看到您编写的winx, 我有一个问题请教, 为什么MFC的消息映射要提供_AFXDLL和非_AFXDLL两个implementation, 比如
#ifdef _AFXDLL
#define DECLARE_MESSAGE_MAP() private: static const AFX_MSGMAP_ENTRY _messageEntries[]; protected: static AFX_DATA const AFX_MSGMAP messageMap; static const AFX_MSGMAP* PASCAL _GetBaseMessageMap(); virtual const AFX_MSGMAP* GetMessageMap() const;
#else
#define DECLARE_MESSAGE_MAP() private: static const AFX_MSGMAP_ENTRY _messageEntries[]; protected: static AFX_DATA const AFX_MSGMAP messageMap; virtual const AFX_MSGMAP* GetMessageMap() const; #endif
为什么直接用非_AFXDLL的版本的不行? 非要用一个函数_GetBaseMessageMap()去取基类的messageMap?

所以,有关架构之美,必然会随着整个行业,以及老许的个人积累,常讲常新了…
