- File: APTSERVE.CPP
-
- Summary: Based largely on the LOCSERVE.EXE source code, this module
- implements the main framework for a Win32 .EXE application.
- This application is meant to run hidden as a local multiple
- Apartment COM server that offers the Car, UtilityCar, and
- CruiseCar components. Though this local server offers a
- simple main window and menu system these are not seen during
- normal operation. This server can be run stand-alone for
- debugging purposes by explicitly using the -embedding command
- line switch and invoking APTSERVE prior to the client.
-
- This local server supports self-registration and this program
- recognizes the -RegServer and -UnregServer command line
- switches and has the appropriate functions (RegisterServer
- and UnregisterServer) to register this local server in the
- system Registry.
-
- For a comprehensive tutorial code tour of APTSERVE's
- contents and offerings see the tutorial APTSERVE.HTM file.
- For more specific technical details on the internal workings
- see the comments dispersed throughout the APTSERVE source code.
- For more details on the APTCLIEN.EXE that APTSERVE works with
- see the APTCLIEN.HTM file in the main tutorial directory.
-
- Classes: CMainWindow
-
- Functions: InitApplication, WinMain
-
- Origin: 3-20-96: atrent - Editor-inheritance from the LOCSERVE source.

- We include OLE2.H because we will make calls to the COM/OLE libraries.
- We include INITGUID.H only once (here) in the entire app because we

- We include APPUTIL.H because we will be building this application using

- We include MICARS.H and CARGUIDS.H for the common car-related Interface
- class, GUID, and CLSID specifications.
- We include APTSERVE.H because it has class and resource definitions
- specific to this APTSERVE application.
- We include SERVER.H because it has internal class declarations for
- the server's control object.
- We include FACTORY.H because it has the necessary internal class factory
- declarations for this component server.

- Function: WinMain
-
- Summary: The Windows main entry point function for this application.
- Initializes the application, the COM Libraries, and starts
- the main application message loop.
-
- Args: HINSTANCE hInstance,
- Instance handle; a new one for each invocation of this app.
- HINSTANCE hPrevInstance,
- Instance handle of the previous instance. NULL in Win32.
- LPSTR lpCmdLine,
- Windows passes a pointer to the application's
- invocation command line.
- int nCmdShow)
- Bits telling the show state of the application.
-
- Returns: int
- msg.wParam (upon exit of message loop).
- FALSE if this instance couldn't initialize and run.
