Setting default application

Hi all, Im currently wokring on a little mini browser in C# and im trying to find a way to set it as the default browser using a dialog, similar to what you see in fire fox, etc.

I would be very greatful if someone could indicate a way or maybe share some code to help. I know there is a key in the registry however, I don't know where the key is and how i change it and/or add a new one for my application. 

Thanks a lot.
