Context menu

I want to show main application menu as context menu. Consider SDI Doc-View application created by MFC Application Wizard. I add the following function to it:

void CMenuTestView::OnContextMenu(CWnd* pWnd, CPoint point)
{
    CMenu menu;
    menu.LoadMenu(IDR_MAINFRAME);

    menu.TrackPopupMenu(TPM_RIGHTBUTTON | TPM_LEFTALIGN, point.x, point.y, AfxGetMainWnd());
}

It shows the context menu, but first menu level (File, View, Edit ...) is shown without text. How can I change this code to get right result ? Menu resource should not be changed, only code. Thanks.

  CMenu menuMain;
   menuMain.LoadMenu(IDR_MAINFRAME);
   CString s;
   menuMain.GetMenuString(0, s, MF_BYPOSITION);


   CMenu menu;
   menu.CreatePopupMenu();
   menu.AppendMenu(MF_STRING, 12345, (LPCTSTR)s);


    menu.TrackPopupMenu(TPM_RIGHTBUTTON | TPM_LEFTALIGN, point.x, point.y, AfxGetMainWnd());


I think you will need to load the main menu and copy the contents to a new menu item by item

Maybe, but this code cannot be used as prototype. File is added as menu item and not as popup menu. I still need full solution.

This is some more

      CMenu menuMain;
      menuMain.LoadMenu(IDR_MAINFRAME);
      CString s;
      UINT nID;


      CMenu menu;
      CMenu subMenu;
      menu.CreatePopupMenu();

      menuMain.GetMenuString(0, s, MF_BYPOSITION);
      nID = menuMain.GetMenuItemID(0);
      if(nID == -1)
      {
            CMenu* pPopup = menuMain.GetSubMenu(0);

            subMenu.CreateMenu();
            
            menu.AppendMenu(MF_POPUP, (UINT)subMenu.GetSafeHmenu(), (LPCTSTR)s);


            pPopup->GetMenuString(0, s, MF_BYPOSITION);
            nID = pPopup->GetMenuItemID(0);
            subMenu.AppendMenu(MF_STRING, nID, (LPCTSTR)s);
      }
      else
            menu.AppendMenu(MF_STRING, nID, (LPCTSTR)s);


      menu.TrackPopupMenu(TPM_RIGHTBUTTON | TPM_LEFTALIGN, point.x, point.y, AfxGetMainWnd());



You will need some recursive routine and obviously need to create menus with the new keyword.  It will also require more work to cope with separators, check marks etc.

A bit more to demonstrate the principle

   CMenu menuMain;
   menuMain.LoadMenu(IDR_MAINFRAME);
   CString s;
   UINT nID;


      CMenu menu;
      CMenu subMenu;
      CMenu subMenu2;
      menu.CreatePopupMenu();

      menuMain.GetMenuString(0, s, MF_BYPOSITION);
      nID = menuMain.GetMenuItemID(0);
      if(nID == -1)
      {
            CMenu* pPopup = menuMain.GetSubMenu(0);

            subMenu.CreateMenu();
            
            menu.AppendMenu(MF_POPUP, (UINT)subMenu.GetSafeHmenu(), (LPCTSTR)s);


            pPopup->GetMenuString(0, s, MF_BYPOSITION);
            nID = pPopup->GetMenuItemID(0);
            subMenu.AppendMenu(MF_STRING, nID, (LPCTSTR)s);

            pPopup->GetMenuString(1, s, MF_BYPOSITION);
            nID = pPopup->GetMenuItemID(1);
            subMenu.AppendMenu(MF_STRING, nID, (LPCTSTR)s);
      }
      else
            menu.AppendMenu(MF_STRING, nID, (LPCTSTR)s);


      menuMain.GetMenuString(1, s, MF_BYPOSITION);
      nID = menuMain.GetMenuItemID(1);
      if(nID == -1)
      {
            CMenu* pPopup = menuMain.GetSubMenu(1);

            subMenu2.CreateMenu();
            
            menu.AppendMenu(MF_POPUP, (UINT)subMenu2.GetSafeHmenu(), (LPCTSTR)s);


            pPopup->GetMenuString(0, s, MF_BYPOSITION);
            nID = pPopup->GetMenuItemID(0);
            subMenu2.AppendMenu(MF_STRING, nID, (LPCTSTR)s);

            pPopup->GetMenuString(1, s, MF_BYPOSITION);
            nID = pPopup->GetMenuItemID(1);
            subMenu2.AppendMenu(MF_STRING, nID, (LPCTSTR)s);
      }
      else
            menu.AppendMenu(MF_STRING, nID, (LPCTSTR)s);


    menu.TrackPopupMenu(TPM_RIGHTBUTTON | TPM_LEFTALIGN, point.x, point.y, AfxGetMainWnd());
