How to know the user’s inactivity?

How to know the user’s inactivity from an application. Actually if user is inactive for a period I have to trigger some code. How can I do this. Please help.

You will need a timer and reset it everytime there's some action, the attached sample displays a message box if the user has been inactive for 10 seconds.

Thank you for the quick reply. It was really helpful. But I have so many panels and buttons in my application. Do I need to write the reset code on all the button and panels click events? Is there any simple way to do this?

No, that's the way it has to be done, how else can you determine the user is actually using the app?, if there's another way, I'd like to know also.

Maybe ScreenOff event from PhoneEvents?

touch event

it might be good enough to override this sub and update the last visit time

Sub Activity_Touch (Action As Int, X As Float, Y As Float)
   lastTimeAlive = DateTime.Now
End Sub

of course you need to set the timer, and remember to shut it down on activity pause sub, and turn it on on resume sub, etc
