推荐答案

CoCreateInstance 是COM库中的辅助函数，它定位您所关注对象的classfactory（通过CLSID或PROGID）并调用其 IClassFactory :: CreateInstance 方法



因此，在实践中它们是相同的东西

CoCreateInstance is the helper function in the COM libraries, that locates the classfactory for the object you're after (by CLSID or PROGID) and invokes its IClassFactory::CreateInstance method

So, in practice they're the same thing
