c++ - ATL类与一般的类继承有什么区别

Question

各有什么优劣

Answer 1

This is such a big problem. Essentially there is no difference, it is just C++ class inheritance. However, ATL's template design was so exquisite that the later C++ standard library also learned from it.

I have only read books about COM and have not practiced it. After all, there are very few opportunities to use it now. If someone tells you a detailed answer, you may be able to fully understand it. You are still familiar with the principles of COM. If you read the ATL book, you should understand it.
