No you can't have vb files in a windows or console application but YES you can inside a web application You just redirect the file pointer at the top of the aspx page, You can have many different files including java files in there. Although .net transforms it into J# and is utterly useless with J2EE at that point. Just go to add existing item and add the code behind. Then at the top of your asp page change the finlename it points to and thats all there is to it. nick I'm not an expert yet, but I play one at work. Yeah and here too.
