Question

Before the user closes the form I want to prompt with a confirmation box.

I am not sure how to do this.
I have tried the code below and it prompts the user but upon clicking no it closes the form anyway:

Private Sub Form_Close()
    If MsgBox("Test", vbYesNo + vbExclamation, "Confirm close") = vbYes Then
    Else
        Cancel = True
    End If
End Sub

Answer 1

You can’t cancel the close event but you can cancel the unload event

Private Sub Form_Unload(Cancel As Integer)

    If MsgBox("Test", vbYesNo + vbExclamation, "Confirm close") <> vbYes Then
         Cancel = True
    End If

End Sub
