***What is Visual basic ***
Introduction to Visual Basic:= Visual basic is a BASIC language was first invented in 1971 and it became very popular.
It is still taught as begineer's language.
Visual Basic is now 32 - bit version of the language.
Visual Basic is not just a language but it is an integrated development environment (IDE) in which you can develop, run, test and debug your applications .
Visual Basic allows you to develop Graphical User Interface (GUI) applications. These applications are more user friendly.
Visual Basic is event driven. The code in Visual Basic remains idle until event is detected.
The event can be pressing a button or menu selection. Once the event is detected, the code corrosponding to that event is executed.
Some Features of Visual Basic are:
