Microsoft introduced ActiveX in 1996. In principle, ActiveX is not dependent on Microsoft Windows operating systems, but in practice, most ActiveX controls only run on Windows. Most also require the client to be running on an x86-based computer because ActiveX controls contain compiled code. [2]
Active Scripting (formerly known as ActiveX Scripting) is the technology used in Windows to implement component-based scripting support. It is based on OLE Automation (part of COM ) and allows installation of additional scripting engines in the form of COM modules.
Later versions of Internet Explorer prompt the user before installing an ActiveX control, allowing them to block installation. As a level of protection, an ActiveX control is signed with a digital signature to guarantee authenticity. It is also possible to disable ActiveX controls altogether, or to allow only a selected few.
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.
Microsoft Access may also be part of a more complex solution, where it may be integrated with other technologies such as Microsoft Excel, Microsoft Outlook, Microsoft Word, Microsoft PowerPoint and ActiveX controls. Access tables support a variety of standard field types, indices, and referential integrity including cascading updates and deletes.
ActiveX was based on a number of technologies Microsoft had already developed for Windows. ActiveX controls were OLE based controls that could be embedded in web pages, applications, and on the desktop. ActiveX became strongly criticized for security problems, and Microsoft later abandoned further development in favor of the .NET Framework.
