C#窗口拦截键盘事件

有时候需要拦截键盘的事件使程序按照设计者的要求执行。

protected override void WndProc(ref Message m) { const int WM_HOTKEY = 0x0312; // 热键消息 if (m.Msg == WM_HOTKEY) { //最大最小化热键 } //鼠标左键右键中间滑轮事件时，屏保计时器清零 [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) { //所有键盘事件 } base.WndProc(ref m); }
