I found a password login system for Access and copied it to aon click
event on a form in Access 2007, but there is an error in the coding.

I have created a tblEmployees with the following fields:
IngEmpID
strEmpName
strEmpPassword
Then I put a unbound combo box on a form with the username and password
fields. The combo box gets a list from strEmpName in the tblEmployees

I then copied the code given into the on click event of the cmd button:
BUT there is a Compile error 'variable not defined' IngMyEmpID, as
shown below

'Check to see if data is entered into the UserName combo box

If IsNull(Me.cboEmployee) Or Me.cboEmployee = "" Then
MsgBox "You must enter a User Name.", vbOKOnly, "Required Data"
Me.cboEmployee.SetFocus
Exit Sub
End If

'Check to see if data is entered into the password box

If IsNull(Me.txtPassword) Or Me.txtPassword = "" Then
MsgBox "You must enter a Password.", vbOKOnly, "Required Data"
Me.txtPassword.SetFocus
Exit Sub
End If

'Check value of password in tblEmployees to see if this
'matches value chosen in combo box

If Me.txtPassword.Value = DLookup("strEmpPassword", "tblEmployees", _
"[lngEmpID]=" & Me.cboEmployee.Value) Then

lngMyEmpID = Me.cboEmployee.Value <
BUT here there is a Compile error 'variable not defined' IngMyEmpID

'Close logon form and open splash screen

DoCmd.Close acForm, "frmLogon", acSaveNo
DoCmd.OpenForm "frmSplash_Screen"

Else
MsgBox "Password Invalid. Please Try Again", vbOKOnly, _
"Invalid Entry!"
Me.txtPassword.SetFocus
End If

'If User Enters incorrect password 3 times database will shutdown

intLogonAttempts = intLogonAttempts + 1
If intLogonAttempts > 3 Then
MsgBox "You do not have access to this database.Please contact
admin.", _
vbCritical, "Restricted Access!"
Application.Quit
End If

Thanks

Have you declared lngMyEmpID in your code?

I.e. do you have the following statement anywhere?

Dim lngMyEmpID As Long

I didn't actually, thanks.

But now I get another Runtime error '2471':
The expression you entered as a query paramter produced this error:
IngMyEmpID

And when I debug, this is highlighted:

If Me.txtPassword.Value = DLookup("strEmpPassword", "tblEmployees", _
"lngMyEmpID=" & Me.cboEmployee.Value) Then

Thanks

Apologies, I missed out the square brackets, but the error is still the
same.

I have just found that I need to create a module and put this line in it

Public lngMyEmpID As Long

So when that is done how does it link to the form or button.

Thanks
