Is there a 'proper' way of disabling the screensaver while an
application is running? Or do I have to simulate user input? I've seen
a pretty clean way to do this, but firing a timer every x seconds
seems a bit lame compared to telling the screensaver to not activate.
I checked out the link Troy sent, using IOKit, and got a bit excited
(because I also felt like periodic "don't sleep" messages are lame ;).
After some testing, however, it looks like that only disables system
sleep and display dimming, not disabling the screen saver. (I could
be mistaken on this, so if I'm incorrect by all means set me straight).
So, if the above is correct, it looks like
UpdateSystemActivity(OverallAct); is still the way to go (every ~30
seconds)... I find that putting it on a background thread is easy
enough (and keeps random timer events off the main thread), but that
might be overkill for your application.
