Let's say I have 5 boolean values: [CODE] bool a; bool b; bool c; bool d; bool e; [/CODE] If they evaluate as true 'a', 'b', 'c' and 'd' should have their associated code run. If 'e' evaluates as true then only its associated code is run and the values …

I would like to write a class that handles a series of timed events for an object. I would need to deal with class properties not being set, and therefore making no change to the object. I've gone with the "?" nullable operator for my first attempt but I would …
