A short description of Visual Basic
Visual Basic is a programming language and an environment (1) (develop) by Microsoft in 1990. It (2) (use) to create applications for Windows operating systems.
The name ‘BASIC’ (3) (stand) for Beginner’s All-purpose Symbolic Instruction Code. The original BASIC language (4) (create) in 1965 and adopted by many programmers and PC manufacturers because it was user-friendly and easy to learn.
The adjective ‘Visual’ refers to the technique used to create a graphical user interface. Instead of (5) (write) a lot of instructions to describe interface elements, you just (6) (add) pre-defined objects such as buttons and dialog boxes, which can (7) (choose) from a toolbox. It (8) (take) only a few minutes to create a Visual BASIC program. Using the mouse, you simply (9) (drag) and drop controls (e.g. option buttons, text boxes, icons, menu bars, etc.) into the required position, and then define their colour, size and behaviour.
Thanks to its object-oriented philosophy and interactive nature, Visual BASIC (10) (enable) the programmer to quickly create all sorts of applications from small system utilities to database programs and Internet server applications.
