The term "ActiveX" refers to a technology developed by Microsoft for reusing software components across various programs and applications. ActiveX components, also known as ActiveX Controls, enable the integration of interactive or functional elements—such as media content, form functionality, or data connections—primarily within web browsers (especially Internet Explorer) and Microsoft applications like Excel or Access. Based on COM (Component Object Model), ActiveX is mainly used in Windows environments.
Embedding external components: Using predefined controls like calendars, list boxes, or buttons in software applications.
Automation of Office applications: Controlling Microsoft Excel, Word, or Outlook via embedded ActiveX controls.
Media integration: Embedding multimedia content (e.g., audio and video players) into web or desktop applications.
Database access: Integrating ActiveX components for connecting to databases (e.g., via ADO – ActiveX Data Objects).
Custom forms and dialog boxes: Creating interactive user interfaces with event-driven ActiveX controls.
Security and permissions: Managing access rights for embedded components to minimize potential risks.
