使用visual studio 2019 创建过程请参考Bili的上一篇文章⬇⬇

→！使用visual studio 2019 创建简单的MFC窗口「使用底层的C语言」

划重点：项目->属性->常规->高级->将MFC的使用设置为在“共享dll中使用mfc”

学的不仅仅是技术，更是梦想

头文件mfc.h#include <afxwin.h>	//mfc头文件class MyApp:public CWinApp{public:virtual BOOL InitInstance();};class MyFrame :public CFrameWnd {	//窗口框架类public:MyFrame();//声明宏 提示消息映射机制DECLARE_MESSAGE_MAP();afx_msg void OnLButtonDown(UINT,CPoint);afx_msg void OnChar(UINT,UINT,UINT);afx_msg void OnPaint();};
