Object Oriented Programming 2 – Class Library Files

This is the second in a series of videos which introduce object oriented programming (OOP) using Visual Basic.NET (VB.NET). This video explains the use of class library files, namely, dynamic link libraries (.dll files). It covers how to write class code inside a VB.NET Class Library project, compile it as a binary .dll file then reference and use it from within a Windows Forms Application project. A discussion of some of the benefits of using class libraries is also included, specifically, opportunities for code reuse, easy upgrade and maintenance of applications and distributed applications. Later videos in the series will cover property procedures, constructors, method overloading and inheritance.
