Default User Logins & Access Levels

"Jeff Monroe" wrote in message
...

I have a database where I have customized the user login function. My
table (tblEmployees) contains four fields (lngEmpID, strEmpName,
strEmpPassword, strAccess). When launched, the user selects their
EmpName from a combo-box and enters their EmpPassword.

What I cannot figure out is how to get their Access (access level:
Admin, User, Viewer) from tblEmployee and use it to limit buttons,
forms and user data (allow the user to edit their data in a form, but
not see other's).

I tried using DLookup() in the form Load event:

('strAccessLevel = DLookup("[strAccess]", "[tblEmployees]", "lngEmpID =
lngMyEmpID"))

But I appear to be way off. I am trying to use lngEmpID determined at
login (lngMyEmpID is a variable set in a separate module).

How do I get the data from Access (field in tblEmployees) to use in a
form's Load event in order to limit button, form access to non-Admin
users? How do I filter tblEmployee data in form based on the EmpID or
EmpName logged in?


DLookup("[strAccess]", "[tblEmployees]", "lngEmpID =" & lngMyEmpID)

I should also point out that "home-grown" security like you are attempting is SO
easily bypassed by people who are familiar with Access that it is usually a big
waste of time. For example you do know that the table containing all user names
and passwords could simply be imported or linked to from another file, right?
