"One of the key features of Object Oriented Programming (OOP) languages is inheritance. Inheritance is the ability to use all of the functionality of an existing class, and extend those capabilities without re-writing the original class. Prior to the availability of Microsoft® Visual Basic® .NET, Visual Basic programmers did not have this capability. In Visual Basic .NET, you are able to inherit from classes that ship in the Microsoft .NET Framework, as well as from classes that you create. In this document, you will learn how to use inheritance, and see how it can significantly cut down your programming time."
