   I want to add a Formview to the CXTTabView, but it cannot show the Formview dialog. my code:
in MyAppView::OnCreate: (derived from CXTTabView)
 m_pVideoPlayView = new CVideoPlayView //;(CVideoPlayView is derived from CFormView)
if ( m_pVideoPlayView && ::IsWindow( m_pVideoPlayView->m_hWnd ) )
 {
  m_pVideoPlayView->DestroyWindow();
 }
 CCreateContext cc;
 ZeroMemory(&cc, sizeof(cc));
 m_pVideoPlayView = (CVideoPlayView*)RUNTIME_CLASS(CVideoPlayView)->CreateObj ect();
 if (!m_pVideoPlayView  || !((CWnd *)m_pVideoPlayView)->Create(
  NULL, NULL, AFX_WS_DEFAULT_VIEW, CRect(0, 0, 0, 0), this, VIDEOPLAY, &cc))
 {
  TRACE0( "Failed to create video videoplay view.\n" );
  return -1;
 }
AddView(_T("VideoPlayer"), m_pVideoPlayView);

The result of the AddView is successful, but when i run my app, i cannot see the dialog in the revalant page. did i loss some initializations?

	One, you have a memroy leak. You new the CVideoPlayerView, and then override the pointer with CreateObject!!!! new or CreateObject, One or the other not both. Have you tried giving your view a size when you create it. Or maybe consider using the alternate AddView AddView(_T("VideoPlayer"),RUNTIMECLASS(CVideoPlayerView)); m_pVideoplay = (CVideoPlayerView *)GetView(0); Ali
