Overview

This course provides a complete, hands‑on introduction to C++ component development using COM and ATL 3.0. You’ll learn how to build COM objects, COM servers, ActiveX controls, dual interfaces, Automation clients, event‑driven COM components, threading models, and reusable COM architectures such as containment and aggregation.

Built on Microsoft‑aligned curriculum, this course is ideal for C++ developers working with legacy COM/ATL systems, integration layers, or maintaining enterprise applications built on COM‑based architectures.
