Hello Guys,
I am developing an application that scans Pocket PC files
but I want to pause scanning when phone call is coming and resume it
automatically once it's finished. I am just wandering how to get phone call
notification in my application ?

Could anybody help me please?

Thanks,

If your device is Windows Mobile 5, you can use SystemState class from
Microsoft.WindowsMobile assemblies.
 
Thanks Alex. I just developed an application using 'SystemState' class and
able to get notification for incoming call but how to get notification when
call finishes?

Could you please help me out?

Thanks,

Santosh,

You could subscribe to either PhoneCallTalking or PhoneActiveCallCount.
When the state of a phone call changes, e.g. a user starts talking,
puts a call on hold, or hangs up, an event will be fired. For example,

SystemState statePhoneCall = new
SystemState(SystemProperty.PhoneCallTalking);
statePhoneCall.Changed += new
ChangeEventHandler(OnStatePhoneCallChanged);

private void OnStatePhoneCallChanged(object sender, ChangeEventArgs
args)
{
//we know we can cast args.NewValue to a bool here because
//SystemState.PhoneCallTalking returns a bool
bool bTalking = (bool)args.NewValue;
Debug.WriteLine((bTalking ? "Talking" : "NotTalking"));
}

Hope this helps,

Jon
