.NET Forum / .NET Framework / Compact Framework / January 2006Detecting Runing WAV file
Hi All, How could i detect if a Runing wav file have finished or not, so i could begin playing another file after the first is finished. Thanks in advance.. Regards Tamer Hesham Have you seen inside OpenNETCF.Multimedia.Audio.Player class? Take a look at DonePlaying wavedonehandler. You assign it as the typicak EventHandler. It is fired when the audio file is finished playing. Hope it helps. I have some problems when i try to use OpenNETCF, when i use play function, it runs good, when i use stop function it stops the runing wav file, but when i try to play again, it fails. Any way , is there a way to detect the file by using an API or it is difficult to be done?? Thanks Tamer Hesham You can detect when the file has finished with the handler I've told you. Works ok. What errors are you having when playing second time? Just it does not play, or any error is thrown? Maybe you need something like www.fmod.org, a free and awesome music library for the Compact Framework. Regards. When i play file for the second time, an exception thrown that file not open, and also, the wav file when it is played is not good in quality. The playsound API is good. could i use the event direct not from the OpenNet dll? regards.. Use PlaySound synchronously. When the next line of code executes, it's done playing. -Chris > When i play file for the second time, an exception thrown that file not > open, > and also, the wav file when it is played is not good in quality. > The playsound API is good. > could i use the event direct not from the OpenNet dll? > regards.. Yes, but now i have to wait till the file ends, so i can't for example increase decrease volume, stoping the file or do anything else till file runing ends. Tamer Well put the call on another thread then - this really isn't as complicated as you're making it out to be.  SignatureChris Tacke Co-founder OpenNETCF.org Are you using the SDF?

Tamer Hesham Have the thread raise an event or set a flag variable. -Chris > Okay, i made a thread and called the play function from it, and it worked > well, but how could i know that the thread is terminated so i could know [quoted text clipped - 4 lines] > > Tamer Hesham Or do a WaitForSingleObject() on the thread handle, if you have access to that result of CreateThread(). The thread handle will be signaled when the thread has exited...
