'strFind = "[ItemID]=" & lngID
strFind = "[AnimalsID]=" & lngID

Echo False
Me.Requery
Me.Recordset.FindFirst strFind
Echo True

End Sub

I was getting an error message that (I think) strFind

was
zero length. But now I'm getting nothing- no error
message, no picture. Wait here's the error:
run-time error '3315' Field 'Animals.ImagePath' cannot

be
a zero-length string.

I did make sure that ImagePath is in the record source

and
that the text field is 50 characters to handle the path.

I still must be doing something wrong. So close!

Thanks,

Michelle,
Long ago, I was given a bunch of code which was written

back in the Access97
days, which uses calls to the Windows components to open

the file dialog.
I'm pasting it here, but be prepared for a long bunch of

code! Just copy
what's between the ***start copy*** and ***end copy***.

Paste it into a new
module; mine was called modFileRequestor...
For your image_click event use this code instead of what

I had befo
GetOpenFile(, "Browse for a file")

As for confusing names like table "Animals" and

form "Animals", I alway put
a three-character identifier on all my objects--

tblAnimals or frmAnimals or
qryAnimals, etc. Just for clarity, you might want to

rename your field in
the table to "ImagePath", and maybe your image control

on
the form to
"imgPicture". You shouldn't have to change the image

property from
"embedded"; it won't matter since it's not being saved

with the form. If
you still get the error about "can't find the field..."

double-check your
form's recordsource to make sure the new path field is

in
there.

Mark, Thanks! I appreciate the detail steps. And

it's
embarrassing when I can't follow them!
I'm getting an error message: run-time error '2465'
Microsoft Access can't find the field 'FilePath'

referred
to in your expresion. I can't get from design view to
form view because of it.

On my Animals table I added FilePath as a text field.

And
in my Animals form (confusing names, I know) I added

the
picture (which I had to put a box around so I could

find
it!), deleted the actual picture/path and called the
field: ImageControl. Should the picture type

be "linked"
rather than "embedded"?

Private Sub Form_Current()
Me.ImageControl.Picture = Me!FilePath
End Sub

I don't understand why this didn't work.

So I commented it out, and then I get a compile error:
expected variable or procedure, not module
and remembered to name the module: GetTheFilenamemdl
rather than GetTheFilename. See! I can be taught.

Now, it's not liking
Dim dlgFilePick As FileDialog
I've never seen FileDialog. This must be what you
mentioned as tweaking the file browser function as I'm
using Access 2000. So I took a peek in the library

and
I
have these checked (and in this order):
VB for applications
Microsoft Access 9.0 object library
OLE Automation
Microsoft DAO 3.6 object library
Microsoft ActiveX Sata Objects 2.1 library

Am I salvagable? Thanks for your help, Michelle

-----Original Message-----
Hi Michelle,

For testing, you can certainly just type in the full

path
(don't need
quotes) to the image (don't forget the file's

extension
like Dog1.jpg). On
the form, add an image and select any old image from

the
wizard. Once the
control is on the form, you can go to properties and
erase the file path in
the "Picture" property. Now you have a blank

(unbound)
image control.

In my test form I whipped up to refresh my memory, I

just
used the default
name of the control, which happened to be "Image7".
Since the file path is
saved with the record, you'll always get the correct
image for the record
being displayed.

When your user clicks on the image (or blank image box

if
there's no image
assigned yet), the full filename with path is stored

in
the FilePath field
for that record and the form's recordset is requeried

to
update the image.
The ImageControl's OnClick event:
'*********code start************
Private Sub ImageControl_Click()
Dim strFilename As String, strFind As String
Dim lngID As Long

strFilename = GetTheFilename("Browse to the file")
If strFilename = "Cancelled" Then
Exit Sub
End If
Me!FilePath = strFilename
lngID = Me!ItemID
strFind = "[ItemID]=" & lngID
Echo False
Me.Requery
Me.Recordset.FindFirst strFind
Echo True

'********code end************

In a regular module (for the file requestor),
'********code start********
Function GetTheFilename(strTitle As String) As String
Dim strFilename As String
Dim dlgFilePick As FileDialog
Dim vrtSelectedItem As Variant

On Error GoTo Err_GetFilename
Set dlgFilePick = Application.FileDialog
(msoFileDialogFilePicker)
With dlgFilePick
.Title = strTitle
'Let user select only one file
.AllowMultiSelect = False
If .Show = -1 Then
'The user pressed the action button.
GetTheFilename = .SelectedItems(1)

Else
'The user pressed Cancel.
GetTheFilename = "Cancelled"
End If
End With

Exit_GetFilename:
Set dlgFilePick = Nothing
Exit Function
Err_GetFilename:
MsgBox "Error " & Err.Number & ": " &
Err.Description, ,
"GetTheFilename"
Resume Exit_GetFilename
End Function
'********code end************

I'm using Access2003, so the file browser function

might
need tweaking for
older versions.
Hope this helps!

I like the sound of that! I only have 5 pictures so

far
and they are slow to load.

I want to try it! I created a new text field

(FilePath)
in
table Animals. My file path for the 1st picture is
C:\My Documents\My Pictures\Dog1
so I enter the above path in the Animals table,

FilePath
field for Dog1's record. Correct? Do I need the

file
path in quotes?

How do I create an unbound image control on the

form? I
see the tool bar offers "image", "unbound object

frame"
and a "bound object frame"- all of which want me to
select
the image now. What am I missing to get an unbound
image
control?

I'm confused about: Me.Image7.Picture = Me!FilePath
Does Image7 mean something? Is that the name of

your
image in the record? If so, how does the record

know
which picture to show for which record- must be by

the
file path name...

You said "When you click the image control, the user
browses to the picture they want to assign to the
current
record."- that sounds cool! So I set up the unbound
image
control once in the table and then the user gets to
choose
the picture, so that the user is never in the table-
correct? That would be excellent!

Thanks for the guidance!
Michelle

-----Original Message-----
I used to have an ID badge database that stored the
digital pictures in an
OLE field. There was an OLE control on the form

which,
when clicked, would
let you browse to select the file. With only 100 or

so
employee records, the
database bloated to over 200Mb. I have since

modified
the database to get
rid of the OLE field and control. I'm now storing

the
path to the picture
in a text field called FilePath and the database is
under
200Kb. I've got
an unbound image control on the form, and in the

form's
OnCurrent event I
have:

Me.Image7.Picture = Me!FilePath

which will change the picture to match the picture

you
assigned to the
current record. When you click the image control,

the
user browses to the
picture they want to assign to the current record.

It
works with both JPG
and BMP files.

Sorry about that!
I have form that I want to show a digital camera
picture.
I have the table field set up as an OLE Object.

Can I load the picture from the form, or do I need

to
go
to the table, find the correct record for the

field,
select Insert object and the browse to the correct
digital
camera picture? There's got to be an easier way

for
end-
users!

I see that bitmap is an option, but my digital

camera
pictures are jpg. How do I upload these?

Thanks,
Mich

All you need to do is check to see if there's a path stored, and if not just
set the Picture property to nothing:

If Me.ImagePath = "" Then
Me.ImagePicture.Picture = ""
Else
Me.ImagePicture.Picture = Me.ImagePath
End If

Mark, Thanks! I appreciate the detail steps. And

it's
embarrassing when I can't follow them!
I'm getting an error message: run-time error '2465'
Microsoft Access can't find the field 'FilePath'
referred
to in your expresion. I can't get from design view to
form view because of it.

On my Animals table I added FilePath as a text field.
And
in my Animals form (confusing names, I know) I added

the
picture (which I had to put a box around so I could

find
it!), deleted the actual picture/path and called the
field: ImageControl. Should the picture type
be "linked"
rather than "embedded"?

Private Sub Form_Current()
Me.ImageControl.Picture = Me!FilePath
End Sub

I don't understand why this didn't work.

So I commented it out, and then I get a compile error:
expected variable or procedure, not module
and remembered to name the module: GetTheFilenamemdl
rather than GetTheFilename. See! I can be taught.

Now, it's not liking
Dim dlgFilePick As FileDialog
I've never seen FileDialog. This must be what you
mentioned as tweaking the file browser function as I'm
using Access 2000. So I took a peek in the library

and
I
have these checked (and in this order):
VB for applications
Microsoft Access 9.0 object library
OLE Automation
Microsoft DAO 3.6 object library
Microsoft ActiveX Sata Objects 2.1 library

Am I salvagable? Thanks for your help, Michelle

Hi Michelle,

For testing, you can certainly just type in the full
path
(don't need
quotes) to the image (don't forget the file's

extension
like Dog1.jpg). On
the form, add an image and select any old image from

the
wizard. Once the
control is on the form, you can go to properties and
erase the file path in
the "Picture" property. Now you have a blank

(unbound)
image control.

In my test form I whipped up to refresh my memory, I
just
used the default
name of the control, which happened to be "Image7".
Since the file path is
saved with the record, you'll always get the correct
image for the record
being displayed.

When your user clicks on the image (or blank image box
if
there's no image
assigned yet), the full filename with path is stored

in
the FilePath field
for that record and the form's recordset is requeried

to
update the image.
The ImageControl's OnClick event:
'*********code start************
Private Sub ImageControl_Click()
Dim strFilename As String, strFind As String
Dim lngID As Long

strFilename = GetTheFilename("Browse to the file")
If strFilename = "Cancelled" Then
Exit Sub
End If
Me!FilePath = strFilename
lngID = Me!ItemID
strFind = "[ItemID]=" & lngID
Echo False
Me.Requery
Me.Recordset.FindFirst strFind
Echo True

'********code end************

In a regular module (for the file requestor),
'********code start********
Function GetTheFilename(strTitle As String) As String
Dim strFilename As String
Dim dlgFilePick As FileDialog
Dim vrtSelectedItem As Variant

On Error GoTo Err_GetFilename
Set dlgFilePick = Application.FileDialog
(msoFileDialogFilePicker)
With dlgFilePick
.Title = strTitle
'Let user select only one file
.AllowMultiSelect = False
If .Show = -1 Then
'The user pressed the action button.
GetTheFilename = .SelectedItems(1)

Else
'The user pressed Cancel.
GetTheFilename = "Cancelled"
End If
End With

Exit_GetFilename:
Set dlgFilePick = Nothing
Exit Function
Err_GetFilename:
MsgBox "Error " & Err.Number & ": " &
Err.Description, ,
"GetTheFilename"
Resume Exit_GetFilename
End Function
'********code end************

I'm using Access2003, so the file browser function

might
need tweaking for
older versions.
Hope this helps!

I like the sound of that! I only have 5 pictures so
far
and they are slow to load.

I want to try it! I created a new text field
(FilePath)
in
table Animals. My file path for the 1st picture is
C:\My Documents\My Pictures\Dog1
so I enter the above path in the Animals table,
FilePath
field for Dog1's record. Correct? Do I need the

file
path in quotes?

How do I create an unbound image control on the
form? I
see the tool bar offers "image", "unbound object
frame"
and a "bound object frame"- all of which want me to
select
the image now. What am I missing to get an unbound
image
control?

I'm confused about: Me.Image7.Picture = Me!FilePath
Does Image7 mean something? Is that the name of

your
image in the record? If so, how does the record

know
which picture to show for which record- must be by

the
file path name...

You said "When you click the image control, the user
browses to the picture they want to assign to the
current
record."- that sounds cool! So I set up the unbound
image
control once in the table and then the user gets to
choose
the picture, so that the user is never in the table-
correct? That would be excellent!

Thanks for the guidance!
Michelle

I used to have an ID badge database that stored the
digital pictures in an
OLE field. There was an OLE control on the form
which,
when clicked, would
let you browse to select the file. With only 100 or

so
employee records, the
database bloated to over 200Mb. I have since

modified
the database to get
rid of the OLE field and control. I'm now storing

the
path to the picture
in a text field called FilePath and the database is
under
200Kb. I've got
an unbound image control on the form, and in the
form's
OnCurrent event I
have:

Me.Image7.Picture = Me!FilePath

which will change the picture to match the picture

you
assigned to the
current record. When you click the image control,

the
user browses to the
picture they want to assign to the current record.

It
works with both JPG
and BMP files.

Sorry about that!
I have form that I want to show a digital camera
picture.
I have the table field set up as an OLE Object.

Can I load the picture from the form, or do I need
to
go
to the table, find the correct record for the

field,
select Insert object and the browse to the correct
digital
camera picture? There's got to be an easier way

for
end-
users!

I see that bitmap is an option, but my digital
camera
pictures are jpg. How do I upload these?

Thanks,
Mich

Oops, my bad here...
Instead of
If Me.ImagePath = "" Then
It might need to be
If Not IsNull(Me.ImagePath) Then

I think it depends of whether you're checking the field contents or the
control contents.

"Mark" Pseudo Access Expert wrote in message
...
All you need to do is check to see if there's a path stored, and if not
just set the Picture property to nothing:

If Me.ImagePath = "" Then
Me.ImagePicture.Picture = ""
Else
Me.ImagePicture.Picture = Me.ImagePath
End If

Yah, it's up to 40 watts now! Not quite room
temperature. But so appreciate the hand-holding!
My bad- I messed up my form by not saving one of the
modules when it asked me (several times), and I had to
create the form over- forgetting the on_current:
Me.ImagePicture.Picture = Me.ImagePath

Much better now- I have picture!! (it was so exciting!)
but not quite right.

That very code:
Me.ImagePicture.Picture = Me.ImagePath
is giving me grief- run-time error '94' invalid use of
null.

I took the "." vs. "!" advice (nice), but didn't need to
use Me.txtPath=strFilename. But I did check it out and
liked the idea so I created a field to show the picture
path- handy when we need to update the picture. Anyway,
Record1 has a path and a picture. When I navigate to
Record2, I get the error, see that there is no path, yet
it has Record1's picture. Strange. I click "end" rather
than "debug". Go on to Record 3 (no error getting there
because Record3 has a path and a picture). Record4 (error-
no path/picture), click "end" and all the rest of my
records have no path but Record3's picture (the last
record with a picture). So, code is not happy when there
is no picture attached to the Record, makes up it's own
picture, and yells at me before I even have a chance to
attach the picture. What did I do wrong now? I'm feeling
it. Thanks, Mich

Or posts have crossed each other. If you look at my

previous (to this post)
post, you need to change the line where it checks to see

if strFilename =
"Cancelled" to just checking if strFilename= "". The new

functions don't
return "Cancelled" if you cancel the browser. Because

it's checking for
"Cancelled" and not seeing it, it continues the code and

tries to store an
empty string in your table.

It looks like the little lightbulb over your head is

getting brighter and
brighter!

OK, now's the time to think not just paste!
Here's what I have:

Private Sub ImagePicture_Click()
Dim strFilename As String, strFind As String
Dim lngID As Long

'strFilename = GetTheFilename("Browse to the file")
strFilename = GetOpenFile(, "Browse for a file")

If strFilename = "Cancelled" Then
Exit Sub
End If

'Me!FilePath = strFilename
Me!ImagePath = strFilename
'lngID = Me!ItemID
lngID = Me!AnimalsID
'strFind = "[ItemID]=" & lngID
strFind = "[AnimalsID]=" & lngID

Echo False
Me.Requery
Me.Recordset.FindFirst strFind
Echo True

End Sub

I was getting an error message that (I think) strFind

was
zero length. But now I'm getting nothing- no error
message, no picture. Wait here's the error:
run-time error '3315' Field 'Animals.ImagePath' cannot

be
a zero-length string.

I did make sure that ImagePath is in the record source

and
that the text field is 50 characters to handle the path.

I still must be doing something wrong. So close!

Thanks,
Michelle

Michelle,
Long ago, I was given a bunch of code which was written
back in the Access97
days, which uses calls to the Windows components to open
the file dialog.
I'm pasting it here, but be prepared for a long bunch of
code! Just copy
what's between the ***start copy*** and ***end copy***.
Paste it into a new
module; mine was called modFileRequestor...
For your image_click event use this code instead of what
I had befo
GetOpenFile(, "Browse for a file")

As for confusing names like table "Animals" and
form "Animals", I alway put
a three-character identifier on all my objects--
tblAnimals or frmAnimals or
qryAnimals, etc. Just for clarity, you might want to
rename your field in
the table to "ImagePath", and maybe your image control

on
the form to
"imgPicture". You shouldn't have to change the image
property from
"embedded"; it won't matter since it's not being saved
with the form. If
you still get the error about "can't find the field..."
double-check your
form's recordsource to make sure the new path field is

in
there.

Hi Michelle,

For testing, you can certainly just type in the full
path
(don't need
quotes) to the image (don't forget the file's

extension
like Dog1.jpg). On
the form, add an image and select any old image from

the
wizard. Once the
control is on the form, you can go to properties and
erase the file path in
the "Picture" property. Now you have a blank

(unbound)
image control.

In my test form I whipped up to refresh my memory, I
just
used the default
name of the control, which happened to be "Image7".
Since the file path is
saved with the record, you'll always get the correct
image for the record
being displayed.

When your user clicks on the image (or blank image box
if
there's no image
assigned yet), the full filename with path is stored

in
the FilePath field
for that record and the form's recordset is requeried

to
update the image.
The ImageControl's OnClick event:
'*********code start************
Private Sub ImageControl_Click()
Dim strFilename As String, strFind As String
Dim lngID As Long

strFilename = GetTheFilename("Browse to the file")
If strFilename = "Cancelled" Then
Exit Sub
End If
Me!FilePath = strFilename
lngID = Me!ItemID
strFind = "[ItemID]=" & lngID
Echo False
Me.Requery
Me.Recordset.FindFirst strFind

'********code end************

In a regular module (for the file requestor),

Exit Function

I'm using Access2003, so the file browser function

might
need tweaking for
older versions.
Hope this helps!

I like the sound of that! I only have 5 pictures so
far
and they are slow to load.

I want to try it! I created a new text field
(FilePath)
in
table Animals. My file path for the 1st picture is
C:\My Documents\My Pictures\Dog1
so I enter the above path in the Animals table,
FilePath
field for Dog1's record. Correct? Do I need the

file
path in quotes?

How do I create an unbound image control on the
form? I
see the tool bar offers "image", "unbound object
frame"
and a "bound object frame"- all of which want me to
select
the image now. What am I missing to get an unbound
image
control?

I'm confused about: Me.Image7.Picture = Me!FilePath
Does Image7 mean something? Is that the name of

your
image in the record? If so, how does the record

know
which picture to show for which record- must be by

the
file path name...

You said "When you click the image control, the user
browses to the picture they want to assign to the
current
record."- that sounds cool! So I set up the unbound
image
control once in the table and then the user gets to
choose
the picture, so that the user is never in the table-
correct? That would be excellent!

Thanks for the guidance!
Michelle

-----Original Message-----
I used to have an ID badge database that stored the
digital pictures in an
OLE field. There was an OLE control on the form
which,
when clicked, would
let you browse to select the file. With only 100 or

so
employee records, the
database bloated to over 200Mb. I have since

modified
the database to get
rid of the OLE field and control. I'm now storing

the
path to the picture
in a text field called FilePath and the database is
under
200Kb. I've got
an unbound image control on the form, and in the
form's
OnCurrent event I
have:

Me.Image7.Picture = Me!FilePath

which will change the picture to match the picture

you
assigned to the
current record. When you click the image control,

the
user browses to the
picture they want to assign to the current record.

It
works with both JPG
and BMP files.

Sorry about that!
I have form that I want to show a digital camera
picture.
I have the table field set up as an OLE Object.

Can I load the picture from the form, or do I need
to
go
to the table, find the correct record for the

field,
select Insert object and the browse to the correct
digital
camera picture? There's got to be an easier way

for
end-
users!

I see that bitmap is an option, but my digital
camera
pictures are jpg. How do I upload these?

Thanks,

Hmm. I now have:

Private Sub Form_Current()
If Me.ImagePath = "" Then
Me.ImagePicture.Picture = ""
Else
Me.ImagePicture.Picture = Me.ImagePath
End If
End Sub

but it's still giving the same error. I'm on Record1
(path) and naviagte to Record2 (no real path), I get the
error and when I go to debug Me.ImagePicture.Picture =
Me.ImagePath is showing the path from Record1. I can't
tell if thinks it's on record1 or thinks record2 has
record1's path. In any case, it doesn't think it's null
when it is. Thanks, Mich

-----Original Message-----
All you need to do is check to see if there's a path

stored, and if not just
set the Picture property to nothing:

If Me.ImagePath = "" Then
Me.ImagePicture.Picture = ""
Else
Me.ImagePicture.Picture = Me.ImagePath
End If

Yah, it's up to 40 watts now! Not quite room
temperature. But so appreciate the hand-holding!
My bad- I messed up my form by not saving one of the
modules when it asked me (several times), and I had to
create the form over- forgetting the on_current:
Me.ImagePicture.Picture = Me.ImagePath

Much better now- I have picture!! (it was so exciting!)
but not quite right.

That very code:
Me.ImagePicture.Picture = Me.ImagePath
is giving me grief- run-time error '94' invalid use of
null.

I took the "." vs. "!" advice (nice), but didn't need to
use Me.txtPath=strFilename. But I did check it out and
liked the idea so I created a field to show the picture
path- handy when we need to update the picture. Anyway,
Record1 has a path and a picture. When I navigate to
Record2, I get the error, see that there is no path, yet
it has Record1's picture. Strange. I click "end" rather
than "debug". Go on to Record 3 (no error getting there
because Record3 has a path and a picture). Record4

(error-
no path/picture), click "end" and all the rest of my
records have no path but Record3's picture (the last
record with a picture). So, code is not happy when there
is no picture attached to the Record, makes up it's own
picture, and yells at me before I even have a chance to
attach the picture. What did I do wrong now? I'm

feeling
it. Thanks, Mich

Or posts have crossed each other. If you look at my

previous (to this post)
post, you need to change the line where it checks to see

if strFilename =
"Cancelled" to just checking if strFilename= "". The

new
functions don't
return "Cancelled" if you cancel the browser. Because

it's checking for
"Cancelled" and not seeing it, it continues the code and

tries to store an
empty string in your table.

It looks like the little lightbulb over your head is

getting brighter and
brighter!

OK, now's the time to think not just paste!
Here's what I have:

Private Sub ImagePicture_Click()
Dim strFilename As String, strFind As String
Dim lngID As Long

'strFilename = GetTheFilename("Browse to the file")
strFilename = GetOpenFile(, "Browse for a file")

If strFilename = "Cancelled" Then
Exit Sub
End If

'Me!FilePath = strFilename
Me!ImagePath = strFilename
'lngID = Me!ItemID
lngID = Me!AnimalsID
'strFind = "[ItemID]=" & lngID
strFind = "[AnimalsID]=" & lngID

Echo False
Me.Requery
Me.Recordset.FindFirst strFind
Echo True

End Sub

I was getting an error message that (I think) strFind

was
zero length. But now I'm getting nothing- no error
message, no picture. Wait here's the error:
run-time error '3315' Field 'Animals.ImagePath' cannot

be
a zero-length string.

I did make sure that ImagePath is in the record source

and
that the text field is 50 characters to handle the

path.

I still must be doing something wrong. So close!

Thanks,
Michelle

Michelle,
Long ago, I was given a bunch of code which was

written
back in the Access97
days, which uses calls to the Windows components to

open
the file dialog.
I'm pasting it here, but be prepared for a long bunch

of
code! Just copy
what's between the ***start copy*** and ***end

copy***.
Paste it into a new
module; mine was called modFileRequestor...
For your image_click event use this code instead of

what
I had befo
GetOpenFile(, "Browse for a file")

As for confusing names like table "Animals" and
form "Animals", I alway put
a three-character identifier on all my objects--
tblAnimals or frmAnimals or
qryAnimals, etc. Just for clarity, you might want to
rename your field in
the table to "ImagePath", and maybe your image control

on
the form to
"imgPicture". You shouldn't have to change the image
property from
"embedded"; it won't matter since it's not being saved
with the form. If
you still get the error about "can't find the

field..."
double-check your
form's recordsource to make sure the new path field is

in
there.

I want to try it! I created a new text field
(FilePath)
in
table Animals. My file path for the 1st picture

is
C:\My Documents\My Pictures\Dog1
so I enter the above path in the Animals table,
FilePath
field for Dog1's record. Correct? Do I need the

file
path in quotes?

How do I create an unbound image control on the
form? I
see the tool bar offers "image", "unbound object
frame"
and a "bound object frame"- all of which want me

to
select
the image now. What am I missing to get an

unbound
image
control?

I'm confused about: Me.Image7.Picture = Me!

FilePath
Does Image7 mean something? Is that the name of

your
image in the record? If so, how does the record

know
which picture to show for which record- must be by

the
file path name...

You said "When you click the image control, the

user
browses to the picture they want to assign to the
current
record."- that sounds cool! So I set up the

unbound
image
control once in the table and then the user gets

to
choose
the picture, so that the user is never in the

table-
correct? That would be excellent!

Thanks for the guidance!

I used to have an ID badge database that stored

the
digital pictures in an
OLE field. There was an OLE control on the form
which,
when clicked, would
let you browse to select the file. With only 100

or
so
employee records, the
database bloated to over 200Mb. I have since

modified
the database to get
rid of the OLE field and control. I'm now storing

the
path to the picture
in a text field called FilePath and the database

is
under
200Kb. I've got
an unbound image control on the form, and in the
form's
OnCurrent event I
have:

Me.Image7.Picture = Me!FilePath

which will change the picture to match the picture

you
assigned to the
current record. When you click the image control,

the
user browses to the
picture they want to assign to the current record.

It
works with both JPG
and BMP files.

Sorry about that!
I have form that I want to show a digital camera
picture.
I have the table field set up as an OLE Object.

Can I load the picture from the form, or do I

need
to
go
to the table, find the correct record for the

field,
select Insert object and the browse to the

correct
digital
camera picture? There's got to be an easier way

for
end-
users!

I see that bitmap is an option, but my digital
camera
pictures are jpg. How do I upload these?

Thanks,
Mich

Yeah, my brain is running out of steam. I think we need to check for null
instead of empty:

If IsNull(Me.ImagePath) Then
Me.ImagePicture.Picture = ""
Else
Me.ImagePicture.Picture = Me.ImagePath
End If

I always have to play around with the IsNull vs ="" to get certain things to
work right.

Hmm. I now have:

but it's still giving the same error. I'm on Record1

error and when I go to debug Me.ImagePicture.Picture =
Me.ImagePath is showing the path from Record1. I can't

All you need to do is check to see if there's a path

stored, and if not just
set the Picture property to nothing:

If Me.ImagePath = "" Then
Me.ImagePicture.Picture = ""
Else

My bad- I messed up my form by not saving one of the
modules when it asked me (several times), and I had to
create the form over- forgetting the on_current:
Me.ImagePicture.Picture = Me.ImagePath

Much better now- I have picture!! (it was so exciting!)
but not quite right.

That very code:
Me.ImagePicture.Picture = Me.ImagePath
is giving me grief- run-time error '94' invalid use of
null.

I took the "." vs. "!" advice (nice), but didn't need to
use Me.txtPath=strFilename. But I did check it out and
liked the idea so I created a field to show the picture
path- handy when we need to update the picture. Anyway,
Record1 has a path and a picture. When I navigate to
Record2, I get the error, see that there is no path, yet
it has Record1's picture. Strange. I click "end" rather
than "debug". Go on to Record 3 (no error getting there
because Record3 has a path and a picture). Record4

(error-
no path/picture), click "end" and all the rest of my
records have no path but Record3's picture (the last
record with a picture). So, code is not happy when there
is no picture attached to the Record, makes up it's own
picture, and yells at me before I even have a chance to
attach the picture. What did I do wrong now? I'm

feeling
it. Thanks, Mich

Or posts have crossed each other. If you look at my
previous (to this post)
post, you need to change the line where it checks to see
if strFilename =
"Cancelled" to just checking if strFilename= "". The

new
functions don't
return "Cancelled" if you cancel the browser. Because
it's checking for
"Cancelled" and not seeing it, it continues the code and
tries to store an
empty string in your table.

It looks like the little lightbulb over your head is
getting brighter and
brighter!

OK, now's the time to think not just paste!
Here's what I have:

Private Sub ImagePicture_Click()
Dim strFilename As String, strFind As String
Dim lngID As Long

'strFilename = GetTheFilename("Browse to the file")
strFilename = GetOpenFile(, "Browse for a file")

If strFilename = "Cancelled" Then
Exit Sub
End If

'Me!FilePath = strFilename
Me!ImagePath = strFilename
'lngID = Me!ItemID
lngID = Me!AnimalsID
'strFind = "[ItemID]=" & lngID
strFind = "[AnimalsID]=" & lngID

Echo False
Me.Requery
Me.Recordset.FindFirst strFind
Echo True

End Sub

I was getting an error message that (I think) strFind
was
zero length. But now I'm getting nothing- no error
message, no picture. Wait here's the error:
run-time error '3315' Field 'Animals.ImagePath' cannot
be
a zero-length string.

I did make sure that ImagePath is in the record source
and
that the text field is 50 characters to handle the

path.

I still must be doing something wrong. So close!

Michelle,
Long ago, I was given a bunch of code which was

written
back in the Access97
days, which uses calls to the Windows components to

open
the file dialog.
I'm pasting it here, but be prepared for a long bunch

of
code! Just copy
what's between the ***start copy*** and ***end

copy***.
Paste it into a new
module; mine was called modFileRequestor...
For your image_click event use this code instead of

what
I had befo
GetOpenFile(, "Browse for a file")

As for confusing names like table "Animals" and
form "Animals", I alway put
a three-character identifier on all my objects--
tblAnimals or frmAnimals or
qryAnimals, etc. Just for clarity, you might want to
rename your field in
the table to "ImagePath", and maybe your image control
on
the form to
"imgPicture". You shouldn't have to change the image
property from
"embedded"; it won't matter since it's not being saved
with the form. If
you still get the error about "can't find the

field..."
double-check your
form's recordsource to make sure the new path field is
in
there.

Mark, Thanks! I appreciate the detail steps. And
it's
embarrassing when I can't follow them!
I'm getting an error message: run-time error '2465'
Microsoft Access can't find the field 'FilePath'
referred
to in your expresion. I can't get from design view

to
form view because of it.

On my Animals table I added FilePath as a text

field.
And
in my Animals form (confusing names, I know) I added
the
picture (which I had to put a box around so I could
find
it!), deleted the actual picture/path and called the
field: ImageControl. Should the picture type
be "linked"
rather than "embedded"?

Private Sub Form_Current()
Me.ImageControl.Picture = Me!FilePath
End Sub

I don't understand why this didn't work.

So I commented it out, and then I get a compile

error:
expected variable or procedure, not module
and remembered to name the module: GetTheFilenamemdl
rather than GetTheFilename. See! I can be taught.

Now, it's not liking
Dim dlgFilePick As FileDialog
I've never seen FileDialog. This must be what you

Hi Michelle,

For testing, you can certainly just type in the full
path
(don't need
quotes) to the image (don't forget the file's
extension
like Dog1.jpg). On
the form, add an image and select any old image from
the
wizard. Once the
control is on the form, you can go to properties and
erase the file path in
the "Picture" property. Now you have a blank
(unbound)
image control.

In my test form I whipped up to refresh my memory, I
just
used the default
name of the control, which happened to be "Image7".
Since the file path is
saved with the record, you'll always get the correct
image for the record
being displayed.

When your user clicks on the image (or blank image

box
if
there's no image
assigned yet), the full filename with path is stored
in
the FilePath field
for that record and the form's recordset is

requeried
to
update the image.
The ImageControl's OnClick event:
'*********code start************
Private Sub ImageControl_Click()
Dim strFilename As String, strFind As String
Dim lngID As Long

strFilename = GetTheFilename("Browse to the

file")
If strFilename = "Cancelled" Then
Exit Sub
End If
Me!FilePath = strFilename
lngID = Me!ItemID
strFind = "[ItemID]=" & lngID
Echo False
Me.Requery
Me.Recordset.FindFirst strFind
Echo True

'********code end************

In a regular module (for the file requestor),
'********code start********
Function GetTheFilename(strTitle As String) As

String
Dim strFilename As String
Dim dlgFilePick As FileDialog
Dim vrtSelectedItem As Variant

On Error GoTo Err_GetFilename
Set dlgFilePick = Application.FileDialog
(msoFileDialogFilePicker)
With dlgFilePick
.Title = strTitle
'Let user select only one file
.AllowMultiSelect = False
If .Show = -1 Then
'The user pressed the action button.
GetTheFilename = .SelectedItems(1)

Else
'The user pressed Cancel.
GetTheFilename = "Cancelled"
End If
End With

Exit_GetFilename:
Set dlgFilePick = Nothing
Exit Function
Err_GetFilename:
MsgBox "Error " & Err.Number & ": " &
Err.Description, ,
"GetTheFilename"
Resume Exit_GetFilename
End Function
'********code end************

I'm using Access2003, so the file browser function
might
need tweaking for
older versions.
Hope this helps!

I like the sound of that! I only have 5 pictures

so
far
and they are slow to load.

I want to try it! I created a new text field
(FilePath)
in
table Animals. My file path for the 1st picture

is
C:\My Documents\My Pictures\Dog1
so I enter the above path in the Animals table,
FilePath
field for Dog1's record. Correct? Do I need the
file
path in quotes?

How do I create an unbound image control on the
form? I
see the tool bar offers "image", "unbound object
frame"
and a "bound object frame"- all of which want me

to
select
the image now. What am I missing to get an

unbound
image
control?

I'm confused about: Me.Image7.Picture = Me!

FilePath
Does Image7 mean something? Is that the name of
your
image in the record? If so, how does the record
know
which picture to show for which record- must be by
the
file path name...

You said "When you click the image control, the

user
browses to the picture they want to assign to the
current
record."- that sounds cool! So I set up the

unbound
image
control once in the table and then the user gets

to
choose
the picture, so that the user is never in the

table-
correct? That would be excellent!

Thanks for the guidance!

it has Record1's picture. Strange. I click "end"

rather
than "debug". Go on to Record 3 (no error getting

there
because Record3 has a path and a picture). Record4

(error-
no path/picture), click "end" and all the rest of my
records have no path but Record3's picture (the last
record with a picture). So, code is not happy when

there
is no picture attached to the Record, makes up it's

own
picture, and yells at me before I even have a chance

to
attach the picture. What did I do wrong now? I'm

feeling
it. Thanks, Mich

Or posts have crossed each other. If you look at my
previous (to this post)
post, you need to change the line where it checks to

see
if strFilename =
"Cancelled" to just checking if strFilename= "". The

new
functions don't
return "Cancelled" if you cancel the browser. Because
it's checking for
"Cancelled" and not seeing it, it continues the code

and
tries to store an
empty string in your table.

It looks like the little lightbulb over your head is
getting brighter and
brighter!

OK, now's the time to think not just paste!
Here's what I have:

Private Sub ImagePicture_Click()
Dim strFilename As String, strFind As String
Dim lngID As Long

'strFilename = GetTheFilename("Browse to the

file")
strFilename = GetOpenFile(, "Browse for a file")

If strFilename = "Cancelled" Then
Exit Sub
End If

'Me!FilePath = strFilename
Me!ImagePath = strFilename
'lngID = Me!ItemID
lngID = Me!AnimalsID
'strFind = "[ItemID]=" & lngID
strFind = "[AnimalsID]=" & lngID

Echo False
Me.Requery
Me.Recordset.FindFirst strFind
Echo True

End Sub

I was getting an error message that (I think)

strFind
was
zero length. But now I'm getting nothing- no error
message, no picture. Wait here's the error:
run-time error '3315' Field 'Animals.ImagePath'

cannot
be
a zero-length string.

I did make sure that ImagePath is in the record

source
and
that the text field is 50 characters to handle the

path.

I still must be doing something wrong. So close!
Thanks,
Michelle

Michelle,
Long ago, I was given a bunch of code which was

written
back in the Access97
days, which uses calls to the Windows components to

open
the file dialog.
I'm pasting it here, but be prepared for a long

bunch
of
code! Just copy
what's between the ***start copy*** and ***end

copy***.
Paste it into a new
module; mine was called modFileRequestor...
For your image_click event use this code instead of

what
I had befo
GetOpenFile(, "Browse for a file")

As for confusing names like table "Animals" and
form "Animals", I alway put
a three-character identifier on all my objects--
tblAnimals or frmAnimals or
qryAnimals, etc. Just for clarity, you might want

to
rename your field in
the table to "ImagePath", and maybe your image

control
on
the form to
"imgPicture". You shouldn't have to change the

image
property from
"embedded"; it won't matter since it's not being

saved
with the form. If
you still get the error about "can't find the

field..."
double-check your
form's recordsource to make sure the new path field

is
in
there.

Mark, Thanks! I appreciate the detail steps. And
it's
embarrassing when I can't follow them!
I'm getting an error message: run-time

error '2465'
Microsoft Access can't find the field 'FilePath'
referred
to in your expresion. I can't get from design

view
to
form view because of it.

On my Animals table I added FilePath as a text

field.
And
in my Animals form (confusing names, I know) I

added
the
picture (which I had to put a box around so I

could
find
it!), deleted the actual picture/path and called

the
field: ImageControl. Should the picture type
be "linked"
rather than "embedded"?

Private Sub Form_Current()
Me.ImageControl.Picture = Me!FilePath
End Sub

I don't understand why this didn't work.

So I commented it out, and then I get a compile

error:
expected variable or procedure, not module
and remembered to name the module:

GetTheFilenamemdl
rather than GetTheFilename. See! I can be taught.

Now, it's not liking
Dim dlgFilePick As FileDialog
I've never seen FileDialog. This must be what you
mentioned as tweaking the file browser function as

I'm
using Access 2000. So I took a peek in the

library
and
I
have these checked (and in this order):
VB for applications
Microsoft Access 9.0 object library
OLE Automation
Microsoft DAO 3.6 object library
Microsoft ActiveX Sata Objects 2.1 library

Am I salvagable? Thanks for your help, Michelle

Hi Michelle,

For testing, you can certainly just type in the

full
path
(don't need
quotes) to the image (don't forget the file's
extension
like Dog1.jpg). On
the form, add an image and select any old image

from
the
wizard. Once the
control is on the form, you can go to properties

and
erase the file path in
the "Picture" property. Now you have a blank
(unbound)
image control.

In my test form I whipped up to refresh my

memory, I
just
used the default
name of the control, which happened to

be "Image7".
Since the file path is
saved with the record, you'll always get the

correct
image for the record
being displayed.

When your user clicks on the image (or blank image

box
if
there's no image
assigned yet), the full filename with path is

stored
in
the FilePath field
for that record and the form's recordset is

requeried
to
update the image.
The ImageControl's OnClick event:
'*********code start************
Private Sub ImageControl_Click()
Dim strFilename As String, strFind As String
Dim lngID As Long

strFilename = GetTheFilename("Browse to the

file")
If strFilename = "Cancelled" Then
Exit Sub
End If
Me!FilePath = strFilename
lngID = Me!ItemID
strFind = "[ItemID]=" & lngID
Echo False
Me.Requery
Me.Recordset.FindFirst strFind
Echo True

'********code end************

In a regular module (for the file requestor),
'********code start********
Function GetTheFilename(strTitle As String) As

String
Dim strFilename As String
Dim dlgFilePick As FileDialog
Dim vrtSelectedItem As Variant

On Error GoTo Err_GetFilename
Set dlgFilePick = Application.FileDialog
(msoFileDialogFilePicker)
With dlgFilePick
.Title = strTitle
'Let user select only one file
.AllowMultiSelect = False
If .Show = -1 Then
'The user pressed the action button.
GetTheFilename = .SelectedItems(1)

Else
'The user pressed Cancel.
GetTheFilename = "Cancelled"
End If
End With

Exit_GetFilename:
Set dlgFilePick = Nothing
Exit Function
Err_GetFilename:
MsgBox "Error " & Err.Number & ": " &
Err.Description, ,
"GetTheFilename"
Resume Exit_GetFilename
End Function
'********code end************

I'm using Access2003, so the file browser function
might
need tweaking for
older versions.
Hope this helps!

I like the sound of that! I only have 5 pictures

so
far
and they are slow to load.

I want to try it! I created a new text field
(FilePath)
in
table Animals. My file path for the 1st picture

is
C:\My Documents\My Pictures\Dog1
so I enter the above path in the Animals table,
FilePath
field for Dog1's record. Correct? Do I need

the
file
path in quotes?

How do I create an unbound image control on the
form? I
see the tool bar offers "image", "unbound object
frame"
and a "bound object frame"- all of which want me

to
select
the image now. What am I missing to get an

unbound
image
control?

I'm confused about: Me.Image7.Picture = Me!

FilePath
Does Image7 mean something? Is that the name of
your
image in the record? If so, how does the record
know
which picture to show for which record- must be

by
the
file path name...

You said "When you click the image control, the

user
browses to the picture they want to assign to

the
current
record."- that sounds cool! So I set up the

unbound
image
control once in the table and then the user gets

to
choose
the picture, so that the user is never in the

table-
correct? That would be excellent!

Thanks for the guidance!
Michelle

I used to have an ID badge database that stored

the
digital pictures in an
OLE field. There was an OLE control on the form
which,
when clicked, would
let you browse to select the file. With only 100

or
so
employee records, the
database bloated to over 200Mb. I have since
modified
the database to get
rid of the OLE field and control. I'm now

storing
the
path to the picture
in a text field called FilePath and the database

is
under
200Kb. I've got
an unbound image control on the form, and in the
form's
OnCurrent event I
have:

Me.Image7.Picture = Me!FilePath

which will change the picture to match the

picture
you
assigned to the
current record. When you click the image

control,
the
user browses to the
picture they want to assign to the current

record.
It
works with both JPG
and BMP files.

Most excellent, Michelle. Glad to help. Sometimes the best way to learn
something is by trying and failing, then figuring out how to make it work.
It seems the hardest learned lessons are the ones we remember forever. Most
everything I know I owe to people that helped me when I asked, and the rest
was trial and error.

One last thing, if you want to, you can comment out everything in the
OnClick code after you've selected (or cancelled) the 'browse for picture'.
After a little playing around, it turns out you don't really need to requery
the database for the picture to show up. I guess I was doing it to
automatically save the record; if you don't requery, the record is still in
"edit mode". You can probably go the next step by giving the user the
option to clear a picture from the record by programming a command button to
update the record by setting the field value to Null.

Yeah, my brain is running out of steam. I think we need

to check for null
instead of empty:

If IsNull(Me.ImagePath) Then
Me.ImagePicture.Picture = ""
Else
Me.ImagePicture.Picture = Me.ImagePath
End If

I always have to play around with the IsNull vs ="" to

get certain things to
work right.

Hmm. I now have:

Me.ImagePicture.Picture = ""
Else
Me.ImagePicture.Picture = Me.ImagePath

End Sub

but it's still giving the same error. I'm on Record1
(path) and naviagte to Record2 (no real path), I get the
error and when I go to debug Me.ImagePicture.Picture =
Me.ImagePath is showing the path from Record1. I can't
tell if thinks it's on record1 or thinks record2 has
record1's path. In any case, it doesn't think it's null
when it is. Thanks, Mich

All you need to do is check to see if there's a path
stored, and if not just
set the Picture property to nothing:

If Me.ImagePath = "" Then
Me.ImagePicture.Picture = ""
Else
Me.ImagePicture.Picture = Me.ImagePath
End If

Yah, it's up to 40 watts now! Not quite room
temperature. But so appreciate the hand-holding!
My bad- I messed up my form by not saving one of the
modules when it asked me (several times), and I had to
create the form over- forgetting the on_current:
Me.ImagePicture.Picture = Me.ImagePath

Much better now- I have picture!! (it was so

exciting!)
but not quite right.

That very code:
Me.ImagePicture.Picture = Me.ImagePath
is giving me grief- run-time error '94' invalid use of
null.

I took the "." vs. "!" advice (nice), but didn't need

to
use Me.txtPath=strFilename. But I did check it out

and
liked the idea so I created a field to show the

picture
path- handy when we need to update the picture.

Anyway,
Record1 has a path and a picture. When I navigate to
Record2, I get the error, see that there is no path,

yet
it has Record1's picture. Strange. I click "end"

rather
than "debug". Go on to Record 3 (no error getting

there
because Record3 has a path and a picture). Record4
(error-
no path/picture), click "end" and all the rest of my
records have no path but Record3's picture (the last
record with a picture). So, code is not happy when

there
is no picture attached to the Record, makes up it's

own
picture, and yells at me before I even have a chance

to
attach the picture. What did I do wrong now? I'm
feeling
it. Thanks, Mich

-----Original Message-----
Or posts have crossed each other. If you look at my
previous (to this post)
post, you need to change the line where it checks to

see
if strFilename =
"Cancelled" to just checking if strFilename= "". The
new
functions don't
return "Cancelled" if you cancel the browser. Because
it's checking for
"Cancelled" and not seeing it, it continues the code

and
tries to store an
empty string in your table.

It looks like the little lightbulb over your head is
getting brighter and
brighter!

OK, now's the time to think not just paste!
Here's what I have:

Private Sub ImagePicture_Click()
Dim strFilename As String, strFind As String
Dim lngID As Long

strFilename = GetOpenFile(, "Browse for a file")

End Sub

I was getting an error message that (I think)

strFind
was
zero length. But now I'm getting nothing- no error
message, no picture. Wait here's the error:
run-time error '3315' Field 'Animals.ImagePath'

cannot
be

I did make sure that ImagePath is in the record

source
and
that the text field is 50 characters to handle the
path.

I still must be doing something wrong. So close!

Michelle,
Long ago, I was given a bunch of code which was
written
back in the Access97
days, which uses calls to the Windows components to
open
the file dialog.
I'm pasting it here, but be prepared for a long

bunch
of
code! Just copy
what's between the ***start copy*** and ***end
copy***.
Paste it into a new
module; mine was called modFileRequestor...
For your image_click event use this code instead of
what
I had befo
GetOpenFile(, "Browse for a file")

As for confusing names like table "Animals" and
form "Animals", I alway put
a three-character identifier on all my objects--
tblAnimals or frmAnimals or
qryAnimals, etc. Just for clarity, you might want

to
rename your field in
the table to "ImagePath", and maybe your image

control
on
the form to
"imgPicture". You shouldn't have to change the

image
property from
"embedded"; it won't matter since it's not being

saved
with the form. If
you still get the error about "can't find the
field..."
double-check your
form's recordsource to make sure the new path field

is
in
there.

Mark, Thanks! I appreciate the detail steps. And
it's
embarrassing when I can't follow them!
I'm getting an error message: run-time

error '2465'
Microsoft Access can't find the field 'FilePath'
referred
to in your expresion. I can't get from design

view
to
form view because of it.

On my Animals table I added FilePath as a text
field.
And
in my Animals form (confusing names, I know) I

added
the
picture (which I had to put a box around so I

could
find
it!), deleted the actual picture/path and called

the
field: ImageControl. Should the picture type
be "linked"
rather than "embedded"?

Private Sub Form_Current()
Me.ImageControl.Picture = Me!FilePath
End Sub

I don't understand why this didn't work.

So I commented it out, and then I get a compile
error:
expected variable or procedure, not module
and remembered to name the module:

GetTheFilenamemdl
rather than GetTheFilename. See! I can be taught.

Now, it's not liking
Dim dlgFilePick As FileDialog
I've never seen FileDialog. This must be what you
mentioned as tweaking the file browser function as
I'm
using Access 2000. So I took a peek in the

library
and
I
have these checked (and in this order):
VB for applications
Microsoft Access 9.0 object library
OLE Automation
Microsoft DAO 3.6 object library
Microsoft ActiveX Sata Objects 2.1 library

Am I salvagable? Thanks for your help, Michelle

Hi Michelle,

For testing, you can certainly just type in the

full
path
(don't need
quotes) to the image (don't forget the file's
extension
like Dog1.jpg). On
the form, add an image and select any old image

from
the
wizard. Once the
control is on the form, you can go to properties

and
erase the file path in
the "Picture" property. Now you have a blank
(unbound)
image control.

In my test form I whipped up to refresh my

memory, I
just
used the default
name of the control, which happened to

be "Image7".
Since the file path is
saved with the record, you'll always get the

correct
image for the record
being displayed.

When your user clicks on the image (or blank image
box
if
there's no image
assigned yet), the full filename with path is

stored
in
the FilePath field
for that record and the form's recordset is
requeried
to
update the image.
The ImageControl's OnClick event:
'*********code start************
Private Sub ImageControl_Click()
Dim strFilename As String, strFind As String
Dim lngID As Long

strFilename = GetTheFilename("Browse to the
file")
If strFilename = "Cancelled" Then
Exit Sub
End If
Me!FilePath = strFilename
lngID = Me!ItemID
strFind = "[ItemID]=" & lngID
Echo False
Me.Requery
Me.Recordset.FindFirst strFind
Echo True

'********code end************

In a regular module (for the file requestor),
'********code start********
Function GetTheFilename(strTitle As String) As
String
Dim strFilename As String
Dim dlgFilePick As FileDialog
Dim vrtSelectedItem As Variant

On Error GoTo Err_GetFilename
Set dlgFilePick = Application.FileDialog
(msoFileDialogFilePicker)
With dlgFilePick
.Title = strTitle
'Let user select only one file
.AllowMultiSelect = False
If .Show = -1 Then
'The user pressed the action button.
GetTheFilename = .SelectedItems(1)

Else
'The user pressed Cancel.
GetTheFilename = "Cancelled"
End If
End With

Exit_GetFilename:
Set dlgFilePick = Nothing
Exit Function
Err_GetFilename:
MsgBox "Error " & Err.Number & ": " &
Err.Description, ,
"GetTheFilename"
Resume Exit_GetFilename
End Function
'********code end************

I'm using Access2003, so the file browser function
might
need tweaking for
older versions.
Hope this helps!

I like the sound of that! I only have 5 pictures
so
far
and they are slow to load.

I want to try it! I created a new text field
(FilePath)
in
table Animals. My file path for the 1st picture
is
C:\My Documents\My Pictures\Dog1
so I enter the above path in the Animals table,
FilePath
field for Dog1's record. Correct? Do I need

the
file
path in quotes?

How do I create an unbound image control on the
form? I
see the tool bar offers "image", "unbound object
frame"
and a "bound object frame"- all of which want me
to
select
the image now. What am I missing to get an
unbound
image
control?

I'm confused about: Me.Image7.Picture = Me!
FilePath
Does Image7 mean something? Is that the name of
your
image in the record? If so, how does the record
know
which picture to show for which record- must be

by
the
file path name...

You said "When you click the image control, the
user
browses to the picture they want to assign to

the
current
record."- that sounds cool! So I set up the
unbound
image
control once in the table and then the user gets
to
choose
the picture, so that the user is never in the
table-
correct? That would be excellent!

Thanks for the guidance!
Michelle

I used to have an ID badge database that stored
the
digital pictures in an
OLE field. There was an OLE control on the form
which,
when clicked, would
let you browse to select the file. With only 100
or
so
employee records, the
database bloated to over 200Mb. I have since
modified
the database to get
rid of the OLE field and control. I'm now

storing
the
path to the picture
in a text field called FilePath and the database
is
under
200Kb. I've got
an unbound image control on the form, and in the
form's
OnCurrent event I
have:

Me.Image7.Picture = Me!FilePath

which will change the picture to match the

picture
you
assigned to the
current record. When you click the image

control,
the
user browses to the
picture they want to assign to the current

record.
It
works with both JPG
and BMP files.

Sorry about that!
I have form that I want to show a digital

camera
picture.
I have the table field set up as an OLE

Object.

Can I load the picture from the form, or do I
need
to
go
to the table, find the correct record for the
field,
select Insert object and the browse to the
correct
digital
camera picture? There's got to be an easier

way
for

I see that bitmap is an option, but my digital
camera
pictures are jpg. How do I upload these?

Thanks,

Thanks. I think I'll leave it as is- since the user isn't
creating a new record, I worry that they'll forget to
save. I did discover that with my text field to show the
path- if I erase that path, the picture disappears, or of
course, they can just upload a new picture.

Thanks for all of the encouragement. I've learned so much
from the newsgroup but feel that I'll never know enough!
I'm certainly enjoying the journey- both the trial and
error and from kind folks like you providing the code and
then trying to figure it out. Cheers! Mich

Most excellent, Michelle. Glad to help. Sometimes the

best way to learn
something is by trying and failing, then figuring out how

to make it work.
It seems the hardest learned lessons are the ones we

remember forever. Most
everything I know I owe to people that helped me when I

asked, and the rest
was trial and error.

One last thing, if you want to, you can comment out

everything in the
OnClick code after you've selected (or cancelled)

the 'browse for picture'.
After a little playing around, it turns out you don't

really need to requery
the database for the picture to show up. I guess I was

doing it to
automatically save the record; if you don't requery, the

record is still in
"edit mode". You can probably go the next step by giving

the user the
option to clear a picture from the record by programming

a command button to
update the record by setting the field value to Null.

Yeah, my brain is running out of steam. I think we need

to check for null
instead of empty:

If IsNull(Me.ImagePath) Then
Me.ImagePicture.Picture = ""
Else
Me.ImagePicture.Picture = Me.ImagePath
End If

I always have to play around with the IsNull vs ="" to

get certain things to
work right.

Hmm. I now have:

Private Sub Form_Current()
If Me.ImagePath = "" Then
Me.ImagePicture.Picture = ""
Else
Me.ImagePicture.Picture = Me.ImagePath
End If
End Sub

but it's still giving the same error. I'm on Record1
(path) and naviagte to Record2 (no real path), I get

the
error and when I go to debug Me.ImagePicture.Picture

=
Me.ImagePath is showing the path from Record1. I

can't
tell if thinks it's on record1 or thinks record2 has
record1's path. In any case, it doesn't think it's

null
when it is. Thanks, Mich

-----Original Message-----
All you need to do is check to see if there's a path
stored, and if not just
set the Picture property to nothing:

If Me.ImagePath = "" Then
Me.ImagePicture.Picture = ""
Else
Me.ImagePicture.Picture = Me.ImagePath
End If

Yah, it's up to 40 watts now! Not quite room
temperature. But so appreciate the hand-holding!
My bad- I messed up my form by not saving one of the
modules when it asked me (several times), and I had

to
create the form over- forgetting the on_current:
Me.ImagePicture.Picture = Me.ImagePath

Much better now- I have picture!! (it was so

exciting!)
but not quite right.

That very code:
Me.ImagePicture.Picture = Me.ImagePath
is giving me grief- run-time error '94' invalid use

of
null.

I took the "." vs. "!" advice (nice), but didn't

need
to
use Me.txtPath=strFilename. But I did check it out

and
liked the idea so I created a field to show the

picture
path- handy when we need to update the picture.

Anyway,
Record1 has a path and a picture. When I navigate

to
Record2, I get the error, see that there is no path,

yet
it has Record1's picture. Strange. I click "end"

rather
than "debug". Go on to Record 3 (no error getting

there
because Record3 has a path and a picture). Record4
(error-
no path/picture), click "end" and all the rest of my
records have no path but Record3's picture (the last
record with a picture). So, code is not happy when

there
is no picture attached to the Record, makes up it's

own
picture, and yells at me before I even have a chance

to
attach the picture. What did I do wrong now? I'm
feeling
it. Thanks, Mich

-----Original Message-----
Or posts have crossed each other. If you look at my
previous (to this post)
post, you need to change the line where it checks to

see
if strFilename =
"Cancelled" to just checking if strFilename= "".

The
new
functions don't
return "Cancelled" if you cancel the browser.

Because
it's checking for
"Cancelled" and not seeing it, it continues the code

and
tries to store an
empty string in your table.

It looks like the little lightbulb over your head is
getting brighter and
brighter!

OK, now's the time to think not just paste!
Here's what I have:

Private Sub ImagePicture_Click()
Dim strFilename As String, strFind As String
Dim lngID As Long

'strFilename = GetTheFilename("Browse to the

file")
strFilename = GetOpenFile(, "Browse for a

file")

If strFilename = "Cancelled" Then
Exit Sub
End If

'Me!FilePath = strFilename
Me!ImagePath = strFilename
'lngID = Me!ItemID
lngID = Me!AnimalsID
'strFind = "[ItemID]=" & lngID
strFind = "[AnimalsID]=" & lngID

Echo False
Me.Requery
Me.Recordset.FindFirst strFind
Echo True

End Sub

I was getting an error message that (I think)

strFind
was
zero length. But now I'm getting nothing- no

error
message, no picture. Wait here's the error:
run-time error '3315' Field 'Animals.ImagePath'

cannot
be
a zero-length string.

I did make sure that ImagePath is in the record

source
and
that the text field is 50 characters to handle the
path.

I still must be doing something wrong. So close!

Michelle,
Long ago, I was given a bunch of code which was
written
back in the Access97
days, which uses calls to the Windows components

to
open
the file dialog.
I'm pasting it here, but be prepared for a long

bunch
of
code! Just copy
what's between the ***start copy*** and ***end
copy***.
Paste it into a new
module; mine was called modFileRequestor...
For your image_click event use this code instead

of
what
I had befo
GetOpenFile(, "Browse for a file")

As for confusing names like table "Animals" and
form "Animals", I alway put
a three-character identifier on all my objects--
tblAnimals or frmAnimals or
qryAnimals, etc. Just for clarity, you might want

to
rename your field in
the table to "ImagePath", and maybe your image

control
on
the form to
"imgPicture". You shouldn't have to change the

image
property from
"embedded"; it won't matter since it's not being

saved
with the form. If
you still get the error about "can't find the
field..."
double-check your
form's recordsource to make sure the new path

field
is
in
there.

Mark, Thanks! I appreciate the detail steps.

And
it's
embarrassing when I can't follow them!
I'm getting an error message: run-time

error '2465'
Microsoft Access can't find the field 'FilePath'
referred
to in your expresion. I can't get from design

view
to
form view because of it.

On my Animals table I added FilePath as a text
field.
And
in my Animals form (confusing names, I know) I

added
the
picture (which I had to put a box around so I

could
find
it!), deleted the actual picture/path and called

the
field: ImageControl. Should the picture type
be "linked"
rather than "embedded"?

Private Sub Form_Current()
Me.ImageControl.Picture = Me!FilePath
End Sub

I don't understand why this didn't work.

So I commented it out, and then I get a compile
error:
expected variable or procedure, not module
and remembered to name the module:

GetTheFilenamemdl
rather than GetTheFilename. See! I can be

taught.

Now, it's not liking
Dim dlgFilePick As FileDialog
I've never seen FileDialog. This must be what

you
mentioned as tweaking the file browser function

as
I'm
using Access 2000. So I took a peek in the

library
and
I
have these checked (and in this order):
VB for applications
Microsoft Access 9.0 object library
OLE Automation
Microsoft DAO 3.6 object library
Microsoft ActiveX Sata Objects 2.1 library

Am I salvagable? Thanks for your help, Michelle

Hi Michelle,

For testing, you can certainly just type in the

full
path
(don't need
quotes) to the image (don't forget the file's
extension
like Dog1.jpg). On
the form, add an image and select any old image

from
the
wizard. Once the
control is on the form, you can go to properties

and
erase the file path in
the "Picture" property. Now you have a blank
(unbound)
image control.

In my test form I whipped up to refresh my

memory, I
just
used the default
name of the control, which happened to

be "Image7".
Since the file path is
saved with the record, you'll always get the

correct
image for the record
being displayed.

When your user clicks on the image (or blank

image
box
if
there's no image
assigned yet), the full filename with path is

stored
in
the FilePath field
for that record and the form's recordset is
requeried
to
update the image.
The ImageControl's OnClick event:
'*********code start************
Private Sub ImageControl_Click()
Dim strFilename As String, strFind As String
Dim lngID As Long

strFilename = GetTheFilename("Browse to the
file")
If strFilename = "Cancelled" Then
Exit Sub
End If
Me!FilePath = strFilename
lngID = Me!ItemID
strFind = "[ItemID]=" & lngID
Echo False
Me.Requery
Me.Recordset.FindFirst strFind
Echo True

'********code end************

In a regular module (for the file requestor),
'********code start********
Function GetTheFilename(strTitle As String) As
String
Dim strFilename As String
Dim dlgFilePick As FileDialog
Dim vrtSelectedItem As Variant

On Error GoTo Err_GetFilename
Set dlgFilePick = Application.FileDialog
(msoFileDialogFilePicker)
With dlgFilePick
.Title = strTitle
'Let user select only one file
.AllowMultiSelect = False
If .Show = -1 Then
'The user pressed the action button.
GetTheFilename = .SelectedItems(1)

Else
'The user pressed Cancel.
GetTheFilename = "Cancelled"
End If
End With

Exit_GetFilename:
Set dlgFilePick = Nothing
Exit Function
Err_GetFilename:
MsgBox "Error " & Err.Number & ": " &
Err.Description, ,
"GetTheFilename"
Resume Exit_GetFilename
End Function
'********code end************

I'm using Access2003, so the file browser

function
might
need tweaking for
older versions.
Hope this helps!

I like the sound of that! I only have 5

pictures
so
far
and they are slow to load.

I want to try it! I created a new text field
(FilePath)
in
table Animals. My file path for the 1st

picture
is
C:\My Documents\My Pictures\Dog1
so I enter the above path in the Animals

table,
FilePath
field for Dog1's record. Correct? Do I need

the
file
path in quotes?

How do I create an unbound image control on

the
form? I
see the tool bar offers "image", "unbound

object
frame"
and a "bound object frame"- all of which want

me
to
select
the image now. What am I missing to get an
unbound
image
control?

I'm confused about: Me.Image7.Picture = Me!
FilePath
Does Image7 mean something? Is that the name

of
your
image in the record? If so, how does the

record
know
which picture to show for which record- must

be
by
the
file path name...

You said "When you click the image control,

the
user
browses to the picture they want to assign to

the
current
record."- that sounds cool! So I set up the
unbound
image
control once in the table and then the user

gets
to
choose
the picture, so that the user is never in the
table-
correct? That would be excellent!

Thanks for the guidance!
Michelle

I used to have an ID badge database that

stored
the
digital pictures in an
OLE field. There was an OLE control on the

form
which,
when clicked, would
let you browse to select the file. With only

100
or
so
employee records, the
database bloated to over 200Mb. I have since
modified
the database to get
rid of the OLE field and control. I'm now

storing
the
path to the picture
in a text field called FilePath and the

database
is
under
200Kb. I've got
an unbound image control on the form, and in

the
form's
OnCurrent event I
have:

Me.Image7.Picture = Me!FilePath

which will change the picture to match the

picture
you
assigned to the
current record. When you click the image

control,
the
user browses to the
picture they want to assign to the current

record.
It
works with both JPG
and BMP files.

Sorry about that!
I have form that I want to show a digital

camera
picture.
I have the table field set up as an OLE

Object.

Can I load the picture from the form, or do

I
need
to
go
to the table, find the correct record for

the
field,
select Insert object and the browse to the
correct
digital
camera picture? There's got to be an easier

way
for
end-
users!

I see that bitmap is an option, but my

digital
camera
pictures are jpg. How do I upload these?

Thanks,
Mich

Michelle I'm sure everyone is happy you were able to work through your
issue with some excellent help in this NG. Just a note, the last 13
messages in this thread generated more than 325KB of network traffic
simply because neither of you took the time to trim the repetitive
portions of this thread.

Not everyone reading this NG has a broadband connection. NG Etiquette
suggests that when you reply take a moment to snip out repetitive or non

Thanks. I think I'll leave it as is- since the user isn't
creating a new record, I worry that they'll forget to
save. I did discover that with my text field to show the
path- if I erase that path, the picture disappears, or of
course, they can just upload a new picture.
