Visual Basic for Applications

​Visual Basic for Applications (VBA) is an implementation of Microsoft's event-driven programming language Visual Basic 6, which was declared legacy in 2008, and is an associated integrated development environment (IDE). Although pre-.NET Visual Basic is no longer supported or updated by Microsoft, the VBA programming language was upgraded in 2010 with the introduction of Visual Basic for Applications 7 in Microsoft Office applications.[1] As of 2020, VBA has held its position as "most dreaded" language for developers for 2 years, according to some who participated in surveys undertaken by Stack Overflow. (The most dreaded language for 2018 was Visual Basic 6).[2]

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.

As its name suggests, VBA is closely related to Visual Basic and uses the Visual Basic Runtime Library. However, VBA code normally can only run within a host application, rather than as a standalone program. VBA can, however, control one application from another using OLE Automation. For example, VBA can automatically create a Microsoft Word report from Microsoft Excel data that Excel collects automatically from polled sensors. VBA can use, but not create, ActiveX/COM DLLs, and later versions add support for class modules.

VBA is built into most Microsoft Office applications, including Office for Mac OS X (except version 2008), and other Microsoft applications, including Microsoft MapPoint and Microsoft Visio. VBA is also implemented, at least partially, in applications published by companies other than Microsoft, including ArcGIS, AutoCAD, CorelDraw, LibreOffice, Reflection,[3] SolidWorks,[4] WordPerfect, and UNICOM System Architect (which supports VBA 7.1).

​Corby is a town and borough in the county of Northamptonshire, England.

It is located 23 miles (37 km) north-east of the county town, Northampton. At the 2011 Census the town had a population of 54,927[1] and the borough had a population of 61,255.[2] Figures released in March 2010 revealed that Corby has the fastest growing population in both Northamptonshire and the whole of England. The borough of Corby borders onto the borough of Kettering, the district of East Northamptonshire, the district of Harborough and the unitary authority county of Rutland. The town was at one time known locally as "Little Scotland" due to the large number of Scottish workers who came to Corby for its steelworks. Recently, Corby has undergone a large regeneration process with the opening of Corby railway station and Corby International Pool in 2009 and the Corby Cube building opening in 2010. This is home to Corby Borough Council offices and also houses a 450-seat theatre, a public library and other community amenities.
