Licclien: Client of Licensed DLL Server
Note To use this sample, you must first build the Licserve sample.
The Licclien sample examines how a client application uses licensed components provided by a COM server. Licclien works with the COM servers of two other samples, Licserve and Dllserve. It manipulates a set of components similar to those presented in Dllclien: COCar, COUtilityCar, COLicCruiseCar, and COUtilityCruiseCar. In this lesson, the COCar and COUtilityCar components are obtained, as they were in Dllclien, from the Dllserve server. This sample, however, uses a new licensed version of the COCruiseCar component that is presented in Dllserve and Dllclien. This licensed component, COLicCruiseCar, is housed in a different server, Licserve.
Like Dllclien, Licclien.exe creates its own COUtilityCruiseCar COM object, which is constructed by reusing the licensed COLicCruiseCar COM object by aggregation and augmenting it with a native IUtility interface. Because the COLicCruiseCar COM object class is a licensed aggregatable component, Licclien illustrates nested aggregation involving a licensed component.
