我的第一个MFC程序

 又是少打了一句话，开始我还以为是VS2008的问题#include<afxwin.h> class CHelloApp:public CWinApp { public: virtual BOOL InitInstance(); }; CHelloApp theApp; class CMainFrame:public CFrameWnd { public: CMainFrame() { Create(NULL,"啊，C++",WS_OVERLAPPEDWINDOW,CRect(0,0,400,300)); } protected: afx_msg void OnLButtonDown(UINT nFlags,CPoint point); DECLARE_MESSAGE_MAP() }; BEGIN_MESSAGE_MAP(CMainFrame,CFrameWnd) ON_WM_LBUTTONDOWN() END_MESSAGE_MAP() void CMainFrame::OnLButtonDown(UINT nFlags, CPoint point) { MessageBox("春天在哪里啊~~春天在哪里","樱花开啊 樱花开",0); CFrameWnd::OnLButtonDown(nFlags,point); } BOOL CHelloApp::InitInstance() { m_pMainWnd=new CMainFrame(); m_pMainWnd->ShowWindow(m_nCmdShow); m_pMainWnd->UpdateWindow(); return TRUE; }
