What is ActiveX
ActiveX – is a technology of creating active web pages. This technology is implemented with the ActiveX control element—a dedicated program, for which the browser allocates an area of rectangular form, where this program is completely responsible for the interface with the user. The ActiveX technology supports fully automated installation. When the browser encounters an HTML link to the control element, it first checks if this element is already on the user’s computer (i.e. if it was used before). If the control element is found, the browser starts it and transfers the data necessary for operation to it. If this component is not already available on the computer, the browser accesses the web address specified in the HTML document body, then downloads, installs, and registers the new control element with Windows. This technology is rigidly bound to the specific operational environment of Windows 9x/NT.
