I try to play video with direct show under WinCE 5.0 OS

my problem as below:
1) my step: I first create an interface "IGraphBuilder", then query "IVideoWindow" with it, after render a file, set the IVideoWindow owner to a dialog, set its style as "WS_CHILD| WS_CLIPSIBLINGS", finally start the play.
actual result:
a) the video play window is not the child window of my pointed dialog, the video window is a seperate window (it can be seen on wince task bar)
b) when the dialog pop up and show, the Video windos is minimized.

2) my application will paint the dialog client rect on time, how can I avoid the re-paint the video window, Is there any parameters can be set for video window (like always set it to top)?

Besides, almost same code under windowXP is OK.
my mfc application is dialog based.

        hr = m_pGraph->RenderFile(str_filename,NULL);

	if(FAILED(hr))

	{

		AfxMessageBox(TEXT("can not open the fail"));

		return FALSE;

	}

 

	//////////////////////////////////////////////////////////////

	// set vidio window owner and window position

	hr = m_pVidWin->put_Owner((OAHWND) (this->GetSafeHwnd()) );

	if (SUCCEEDED(hr))

	{

		// The video window must have the WS_CHILD style

		hr = m_pVidWin->put_WindowStyle( WS_POPUP | WS_BORDER  );

		if(FAILED(hr))

		{

			AfxMessageBox(TEXT("put_WindowStyle \"WS_CHILD | WS_CLIPSIBLINGS\" fail"));

		}

		// Read coordinates of video container window

		RECT rc;

		this->GetClientRect(&rc);

		long width =  rc.right - rc.left;

		long height = rc.bottom - rc.top - 50;

 

		// Ignore the video's original size and stretch to fit bounding rectangle

		hr = m_pVidWin->SetWindowPosition(rc.left, rc.top, width, height);

		if(FAILED(hr))

		{

			AfxMessageBox(TEXT("m_pVidWin SetWindowPosition fail"));

			return FALSE;

		}

	} else 

	{

		AfxMessageBox(TEXT("put_Owner fail"));

		return FALSE;

	}

 

	// let window visible

	hr = m_pVidWin->put_Visible(OATRUE);

	if(FAILED(hr))

	{

		AfxMessageBox( _T("put_Visible: OATRUE fail"));

	}

	

	// start play !!!

	hr = m_pControl->Run();

	if(FAILED(hr))

	{

		CString errmsg;

		errmsg = _T("play video") + str_filename + _T("fail");

		AfxMessageBox( errmsg );

	}

Open in new window
