This does not work. Is the call to PreventSleep should be periodic?
I wired it the PreventSleep and AllowSleep to buttons - tried it out but does not work...

In my program, it works if you don't press the 'Power saving button' in Windows. & you don't have to call PreventSleep periodically
I got this to work, after spinning a thread and calling the PreventSleep() every minute. Thank you and awesome work!

It is setting method so, call once in constructor then, it is ok.
Thank you for your code.
