Whenyou open a file that has ActiveX controls, the yellow Message Bar appears with a shield icon and the Enable Content button. If you know the controls are from a reliable source, use the following instructions:

Prompt me before enabling Unsafe for Initialization (UFI) controls with additional restrictions and Safe for Initialization (SFI) controls with minimal restrictions There are two behaviors based on the presence of VBA projects:

Without a VBA project SFI ActiveX controls are enabled with minimal restrictions and the Message Bar does not appear. However, ActiveX controls must all be marked as SFI to not to generate the Message Bar. UFI ActiveX controls are disabled. However, when a user enables the UFI controls they are initialized with additional restrictions (e.g. default values). Any persisted data that is part of the UFI control will be lost.

ActiveX controls are small building blocks that create applications that work over the Internet through Web browsers. Examples include customized applications for collecting data, viewing certain kinds of files, and displaying animation. Common uses of ActiveX controls are command buttons, list boxes, and dialog boxes. Office programs also let you use ActiveX controls to improve some documents.

ActiveX controls can have unrestricted access to your computer and therefore can access your local file system and change your operating system registry settings. If a hacker uses an ActiveX control to take over your computer, the damage can be significant.

Many user's computers by default won't trust ActiveX, and it will be disabled; this sometimes needs to be manually added to the trust center. ActiveX is a microsoft-based technology and, as far as I'm aware, is not supported on the Mac. This is something you'll have to also consider, should you (or anyone you provide a workbook to) decide to use it on a Mac.

One major difference that is important to know is that ActiveX controls show up as objects that you can use in your code- try inserting an ActiveX control into a worksheet, bring up the VBA editor (ALT + F11) and you will be able to access the control programatically. You can't do this with form controls (macros must instead be explicitly assigned to each control), but form controls are a little easier to use. If you are just doing something simple, it doesn't matter which you use but for more advanced scripts ActiveX has better possibilities.

ActiveX controls are component program objects that Microsoft developed to enable applications to perform specific functions, such as displaying a calendar or playing a video. An ActiveX control is a small program that other applications can reuse to enable the same functionality, without the extra development work.

These controls typically have been implemented as plugins to enhance various types of Internet Explorer (IE) web applications. For example, a manufacturing firm might build a web application to track product inventory and provide managers with updated details about the inventory. To support this functionality, the application could include an ActiveX control that gives users reports on inventory levels and trends. When the users first visit the webpage through IE, they're prompted to install the ActiveX control, which the application then uses to deliver the reports.

Microsoft has said it will retire Internet Explorer in June 2022 and move to the Microsoft Edge web browser. Edge does not support ActiveX controls, but it does include IE mode, which enables users to access legacy IE applications through Edge. With IE mode, applications can continue to use ActiveX controls, as long as a user's system is configured to permit their use.

In addition to web applications, other types of Windows applications -- such as Microsoft Word and Excel -- can use ActiveX controls. For instance, a developer might add an ActiveX control to a Word document that lets users fill out a form in the document. By using ActiveX controls, developers can implement commonly performed operations across many applications without having to redevelop the code for each instance.

ActiveX controls are supported in other ways. One example is the Google Chrome browser, which offers the IE Tab add-in. This is a Chrome extension that displays webpages using IE. The IE Tab add-in makes it possible to use ActiveX controls within Chrome.

ActiveX controls are part of Microsoft's overall ActiveX technology. These technologies are based on the Component Object Model (COM), an interoperability standard for building reusable software libraries that can interact at runtime. ActiveX controls replaced the earlier Object Linking and Embedding, known as OCX, custom-level controls.

An ActiveX control is roughly equivalent in concept and implementation to the Java applet. Developers can build an ActiveX control in programming languages that work with Microsoft's COM. Visual Basic and C++ are often used to write ActiveX controls.

An ActiveX control is implemented as a dynamic link library module that runs in a container. By using reuseable components, application developers cut the time required for program development and improve the capabilities and quality of their program.

Over the years, ActiveX controls have been implemented to support web applications. However, they aren't used much these days because they pose many security risks. Under the right circumstances, an ActiveX control can gain almost unlimited access to the underlying system and even to network resources, depending on the user's level of access.

ActiveX controls are easy for users to install. All it takes is a few simple clicks, which can make them susceptible to a range of attacks. For example, an organization's users might be the target of a phishing campaign that directs them to a malicious website, where they're prompted to install an ActiveX control. If the phishing campaign is successful, the users will trust the site and install the control with little thought. The ActiveX control might then change passwords, access confidential data, install malware or carry out any number of other operations.

Microsoft has added security protections to safeguard against malicious ActiveX controls, but these were never enough to ensure total protection against possible risks. Even Microsoft states that ActiveX controls "can sometimes malfunction or give you content that you don't want. In some cases, these apps might be used to collect info from your PC, damage info on your PC, install software on your PC without your agreement or let someone else control your PC remotely."

Despite these warnings, ActiveX controls are still in use, and hackers continue to take advantage of their vulnerabilities. As recently as September 2021, Microsoft released a security patch to address a remote code execution vulnerability. An attacker could create a specially crafted Microsoft Office document that hosts the browser rendering engine. When a user opened the document, it launched a malicious ActiveX control, which could then gain access to the underlying system.

Although ActiveX controls continue to be supported, Microsoft considers them a legacy technology. Most of today's browsers either no longer support ActiveX controls or disable them by default. In all likelihood, support for ActiveX controls will eventually disappear.

ActiveX is a deprecated software framework created by Microsoft that adapts its earlier Component Object Model (COM) and Object Linking and Embedding (OLE) technologies for content downloaded from a network, particularly from the World Wide Web.[1] 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]

ActiveX was one of the major technologies used in component-based software engineering.[4] Compared with JavaBeans, ActiveX supports more programming languages, but JavaBeans supports more platforms.[5] ActiveX is supported in many rapid application development technologies, such as Active Template Library, Delphi, JavaBeans, Microsoft Foundation Class Library, Qt, Visual Basic, Windows Forms and wxWidgets, to enable application developers to embed ActiveX controls into their products.

Faced with the complexity of OLE 2.0 and with poor support for COM in MFC, Microsoft simplified the specification and rebranded the technology as ActiveX in 1996.[6][7] Even after simplification, users still required controls to implement about six core interfaces. In response to this complexity, Microsoft produced wizards, ATL base classes, macros and C++ language extensions to make it simpler to write controls.

Starting with Internet Explorer 3.0 (1996), Microsoft added support to host ActiveX controls within HTML content. If the browser encountered a page specifying an ActiveX control via an OBJECT tag (the OBJECT tag was added to the HTML 3.2 specification by Charlie Kindel, the Microsoft representative to the W3C at the time[8]) it would automatically download and install the control with little or no user intervention. This made the web "richer" but provoked objections (since such controls, in practice, ran only on Windows, and separate controls were required for each supported platform: one for Windows 3.1/Windows NT 3.51, one for Windows NT/95, and one for Macintosh M68K/PowerPC.) and security risks (especially given the lack of user intervention). Microsoft subsequently introduced security measures to make browsing including ActiveX safer.[9]

ActiveX was controversial from the start; while Microsoft claimed programming ease and good performance compared to Java applets in its marketing materials, critics of ActiveX were quick to point out security issues and lack of portability, making it impractical for use outside protected intranets.[10] The ActiveX security model relied almost entirely on identifying trusted component developers using a code signing technology called Authenticode. Developers had to register with Verisign (US$20 per year for individuals, $400 for corporations) and sign a contract, promising not to develop malware. Identified code would then run inside the web browser with full permissions, meaning that any bug in the code was a potential security issue; this contrasts with the sandboxing already used in Java at the time.[11]
