Question

I want to use a timer in a windows mobile app. Of course, this is not the problem.

The problem: the timer needs to be called even during standby and sleep mode.

Simply switching off the sleep mode is not really an option, since the app needs to comply to windows marketplace for mobiles requirements, and regarding to requirement 5.2 a marketplace app “shall not modify power management options”.

Is there a system timer, which could be used to get an event called (like CeSetUserNotificationEx can be used to get an app started)?
Or how would I create a persistent timer?

Answer 1

CeRunAppAtTime can be used to set a named system event (not just to run an app). If the device is in sleep mode when that time arrives, it will wake.
