Activex control is a ready to use control.....
In our system there will be some inbuilt active x controls 
given by the os, such as...windows media player ,calender 
etc...thease controls can be used in any platform
(c ,c++,java,dotnet....).So we can also create the active x 
controls that can be used anywhere in any 
application...using actrive x controls in vc++ is very easy

ActiveX are software component based on Microsoft's 
component based technology(COM).ActiveX controls were 
originally called "OLE controls" and used an .OCX file 
extension. They were Microsoft's second-generation 
component architecture (Visual Basic Controls (VBXs) were 
the first). OLE controls were renamed ActiveX and continued 
to use the .OCX name.

A Microsoft ActiveX control is essentially a simple OLE 
object that supports the IUnknown interface. 
Developed by Microsoft corporation, ActiveX is a technology 
used to add interactivity to Web pages. With ActiveX, you 
can add interactive controls to Web pages. These controls 
can be anything from a single push-button to a complete 
spreadsheet.

An ActiveX interface is a group of related functions that 
are grouped together

A method is an exposed function that can be applied to a 
control via the IDispatch interface.

1.Stock Properties
2.Custom Properties.

For managing these properties, property sheets are used.

ActiveX controls have four types of properties:
l Stock:-> These are standard properties supplied to every 
control, such as font or
color. The developer must activate stock properties, but 
there is little or no
coding involved.

2 Ambient:-> These are properties of the environment that 
surrounds the control -
properties of the container into which it has been placed. 
These can't be changed,
but the control can use them to adjust its own properties. 
For example, it can set
the control's background color to match the container's 
background color.

3 Extended:-> These are properties that the container 
handles, usually involving size
and placement onscreen.

4 Custom:-> These are properties added by the control 
developer.

This comes at the comiplization time, If we give the LOGO
option to the compiler, it take a bitmap file (i.e, ) as
logo before loading the Application.

We can customize these objects by saving into image
