Murach's Visual Basic 2008
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.
