== Introduction ==
'''Visual Basic''' (VB) is a [[programming language]] and integrated development environment (IDE) from [[Microsoft]]. Originating from the earlier [[BASIC]] language, it was first released in 1991 and became widely used for rapid application development of Windows graphical user interface (GUI) programs. The language is event-driven and features a drag-and-drop designer for building user interfaces. The classic version, often called Visual Basic 6 (VB6), was succeeded by [[Visual Basic .NET]] (VB.NET) in 2002, which runs on the [[.NET Framework]].

== History ==
Microsoft introduced Visual Basic 1.0 in 1991 as a successor to the earlier QuickBASIC and BASIC Professional Development System. It combined a visual form designer with the BASIC language, enabling developers to create Windows applications quickly. Version 2.0 (1992) added improved database support, and version 3.0 (1993) introduced the [[Microsoft Jet Database Engine]] and [[ODBC]] support. Visual Basic 4.0 (1995) added support for [[ActiveX]] controls and 32-bit development for Windows 95. Visual Basic 5.0 (1997) introduced the ability to create ActiveX controls and native code compilation. The final classic release, Visual Basic 6.0 (1998), included enhancements to the IDE, web development with [[ASP]], and improved database connectivity. Microsoft ended mainstream support for VB6 in 2008, though the runtime remains available on Windows.

== Features ==
Visual Basic is an event-driven language: code is triggered by user actions or system events. Its IDE provided a graphical designer for placing controls (buttons, text boxes, etc.) onto forms, and a code editor with IntelliSense. The language supports early and late binding, COM components, and a large library of built-in functions. VB6 applications could be compiled to native code or interpreted p-code. The language's syntax is similar to English, making it accessible to beginners. Criticism included lack of inheritance (in classic VB) and limited multithreading support.

== Legacy and Successor ==
Classic Visual Basic's influence is seen in many modern rapid-application-development tools. Its successor, [[Visual Basic .NET]], is a fully object-oriented language that shares syntax but differs significantly under the hood. Many businesses still maintain VB6 applications, and the VB6 runtime is included in some versions of Windows. The language is often cited as a early gateway for non-professional programmers to create functional Windows software.
