How to handle close window event?

[abhiab54]

Hi all,
Can anyone tell me which event get generated when I close window
(e.g. of Form1) by cliking on its close button 'X' on rt handside on top of window.
I need to execute perticular code when I close the window.

Put your code in Form_QueryUnload event.

Put your code in Form_QueryUnload event.

Yes, use the QueryUnload event if you want to have the option of cancelling (stopping) the unload. You can also place code in the Unload event (which fires after QueryUnload), but at that point you don't have the option to cancel the close.

One nice thing about QueryUnload is that you receive a parameter telling you how/why the close was requested. So you can react differently depending on whether the user closed the form, or your code did it, or Windows is shutting down.

We can use Form_Unload to cancel colseing form

dim boolClose  as Boolean
 
Private Sub Form_Unload(Cancel As Integer)
    If boolClose = True Then
        Cancel = 0
        cmdClose_Click
    Else
        Cancel = 1
    End If
End Sub

Sorry, my goof. Both events do have the Cancel option. I must have been getting confused with UnloadMode, which is only available in QueryUnload.
