NewFilePlayerL problem..help me pls..

[etamburini]

Hi!
I'm trying to use:

iMdaAudioPlayerUtility = CMdaAudioPlayerUtility::NewFilePlayerL(KSoundFile, *this);

inside the AppContainer, in order to play sounds..

But there is this error in the second parameter:
error C2664: 'CMdaAudioPlayerUtility::NewFilePlayerL' : cannot convert parameter 2 from 'CAppContainer' to 'MMdaAudioPlayerCallback &'

(I have include <MdaAudioSamplePlayer.h>)

Help me, pls..

the AppContainer shoud derive from MMdaAudioPlayerCallback ,like this :

class MyAppContainerublic MMdaAudioPlayerCallback,
......
.......
{
.....
}
