我是一个初学VC的莱鸟,以下是一个CMFCView类的声明,看不太懂,麻烦那位高手逐句注释一下!
谢谢先!!// MFCView.h : interface of the CMFCView class

上面这两句什么意思,虑函数一定要加到它们之间吗 //{{AFX_MSG(CMFCView)
// NOTE - the ClassWizard will add and remove member functions here.
// DO NOT EDIT what you see in these blocks of generated code !
//}}AFX_MSG
上面四句又是什么意思,那些加到它们之间,那些加到它们外面0 DECLARE_MESSAGE_MAP()
上面这一句又是什么意思谢谢先!
