whats the activeX control on the webpages?

Answer 1

An ActiveX control is an object that supports a customizable, programmatic interface. Using the methods, events, and properties exposed by a control, Web authors can automate their HTML pages. Examples of ActiveX Controls include text boxes, command buttons, audio players, video players, stock tickers, and so on.

You can develop ActiveX Controls using Microsoft Visual Basic, Microsoft Visual C++, and Java.
