Breif Idea About Visual Basic
VB Language
Visual Basic, the name makes me feel that it is something special. In the History of Computing world no other product sold more copies than Visual Basic did. Such is the importance of that language which clearly states how widely it is used for developing applications. Visual Basic is very popular for it's friendly working (graphical) environment. Visual Basic. NET is an extension of Visual Basic programming language with many new features in it. The changes from VB to VB .NET are huge, ranging from the change in syntax of the language to the types of projects we can create now and the way we design applications. Visual Basic .NET was designed to take advantage of the .NET Framework base cl***es and runtime environment. It comes with power packed features that simplify application development.
The biggest change from VB to VB .NET is, VB .NET is Object-Oriented now. VB .NET now supports all the key OOP features like Inheritance, Polymorphism, Abstraction and Encapsulation. We can now create cl***es and objects, derive cl***es from other cl***es and so on. The major advantage of OOP is code reusability
The Command Button now is Button and the TextBox is TextBox instead of Text as in VB6
Many new controls have been added to the toolbar to make application development more efficient
VB .NET now adds Console Applications to it apart from Windows and Web Applications. Console applications are console oriented applications that run in the DOS version
All the built-in VB functionality now is encapsulated in a Namespace (collection of different cl***es) called System
New keywords are added and old one's are either removed or renamed
VB .NET is strongly typed which means that we need to declare all the variables by default before using them
VB .NET now supports structured exception handling using Try...Catch...Finally syntax
The syntax for procedures is changed. Get and Let are replaced by Get and Set
Event handling procedures are now p***ed only two parameters
The way we handle data with databases is changed as well. VB .NET now uses ADO .NET, a new data handling model to communicate with databases on local machines or on a network and also it makes handling of data on the Internet easy. All the data in ADO .NET is represented in XML format and is exchanged in the same format. Representing data in XML format allows us for sending large amounts of data on the Internet and it also reduces network traffic when communicating with the database
VB .NET now supports Multithreading. A threaded application allows to do number of different things at once, running different execution threads allowing to use system resources
Web Development is now an integral part of VB .NET making Web Forms and Web Services two major types of applications
