Question

In a vb.net windows application, I need user to confirm before closing application. I have this code in FormClosing event

If BackgroundWorker1.IsBusy Then
    Dim UserSelection As Integer = MsgBox("Do you want Cancel Processing and Exit Application?", MsgBoxStyle.Exclamation + MsgBoxStyle.YesNo, "Exit Application")
    If UserSelection = 6 Then
        BackgroundWorker1.CancelAsync()
        e.Cancel = True
    Else
        ????
    End If
End If

How can I cancel form closing if user clicked No?

Tried e.Cancel = false but it didn’t work (exits application).

Answer 1

e.Cancel = True would stop the form closing.
