VC++自定义键盘指定键的功能，实例中定义“M”键为热键，相当于按下ESC键，程序退出，并且好像鼠标不能拖动对象了。当然也可以定义任意键在软件中的特定功能，比如定义一些组合键或快捷键之类的，为你程序增加快捷键的时候可参考本源码进行。-VC++ custom keyboard key functions specified, the instance is defined " M"　key as a hot key, the equivalent of pressing the ESC key, the program quits, and the mouse can not seem to drag the object. Of course, any key can also be defined in the software-specific functions, such as defining some combination of keys or shortcut keys and the like, for you to add shortcuts when the program can be carried out with reference to the source.
