Chapter 1

This book introduces you to Visual Basic (VB) 2008 programming. It is oriented toward business applications, with a design perspective. Many business applications involve data-entry operations. On appearance, data entry appears to be a fairly simple programming task. However, once you start to develop this type of application program, you will encounter many intriguing issues. For example, as soon as you start to design the data-entry screen, you will wonder how to best design the visual interface; thus, you will be faced with interface design issues. In addition, you will have to develop code to validate the data entered by the user because data accuracy is of the utmost importance to any business. Here, you may encounter a lot of duplicate code; thus, you will need to design the code structure to minimize duplication. Business applications also involve data storage and processing; therefore, you will need to deal with data management issues and develop algorithms to process data efficiently. This book is oriented toward handling these issues.
This chapter gives an overview of VB programming. Naturally, when you are learning VB programming, your first question is, “What is Visual Basic?” Section 1.1 provides some explanations. Section 1.2 examines what constitutes a sound application program. This chapter also discusses the steps involved in developing a program. Section 1.3 provides some suggestions on how to use this book.
