求助：请问分别用什么代码是屏蔽鼠标，热键或者屏蔽键盘呀？？？

Question

最简单的就是 
override void WndProc(ref Message m)底层的就是hook了

Answer 1

简单的热键WndProc就足够了类似Ctrl+Alt+Delete比较复杂

//有关鼠标和键盘钩子的相关定义
        static int hhookMouse = 0;
        static int hhookKeyBoard = 0;
        public const int WH_MOUSE = 14;
        public const int WH_KEYBOARD = 2 ;
        public const int HC_ACTION = 0;
        public delegate int HookProc(int nCode, IntPtr wParam, IntPtr iParam);
        HookProc MouseHookProcedure, KeyBoardHookProcedure;
        [DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
        public static extern int SetWindowsHookEx(int idHook,HookProc lpfn,IntPtr hinstance,int threadid);
        [DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
        public static extern int CallNextHookEx(int idHook, int nCode, IntPtr wParam, int lParam);
        [DllImport("user32.dll", CharSet = CharSet.Auto, CallingConvention = CallingConvention.StdCall)]
        public static extern bool UnhookWindowsHookEx(int idHook);     
/// <summary>
        /// 钩子处理方法（键盘锁定）
        /// </summary>
        /// <param name="nCode"></param>
        /// <param name="wParam"></param>
        /// <param name="lParam"></param>
        /// <returns></returns>
        private int KeyBoardHookProc(int nCode, IntPtr wParam, IntPtr lParam)
        {
            //如果nCode<0，直接调用CallNextHookEx返回
            if (nCode < 0)
                //return CallNextHookEx(hhookKeyBoard, nCode, wParam, lParam);
                return 1;
            //函数将消息向下传递，下一个钩子处理将截获这一消息
            //if (nCode != HC_ACTION)
                //return CallNextHookEx(hhookKeyBoard, nCode, wParam, lParam);
            return 1;
        }
        /// <summary>
        /// 启动键盘锁定
        /// </summary>
        /// <returns></returns>
        private bool EnableKeyBoardCapture()
        {
            KeyBoardHookProcedure = new HookProc(this.KeyBoardHookProc);
            Process currentProcess = Process.GetCurrentProcess();
            //安装全局键盘钩子
            hhookKeyBoard = SetWindowsHookEx(WH_KEYBOARD, KeyBoardHookProcedure, currentProcess.MainModule.BaseAddress, 0);
            if (hhookKeyBoard == 0)
                return false;
            return true;
        }
        /// <summary>
        /// 解除键盘锁定
        /// </summary>
        /// <returns></returns>
        private bool DisableKeyBoardCapture()
        {
            return UnhookWindowsHookEx(hhookKeyBoard);
        }看看这个有没有用吧

Answer 3

1.将窗体的属性KeyPrieview设置为true
2.在窗体KeyDown事件中加如下代码
private void Form1_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
//屏掉alt+f4
if (e.KeyCode == Keys.F4&&e.Alt)
{
e.Handled = true;
}}
