Enable/Disable system sound.

Hello.

I'd like to programatically toggle the system sound.
Right now, I change the device volume whenever I need to enable or disable
the sound, but I'm not very satisfied with this solution. I don't want to
prevent the user from changing the volume or the sound settings, I just want
to be able to toggle the system sound on and off when my application is
running.

Thanks in advance.

What's "the system sound"? It sounds to me like what you're already doing
is fine. If you set the system sound level to 'off' when your program
starts, that doesn't prevent the user from adjusting it manually again any
time during the run of your application. If you, when your application
exits, check the current setting and, if it's 'off', set it back to what it
was before your application started, that seems like a perfectly fine
solution.

System sound for me would be the whole device capability of playing sounds,
including songs, videos, notifications...
Right now I'm using the volume control, saving the initial volume and
setting it to 0 to mute the device, but the sound is still enabled.
What I'd like to do is toggle it on and off without changing the volume.
I know there is an on/off switch on the sound control displayed on the menu
bar, but I don't know how to change it programatically.

You could do something like the following to disable all sound:

SNDFILEINFO sfi;
sfi.sstType = SND_SOUNDTYPE_NONE;
SndSetSound(SND_EVENT_ALL, &sfi, TRUE);

SND_SOUNDTYPE_ON will re-enable it.

Unfortunately this is only available since WM 5.
I'm looking for something for WM 3, or even better, WinCE 3.0

Ahh, I don't think there's any documented way pre WM5. I'd love to be
proven wrong.
