CObject is the principal base class for the Microsoft
Foundation Class Library. It serves as the root not only for
library classes such as CFile and CObList, but also for the
classes that you write. CObject provides basic services,
including
Serialization support
Run-time class information
Object diagnostic output
Compatibility with collection classes

You can choose from four levels of functionality when
deriving a class from CObject:
• Basic functionality: No support for run-time class
information or serialization but includes diagnostic memory
management.
• Basic functionality plus support for run-time class
information.
• Basic functionality plus support for run-time class
information and dynamic creation.
• Basic functionality plus support for run-time class
information, dynamic creation, and serialization

1. CObjct does support run time VTable.
because it should support IUnknown Interface.
2. The derived base class should not contain early binding
VTbale.
3. Should no over ride the CObject functions.
4. no pure virtual functions should not be declared.
A part from this CObject support RTTI, Debuging,
Serialization and Dump functionalites
