MCI commands

[fwehlin]

Hi,

I hope someone can help me out with som MCI-programming. I have made a small app that is going to play a mpegmovie using mci-commands. The problem I have is that I wont get it to play in the dialog I have created for it. How can I do this. I have tried to pass in the handle for dialog but that wont do it. Any suggestions?

Here´s the code for it so far, one function too open the device, one to load the file and one to play the file.



[
BOOL CDigitalVideo::Open(HWND hWnd)
{

if( m_bOpened )
return( TRUE );

m_bPaused = m_bPlaying = FALSE;
m_wDeviceID = 0;

MCI_DGV_OPEN_PARMS OpenParms;
OpenParms.lpstrDeviceType = "mpegvideo";
OpenParms.wDeviceID = 0;
OpenParms.hWndParent = hWnd; //
OpenParms.dwStyle = WS_CHILD | WS_CLIPCHILDREN | WS_CLIPSIBLINGS;

if( mciSendCommand( 0, MCI_OPEN, MCI_OPEN_TYPE |MCI_DGV_OPEN_PARENT|
MCI_DGV_OPEN_WS | MCI_WAIT ,(DWORD)(LPVOID) &OpenParms ) )
return( FALSE );

m_wDeviceID = OpenParms.wDeviceID;
m_bOpened = TRUE;

MCI_DGV_SET_PARMS SetParms;
SetParms.dwTimeFormat = MCI_FORMAT_MSF;
//SetParms.dwFileFormat = MCI_DGV_FF_MPEG;

if( mciSendCommand( m_wDeviceID, MCI_SET, MCI_SET_TIME_FORMAT /*|
MCI_DGV_SET_FILEFORMAT */| MCI_WAIT,
(DWORD)(LPVOID) &SetParms ) )
{
Close ();
return( FALSE );
}

return( TRUE );

}

BOOL CDigitalVideo::LoadFile(LPSTR lpstrFileName/*, HWND hWnd*/)
{
if(!m_bOpened)
return( FALSE );

MCI_DGV_LOAD_PARMS LoadParms;
LoadParms.lpfilename = (LPSTR)lpstrFileName;

if(mciSendCommand(m_wDeviceID, MCI_LOAD, MCI_LOAD_FILE,
(DWORD)(LPVOID) &LoadParms ))
return( FALSE );

return (TRUE);
}

BOOL CDigitalVideo::Play (HWND hWnd)
{

if( !Open(hWnd) )
return( FALSE );

MCI_DGV_PLAY_PARMS PlayParms;

PlayParms.dwFrom = MCI_MAKE_MSF( GetMinutes(), GetSeconds(), GetFrames());

if( mciSendCommand( m_wDeviceID, MCI_PLAY, MCI_FROM ,
(DWORD)(LPVOID) &PlayParms ) )
return( FALSE );

m_bPaused = FALSE;
m_bPlaying = TRUE;

return( TRUE );

}
]
