VB( Visual Basic) is IDE of Microsoft of third generation event-driven
programming language. Visual Basic is simple and easy to use. Visual Basic was
derived from BASIC and enables the rapid application development (RAD) of
graphical user interface (GUI) applications. For accessing database we can

History of VB
VB 1.0 was introduced in

form system for Windows 3.0. The final release was version 6 in
1998. Microsoft's extended support ended in March 2008 and the designated

Advantage of VB
VB is not only a language but primarily an integrated, interactive
The structure of the Basic programming language is very simple,
particularly as to the executable code.
The VB-IDE has been highly optimized to support rapid application
development ("RAD"). It is particularly easy to develop graphical user
interfaces and to connect them to handler functions provided by the
VB provides a comprehensive interactive and context-sensitive online help
COM components can be written in different languages and then integrated
Interfaces of COM components can be easily called remotely via Distributed
COM ("DCOM"), which makes it easy to construct distributed applications.
There is a wealth of readily available COM components for many different
Disadvantage of VB
The Applications which are developed in VB are working only on Windows
Operating systems only.
More memory space is required to install and work in VB as VB is GUI based
development tool it contains Graphical components that need more space.
You have to install in everywhere . Support only up to a level, no low
level functions and high level functions.
