Introduction of VB

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 use - 

  • Data Access Objects
  • Remote Data Objects
  • ActiveX Data Objects

History of VB     
VB 1.0 was introduced in 1991, developed by Alan Cooper and his company called Tripod. Microsoft contracted with Cooper and his associates to develop Tripod into a programmable 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 successor was Visual Basic .NET (now known simply as Visual Basic)

  • Sequential and random access file support.
  • Useful debugger and error-handling facilities.
  • Powerful database access tools.

Advantage of VB

  • VB is not only a language but primarily an integrated, interactive development environment.
  • 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 application.
  • VB provides a comprehensive interactive and context-sensitive online help system.
  • COM components can be written in different languages and then integrated using VB.
  • 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 purposes.

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.
