I\'m sure this is very simple, but I can\'t find it. In the close event of an Access Form, how can I cancel closing the form? I have a test that counts the records in a tab

    Use the "Form_BeforeUpdate(cancel as integer)" event and set cancel to True.

    Notice that you simply will not be able to close at all unless you add some logic to actually allow updating the database.

    Study and try this code, it worked for me. Replace necessary variable names with your chosen names. Paste the code in the form_unload Event of your form. WARNING!!!: After you perform this operation you will find it difficult to access your form in design and layout view

        Private Sub Form_Unload(Cancel As Integer)
            userresponse = MsgBox("Are you sure you want close? All your work wouldn't be saved", vbYesNo, "Database Information")
            Select Case userresponse
            Case 6
                Cancel = False
                'this line opens another form in my own case
                DoCmd.OpenForm "EngMenu"  
    
            Case 7
                Cancel = True
                'this line keeps my own form open in my own case
                DoCmd.OpenForm "UpdateForm"
    
    
            Case Else:
    
                MsgBox "You are not allowed to perform this operation", vbInformation, "Database Information"
            End Select
        End Subenter code here

    You can use the Unload event:

    GlobalVar ButtonClicked
    
    Private Sub Form_Open(Cancel As Integer)
         ButtonClicked = False
    End Sub
    
    Private ClickMe_Click(Cancel As Integer)
         ButtonClicked = True
    End Sub
    
    Private Sub Form_Unload(Cancel As Integer)
         If Not ButtonClicked Then
             Cancel = True
         End if
    End Sub  
    

    Order of events for database objects
