I have an MP3 file that is running but how do I stop the MP3 file in midstream so that I can play a different MP3 file? I am using this code to run the MP3 "IMediaControl *pMediaControl; IMediaEvent *pEvent; pGraph->QueryInterface(IID_IMediaControl, (void **)&pMediaControl); pGraph->QueryInterface(IID_IMediaEvent, (void **)&pEvent); pGraph->RenderFile(L"C:\\Song1.mp3", NULL); pMediaControl->Run();" Now I would like the gamer to press a button on the keyboard and stop the MP3 from playing without ending my application. If I type in this code: "pMediaControl->Stop();" My entire application closes:-( If I type in this code: "pMediaCotnrol->StopWhenReady();" My application will stop the song but the application freezes and quits.:-( I am unable to run my next song file because the application is quitting all of the time.:-( Thanks for any help you can provide.
