[解决办法]
CHotelMainMenuWnd 有没有继承 CWnd ？？
清理工程重新编译。。
[解决办法]
'CHotelMainMenuWnd::messageMap' 这是你自定义函数？实现了每一天？？
[解决办法]
你工程建的对不对，系统生成的宏你是否有改动
[解决办法]
BEGIN_MESSAGE_MAP 这段代码发上来。。。
------解决方案--------------------

BEGIN_MESSAGE_MAP 这段代码发上来。
[解决办法]
.h中的DECLARE_MESSAGE_MAP()
.cpp中的BEGIN_MESSAGE_MAP()/END_MESSAGE_MAP()是否存在？
