Object-Oriented Programming in Visual Basic

Objects are central to Visual Basic programming: Forms and controls are objects. Databases are objects. If you have used Visual Basic for a while, or if you have worked through the examples in the documentation, then you have already programmed with objects, but there is a lot more to objects than what you have seen so far.

In the following topics, you will see how easy it is to create your own objects from the classes you define and to use objects to simplify your coding and increase code reuse.

In This Section

• Introduction to Objects in Visual Basic
  Provides an introduction to the terms and concepts used in object-oriented programming.

• Understanding Classes
  Provides an overview of classes and an example of how to define a class.

• Creating and Using Objects
  Shows how to create and use instances of classes.

• Collections in Visual Basic

• Inheritance in Visual Basic
  Describes how to define classes that serve as the basis for other classes.

• Shared Members in Visual Basic
  Describes members that can be used without instances.

• Early and Late Binding
  Describes binding, which is performed by the compiler when an object is assigned to an object variable, and the differences between early-bound and late-bound objects.
