Editor to share with you what the activex control means, I believe most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

ActiveX controls refer to "plug-ins", small programs for the Internet; they allow you to play animations or help with tasks such as installing security updates on Microsoft Update, thus enhancing your browsing experience.

The operating environment of this tutorial: windows10 system, Dell G3 computer.

What is the activex control?

Activex is Microsoft's term for a series of strategic object-oriented programming technologies and tools, the main of which is component object Model (COM). In networks with directories and other support, COM becomes distributed COM (DCOM).

ActiveX controls are small programs, sometimes called plug-ins, that are used on the Internet. They allow you to play animations or help with tasks such as installing security updates on Microsoft Update, thus enhancing your browsing experience.

When creating programs that include ActiveX, the main job is components, a self-sufficient program that can run freely on ActiveX networks (today's networks mainly include Windows and Mac). This component is the ActiveX control. ActiveX is proposed by Microsoft to counteract the JAVA technology of Sun Microsystems, and the function of this control is similar to that of java applet.

If you are using the Windows operating system, you may notice some files that end in OCX. OCX stands for "object linking and embedded controls" (OLE), a programming technology proposed by Microsoft to deal with the mixed use of desktop files. Now that the concept of COM has replaced part of OLE, Microsoft also uses ActiveX controls to represent component objects.

One of the great advantages of components is that they can be reused by most applications (which are called component containers). A COM component (ActiveX control) can be developed by development tools in different languages, including C++ and Visual Basic or PowerBuilder, or even some technical languages such as VBScript.

Currently, the ActiveX control runs in Windows 95/NT and Macintosh, and Microsoft is also ready to support UNIX's ActiveX control.

Classification of activex control components

1. Automation server: components that can be programmatically driven by other applications. The automation server includes at least one, perhaps multiple, IDispatch-based interfaces for other applications to generate and connect. The automation server may or may not have a user interface (UI), depending on the features and functionality of the server.

2. Automation controllers: applications that use and manipulate automation servers.

3. Controls: ActiveX controls are equivalent to previous OLE controls or OCX. A typical control includes a design-time and run-time user interface, a unique IDispatch interface that defines the control's methods and properties, and a unique IConnectionPoint interface for events that can be raised by the control.

4. Documents: ActiveX documents, known as DocObject, represent an object that is not just a simple control or an automated server. ActiveX documents are structured extensions to OLE links and models and have more control over the containers in which they are located. One of the most significant changes is the way menus are displayed. The menu of a typical OLE document will be merged with the container menu to form a new collection, while the ActiveX document will replace the entire menu system, showing only the characteristics of the document rather than the common characteristics of the document and the container.

Container: the ActiveX container is an application that can host automation servers, controls, and documents.

Activex control application

The ActiveX control is a reusable software component. By using the ActiveX control, you can quickly add special functions to web addresses, desktop applications, and development tools. For example, StockTicker controls can be used to instantly add activity information to a web page, and animation controls can be used to add animation features to a web page. Today, there are more than 1000 commercial ActiveX controls, which can be developed in a variety of programming languages, such as Microsoft Visual Basic ®, the next generation of Microsoft Visual Basic controls, and Microsoft's Visual Java development environment Microsoft Visual Jacks + ™. The main editing language is as follows: the main editing language is: the main editing language is the Centralizable Magi VBMagneVB Magi VBScript, the Java Personnal Delphi Grader PowerBuilderMagi VBScript. Once the ActiveX control is developed, designers and developers can use it as a pre-assembled component for developing client programs. Using ActiveX controls in this way, users do not need to know how these components are developed, and in many cases, they can complete the design of a web page or application without even programming themselves.

ActiveX controls can be used on Windows forms and Web programs, so no matter what language applications are developed as long as they are used in windows forms and html pages, as well as in MAC and JAVA platforms, most of them use ActiveX controls. This is what we usually see in a variety of online banking security controls and other applications.
