Pool Manager Sample (Custom OLE Automation Server) in VFP 5.0

• Microsoft Visual FoxPro for Windows, version 5.0

SUMMARY

This article describes the Pool Manager sample in Visual FoxPro 5.0. The Pool Manager is an example of a Custom OLE Automation Server created in Visual FoxPro.

MORE INFORMATION

The Pool Manager sample (located in Samples\Servers) illustrates Custom OLE Automation Servers, created in Visual FoxPro, used to balance work loads and handle job requests from clients.

NOTE: The sample is merely an example and not necessarily optimized for use in an industrial setting.

You (the client) can send jobs to the Pool Manager (Visual FoxPro Custom OLE Server), which might be remote, and have the Pool Manger handle the job processing. This allows you to continue working (asynchronously) because the Pool Manager is handling all the work. The client does not need a timer continuously checking to see if a job is done, because the Pool Manager makes an OLE call back. The jobs requested are dummy simulation jobs.

You can expand the Pool Manager class to provide better control on how many servers to deploy, timing of servers, and so forth. All of these are variables that can be controlled by the user to impact performance.
