Welcome to Visual Basic .NET
The goal of this third edition is to help you come up to speed with the Visual Basic .NET language
even if you have never programmed anything before. You will start slowly, and build on what you
learn. So take a deep breath, let it out slowly, and tell yourself you can do this. No sweat! No kidding!

Programming a computer is a lot like teaching a child to tie their shoes. Until you find the correct
way of giving the instructions, not much gets accomplished. Visual Basic .NET is a language in
which you can tell your computer how to do things. But like a child, the computer will only
understand if you explain things very clearly. If you have never programmed before, this sounds
like an arduous task, and sometimes it is. However, Visual Basic .NET gives you a simple language
to explain some complex things. Although it never hurts to have an understanding of what is
happening at the lowest levels, Visual Basic .NET frees the programmer from having to deal with
the mundane complexities of writing Windows programs. You are free to concentrate on solving
problems.

Visual Basic .NET helps you create solutions that run on the Microsoft Windows operating system.
If you are looking at this book, you might have already felt the need or the desire to create such
programs. Even if you have never written a computer program before, as you progress through the
Try It Outs in this book, you will become familiar with the various aspects of the Visual Basic .NET
language, as well as its foundation in Microsoft’s .NET Framework. You will find that it is not nearly
as difficult as you have been imagining. Before you know it, you will be feeling quite comfortable
creating a variety of different types of programs with Visual Basic .NET. Also, as the name implies,
Visual Basic .NET can be used to create applications for use over the Internet and newly
incorporated into Visual Studio .NET 2003 for its ability to create smart device applications (Pocket
PCs and SmartPhones). However, while learning any new technology, you have to walk before you
can run, so you begin by focusing on Windows applications before extending your boundaries to
other platforms.
