Prevent windows from going into sleep when my program is running?

I have to stop windows from going into sleep when my program is running.

And I don't only want to prevent the sleep-timer, I also want to cancel the sleep-event if I press the sleep-button or in any other way actively tell the computer to sleep. Therefore SetThreadExecutionState is not enough.

Or...I don't actually have to prevent the sleep completely, only delay it 5-10sec to allow my program to finish a task.

(I know that this is bad program behavior but it's only for personal use.)

windows winapi sleep

Using PowerCreateRequest, PowerSetRequest, and PowerClearRequest functions is the preferred method. Details and sample code (C/C#) are inside http://msdn.microsoft.com/en-us/library/windows/hardware/gg463205.aspx
