Do you know if it is possible to create a code that can modify the system volume in PocketC ?
Thanks for your support!

By the "System Volume", do you mean the object store, or do you mean the volume of the sound output?

If you mean the sound output volume, then you can do this with the waveOutSetVolume() function:

waveOutSetVolume(WAVE_MAPPER, 0xffffffff) ; // Full volume
waveOutSetVolume(WAVE_MAPPER, 0x00000000) ; // Silent
waveOutSetVolume(WAVE_MAPPER, 0xffff0000) ; // Full on right, silent on left

You need to install the developer CEAPI library for PocketC, then #include /pocketc/mmsystem.h in your PocketC source file.

The documentation for waveOutSetVolume() is at:

http://msdn.microsoft.com/library/en-us/wcesdkr/htm/_wcesdk_Win32_waveOutSetVolume.asp?frame=true

If you distribute a program that uses the CEAPI library you have to either include the library for each platform in your distribution, or tell the users where to get the runtime.

You can download CEAPI for PocketC by following the link in my sig below.

If you have a PocketPC2002 the installation will tell you that it wasn't designed for your hardware. It was, install it regardless.
