The greatest "inventions" of Microsoft last ten years may be a COM (Component Object Model).
I have been using .NET to do Windows development, although the operation of the .NET assembly is much more than the COM operation, and .NET can also be interoperable with the original COM. According to reason, can not Learn COM technology. But think about it as a computer professional undergraduate, you should know more technical details, and COM has a huge role in code reuse, so COM is to learn.
There is also recently I want to do an ActiveX on your own website to facilitate the use of the old customers who often use the website service to skip access to the tedge. Therefore, it also constitutes a reason to learn COM, because COM is the cornerstone of ActiveX technology.
Said ActiveX, I remembered the mechanism of the client JavaScript callback server-side method in ASP.NET 2.0, which used XMLHTTP, which is an ActiveX. So this seems regardless of how COM technology will continue to have a cross-language cross-platform and provide binary-scale compatible standards in this technology noun and a day increasing era.
This should be the sentence: the times are changing, good things are constant.
