asp.net two ways to remove the MFC single document default menu bar

There are two ways:

Method 1: overloading the Create function of the framework class. The code is as follows:

 
BOOL CMainFrame::Create(LPCTSTR lpszClassName, LPCTSTR lpszWindowName, DWORD dwStyle , const RECT& rect , CWnd* pParentWnd , LPCTSTR lpszMenuName , DWORD dwExStyle , CCreateContext* pContext) 
{ 
    // TODO:  Add dedicated code and here / Or call the base class  
//    return CFrameWnd::Create(lpszClassName, lpszWindowName, dwStyle, rect, // //pParentWnd, lpszMenuName, dwExStyle, pContext); 
HMENU nIDorHMenu = NULL; 
     return CFrameWnd::CreateEx(dwExStyle,lpszClassName,lpszWindowName,dwStyle, 
         rect.left,rect.top,rect.right-rect.left,rect.bottom-rect.top, 
         pParentWnd->GetSafeHwnd(), 
         nIDorHMenu, 
         (LPVOID)pContext); 
} 

Option 2: manually delete all menu items. To be specific, first define a function to delete all menu items:

 
/*! 
* \brief  Delete all menu bars.  
* 
*  Delete all menu bars from the window.  
* \return  No.  
*/ 
static void DelAllMenu(HMENU hMenu) 
{ 
    //  First remove the redundant menu items  
    int Menucount = GetMenuItemCount(hMenu); 
    for (int i = Menucount-1;i>-1;i--) 
    { 
        ::DeleteMenu(hMenu,i, MF_BYPOSITION); 
    } 
} 

Then call this function in the OnCreate function of the framework class, as follows:

 
int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) 
{ 
    if (CFrameWnd::OnCreate(lpCreateStruct) == -1) 
        return -1; 

    if (!m_wndToolBar.CreateEx(this, TBSTYLE_FLAT, WS_CHILD | WS_VISIBLE | CBRS_TOP 
        | CBRS_GRIPPER | CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC) || 
        !m_wndToolBar.LoadToolBar(IDR_MAINFRAME)) 
    { 
        TRACE0(" Could not create toolbar \n"); 
        return -1; //  Failed to create  
    } 
    if (!m_wndStatusBar.Create(this) || 
        !m_wndStatusBar.SetIndicators(indicators, 
         sizeof(indicators)/sizeof(UINT))) 
    { 
        TRACE0(" Failed to create status bar \n"); 
        return -1; //  Failed to create  
    } 
    // TODO:  Delete this if you do not need the toolbar to dock 3 line  
    m_wndToolBar.EnableDocking(CBRS_ALIGN_ANY); 
    EnableDocking(CBRS_ALIGN_ANY); 
    DockControlBar(&m_wndToolBar); 
    //  Gets the menu handle to the window  
    CMenu *pMenu = GetMenu(); 
    if (NULL!=pMenu) 
    { 
DelAllMenu(pMenu->GetSafeHmenu()); 
    } 
    return 0; 
}
