How to detect phone power down

[Guest monikker]

I work on an application that needs to do some actions at exit. No problem when user exits it but what if phone is just turned off? I did some tests and it seems that neither WM_CLOSE nor WM_DESTROY are sent when phone is turned off. Is there any way to detect when phone is about to turn off? (Or even better is there a way to detect and delay this for a while?)

I'm not sure if this is possible or not, but could your application intercept the power button before it gets through to the operating system, close gracefully and then send a software power off command?
