  Program that a programmer has to design and write every single step to do a certain task or solve a particular problem. The written program is sequential, its execution is on a line-by-line basis.
• Object-oriented high-level languages


  Makes it simple to program application in Windows by focusing on objects and events.
• Visual Basic


  It is an example of 3GL. It is based on the basic language and provides a graphical programming event in developing user interface.
• Visual Basic 1.0 was first introduced and released by Microsoft. Its syntax is quite similar to the original BASIC program.


  1991
• Visual Basic 2.0 was released. It has increased speed and easier usage environment for programming.


  1992
• Visual Basic 3.0 was released. It became widely used for custom-made programs for business applications.


  Mid-1993
• Visual Basic 4.0 was released. It is capable of creating 16- and 32-bit windows program.


  August 1995
• Visual Basic 5.0 was released. It has introduced the ability to create custom user control as a purely 32-bit version.


  February 1997
• Visual Basic 6.0 was introduced. It is considered as the most powerful and most stable.

  1998
• Visual Basic 2010

  It is classified as a RAD system tool created by Microsoft to be an integrated development environment for software development.
