Murach's Visual Basic 2005
How to create and use classes

This chapter shows you how to create your own Visual Basic classes that include fields, properties, methods, constructors, and shared members. While many competing books illustrate these concepts with unrealistic objects such as automobiles or animals, this book uses real-world business objects such as products and customers.

In fact, this chapter presents an application that uses a Product class to create Product objects and a ProductDB class that uses shared methods to handle the application's database access. That's the type of complete application that you need to see if you want to understand object-oriented programming in Visual Basic.
