等待下班放假之hook学习

三个星期了，真TMD的快。
昨天李鹏让我做个类似外挂的按键工具，查下资料，很难看懂的饿。
以为调用API函数就可以解决问题，貌似不可以诶。网络上查了点资料，很多饿，貌似又和钩子（hook)有关系了。
又是一个心技术，得学啊。看了半天找了点资料看着，貌似不怎么懂的饿。记得上个星期自己疯狂的复习以前基础的内容，才算了解了事件的处理机制。看来这个星期日有得忙了。
慢慢看吧虽然上面写的是hook学习，但是貌似自己还不怎么懂，基本就没有怎么学的饿。上网查了下看到这个代码，貌似和自己要的有点关系。

[DllImport("user32.dll")]
        static extern bool SetCursorPos(int X, int Y);

        [DllImport("user32.dll")]
        static extern void mouse_event(MouseEventFlag flags, int dx, int dy, uint data, UIntPtr extraInfo);

        [DllImport("user32.dll")]
        static extern IntPtr FindWindow(string strClass, string strWindow);

        [DllImport("user32.dll")]
        static extern IntPtr FindWindowEx(HandleRef hwndParent, HandleRef hwndChildAfter, string strClass, string strWindow);

        [DllImport("user32.dll")]
        static extern bool GetWindowRect(HandleRef hwnd, out NativeRECT rect);

        [DllImport("user32.dll", EntryPoint = "GetCursorPos")]
        static extern int GetCursorPos();

基本当没看到。搞了半天还是不知道那个user32.dll文件是怎么来的。管它呢先看着吧。好像是调用winform的api函数来着，说只有调用它进行非托管才可以运行的呢。吊得了。不知道连操作系统里面到底有什么都不知道。
看着这个程序更是一头雾水。
先把代码弄上来。免得以后找也找不到的饿。
