Mapping (C#)

I'm not answering the question, having never used C#, but generally, if you're asking for help and the opening post in the thread is 3 sentences long and nothing else, you probably haven't provided enough information for anyone to really help you very much.

That being said, isn't C# event-driven. Or, if that means nothing to anyone because I'm using the term improperly, isn't it like VB in that there'll be a specific function that gets called automatically when a mouse click is detected? Keep in mind I said that I've never used it before, so maybe I have some bad information.
