MFC环境下的消息映射，其原理和我们讲解过的Win32下的消息映射是类似的。简单地讲，就是让程序员指定要某个MFC类（有消息处理能力的类）处理某个消息。MFC提供了工具 ClassWizard来帮助实现消息映射，在处理消息的类中添加一些有关消息映射的内容和处理消息的成员函数。程序员负责编写消息处理函数的代码，实现所希望的功能。-MFC environment news mapping, its principle and we explain the news of the Win32 mapping is similar. Simply speaking, is to make the programmer to a designated MFC class (a message processing power of the classes) handling one of news. MFC provides tools ClassWizard to help realize the message map, in dealing with news of the class to add some relevant news content and processing of mapping news member function. Programmers responsible for writing the handler code, to achieve the function of hope.
