COM Objects and Interfaces

COM is a technology that allows objects to interact across process and computer boundaries as easily as within a single process. COM enables this by specifying that the only way to manipulate the data associated with an object is through an interface on the object. When this term is used in this documentation, it refers to an implementation in code of a COM binary-compliant interface that is associated with an object.

 Referring to an object implementing an interface means that the object uses code that implements each method of the interface and provides COM binary-compliant pointers to those functions to the COM library. COM then makes those functions available to any client who asks for a pointer to the interface, whether the client is inside or outside of the process that implements those functions.
