The safest way to idle a delphi application to wait for a timer?

Question

I am making a delphi application that will run on my computer 24/7 in the background and checks if it needs to do something or not, wait 30 minutes and check again, etc.

How can I make sure that the application will not overload the processor or memory due to the fact that it works all the time.

Answer 7

I would suggest creating a service application (set the startup type as automatic) and use CreateTimerQueueTimer as a timer. Memory leaks can be mitigated by reserving memory requirements / pool classes.
