3. COM Principles:
Rigorous Encapsulation: - no leakage of implementation details; – All object manipulation through strict
interfaces.
Polymorphism: – via multiple interfaces per class; – “Discoverable”: Query Interface
COM Model – how the techogy is used.
COM ORB = COM Runtime – how is it implemented.
COM is efficianet and scalable: 28 bytes headers; keep-alive messages.
ActiveX: marketing name for a set of technologies and services, all based on COM(model,orb)
Active components - controls: COM-component with designed time, optimized for download and execute; self-
registering; support in multiple languages.
OLE:1.0 – object and container (server/client); object application runs in own window. 2.0 – visual editing,COM
based, controls = *.ocx files.
