I don’t really understand your code example. But the way events work, you can’t have a return value. A way to do something similar in an OOP manner would be, to use a property in a CEvent object (or some extended class) that you pass along when you trigger the event. Every handler will receive this event object and can alter its properties. After all handlers did their job, you can inspect this property.
