Are there any good sites for learning C++/COM from the ground up? I'm looking for something like a crash course with perhaps two weeks' worth of content.
The course can assume knowledge in standard C/C++, or at least not a complete dummy.
Answer
Since you're asking for websites, you can try this introduction to COM on The Code Project, and how to handle COM in plain C and in C++ on the same site. And of course, you have MSDN.
