a New Service</title><prolog><metadata><keywords/></metadata></prolog><conbody>
<section><title>Introduction</title> <p>The server application framework exists
to support platform-level services between client and server applications.
These services have to be defined in order for clients and server applications
to communicate meaningfully. </p> <p>The general pattern for implementing
service support is shown in the following diagram. Client and server support
for the service can be implemented in DLLs. A single DLL, shared between client
and server support, allows the IPC protocol between client and server to be
hidden. A client of the service uses the services through service support
DLL interface and server application framework interface. A server application
derives service support DLL classes and server application framework classes
to implement the service and the server application interface. </p> <fig id="GUID-34FD3DA8-E488-5AE7-81C9-DB944B478056">
