Online Programming with Visual Basic course

This class is an introduction to the Visual Basic (formerly VB.NET) programming language. It will cover the concepts and building blocks of the Visual Basic programming language, such as how .NET is different from traditional programming, defining variables, control structures, operators, classes and methods. It will provide delegates with a skill base from which they can go on to develop .NET applications on either the Windows Forms or ASP.NET platforms.

Please note that this is the .NET version of Visual Basic (version 7 and above). It is not suitable if you want to learn VB6 or below, or Visual Basic for Applications (VBA). Please contact us if you are unsure if this is the right course for your VB requirements.
