删除顶级菜单项（在MFC中）。。

1＆gt;我可以使用以下代码删除MFC MDI应用程序中的顶级菜单项（以及其子菜单）。

void CMainFrame::OnRemoveMyMenu()
{
    ////////////////////////////////////////////////////////////////////////
    CString sMenuText = _T("");
    BOOL bReturn = FALSE;

    const CMFCMenuBar *pMenuBar = GetMenuBar();

    HMENU hMainMenu = NULL;
    HMENU hSubMenu = NULL;

    hMainMenu = pMenuBar->GetHMenu();
    ASSERT(hMainMenu);

    RemoveMenu(hMainMenu, 3, MF_BYPOSITION);
    //----------------------------------------------------------------------
}

2＆gt;但是，它仅在AppWizard创建 idr_mainframe 菜单上工作。它确实在AppWizard在资源中创建的另一个菜单上确实可以使用，主要是 idr_＆gt; type 菜单（这是使用MDI窗口显示的菜单）。

3＆gt;我尝试在视图中的不同位置调用类似的代码，并从视图中调用与上述相同的代码。但这无效。

4＆gt;有人可以暗示我缺少什么吗？

非常感谢

1> I could remove top level menu item (along with its sub-menus) in MFC MDI application using below code.

void CMainFrame::OnRemoveMyMenu()
{
    ////////////////////////////////////////////////////////////////////////
    CString sMenuText = _T("");
    BOOL bReturn = FALSE;

    const CMFCMenuBar *pMenuBar = GetMenuBar();

    HMENU hSubMenu = NULL;

    hMainMenu = pMenuBar->GetHMenu();
    ASSERT(hMainMenu);

    RemoveMenu(hMainMenu, 3, MF_BYPOSITION);
    //----------------------------------------------------------------------
}

2> However, it works only on AppWizard created IDR_MAINFRAME menu. It does "not" work on another menu created in Resources by AppWizard, mainly IDR_<>TYPE menu (which is the Menu displayed with MDI window is put on).

3> I tried to call similar code within different places in View as well as call the same code as above, placed in MainFrame from View. But it did not work.

4> Can somebody given hint as to what I am missing?

Thanks a lot
