IMPLEMENT_DYNAMIC,IMPLEMENT_SERIAL & IMPLEMENT_DYNCREATE macros internals?

[ledallam]

Hi, I would like to know the role of IMPLEMENT_DYNAMIC,IMPLEMENT_SERIAL & IMPLEMENT_DYNCREATE macros in mFC. I very well know that they are used for Dynamic Creation of objects,Accessing runtime information and for Serialization. But I want to know how these macros help in this? Can anyone please give me some link to articles where I can find this information. Thanks Madhavi.
