   Private Sub Form_BeforeUpdate(Cancel As Integer)
   
      ' This procedure checks to see if the data on the form has
      ' changed. If the data has changed, the procedure prompts the
      ' user to continue with the save operation or to cancel it. Then
      ' the action that triggered the BeforeUpdate event is completed.
   
      Dim ctl As Control
   
      On Error GoTo Err_BeforeUpdate
   
      ' The Dirty property is True if the record has been changed.
      If Me.Dirty Then
         ' Prompt to confirm the save operation.
         If MsgBox("Do you want to save?", vbYesNo + vbQuestion, _
                 "Save Record") = vbNo Then
            Me.Undo
         End If
