Value is Negative Code Problem!

My problem is that the Text Box (Text377) is not bound, (is is a computed
field)
it simply equals the balance from the sub-form. Text377 is on the main form
and Balance from where it gets it's computed
total is located in the form footer of the sub-form.
Balance on sub-form is in format currency and it's control sorce is
=IIf(IsNull([SumPayment]),[OrderAmtA],[OrderAmtA]-[SumPayment])

Text377 control source is
=[FPaymentSub].[Form]![Balance]

I can't reproduce this. I created a table with two fields, one long
integer, one text. I created a form with a text box and a label, and added
the following code to the AfterUpdate event procedure of the text box ...

Private Sub txtTest_AfterUpdate()

Me!lblTest.Visible = (Val(Nz(Me!txtTest, 0)) 0)

End Sub

I tested first with the text box bound to the long integer field, and then
with the text box bound to the text field. If I enter -1 or 0, the label
is hidden, if I enter 1, the label is shown, as expected. Next, I changed
the operator from the greater than to the less than operator ...

Private Sub txtTest_AfterUpdate()

Me!lblTest.Visible = (Val(Nz(Me!txtTest, 0)) 0)

End Sub

Now if I enter -1 the label is shown, if I enter 0 or 1, the label is
hidden, as expected. Again, tested with the control bound first to the
long integer field, then the text field, with the same result.

Is it possible that the value is being treated as text? In a textual
comparison, "-1" "0" = True. What if you wrapped Val() around the
value to make sure it is treated as a number? Something like
YourControl.Visible = (Val(NZ(YourField, 0)) 0)

0 it does not show up???
This has something with it being a negative number, dont know how to

OK, here is my dilemna, I have a generic form I am using to test this
with no record source.
The TextBoxes have no control source other than the one I use to
subtract one amount from another to.
Everything works fine via this form, but when I try to use it on my
main form in th real db, it does not work. All the fields are the
same as the mock db except they do have a record source.
Here is the code I am using for the mock DB
More Details. The main form is named Timecards and the sub-form is
named TimeCardPaymentSub
The main form has the Text377 on it which gets it's computed data
from the sub-form Form Footer Text Box named Balance.
The main form also has the Label30 on it.
The Text Box Balance has it's control source set to the sub-form
TimeCardPaymentSub with this calculation.
=IIf(IsNull([SumPayment]),[OrderAmtA],[OrderAmtA]-[SumPayment])
Hope this explains better, I am lost...

If IsNull([Text377]) Then ' This is on the current event of the
main form.
Label30.Visible = False
Else
Label30.Visible = ([Text377] 0)
End If


If IsNull([Text377]) Then , This is on the sub-form after
update event.
Label30.Visible = False
Else
Label30.Visible = ([Text377] 0)
End If

Text377 is a computed value from another sub-form textbox.
If Text377 is a negative, i.e. Less Than Zero
Then Label30 should be visible
This code is on the current event of main form, it does not work.

If (Text377) = 0 Then
Label30.Visible = False
Else
Label30.Visible = (Text377) 0
End If

Please try this and tell me if it works:

With Me!Text377
.Requery
Me!Label30.Visible = (.Value 0)
End With

Okay, let's see what we can do with this information.

Create the following procedure in the General section of the main
form's
module. Note that the subroutine is declared as Public:

'---- start of function code ----
Public Sub SetLabelVisibility()

With Me!Text377

' The following statement may not be necessary.
' After everything is working, take it out to see.
.Requery

If IsError(.Value) Then
Me!Label30.Visible = False
Else
Me!Label30.Visible = (Nz(.Value, 0) 0)
End If

End With

End Sub
'---- start of function code ----

Now we need to call this function in every event that might cause the
value of Text377 to change. As far as I can see, these are (a) the
Current event of the main form, (b) the AfterUpdate event of the
subform, and (c) the AfterDelConfirm event of the subform. I may have
missed something, since I don't have your form in front of me. So you
need the following event procedures.

'---- event procedure for main form's Current event ----
Private Sub Form_Current()

SetLabelVisibility

End Sub
'---- end event procedure for main form' Current event ----


'---- event procedure for subform's AfterUpdate event ----
Private Sub Form_AfterUpdate()

Me.Parent.SetLabelVisibility

End Sub
'---- end event procedure for subform's AfterUpdate event ----


'---- event procedure for subform's AfterDelConfirm event ----
Private Sub Form_AfterUpdate()

Me.Parent.SetLabelVisibility

End Sub
'---- end event procedure for subform's AfterDelConfirm event ----

Now, I haven't tested this but something along these lines ought to
work -- at least, I think it should if the Balance text box on the
subform doesn't contain #ERROR.

I tried changing the control source of the text box to an expression, and
moving the code to the current event of the form, with the same result - the
code works as expected. I'm afraid I don't have time to reproduce your
form/subform setup right now, if you're still stuck I'll try to get to that
tomorrow if I can.

comparison, "-1" "0" = True. What if you wrapped Val() around the
value to make sure it is treated as a number? Something like
YourControl.Visible = (Val(NZ(YourField, 0)) 0)

This has something with it being a negative number, dont know how to

OK, here is my dilemna, I have a generic form I am using to test
this
with no record source.
The TextBoxes have no control source other than the one I use to
subtract one amount from another to.
Everything works fine via this form, but when I try to use it on
my
main form in th real db, it does not work. All the fields are the
same as the mock db except they do have a record source.
Here is the code I am using for the mock DB
More Details. The main form is named Timecards and the sub-form is
named TimeCardPaymentSub
The main form has the Text377 on it which gets it's computed data
from the sub-form Form Footer Text Box named Balance.
The main form also has the Label30 on it.
The Text Box Balance has it's control source set to the sub-form
TimeCardPaymentSub with this calculation.
=IIf(IsNull([SumPayment]),[OrderAmtA],[OrderAmtA]-[SumPayment])
Hope this explains better, I am lost...

If IsNull([Text377]) Then ' This is on the current event of
the
main form.
Label30.Visible = False
Else
Label30.Visible = ([Text377] 0)
End If


If IsNull([Text377]) Then , This is on the sub-form
after
update event.
Label30.Visible = False
Else
Label30.Visible = ([Text377] 0)
End If

Text377 is a computed value from another sub-form textbox.
If Text377 is a negative, i.e. Less Than Zero
Then Label30 should be visible
This code is on the current event of main form, it does not
work.

If (Text377) = 0 Then
Label30.Visible = False
Else
Label30.Visible = (Text377) 0
End If

Please try this and tell me if it works:

With Me!Text377
.Requery
Me!Label30.Visible = (.Value 0)
End With

Okay, let's see what we can do with this information.

Create the following procedure in the General section of the main
form's
module. Note that the subroutine is declared as Public:

'---- start of function code ----
Public Sub SetLabelVisibility()

With Me!Text377

' The following statement may not be necessary.
' After everything is working, take it out to see.
.Requery

If IsError(.Value) Then
Me!Label30.Visible = False
Else
Me!Label30.Visible = (Nz(.Value, 0) 0)
End If

End With

End Sub
'---- start of function code ----

Now we need to call this function in every event that might cause
the
value of Text377 to change. As far as I can see, these are (a) the
Current event of the main form, (b) the AfterUpdate event of the
subform, and (c) the AfterDelConfirm event of the subform. I may
have
missed something, since I don't have your form in front of me. So
you
need the following event procedures.

'---- event procedure for main form's Current event ----
Private Sub Form_Current()

SetLabelVisibility

End Sub
'---- end event procedure for main form' Current event ----


'---- event procedure for subform's AfterUpdate event ----
Private Sub Form_AfterUpdate()

Me.Parent.SetLabelVisibility

End Sub
'---- end event procedure for subform's AfterUpdate event ----


'---- event procedure for subform's AfterDelConfirm event ----
Private Sub Form_AfterUpdate()

Me.Parent.SetLabelVisibility

End Sub
'---- end event procedure for subform's AfterDelConfirm event ----

Now, I haven't tested this but something along these lines ought to
work -- at least, I think it should if the Balance text box on the
subform doesn't contain #ERROR.

It appears to be a timing issue. It seems that Access has not finished
calculating the balance when the Current event fires. I modified the code in
the form's Current event procedure as follows ...

Private Sub Form_Current()

Call EnableCtl

'Me!Label30.Visible = (Val(Nz(Me!Text377, 0)) 0)
Me.TimerInterval = 1000

End Sub

.... and moved the line that sets the visible property of the control to the
Timer event procedure as follows ...

Private Sub Form_Timer()

Me.TimerInterval = 0
Me!Label30.Visible = (Val(Nz(Me!Text377, 0)) 0)

End Sub

This code works as expected, the label is visible only when the balance is
negative.

I know the above is not an ideal solution, what I was primarily attempting
to do with the above code was to test my theory that the problem was a
timing issue. The result of the test does appear to support that theory. If
you could find a more efficient way of performing the calculation, I believe
that would solve the problem, but I'm afraid I don't have any specific
suggestions along those lines right now.

I tried changing the control source of the text box to an expression, and
moving the code to the current event of the form, with the same result -
the code works as expected. I'm afraid I don't have time to reproduce your
form/subform setup right now, if you're still stuck I'll try to get to
that tomorrow if I can.

My problem is that the Text Box (Text377) is not bound, (is is a
computed field)
it simply equals the balance from the sub-form. Text377 is on the main
form and Balance from where it gets it's computed
total is located in the form footer of the sub-form.
Balance on sub-form is in format currency and it's control sorce is
=IIf(IsNull([SumPayment]),[OrderAmtA],[OrderAmtA]-[SumPayment])

Text377 control source is
=[FPaymentSub].[Form]![Balance]

I can't reproduce this. I created a table with two fields, one long
integer, one text. I created a form with a text box and a label, and
added the following code to the AfterUpdate event procedure of the text
box ...

Private Sub txtTest_AfterUpdate()

Me!lblTest.Visible = (Val(Nz(Me!txtTest, 0)) 0)

End Sub

I tested first with the text box bound to the long integer field, and
then with the text box bound to the text field. If I enter -1 or 0, the
label is hidden, if I enter 1, the label is shown, as expected. Next, I
changed the operator from the greater than to the less than operator
...

Private Sub txtTest_AfterUpdate()

Me!lblTest.Visible = (Val(Nz(Me!txtTest, 0)) 0)

End Sub

Now if I enter -1 the label is shown, if I enter 0 or 1, the label is
hidden, as expected. Again, tested with the control bound first to the
long integer field, then the text field, with the same result.

Thanks, I believe you are right. I must concentrate as well on getting the
db to respond faster especially since it is on a network.
