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. 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).
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, SolidWorks, WordPerfect, and UNICOM System Architect (which supports VBA 7.1).
Wellingborough (/ˈwɛlɪŋbərə/ WEL-ing-bər-ə) is a large market town in the Wellingborough district of Northamptonshire, England, 11 miles (18 km) from Northampton on the north side of the River Nene.
Originally named "Wendelingburgh" (the stronghold of Wændel's people), the Anglo-Saxon settlement is mentioned in the Domesday Book as "Wendelburie". The town was granted a royal market charter in 1201 by King John.
At the 2011 census, the town had a population of 49,128. The Borough Council of Wellingborough has its offices in the town centre. The town is twinned with Niort in France, and with Wittlich in Germany.
The town is predicted to grow by 30 per cent under the Milton Keynes South Midlands (MKSM) study, and the government has identified Wellingborough as one of several towns in Northamptonshire where growth in jobs and housing will be directed. The area will see an addition of around 10,000 homes by 2031, mainly to the east of the town. Wellingborough, along with Corby and Kettering together comprise the core of the North Northamptonshire growth area, coordinated by the North Northamptonshire Joint Planning and Delivery. The town also has a growing commuter population as it is on the Midland Main Line railway, operated by East Midlands Railway, with trains to London St Pancras International taking under an hour, and an interchange with Eurostar services.
