Event - when click on Drawing View

Hi It's my first post here. I'm just starting programing with "Solid Edge". My knowledge of VB is basic. I'm trying to do event: each time when i click on a drawing view (or part in Assembly), i want information about the event (e.g. MsgBox). I've read many posts here and i tried several solutions, but my code doesn't working. I tried "SelectSetChanged", but Visual Studio 2012 doesn't return any error and my code does nothing. I don't know, if i do it right. I would be grateful for some help and samples.
Sorry for my english.
