Hello World, I have just suscribed and I'd like to solve a little problem with your help. Excuse my spanglish. Up to now, I was working with CallBack functions to manage a multibuffer thread with W9x. The appropiate WOM_DONE messages was comming over the process and, naturally, the buffer count was easy inside the CB func. This way, some functions like waveOutUnprepareHeader, waveOutClose and 'FreeMem' were called at the end of the audio sequence. Finally I'd recive a WOM_CLOSE message. Fine! Now I'm checking it with Windows XP. Almost every Buffer is sent to the output device, but the WOM_CLOSE message is missing. In addition, there are 'collateral damage' making new buffers and waveheaders. ¿?¿¿ I would be very pleased if you could help me about this subject. Anyway, than you for your time. Regards, Joaquin. _________________________________________________________________ Descubre el mayor catálogo de coches de la Red en MSN Motor. http://motor.msn.es/researchcentre/ ****************** WDMAUDIODEV addresses: Post message: mailto:wdmaudiodev@xxxxxxxxxxxxx Subscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=subscribe Unsubscribe: mailto:wdmaudiodev-request@xxxxxxxxxxxxx?subject=unsubscribe Moderator: mailto:wdmaudiodev-moderators@xxxxxxxxxxxxx URL to WDMAUDIODEV page: http://www.wdmaudiodev.de/
