Visual Basic (VB) is an object-oriented programming language introduced by Microsoft in 1991. It was designed to enable rapid application development (RAD) of graphical-user interface-based (GUI-based) applications and access to local and remote databases. VB provides a graphical user interface (GUI) that allows programmers to modify code by simply dragging and dropping objects. It is a complete programming language that contains ordinary features such as string processing and computation. VB is a powerful tool for back-end programming and is often used to build internal systems, web and system applications, and even chatbots. VB is also used to program Microsoft Office apps such as Excel and PowerPoint. VB is flexible and can be used to create customized applications that run in Windows or web applications. VB is still used extensively by the programming community because of its rapid application development feature, which allows programmers to build better programs than those developed through other programming languages.
