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.

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.

Shared Members in Visual Basic

Describes members that can be used without instances.

Creating and Using Objects

Shows how to create and use instances of classes.

Managing Groups of Objects

Provides techniques for working with arrays and collections of objects.

Obtaining Class Information at Run Time

Shows how to determine the class that an object belongs to.

Understanding Classes

Covers object creation and lifetime issues in a step-by-step procedure.

Events in Visual Basic

Shows how to declare and use events.

Delegates in Visual Basic

Shows how to declare and use delegates.

Interfaces in Visual Basic

Describes what interfaces are and how you can use them in your applications.

Inheritance in Visual Basic

Describes how to define classes that serve as the basis for other classes.
