Add Menu in Applicaton Based on Dialog

I use Xtreme ToolkitPro v10.3.1 to beautify the application based on dialog. After I loaded a skin, the menu disappeared. Then I write the code as follow:

    // Initialize the command bars
 if (!m_wndStatusBar.Create(this) ||
        !m_wndStatusBar.SetIndicators(indicators,
        sizeof(indicators)/sizeof(UINT)))
    {
        TRACE0("Failed to create status bar\n");
        return -1;      // fail to create
    }

 if (!InitCommandBars())
        return -1;

 CXTPCommandBars* pCommandBars = GetCommandBars();
 // Add the menu bar
 CXTPCommandBar* pMenuBar = pCommandBars->SetMenu(
  _T("Menu Bar"), IDR_MAINFRAME);
 if(pMenuBar == NULL)
 {
  TRACE0("Failed to create menu bar.\n");
  return -1;      // fail to create
 }
