【摘要】 Windows消息在系统及应用程序的运行中起着关键的作用,每一次键盘、鼠标的点击都会有消息的传递,应用程序通过对消息的响应来实现与用户的交互。钩子(Hook)函数作为Windows编程中的一种强有力的工具,可以有效地截获Windows系统内部传递的消息,在消息到达目标窗口的处理函数之前先对消息做出相应处理,从而实现对应用程序的监视与控制。文中描述了Windows消息的构成,介绍了Hook函数的安装、释放及类型,最后介绍了一个Hook函数实现应用程序操作的捕捉的实例。更多还原

【Abstract】 Windows message plays a key role in the operation of system and application. Every click on the keyboard and mouse will transfer a message. Application can interact with user by responding to the message. As a powerful tool in Windows programming, Hook can effectively intercept the internal message transferred by Windows system. Before the message reaches the functional processing of the target window, Hook can have already dealt with it, and implement the control and monitoring of application. This article describes the structure of Windows message in detail, and introduces how to install or remove the Hook and the types of Hook in system. Finally, it gives an example of Hook function capturing the operation of application.更多还原
