關於winform 屏蔽FLASH界面鼠標右鍵的問題

最近測試提出問題，要求屏蔽FLASH界面的鼠標右鍵，經過驗證以下方法可行：

在文件裏添加以下代碼：

private const int GWL_WNDPROC = -4;
        public delegate IntPtr FlaWndProc(IntPtr hWnd, int msg, IntPtr wParam, IntPtr lParam);

        private IntPtr OldWndProc = IntPtr.Zero;
        private FlaWndProc Wpr = null;

        [DllImport("user32.dll", CharSet = CharSet.Auto)]
        public static extern IntPtr SetWindowLong(IntPtr hWnd, int nIndex, FlaWndProc wndProc);
        [DllImport("user32.dll", CharSet = CharSet.Auto)]
        public static extern IntPtr CallWindowProc(IntPtr wndProc, IntPtr hWnd, int msg, IntPtr wParam, IntPtr lParam);

        private IntPtr FlashWndProc(IntPtr hWnd, int msg, IntPtr wParam, IntPtr lParam)
        {
            if (msg == 516)
                return (IntPtr)0;
            return CallWindowProc(OldWndProc, hWnd, msg, wParam, lParam);
        }

在load函數裏添加：

           this.Wpr = new FlaWndProc(this.FlashWndProc);
            this.OldWndProc = SetWindowLong(axShockwaveFlash1.Handle, GWL_WNDPROC, Wpr);
