defining own events for notification and sounds

[dima2]

hi,

I'm developping a pocket pc application using evc and
I was wondering if there's a way that I can define my own events for notification and sounds.

I noticed that in the registry under ControlPanel\Notification there are some event names that would appear when the user enters Settings\Sounds&Notification
like for example "MSN:Contact Online" where the wav file and options are saved.

So I thought maybe if I could add my own entry in the registry I might be able to add an event of my own. That way I could present it to the user in the Settings\Sounds&Notification and he would be able to edit notification and sounds.
Is that possible???

If so:
- how do I define/register the event
- how do I fire it programmatically from inside my application
- under what key value should I add the info in the registry

any idea would be greatly apreciated
thanks a lot
