Client Involes
|
CoCreateInstance(IID_IMyInterface)
|
DLLGetClassOject() - This is there in server DLL
|
CoGetClassObject(IID_IClassFactory) - this will return
IClassFactory Interface Pointer. Then call to
IClassFactory->CreateInstace() here we are instatiating the
our class and returning the IMyInterface pointer to client.

Answer / guest
- Reads Root\Classes\ProgId for the matching ProgID
- Reads Root\Classes\ProgId for the matching CLSID. The
CLSID is read from the above step.
- From the CLSID key, the server type and image filename is
known.
- Depending upon the server type, it starts the server.
- Calls CoGetClassObject function to get a handle to the
factory object.
- Then calls createinstance on the factory interface to get
the pointer to the derived object.
