What happens when client calls CoCreateInstance?

Answer Posted / 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.
