如何获取到cmd.exe中的消息

Q:请问如何获取到cmd.exe中的消息？比如点击鼠标右键弹出菜单的消息，我用spy++无法获取到cmd窗口，请高手帮忙谢谢

A:

DOS程序通过一个名为Winoldap的控制台程序来运行，而这个程序则是在32位Windows控制台窗口中运行。原理上，Winoldap利用x86的"Virtual86"模式来虚拟实模式。
创建控制台时，操作系统自动创建三个"标准"文件句柄。在高级控制台编程中，用两个API函数控制这些句柄

GetStdHandle和SetStdHandle

控制台使用的不是我们常见的Win32消息队列，而是事件队列。
事件队列和Windows消息队列差不多，不过是接收输入事件，而非消息。所以Spy++当然得不到消息

ReadConsoleInput可以用来获得控制台的输入，参考

MSDN给出了一个创建标准信息队列的例子

我就花点事件给你解释下
WINDOW_BUFFER_SIZE_EVENT 屏幕大小改变时发出
MENU_EVENT 用户使用控制台菜单或工具栏时发出
FOCUS_EVENT 控制台得到输入焦点时发出


这是内部实现，当然我们外部也可以获得。利用管道，然后GetStdHandle(STD_INPUT_HANDLE);

然后即可读取Console窗口的事件。

好久没见到这么值得我回，详细解释的帖子。希望对后面看帖的朋友有帮助
