Overview In this session, you will learn the basics of Object Oriented Programming (OOP). You will learn the terminology and see how Visual FoxPro supports OO techniques. You will also learn about the Object Browser, a tool used to maintain class libraries. Finally, the session will cover the Fox Foundation Classes, a group of classes that ship with Visual FoxPro that you can use in your applications. Terminology Before you can begin using OOP, it s important to know the terminology used. Many of the terms are simply names for things you may already know. Others may be new to you. Class The basic and most important concept you will deal with is a class. A class is a template that specifies the attributes and behavior of something. A class models a real world thing, such as an invoice. When discussing an invoice class, you are not talking about a specific invoice, but rather a description of an invoice. You don t even include specific data items in a class.
