In my daily work, I have seen many COM codes written by different developers. I was amazed by the many creative ways of working with COM, and some of the clever code that made COM work might not even have occurred to Microsoft. Also, seeing some mistakes repeated again and again made me frustrated. Many of these errors are related to thread and security, and this is exactly the two areas that are missing from COM documentation. If you do not plan carefully, they are also the most likely to encou
