|zyciis| 我在CSDN上面下载的一个HOOK程序但没有效果　大家看看哪里出错了　谢谢大家　

http://d.download.csdn.net/down/258027/spring21st        public void Hook_Start()
        {
            // 安装键盘钩子
            if (hHook == 0)
            {
                KeyBoardHookProcedure = new HookProc(KeyBoardHookProc);
                hHook = SetWindowsHookEx(WH_KEYBOARD_LL,
                            KeyBoardHookProcedure,
                            Marshal.GetHINSTANCE(Assembly.GetExecutingAssembly().GetModules()[0]), 0);
                //如果设置钩子失败.
                if (hHook == 0)
                {
                    Hook_Clear();
                    throw new Exception("设置Hook失败!");
                }
            }
        }在这里面的SetWindowsHookEx事件总是为０也就是说设置失败
到低哪里出错了呢
麻烦大家下下那个代码看看谢谢
