- File: FACTORY.CPP
-
- Summary: Implementation file for the Class Factories of the LICSERVE
- server. This server provides a licensed factory for the
- LicCruiseCar COM component. Thus this COM object factory
- implements IClassFactory2. In addition, a non-licensed
- CFLicCarSample class factory is included to provide a
- component with the Code Sample utility interface ISample.
- This interface is primarily for use within the code samples
- for the purposes of setting them up as samples (eg, setting
- up the server so that it trace logs to the client's trace log
- facility). The COM Components that can be manufactured by
- this server are known outside the server by their respective
- CLSIDs: CLSID_LicCruiseCar and CLSID_LicCarSample.
-
- For a comprehensive tutorial code tour of this module's
- contents and offerings see the tutorial LICSERVE.HTM file.
- For more specific technical details on the internal workings
- see the comments dispersed throughout the module's source code.
-
- Classes: CFLicCruiseCar, CFLicCarSample.
-
- Functions: .
-
- Origin: 10-5-95: atrent - Editor-inheritance from FACTORY.CPP in
- the DLLSERVE Tutorial Code Sample.
