Moderate: Requires basic macro, coding, and interoperability skills.
SUMMARY
When you move to the next record on a form or close a form, Microsoft
Access automatically saves any changes that you have made to the current
record. This article shows you how to use a BeforeUpdate event procedure to
prompt you to verify the save operation before Microsoft Access will
continue.

MORE INFORMATIONCAUTION: Following the steps in this example will modify the sample
database Northwind.mdb. You may want to back up the Northwind.mdb file
and perform these steps on a copy of the database.
This example uses the BeforeUpdate event procedure in the Customers form to
prompt the user to confirm changes before Microsoft Access will save the
record:
- Open the sample database Northwind.mdb, and open the Customers form in Design view.
- Set the form's BeforeUpdate property to the following event procedure:
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
End If
Exit_BeforeUpdate:
Exit Sub
Err_BeforeUpdate:
MsgBox Err.Number & " " & Err.Description
Resume Exit_BeforeUpdate
End Sub
- On the Debug menu, click Compile Northwind.
- On the File menu, click Save Northwind.
- On the File menu, click Close And Return to Microsoft Access.
Now, when you make a change to a record, and then you either move to a
different record or close the form, you are prompted to confirm that you
want to save the current record. If you click No, the record is reset and the operation continues as normal.
