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).
Dronfield is a town in North East Derbyshire, England, which includes Dronfield Woodhouse and Coal Aston. It lies in the valley of the River Drone between Chesterfield and Sheffield. The Peak District National Park is three miles (4.8 km) to the west. The name means open land infested with drones (male bees).
The town existed before the 1086 Domesday Book, and has a 13th-century parish church. In 1662, Charles II granted the town a market, although this later ceased. The industrial history of the town includes coal mining, the wool trade, the production of soap and steel, and engineering. Today a range of manufacturing firms still operate in the town.
Dronfield's population increased dramatically in the post-war years from 6,500 in 1945 to its current size of just over 21,000.[1]
The football ground to the north of the town is currently the home of Sheffield F.C., the world's oldest football club.
