C++ & MFC Practice

MFC 應用程式

建立應用程式類別

1.繼承CWinApp
2.直接使用CFrameWnd 類別產生視窗

專案設定:

MFC的使用 : 使用MFC靜態程式庫
字元集:使用多位元組字元集
#include

class MyApp: public CWinApp
{
public :
BOOL InitInstance()
{
CFrameWnd *Frame = new CFrameWnd();
m_pMainWnd = Frame;

Frame->Create(NULL,"Hello MFC");
Frame->ShowWindow(SW_SHOW);
return true;
}
};
MyApp a_app; //Build Application
