ACC2000: How to Prompt User to Save Changes to Record in a Form

• Microsoft Access 2000

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 INFORMATION

CAUTION: 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:

1. Open the sample database Northwind.mdb, and open the Customers form in Design view.



2. 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 

3. On the Debug menu, click Compile Northwind.
