Welcome to Visual Basic .NET and the world of Windows, Internet, and World Wide Web programming with Visual Studio .NET and the .NET platform! This book is the third in the new Deitel Developer Series, which presents leading-edge computing technologies to software developers and IT professionals.
Visual Basic .NET was created from Visual Basic 6.0 by Microsoft expressly for its .NET platform. Visual Basic .NET provides the features that are most important to programmers, such as object-oriented programming, graphics, graphical-user-interface (GUI) components, exception handling, multithreading, multimedia (audio, images, animation and video), file processing, prepackaged data structures, database processing, Internet and World-Wide-Web-based multi-tier application development, networking, Web services and distributed computing. The language is appropriate for implementing Internet- and World-Wide-Web-based applications that integrate seamlessly with Windows-based applications.
The .NET platform offers powerful capabilities for software development and deployment, including language and platform independence. For example, developers writing code in any (or several) of the .NET languages (such as Visual Basic .NET, C# and Visual C++ .NET) can contribute components to the same software product. In addition to providing language independence, .NET extends program portability by enabling .NET applications to reside on, and communicate across, multiple platforms. This facilitates the creation and use of Web services, which are applications that expose functionality to clients over the Internet.
The .NET platform enables Web-based applications to be distributed to consumer-electronic devices, such as wireless phones and personal digital assistants (PDAs), as well as to desktop computers. The capabilities that Microsoft has incorporated into the .NET platform increase programmer productivity and decrease development time.
Deitel & Associates, Inc. currently has two Visual Basic .NET publications, intended for different audiences. We provide information on www.deitel.com, here and inside this book's back cover to help you determine which publication is best for you.
Our first Visual Basic .NET book, Visual Basic .NET How to Program, Second Edition, was published as part of our How to Program Series, for college and university students. It provides a comprehensive treatment of Visual Basic .NET and includes learning aids and extensive ancillary support. Visual Basic .NET How to Program, Second Edition assumes that the reader has little or no programming experience. Early chapters focus on fundamental programming principles. The book builds on this to create increasingly complex and sophisticated programs that demonstrate how to use Visual Basic .NET to create graphical user interfaces, networking applications, multithreaded applications, Web-based applications and more. We encourage professors and professionals to consider the The Complete Visual Basic .NET Training Course. This package includes Visual Basic .NET How to Program, Second Edition, as well as the Visual Basic .NET Multimedia Cyber Classroom, Second Edition, an interactive multimedia CD-ROM that provides extensive e-Learning features. The Complete Visual Basic .NET Training Course, Second Edition and Visual Basic .NET Multimedia Cyber Classroom, Second Edition are discussed in detail later in this Preface.
This book, Visual Basic .NET for Experienced Programmers, is part of the new Deitel Developer Series, intended for professional software developers-from novices through experienced programmers. This publication is a part of the For Experienced Programmers subseries, designed for the experienced software developer who wants a deep treatment of a new technology with minimal, if any, introductory material. Visual Basic .NET for Experienced Programmers provides a brief introduction to programming principles in general and to Visual Basic .NET fundamentals, then delves deeply into more sophisticated topics, such as Web development and distributed computing. There is considerable overlap between this book and Visual Basic .NET How to Program, Second Edition.
A third publication, ASP .NET with Visual Basic .NET for Experienced Programmers, is forthcoming. This book was originally titled Advanced Visual Basic .NET for Experienced Programmers.
Each of our Visual Basic .NET books presents many complete, working Visual Basic .NET programs and depicts their inputs and outputs in actual screen shots of running programs. This is our signature Live-Code approachwe present concepts in the context of complete working programs. Each book's source code is available free for download at www.deitel.com.
Please examine both the Deitel Developer Series professional books and the How to Program Series textbooks to determine which best suits your needs. Visual Basic .NET for Experienced Programmers is derived from Visual Basic .NET How to Program, Second Edition. Depending on your particular needs, you should purchase either this book or Visual Basic .NET How to Program, Second Edition.
This book was written after Visual Basic .NET How to Program, Second Edition. We added to this Deitel Developer Series book a chapter on the new Microsoft Mobile Internet Toolkit for our readers who wish to develop wireless Internet applications for wireless phones, pagers and PDAs. This material will be added to the third edition of Visual Basic .NET How to Program.

This edition contains many features, including:
Visual Basic .NET for Experienced Programmers contains a rich collection of examples that have been tested on Windows 2000 and Windows XP. The book concentrates on the principles of good software engineering and stresses program clarity. We are educators who teach edge-of-the-practice topics in industry classrooms worldwide. We avoid arcane terminology and syntax specifications in favor of teaching by example. The text emphasizes good pedagogy.
We use fonts to distinguish between Visual Studio .NET's Integrated Development Environment (IDE) features (such as menu names and menu items) and other elements that appear in the IDE. Our convention is to emphasize IDE features in a sans-serif bold Helvetica font (e.g., Project menu) and to emphasize program text in a serif bold Courier font (e.g., Dim x As Integer).
Visual Basic .NET for Experienced Programmers is loaded with numerous Live-Code examples. This style exemplifies the way we teach and write about programming and is the focus of our multimedia Cyber Classrooms and Web-based training courses as well. Each new concept is presented in the context of a complete, working example that is followed by one or more windows showing the program's input/output dialog. We call this method of teaching and writing the Live-Code Approach. We use programming languages to teach programming languages. Reading the examples in the text is much like entering and running them on a computer. Readers have the option of downloading all of the book's code examples from www.deitel.com, under the Downloads/Resources link. Other links provide errata and answers to frequently asked questions.
All of the source code for the examples in Visual Basic .NET for Experienced Programmers (and our other publications) is available on the Internet as downloads from the following Web sites:
Registration is quick and easy and these downloads are free. We suggest downloading all the examples, then running each program as you read the corresponding portion of the book. Make changes to the examples and immediately see the effects of those changes-this is a great way to improve your programming skills. Any instructions for running the examples assumes that the user is running Windows 2000 or Windows XP and is using Microsoft's Internet Information Services (IIS). Additional setup instructions for IIS and other software can be found at our Web sites along with the examples. Note: This is copyrighted material. Feel free to use it as you study, but you may not republish any portion of it in any form without explicit permission from Prentice Hall and the authors.
Visual Studio .NET belongs to a family of products that are available for purchase and download from Microsoft. Visual Studio .NET, which includes Visual Basic .NET, comes in four different editions-Academic, Professional, Enterprise Developer and Enterprise Architect. Visual Studio .NET Academic contains Visual Studio .NET Professional's features in addition to features designed for students and professors (e.g., an Assignment Manager that documents assignment submission, Application Publishing Tools that aid in the notification of assignments, code samples and more).
Microsoft also offers stand-alone products (Visual C# .NET Standard, Visual C++ .NET Standard and Visual Basic .NET Standard) for various .NET-languages. Each product provides an integrated development environment (similar to Visual Studio .NET) and a compiler. Visit msdn.microsoft.com/vstudio/howtobuy for descriptions and ordering information.
Each chapter begins with objectives that inform readers of what to expect and gives them an opportunity, after reading the chapter, to determine whether they have met the intended goals.
The chapter objectives are followed by sets of quotations. Some are humorous, some are philosophical and some offer interesting insights. We have found that readers enjoy relating the quotations to the chapter material. Many of the quotations are worth a "second look" after you read each chapter.
The chapter outline enables readers to approach the material in top-down fashion. Along with the chapter objectives, the outline helps users anticipate topics and set a comfortable and effective learning pace.
Approximately 20,300 Lines of Code in 192 Example Programs (with Program Outputs)
We present Visual Basic .NET features in the context of complete, working Visual Basic .NET programs. The programs range in size from just a few lines of code to substantial examples containing hundreds of lines of code. All examples are available as downloads from our Web site,
An abundance of charts, line drawings and program outputs is included.
We have included programming tips to help readers focus on important aspects of program development. We highlight hundreds of these tips in the form of Good Programming Practices, Common Programming Errors, Testing and Debugging Tips, Performance Tips, Portability Tips, Software Engineering Observations and Look-and-Feel Observations. These tips and practices represent the best the authors have gleaned from many decades of programming and teaching experience. One of our customers-a mathematics major-told us that she feels this approach is like the highlighting of axioms, theorems and corollaries in mathematics books; it provides a foundation on which to build good software.
Good Programming Practices are tips that call attention to techniques that will help developers produce programs that are clearer, more understandable and more maintainable.
Developers learning a language tend to make certain kinds of errors frequently. Pointing out these Common Programming Errors reduces the likelihood that readers will make the same mistakes.
When we first designed this "tip type," we thought the tips would contain suggestions strictly for exposing bugs and removing them from programs. In fact, many of the tips describe aspects of Visual Basic .NET that prevent "bugs" from getting into programs in the first place, thus simplifying the testing and debugging processes.
Developers like to "turbo charge" their programs. We have included 39 Performance Tips that highlight opportunities for improving program performance-making programs run faster or minimizing the amount of memory that they occupy.
We include Portability Tips to help developers write portable code and to provide insights on how Visual Basic .NET achieves its high degree of portability.
The object-oriented programming paradigm necessitates a complete rethinking of the way we build software systems. Visual Basic .NET is an effective language for achieving good software engineering. The Software Engineering Observations highlight architectural and design issues that affect the construction of software systems, especially large-scale systems.
We provide Look-and-Feel Observations to highlight graphical-user-interface conventions. These observations help developers design attractive, user-friendly graphical user interfaces that conform to industry norms.
Each chapter ends with a summary that helps readers review and reinforce key concepts.
Approximately 3,683 Index Entries (with approximately 4,490 Page References)
We have included an extensive Index. This resource enables readers to search for any term or concept by keyword. The Index is especially useful to practicing programmers who use the book as a reference.
Visual Basic .NET for Experienced Programmers has 192 Live-Code examples, which we have "double indexed." For every Visual Basic .NET source-code program in the book, we took the file name with the .vb extension, such as ShowColors.vb, and indexed it both alphabetically (in this case, under "S") and as a subindex item under "Examples." This makes it easier to find examples using particular features.
Visual Basic .NET Multimedia Cyber Classroom, Second Edition and The Complete Visual Basic .NET Training Course, Second Edition
We have prepared an interactive, CD-ROM-based, software version of Visual Basic .NET How to Program, Second Edition, called the Visual Basic .NET Multimedia Cyber Classroom, Second Edition. This resource, ideal for corporate training and college courses, is loaded with interactive e-learning features. The Cyber Classroom is packaged with the Visual Basic .NET How to Program, Second Edition textbook at a discount in The Complete Visual Basic .NET Training Course, Second Edition. If you already have that book and would like to purchase the Visual Basic .NET Multimedia Cyber Classroom, Second Edition separately, please visit www.InformIT.com/cyberclassrooms. The ISBN number for the Visual Basic .NET Multimedia Cyber Classroom, Second Edition is 0-13-065193-1. Many Deitel Cyber Classrooms are available in CD-ROM and Web-based training formats.
The CD-ROM provides an introduction in which the authors overview the Cyber Classroom's features. The textbook's 249 Live-Code example Visual Basic .NET programs truly "come alive" in the Cyber Classroom. If you are viewing a program and want to execute it, you simply click the lightning-bolt icon, and the program will run. You immediately will see-and hear, when working with audio-based multimedia programs-the program's output. Click the audio icon, and one of the authors will discuss the program and "walk you through" the code.
The Cyber Classroom also provides navigational aids, including extensive hyperlinking. The Cyber Classroom is browser based, so it remembers sections that you have visited recently and allows you to move forward or backward among those sections. The thousands of index entries are hyperlinked to their text occurrences. Furthermore, when you key in a term using the "find" feature, the Cyber Classroom will locate occurrences of that term throughout the text. The Table of Contents entries are "hot," so clicking a chapter name takes you immediately to that chapter.
Readers like the fact that solutions to approximately half the exercises in Visual Basic .NET How to Program, Second Edition are included with the Cyber Classroom. Studying and running these extra programs is a great way for readers to enhance their learning experience.
Professionals and student users of our Cyber Classrooms tell us that they like the interactivity and that the Cyber Classroom is an effective reference due to its extensive hyperlinking and other navigational features. We received an e-mail from a reader who said he lives "in the boonies" and cannot attend a live course at a university, so the Cyber Classroom provided an ideal solution to his educational needs.
Professors tell us that their students enjoy using the Cyber Classroom and spend more time on the courses and master more of the material than in textbook-only courses. For a complete list of the available and forthcoming Cyber Classrooms and Complete Training Courses, see the Deitel Series page at the beginning of this book, the product listing and ordering information at the end of this book or visit
