    {
        public static bool WindowProc(this Control me, IntPtr hWnd, uint uMessage, IntPtr wParam, IntPtr lParam)
        {
            //  Get the wndproc function.
            try
            {

                var methodInfo = me.GetType().GetMethod("WndProc", BindingFlags.Instance | BindingFlags.NonPublic);
                return (bool)methodInfo.Invoke(me, new object[] { new Message { HWnd = hWnd, WParam = wParam, LParam = lParam, Msg = (int)uMessage } });
            }
            catch (Exception exception)
            {
