MFC 寫了一個Hello MFC

寫程序的，第一個程序，必定是 Hello World 之類的

把代碼貼出來

Hello.h

class CMyApp : public CWinApp
{
public:
	virtual BOOL InitInstance ();
};

class CMainWindow : public CFrameWnd
{
public:
	CMainWindow ();

protected:
	afx_msg void OnPaint ();
	DECLARE_MESSAGE_MAP ()
};

Hello.cpp

#include <afxwin.h>
#include "Hello.h"

CMyApp myApp;

/////////////////////////////////////////////////////////////////////////
