Visual Basic has always been a language of innovation, but at the same time it's left its proponents wanting certain high-level features. With the upcoming version, Visual Basic .NET, the language takes advantage of the Microsoft .NET Framework to provide several new features that will be vital to developers. This article begins by discussing tracing and error logging in Visual Basic .NET. Next, you'll see how to write a Windows service without third-party help. Monitoring the file system, a previously daunting task, is also covered. Finally, the author ties these concepts together with a sample application that waits for XML files to be deposited in a directory and then imports them into SQL Server database.
