Introduction To Visual Basic 6

by 10:30 0 comments

VISUAL BASIC® is a high level programming language evolved from the earlier DOS version called BASIC. BASIC stands for Beginners' All-purpose Symbolic Instruction Code. The program codes in Visual Basic resemble the English language. Different software companies produce different versions of BASIC, such as Microsoft® QBASIC, QUICKBASIC, GWBASIC, and IBM BASICA and so on.

Visual Basic is a fairly easy programming language and it is for anybody who is interested in programming but lacks professional training in software engineering.  Learning VISUAL BASIC will help young children to improve their logical thinking skills and develop their minds. You can choose to program in VISUAL BASIC purely for fun and enjoyment or create more advanced applications such as educational courseware and commercial software.

VISUAL BASIC is a visual and events driven programming Language. These are the main divergences from the old BASIC. In BASIC, programming is done in a text-based environment and the program is executed sequentially. In VISUAL BASIC, programming is done in a graphical environment. In old BASIC, you have to write a text-based procedure to design the interface, but Visual Basic enables you to design the interface by dragging and resizing the objects as well as changing their colors, just like any windows-based programs.

Visual Basic is event-driven 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). Examples of events are clicking acommand button, entering text into a text box, selecting an item in a list box etc. Therefore, a VISUAL BASIC Program is made up of many subprograms, each with its own program code which can be executed independently and at the same time can be linked together in one
way or another.
