C#窗口攔截鍵盤事件

有時候需要攔截鍵盤的事件使程序按照設計者的要求執行。

        protected override void WndProc(ref Message m)
        {
            const int WM_HOTKEY = 0x0312; // 熱鍵消息
            if (m.Msg == WM_HOTKEY)
            {
                //最大最小化熱鍵

            }

            // 鼠標左鍵右鍵中間滑輪事件時，屏保計時器清零 [9/15/2010 huzhonghua]
            const int WM_LBUTTONDOWN = 0x0201;
            const int WM_RBUTTONDOWN = 0x0204;
            const int WM_MOUSEDOWN = 0x0210;
            const int WM_MOUSEWHEEL = 0x020A;
            if (m.Msg == WM_MOUSEDOWN || m.Msg == WM_LBUTTONDOWN || m.Msg == WM_RBUTTONDOWN || m.Msg == WM_MOUSEWHEEL)
            {
               //所有鍵盤事件

            }
            base.WndProc(ref  m);
        }
