Example of CWnd window frame in C++

The example of this article about the CWnd window frame, to share with you for your reference. Specific analysis is as follows:

. H header file code is as follows:

#include <afxwin.h>  

  

class CMyApp:public CWinApp  

{  

public:  

    virtual BOOL InitInstance();  

};  

  

//CMainWindow  

class CMainWindow:public CWnd  

{  

public:  

    CMainWindow();  

    ~CMainWindow();  

  

protected:  

    afx_msg void OnNcDestroy( );  

    afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);  

    afx_msg void OnDestroy( );  

    DECLARE_MESSAGE_MAP()  

};

. CPP source file code is as follows:

#include "ReadBMP.h"  

#include "resource.h"  

  

CMyApp theApp;  

BOOL CMyApp::InitInstance()  

{  

    m_pMainWnd = new CMainWindow;  

    m_pMainWnd->ShowWindow(m_nCmdShow);  

    return TRUE; //You must return TRUE, or you will not enter the message loop and the interface will simply exit & NBSP; < br / >
}  

  

//CMainWindow  

BEGIN_MESSAGE_MAP(CMainWindow, CWnd)  

ON_WM_CREATE()  

END_MESSAGE_MAP()  

//Constructor & NBSP; < br / >
CMainWindow::CMainWindow()  

{  

    LPCTSTR lpszClassName = ::AfxRegisterWndClass(CS_HREDRAW|CS_VREDRAW, ::LoadCursorA(NULL, IDC_ARROW), (HBRUSH)(COLOR_3DFACE+1), theApp.LoadIcon(IDI_MAIN));  

    CreateEx(WS_EX_CLIENTEDGE, lpszClassName, "xxx", WS_OVERLAPPEDWINDOW, CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,CW_USEDEFAULT,NULL,NULL);  

}  

//Destructor & NBSP; < br / >
CMainWindow::~CMainWindow()  

{  

  

}  

//Message mapping function & NBSP; < br / >
int CMainWindow::OnCreate(LPCREATESTRUCT lpCreateStruct)  

{  

    //OutputDebugString("oncreate");  

    //Setup menu & menu; < br / >
    HMENU hMenu = ::LoadMenuA(theApp.m_hInstance, (LPCSTR)IDR_MENU);  

    ::SetMenu(m_hWnd, hMenu);  

    return 0;  

}  

  

void CMainWindow::OnNcDestroy( )  

{  

    delete this;  

}  

void CMainWindow::OnDestroy()  

{  

      

}

Hope that the article described in the C++ programming to help you.
