ASP .NET Web Apps



Using Visual Basic .NET 2003


These web pages hope to show how to use ASP .NET to easily create web applications, especially those that provide a front-end to a database. Visual Basic .NET 2003 will be used as the programming language. A Visual Basic .NET 2005 version of these webpages is also available. This 2003 version is no longer maintained.

Most of the examples assume that you are already familiar with introductory programming in a language that is at least similar to Visual Basic. The examples that manipulate a database assume that you already know basic database concepts, such as what tables and queries are. The database examples use SQL Server but a background in Access, Oracle, or similar should be sufficient.
