Visual Basic.NET:

Microsoft Visual Basic (called VB) is a new programming language designed for building a wide range of enterprise applications that run on the .NET Framework. An evolution of Microsoft Visual Basic, Visual Basic .NET is simple, modern, type safe, and object oriented. Visual Basic .NET code is compiled as managed code, which means it benefits from the services of the common language runtime. These services include language interoperability, garbage collection, enhanced security, and improved versioning support. Visual Basic .NET leverages the Microsoft .NET Framework to provide a rich set of built-in types that you can use when building your own classes. A subset of these types can be used for interacting with other .NET languages. The .NET Framework also provides an extensive class library that you can use and extend with Visual Basic .NET.As with all object-oriented languages, Visual Basic .NET promotes reuse through classes. A class defines a type as well as the methods and properties that are used to interact with instances of the type. For example, a class that represents an animal might include methods that represent the animal’s activities (such as eating and sleeping) and properties that represent i ts characterist ics (such as color or size). The main design goal of Visual Basic .NET is simplicity rather than pure power. You do give up a li ttle processing power, but you get cool stuff like type safety and automatic garbage collection in return. Visual Basic .NET can make your code more stable and productive overall, meaning that you can more than make up that lost power in the long run. Visual Basic .NET offers several key benefits for programmers:

o Simplicityo Consistencyo Modernityo Object-orientationo Type-safetyo Scalabili tyo Version supporto Compatibil ityo Flexibility
