>>I have a main program that instantiates a class. That class contains various objects. What is the best way to clean-up all the references? This program is a service that starts on boot and remains running until PC shutdown or the service is terminated. What can I put in my program/classes to ensure I don't leave stuff hanging around? Per Cathy's suggestion, I'll set them to NULL after destroying them, but where best to do that?
