Re: [Dev-C++] Directx 9 - DirectSound problem

Hello,

 Thanks for response.

 I got it:
 The third parameter was wrong, should be:
  LPDIRECTSOUNDBUFFER lpDSBuffer;

  IDirectSound_CreateSoundBuffer( lpDS, &dsbd, &lpDSBuffer, NULL );

 I still don't know what doesn't it compile without modyfing dsound.h and
mmsystem.h. do you have the same problem?

 Thanks,
 Marek
