This thread is for discussions of Play a WAV file.

SND_FLAG

this Variable is not defined it says....Now What?

Values for the SND_FLAG variable are defined in the MMSYSTEM.H file (found in the C:\Program Files\Microsoft Visual Studio .NET\Vc7\PlatformSDK\Include folder on my machine.)

The following variables are defined:
/*
*  flag values for fuSound and fdwSound arguments on [snd]PlaySound
*/
#define SND_SYNC            0x0000  /* play synchronously (default) */
#define SND_ASYNC           0x0001  /* play asynchronously */
#define SND_NODEFAULT       0x0002  /* silence (!default) if sound not found */
#define SND_MEMORY          0x0004  /* pszSound points to a memory file */
#define SND_LOOP            0x0008  /* loop the sound until next sndPlaySound */
#define SND_NOSTOP          0x0010  /* don't stop any currently playing sound */

I recommend setting the variable to 1 (SND_ASYNC) -- this allows the program to continue executing while the sound file is playing in the background, instead of waiting for the sound clip to finish.

Good luck.  

   Private Const SND_FLAG = &H1 Or &H2

I tried it, and it won't stop... VB itself keeps playing the file until I close it. What you can do to stop it is Call PlayWav(vbnullstring) - playing a nonexistant file will stop any current file.
Now, anyone know how to tell how much is loaded, and how to play an MP3 this way (IE without a Windoze Media Control)?
