Overview
The Microsoft Windows ActiveX technology allows objects called 'components'
to be developed, and are used by inserting them into an ActiveX container, like

which can be graphical or non-graphical, but they follow standard rules for
defining their Properties, Methods and Events. Properties are like settings, for
example a control's colour would be a property. Methods are like functions or
actions that can be called for example a control might support a Redraw
method. Events are actions the control may create, like OnLeftClick. Following
these standard rules allows any ActiveX control from any manufacturer to
work in any container.
