消息处理函数问题？

[5312]

我看一程序时候，它的对话框程序中有WM_QUERYENDSESSION，我用我的CLASSWIZARD里面没有？
怎么才可以把不常用的处理消息添加进去？
谢谢！

用ClassWizzard添加一个消息映射，然后按修改的地方，医葫芦画瓢，自己改。

不是的。好像自己就带了。我看了他们的那CLASSWIZARD，里面的消息确实比我的多的多。

自己加吧
一样的

[smartstar2005]

一样的啊,
消息函数自己定义也一样。

[zxw2844]

好多消息是要自己加上去的,怎么加???
......在ClassView窗口,在具体某个类上单击鼠标右键,有个Add Windows Message Handler...
并不是所有的类都这一项,要看类的类型.
