Chapter 29. Internet Security > Restricting ActiveX Controls

Restricting ActiveX Controls

One of the most talked about features of Internet Explorer 5.0 is its support for ActiveX controls. ActiveX technology, an extension of what was known in previous versions of Windows as object linking and embedding (OLE), commonly refers to component software used across networks, including the Internet. Internet Explorer 5.0 uses ActiveX components in the browser window to display content that ordinary Hypertext Markup Language (HTML) can't handle, such as stock tickers, cascading menus, or Adobe Acrobat documents. An ActiveX chart control, for example, can take a few bits of data from a distant server and draw a chart at the speed of the local PC, instead of forcing you to wait while downloading a huge image file. The Microsoft Investor page (see Figure 29.13) offers a particularly rich example of this capability to quickly gather and manipulate data.

Figure 29.13. An ActiveX control on this page makes it possible to quickly analyze and display complex data such as stock prices.
