How to stop a PDA sleeping

I have an application for PDAs with a long running process, and I'm getting the problem that the PDA is going to sleep before the process has completed.

I haven't got any control over the power settings on the PDA, does anyone know a good way for my application to stop the PDA from going to sleep?

Many thanks

• You need to make a function that calls SystemIdleTimerReset, SHIdleTimerReset and simulates a key touch. Then you need to call it on a regular basis from within your application.

  For an example in C++, look here:

• Have a look at:
