我在ms的group上问了个问题
http://msdn.microsoft.com/newsgroups/default.aspx?dg=microsoft.public.vc.mfc&tid=402a414c-a125-45bd-9cf4-c1819db7e3e4：
in http://msdn2.microsoft.com/en-us/library/480b7kf7.aspx, it says that
pGdiObject->DeleteTempMap(); // Causes compiler error
But I'm confused for a static member can be called by the object or a pointer.
Is there anything wrong of my understanding?
回答的人到蛮多，讨论的也很热烈，但都没有直接回答我的问题，我的问题是，对于静态函数，
pGdiObject->DeleteTempMap()
; // Causes compiler error，
到底对不对？如果不对，就是msdn错了，不过总觉得比较奇怪，msdn不该出这样的错的
