Visual Basic (VB) is a high-level, event-driven programming language and integrated development environment (IDE) developed by Microsoft. It was first released in 1991 and became immensely popular due to its graphical approach to building applications. Visual Basic allowed developers to easily create a graphical user interface (GUI) by simply dragging and dropping controls like buttons, text boxes, and labels onto a form. The programmer would then write code to define the "events" associated with these controls, such as what happens when a user clicks a button. This approach significantly simplified and accelerated the development of Windows applications.
The original Visual Basic (versions 1.0 through 6.0) was a very common choice for creating custom applications to control laboratory and industrial equipment. While this classic version of Visual Basic is now considered a legacy language, it was succeeded by Visual Basic .NET (VB.NET), which is a modern, object-oriented language that is part of Microsoft's Visual Studio and the .NET framework. Both classic and modern versions of Visual Basic can be used with VISA libraries to create powerful test and measurement applications.
Visual Basic is a programming language included in Visual Studio, an IDE provided by Microsoft Corporation.
