I'm new to COM, and I don't know what it is or why it exists.
Is this a programming methodology like OOP? Do programming languages have to support it? (with some special keywords or something)
When I asked my professor about it, he said:
COM is a binary-stable way to do OOP. We need to know binary-layout (something..something..)
I've no idea what it means. Some people say it is used for code reuse. OOP does a good job at that already, so then why did this COM evolve in the first place?
What is it with C++ and COM? Wherever I see COM, it's is always described with abstract C++ examples. Is it only for C++?
Can any one show me a case or exmaple so that I can understand the need for COM? What are the requirements for learning this, so I can write my own components?
