History of Visual Basic

Microsoft Visual Basic (often abbreviated as VB only) is a programming language that is event driven and offer Integrated Development Environment (IDE) to create visual-based application program Microsoft Windows operating systems using programming models Common Object Model (COM). Visual Basic is a derivative of BASIC language and the development offers a graphical computer applications quickly, access to databases using Data Access Objects (DAO), Remote Data Objects (RDO), or ActiveX Data Objects (ADO), and offers an ActiveX control creation and object ActiveX. Some scripting languages such as Visual Basic for Applications (VBA) and Visual Basic Scripting Edition (VBScript), similar as Visual Basic, but the way it works differently.

The programmer can build applications using components provided by Microsoft Visual Basic programs written in Visual Basic can also use the Windows API, but requires an additional external function declarations.

In business programming, Visual Basic has a market share of very large. In a survey conducted in 2005, 62% reported software developers use various forms of Visual Basic, which was followed by C + +, JavaScript, C #, and Java.


History

Bill Gates, founder of Microsoft, started the business by developing software Basic language interpreter for the Altair 8800, for then he changed to run on the IBM PC with DOS operating system. The next development is the launch of BASICA (basic-advanced) for DOS. After BASICA, Microsoft launched the Microsoft QuickBASIC, and Microsoft Basic (also known as Basic Compiler).

History in the hands of Microsoft BASIC as the language that is interpreted (BASICA) and also a compiled language (Bascom) to Visual Basic is implemented as a combination of both.

Programmers who use Visual Basic can choose the compiled code or code should be interpreted as a result of the executable from VB code. Unfortunately, despite already compiled a machine language, DLL named MSVBVMxx.DLL still needed. But the characteristics of the compiled language still appear (it is faster than if we use terinterpretasi mode).
