The lessons for Week 1 get you started in object-oriented programming concepts in Visual Basic. You learn object-oriented analysis, design, and programming, as well as class inheritance and building ActiveX components. |

The week begins with a survey of fundamental concepts in object-oriented programming that provides the foundation for the remaining lessons in the book. Then you progress through the essentials of object-oriented analysis; you learn how to discover important entities or abstractions in your user requirements and other sources in your domain. You then move into the fundamentals of object-oriented design. This includes the creation of class diagrams that reflect the Visual Basic class modules you'll discover you need, as well as interaction diagrams that show how these classes interact to carry out user requirements. |

In the middle of the week, you begin to apply the concepts of object technology and receive a lesson on object-oriented programming. In this lesson, you're going to take your learning a step further. You learn how to construct actual Visual Basic code from the simple sequence diagrams you created in previous lessons. |

Toward the end of the week, you learn about class interface inheritance, in which one class implements the interface (public methods and properties) of another class. From there it's a short step to learning to build simple ActiveX components. The week wraps up with a look into the adaptation and reuse of third-party components, which allows you to reduce your development requirements. |
