Content preview from Learning Visual Basic .NET

Preface

In July 2000, Microsoft announced the release of its new .NET platform, which represented a major change in the way people think about programming. .NET facilitates object-oriented Internet development. Visual Basic .NET (VB.NET) is a programming language that was adapted from its predecessor, Visual Basic 6, specifically for the purpose of writing applications for the .NET platform. This new version of the Visual Basic language is well suited for developing distributed web applications.

About This Book

Learning Visual Basic .NET is a primer on the VB.NET language, in the context of the .NET development environment, and also on object-oriented programming. This book focuses on the fundamentals of the VB.NET programming language, both syntactical and semantic. After mastering these concepts, you should be ready to move on to a more advanced programming guide that will help you create large-scale web and Windows applications. Chapter 19 provides a number of suggestions for your continued study of VB.NET and .NET development.

Who This Book Is For

Learning Visual Basic .NET was written for programmers with little or no object-oriented programming experience, as well as for novice programmers. Those coming from another language may have a slight advantage, but I’ve tried to provide an on-ramp for beginners as well, by defining all terms, demonstrating the relationships among the various constructs, and reviewing key concepts along the way.
