Assigning an icon to an extension saved by .net application

[A.Najafi]

Hi All,
Using Visual studio 2008, I have an application that its data can save to a binary file, using *.SDB extension, Moreover users can open this file from my application. I have 2 questions about this.
1- How can I assign an icon to this saved file with SDB extension when my application has been installed in other computer?
2- Similar to *.sln file (for Visual Studio project), How can I assign tow icon to single extension? For example when a solution is saved with visual studio 2005 its icon different from that one saved from visual studio 2008. In first, the solution’s icon contains “5” but in 08 solution’s icon contains “8”.
Thanks Again.

It's a registry entry. Take a look at this article - http://www.codeguru.com/vb/gen/vb_system/directoriesandfiles/article.php/c4837/
