Here are some search terms you can use when googling for resources (tutorials, books, etc.):
ASP.Net
-Used to build web applications.
SQL Server
-A database to store data used by web applications.
VB.Net SQL
-This combination should yield results of how to interact
with a database from VB.Net.
HTML
-You need to know this to develop for the web.
JavaScript
-This can make your web apps faster, but you don't always
need to know this.
You should also pick up a book on some of these topics. Some books actually cover most of these topics all in the same book. Also, if you aren't set on learning VB.Net, I suggest you learn C# instead. The syntax just makes more sense, if you ask me. Good luck!
