  Visual Basic: • Itwas developed in 1992 by a Microsoft company. • VB is a tool that allows you to develop windows(GUI-Graphical user Interface) applications. • VB consists of two parts: Visual Part: This part refers to the method used to create GUI. Basic Part : This part refers to the basic language. VB is the much-enhanced versions of the Basic programming language. VB contains large numbers of statements, built in function and keywords, many of which related directly to the windows GUI. • VB is an object-oriented programming development system for creating applications for Microsoft windows.

  VB • VB hastwo components: An extensive collection of prewritten tools called controls in the form of icons. Some example of controls are command buttons, textboxes , option buttons , check boxes etc. A complete set of program commands, drived from basic programming language.

  Features of VB: Featuresof visual basics are: • Easy to learn and use : The syntaxes of VB commands are so simple that you can use the commands very easily. It is useful for most general-purpose programming problems. • Build in capability to create User Interface : VB has built in capability to create the user interface. You can create the user interface by using the tools available with VB. • Quick Development : As VB has a built-in capability to design the user interface so obviously the programming time is reduced as compared to other command line programming languages. • Event driven Programming: VB supports event driven programming. • Common Programming Platform: It provides a common programming platform across all MS-Office applications. • Wizards: It also provides many wizards that can automate tasks are even automate coding.
