- APTCLIEN - Client of an apartment model out-of-process local server
-
-
- SUMMARY
- =======
-
- The APTCLIEN sample shows a client of several single-threaded apartments
- in the APTSERVE server. APTCLIEN's main purpose is to exercise and reveal
- for study the multiple apartments in the APTSERVE local out-of-process
- server. The following REMCLIEN sample, run in conjunction with APTCLIEN,
- shows the effects of multiple clients on the APTSERVE multithreaded
- server, with one client controlling from a remote machine.
-
- The COM objects that APTCLIEN manipulates are the car-related ones from
- previous samples in this tutorial series, with the following interfaces:
- ICar, IUtility, and ICruise. APTCLIEN works in conjunction with the
- separate APTSERVE.EXE, which provides the COCar, COUtilityCar, and
- COCruiseCar COM objects.
-
- APTCLIEN.EXE creates its own COUtilityCruiseCar COM object by reusing the
- COCruiseCar COM object by containment and augmenting it with a native
- implementation of the IUtility interface. Like LOCCLIEN, APTCLIEN's
- COUtilityCruiseCar composite object reuses COCruiseCar by containment.
- However, because COCruiseCar and COCar are in different apartments,
- COCruiseCar reuses COCar by containment rather than the aggregation shown
- in previous lessons.
-
- The composition of COUtilityCruiseCar is also interesting because the
- COUtilityCruiseCar object's containment of the COCruiseCar object crosses
- the process boundary between APTCLIEN and the out-of-process local server
- APTSERVE.EXE. In addition, COCruiseCar's containment of COCar crosses
- thread boundaries within APTSERVE. APTCLIEN uses standard marshaling
- support for the custom interfaces it uses on the COCruiseCar and COCar
- objects. This marshaling support is provided by the previous MARSHAL
- code sample, so you must build the MARSHAL code sample prior to building
- and running APTCLIEN and APTSERVE.
-
- For functional descriptions and a tutorial code tour of APTCLIEN, see the
- Code Tour section in APTCLIEN.HTM. For details on the external user
- operation of APTCLIEN, see both the Usage and Operation sections in
- APTCLIEN.HTM. To read APTCLIEN.HTM, run TUTORIAL.EXE in the main tutorial
- directory and click the APTCLIEN lesson in the table of lessons. You can
- also achieve the same thing by clicking the APTCLIEN.HTM file after
- locating the main tutorial directory in the Windows Explorer. See also
- APTSERVE.HTM in the main directory for more details on how APTSERVE works
- and exposes its services to APTCLIEN. You must build APTSERVE.EXE before
- building APTCLIEN. The makefile for APTSERVE automatically registers that
- server in the registry, so you must build APTSERVE before attempting to
- run APTCLIEN.
-
- For details on setting up your system to build and test the code samples
- in this COM Tutorial series, see TUTORIAL.HTM. The supplied MAKEFILE is
- Microsoft NMAKE-compatible. To create a debug build, issue the NMAKE
- command in the Command Prompt window.
-
- Usage
- -----
-
- APTCLIEN is an application that you can execute directly from Windows in
- the normal manner or from the Command Prompt window. No command line
- parameters are recognized by APTCLIEN.
