Determining what has been selected?

Hi,
I firstly want to dertermine if one of my pushpins has been selected, I have tried using the SelectionChange even but I can't figure out how to determine it a pushpin and not a shape etc.

Secondly I want to display a small form (like a menu box) near the pushpin when the user right clicks one of my pushpins can this be done?

Thanks

I posted a function for doing this (First part of your question), here is the link:
