What is the best way to get started with VB Classes ?

Hello I have been coding all my aspx pages directly on the pages with no call to classes for efficency. Does any one know a good starting point to get up to speed on classes in VB ? I understand the reason for them and have used them in other languages but never in .NET.

I do not know where to start. Like I said I currently have most function written directly on the aspx pages themselves and would like to modularize some of those functions by utilizing classes.

Also all of my applications are web application not client.

Any Help ?For one, you should use VS.Net, it generates page class files (code behind) automatically for you when create your aspx pages.

Also, you can use VS.Net to create Class files that will be shared between your application. All you have to do is reference the Classes in your code behind pages.
