The World Wide Web, for much of its existence, has been a method for distributing passive information to a widely distributed number of people. The Web has, indeed, been exceptionally good for that purpose. With the addition of forms and image maps, Web pages began to become interactive—but the interaction was often simply a new way to get at the same information. The limitations of Web distribution were all too apparent once designers began to try to stretch the boundaries of what the Web can do.

Object-Oriented Programming (OOP) Inheritance - form of software reusability New classes created from existing ones Absorb attributes and behaviors, and add in their own Override methods - redefine inherited methods Subclass inherits from superclass Direct superclass - subclass explicitly inherits Indirect superclass - subclass inherits from two or more levels up the class hierarchy Polymorphism Write programs in a general fashion to handle a wide variety of classes Abstraction - seeing the big picture...

Beginning Object-Oriented Programming with VB 2005 is a comprehensive resource of correct coding procedures. Author Daniel Clark takes you through all the stages of a programming project, including analysis, modeling, and development, all using object-oriented programming techniques and Visual Basic .NET. Clark explores the structure of classes and their hierarchies, as well as inheritance and interfaces. He also introduces the .NET Framework and the Visual Studio integrated development environment, or IDE. A real-world case study walks you through the design of a solution.

The precursors of object-oriented programming can be traced back to the late 1960's: Classes, inheritance and virtual member functions were integral features of Simula67, a programming language that was mainly used for writing event-driven simulations. When Smalltalk first appeared back in 1972, it offered a pure object-oriented programming environment. In fact, Smalltalk defined object-oriented programming. This style of programming was so innovative and revolutionary at the time that it took more than a decade for it to become a standard in the software industry.

I am an admitted object-oriented fanatic. I have been designing and implementing object-oriented software for more than twenty years. When I started designing and implementing object-oriented MATLAB ® , I encountered many detractors. They would say things like “The object model isn’t complete,” “You can’t have public variables,” “The development environment doesn’t work well with objects,” “Objects and vector operations don’t mix,” “Object-oriented code is too hard to debug,” and “MATLAB objects are too slow.” None of these statements matched my experience with MATLAB objects.

"Refactoring" was conceived in Smalltalk circles, but it wasn't long before it found its way into other programming language camps. Because refactoring is integral to framework development, the term comes up quickly when "frameworkers" talk about their craft. It comes up when they refine their class hierarchies and when they rave about how many lines of code they were able to delete. Frameworkers know that a framework won't be right the first time around—it must evolve as they gain experience.
