Preventing a form form closing

When a form is being closed, either through alt-f4 or the controlbox, the formclosing event is fired. At this point, you can take additional action, or prevent the form from closing alltogether.

    Private Sub form_BestellingenEditor_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing

        e.Cancel = True

    End Sub
