ActiveX is Microsoft technology used for developing reusable Object Oriented software Components . ActiveX is an alternate name for OLE Automation (OLE - Object Linking and Embedding), not a separate technology. While the term "Automation" refers to the overall technology, "ActiveX" refers to the objects that can be created and manipulated using Automation. Due to Internet Explorer and Visual Basic's popularity in the late 1990s, many people incorrectly assume that all of ActiveX is related to ActiveX Control s. An ActiveX control is a special type of ActiveX object that is designed to be used similar to a Plugin . The most common use of ActiveX controls is to build plugins for Internet Explorer . TECHNOLOGIES USING ACTIVEX Microsoft has developed a large number of products and software platforms using ActiveX objects, and many are still in use today.
An ActiveX control is similar to a Java Applet . Unlike Java applets, however, ActiveX controls have full access to the Windows operating system. This gives them much more power than Java applets, but with this power comes a certain risk that the ActiveX control may damage software or data on your machine. To control this risk, Microsoft developed a registration system so that browsers can identify and authenticate an ActiveX control before downloading it. Another difference between Java applets and ActiveX controls is that Java applets can be written to run on all platforms, whereas ActiveX controls are currently limited to Windows environments. ActiveX controls can be written in MFC , ATL , C++ and Visual Basic . CONFUSION WITH OTHER TECHNOLOGIES In the late 1990s Microsoft began to reuse the term "Active" in a large number of their technologies. The following technologies are unrelated to ActiveX itself, but have similar naming: SEE ALSO |
