Visual Basic is a high-level programming language, which was developed from previous versions of DOS called Basic. BASIC means beginners' All-purpose Symbolic instruction code. It is a very simple programming language to learn. At looks very much like the English language. Various software produced different versions of the basic, such as Microsoft QBASIC, QUICKBASIC, GWBASIC, IBM BASICA and so on. But it seems people are only using Microsoft Visual Basic today, as it is a well-developed programming and support resources are available everywhere.

With Visual Basic, you can almost program depending on your goals. For example, you can program the software to teach science, mathematics, language, history, geography and so on. You can also program of financial and accounting software to give you a more effective accounting or finance. For those of you who want to play, you can program that so well. In fact there is no limit to what you can program! There are many such programs in this tutorial, so you have to spend more time on the self that is used in the majority.

Visual Basic is a visual programming language-driven events. These are the main differences from the old BASIC. In basic research, programming will be made in the Text-Only the environment and the program is executed sequentially. In Visual Basic, programming is done in a graphical environment. In the old BASIC, you need to write a program code for each graphic object, you want to view the display, including its position and its color. But in Visual Basic, simply drag and drop a graphic object anywhere on the form, and you can change its color all the time through the windows of buildings.

On the other hand, because users can click on a particular object by chance, so that each facility must be independently programmed to respond to these actions (events). Therefore, Visual Basic program consists of many subprograms, each with its own program codes, and each can be implemented independently and at the same time, each can be connected in one way or another
