Hello,
I was using the following code on a field (ItemCode) that was indexed to prevent duplication of records. The intent is that the user will get an error message that a duplicate exists before they enter all the data for the record and get the built in error message that Access 2003 provides when an index violation has occurred.
Code:
Private Sub ItemCode_BeforeUpdate(Cancel As Integer)
Dim Answer As Variant
Answer = DLookup("[ItemCode]", "tblQuestions", "[ItemCode] = '" & Me.ItemCode & "'")
If Not IsNull(Answer) Then
MsgBox "Item Code already exists" & vbCrLf & "Please enter unique Item Code.", vbCritical + vbOKOnly + vbDefaultButton1, "Duplicate"
Cancel = True
Me.ItemCode.Undo
Else:
End If
End Sub
Now, the index for this is based on two fields (ItemCode and Question Group). I would like to display the same message before update but don't know how to include the second field in the syntax.
Anybody know a solution?
Thanks,
