Hi guys,
I'm using .net cf and i was wondering whether there was a function or procedure that already exists that will detect when the user last interacted with their pda or return the time the back light was switched off.
This is because i have a program that attempts to upload or download some files and i want to set a flag so that if the user is using their pda then the upload/download function will not be called.

Thanks in advance for any help
