Hello.


I want to add a menu dynamically.

Even if, after LoadFrame, I add a menu

It is not displayed.

Please teach a method to add dynamically.



    CMainFrame* pFrame = new CMainFrame;
 m_pMainWnd = pFrame;
 if( ! pFrame->LoadFrame(
   IDR_MAINFRAME,
//   IDR_NXBKTYPE,
   WS_OVERLAPPEDWINDOW|FWS_ADDTOTITLE,
   NULL,
   NULL
   )
  )
  return FALSE;
 // window placement persistence
		 :
		 :
		 :

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
 if( CExtNCW < CFrameWnd > :: OnCreate( lpCreateStruct ) == -1 )
  return -1;
 // メニューバーの作成
 if( ! m_wndMenuBar.Create(
   NULL,
   this,
   ID_VIEW_MENUBAR
   )
  )
 {
  TRACE0("Failed to create menubar\n");
  return -1;
 }
    m_wndMenuBar.InitMenuMCB();
		 :
		 :
		 :

void CNxbkMenuControlBar::InitMenuMCB()
{
 CMenu popupMenu;
 BOOL bCreate;
 bCreate = popupMenu.CreatePopupMenu ();
 // メインメニュー
 bCreate = popupMenu.AppendMenu ( MF_STRING, 123 , "aaa" );
 bCreate = popupMenu.AppendMenu ( MFT_SEPARATOR  );
 bCreate = popupMenu.AppendMenu ( MF_STRING, 444 , "bbbb" );
 bCreate = popupMenu.AppendMenu ( MFT_SEPARATOR  );
 CMenu* pMenu = GetMenu();
 bCreate = pMenu->AppendMenu ( MF_POPUP, ( UINT ) popupMenu.Detach() , "AddMenu" );
}

Thank you for the test project. The approach you are using in your app works only in the SDI environment. The MDI environment changes menus on-the-fly. Your code is almost OK. You only forgot to re-build menu bar buttons from the changed menu:

void CNxbkMenuControlBar::InitMenuMCB()
{
CMenu popupMenu;
            BOOL bCreate;
            bCreate = popupMenu.CreatePopupMenu ();
            bCreate = popupMenu.AppendMenu ( MF_STRING, 123 , "aaa" );
            bCreate = popupMenu.AppendMenu ( MFT_SEPARATOR  );
            bCreate = popupMenu.AppendMenu ( MF_STRING, 444 , "bbbb" );
            bCreate = popupMenu.AppendMenu ( MFT_SEPARATOR  );
CMenu* pMenu = GetMenu();
            bCreate = pMenu->AppendMenu ( MF_POPUP, ( UINT ) popupMenu.Detach() , "_POPUP_" );
            UpdateMenuBar( FALSE ); // THIS LINE IS IMPORTANT
}

Could you send the complete source code for CMainFrame and CNxbkMenuControlBar classes to the support mail box at this web site?
