CommManager (Ring or Vibrate)

[Roger Odermatt]

Hello

I have a HTC P4350 and i want make a little application to switch between
RING and VIBRATE with a schedule.

So when i going into the CommManager on my Device, then i have a function to
set my device to ring or to vibrate. When i set i to ring or vibrate, is
this setting in the registry? When yes, where can find it?

My Idea is, when i can find this setting in the registry, then i can design
my application so, that i read and write the registry and can so switch
between RING and VIBRATE by scheduling.

Can anybody help my?

regards
Roger

HKEY_CURRENT_USER\ControlPanel\Sounds\RingTone0

But now i can read value from the registry, but when i want write a new
value then i have a error
System.UnauthorizedAccessException

Want i must do, to write values to the registry?

Thank you very much

Your app likely needs to be signed.
