I am hereby taking reference from some well known books of Prentise Hall and Tata McGrawHill writing a short tutorial about Visual Basic, stating what is VB and its related features and a short example.

What is Visual Basic?
A Microsoft® programming language descended from earlier versions of BASIC. Visual BASIC® is a Windows-specific version of BASIC with many added "bells and whistles" to allow developers to create GUI Windows™ applications. BASIC and Visual BASIC are good languages for novices and occasional developers to learn as it is relatively straightforward to learn and has numerous built-in tools to assist in debugging applications. Visual BASIC can be used to develop CGI applications for Web servers although Perl, C/C++, Python, and other such non-GUI programming languages are frequently better suited for developing CGI and Web server applications.

A brief description of Visual Basic
VISUAL BASIC is a high level programming language evolved from the earlier DOS version called BASIC. BASIC means Beginners' All-purpose Symbolic Instruction Code. It is a fairly easy programming language to learn. The codes look a bit like English Language. Different software companies produced different version of BASIC, such as Microsoft QBASIC, QUICKBASIC, GWBASIC ,IBM BASICA and so on.
VISUAL BASIC is a VISUAL and events driven Programming Language.These are the main divergence from the old BASIC. In BASIC, programming is done in a text-only environment and the program is executed sequentially. In VISUAL BASIC, programming is done in a graphical environment. Because users may click on a certain object randomly, so each object has to be programmed independently to be able to response to those actions(events).Therefore, a VISUAL BASIC Program is made up of many subprograms, each has its own program codes, and each can be executed independently and at the same time each can be linked together in one way or another.

The Visual Basic Environment
You can choose to start a new project, open an existing project or select a list of recently opened programs. A project is a collection of files that make up your application. There are various types of applications we could create, however, we shall concentrate on creating Standard EXE programs(EXE means executable program). Now, click on the Standard EXE icon to go into the actual VB programming environment.
The Blank Form window which you can design your application's interface.
The Project window displays the files that are created in your application.
The Properties window which displays the properties of various controls and objects that are created in your applications.
It also includes a Toolbox that consists of all the controls essential for developing a VB Application. Controls are tools such as boxes, buttons, labels and other objects draw on a form to get input or display output. They also add visual appeal.
Well, for the next part or lesson you have to wait, as i have to see if i can show / attach some images of VB to make the example programs more clear and understandable.
