COM and Automation

The driving force behind Automation is the Component Object Model (COM), which determines the rules for creating objects by the server application and specifies the methods that both the server and the control application must apply when using these objects. The COM standard contains a collection of functions that are made available as Automation interfaces.

When a server application creates an object, it automatically makes available an interface that goes along with it. This interface includes properties, methods, and events that can be recognized by the object. The controller application doesn't need to know the internal structure of the object in order to control it. It only needs to know how to manipulate the object interface that is made available by the server application.
