功能强大，可屏蔽绝大多数Windows快捷键，Ctrl+ALt+Delete也进行了间接屏蔽

通过vb钩子函数捕捉window消息, 记录键盘鼠标的消息和数据, 再通过回调函数播放出来

这是 Visual C++ 典型模块与项目实战大全 清华大学出版社 第11章 截屏工具（动态链接库+键盘钩子+光标捕获+类橡皮类CRectTracker） 源码，为了防止光盘丢失，特存于此。

gdi+实现截屏保存png文件，鼠标钩子，直接截图 可选定保存特定矩形区域或整个屏幕或活动窗口； 注意全局鼠标钩子的使用 gdi画线在mousemove事件里的擦除 代码不完善仅供参考，欢迎修改！

php钩子的核心类，php插件机制的实现，都 是由钩子的核心类来处理的

C#键盘鼠标钩子，可以知道键盘和鼠标的动作, 本人根据这个工具，制作成了不用鼠标键盘五分钟 用友自动退出工具 当然了，还可以做成很多程序！ QQ交流：873968102

运行后无法杀掉其进程，可屏蔽键盘。不过对360保险箱保护的进程无法嵌入。
