COM

COM (Component Object Model) is a Microsoft technology for creating reusable software components that can interact across different programming languages and processes. It enables binary interoperability, allowing components written in various languages (like C++, Visual Basic, or Delphi) to communicate through defined interfaces. COM is foundational for Windows development, supporting features like OLE (Object Linking and Embedding), ActiveX, and DirectX.

🧊Why learn COM?

Developers should learn COM when working on legacy Windows applications, system-level programming, or integrating with Microsoft technologies like Office automation or Internet Explorer. It's essential for maintaining or extending older Windows software, building COM-based APIs, or understanding low-level component architecture in Windows environments. Use cases include creating add-ins for applications like Excel, implementing shell extensions, or developing drivers that rely on COM interfaces.
