Okay, okay. I'm calm. Everything's just fine. I'm sure, someone will
tell me that I don't have a BIG, BIG problem.
Because, hey, it's 2001, and of course it should be no problem to play
.wav files from IDL, right? Right.
When I do a
spawn, 'wav.exe mywav.wav' ,
a big DOS window opens. If I use
spawn, 'start /min wav.exe mywav.wav' ,
it closes immedeately, but it is still opened first for a short time.
I also see a small dialog telling me that IDL is spawning a command.
And this is just unacceptable! I want to show images to our patients
which are being tested, and I just cannot confuse them with appearing
and disappearing dialogs. No way.
Any ideas? If not, I really don't know what to do now. And I have to
explain the doctors why the program I wrote this week is of no use.

Hi Alex,
David's absolutely right about IDL 5.4 and Spawn, but if all you need is to
get a .wav file sound played from the PC, you might want to try the
excellent idl_tools utilities by Randall Frank. One of the many marvels in
there is a sound player. It's available at:
http://www.rlkling.com/freeware/randallfrank.html
Then, once you've dropped idl_tools.dll and idl_tools.dlm into your IDL
\bin\bin.x86 directory, all you need to do is:
wav = Read_WAV('c:\winnt\media\chimes.wav', rate)
handle = Snd_Play(wav, rate)
(handle is not anything you need afterward, ignore it)
From what I can tell, Read_WAV came in IDL 5.3, so this may be possible
without the 5.4 upgrade, and you may prefer to have it all handled from
within IDL!
Cheers,
