Visual Basic for Applications (VBA) is an implementation of Microsoft’s event-driven programming language Visual Basic 6, which was discontinued in 2008, and its associated integrated development environment (IDE). Although Visual Basic is no longer supported or updated by Microsoft, VBA itself got upgraded in 2010 with the introduction of Visual Basic for Applications 7 in Microsoft Office applications.
Visual Basic for Applications enables building user-defined functions (UDFs), automating processes and accessing Windows API and other low-level functionality through dynamic-link libraries (DLLs). It supersedes and expands on the abilities of earlier application-specific macro programming languages such as Word’s WordBasic. It can be used to control many aspects of the host application, including manipulating user interface features, such as menus and toolbars, and working with custom user forms or dialog boxes.
