Take a look at the extensions. Thats just plain old classic .asp
Fact is, you cant just take old .asp files, rename them to asp.net and expect them to work. There are very distint differences in how functions and subrouteens are declaired and managed.
Have fun... www.asp.net has a forum project in the works that resembles snitz. It will be a Microsoft sample application in C# with a VB.NET front end. Source will be available later this year.
