Hi,
Any one know how to have a window in mfc to display an avi file or web-cam preview?

I try to use a stastic text (staticScreen)in MFC like:

//-----------------in .h

IVideoWindow *m_pVideoWindow; CStatic m_staticScreen;
// also some code in dodataexchange...
//-----------------in .cpp

HWND m_ScreenhWnd = m_staticScreen.GetSafeHwnd() ;
hr=pGraphBuilder->QueryInterface(IID_IVideoWindow,(LPVOID*) m_pVideoWindow);

m_pVideoWindow->put_Visible(OAFALSE);

hr=m_pVideoWindow->put_Owner((OAHWND)m_pVideoWindow);

//m_pVideoWindow->put_Owner(NULL);

hr=m_pVideoWindow->put_WindowStyle(WS_CHILD|WS_CLIPCHILDREN);

It works when I put_owner to null or put_owner to m_hWnd
but when I put_owner to m_ScreenhWnd, I can see somthing there, but the static window will not automatically update. So I wounder if there are some events related to this static control. Or should I just looking for other control for the disable?
