In this book/CD-ROM using working programs as examples, chapters walk readers through sample applications that illustrate points about Visual Basic .NET. The book covers essentials of object-oriented programming in Visual Basic .NET and explains how to build classes and work with the .NET Framework classes, how to work with arrays and collections, and how to debug and handle errors in programs. It also covers working with .NET assemblies, files, and data streams, monitoring files over a network, and Web services. The CD-ROM contains a searchable electronic copy of the book, and sample code written in Visual Basic .NET.
