Server Samples

  • Статья

Visual FoxPro includes several samples, which focus on Automation Servers. An Automation server is a COM component application that exposes functionality that can be used and reused by other applications through Automation. In addition, you can create one or more classes to handle enterprise-wide business rules. A client application that uses the business rule object would pass input parameters in a method call, and the Automation server might then do a great deal of work, retrieving or storing data from various sources and performing complex calculations, before returning the answer.

  • FoxISAPI Automation Server Samples
    Visual FoxPro includes an ISAPI extension called Foxisapi.dll that creates an instance of a Visual FoxPro automation server and then calls a method on that server that returns HTML. The FoxISAPI extension makes it possible for you to access Visual FoxPro custom Automation servers from any ISAPI supported Web server, such as Microsoft Internet Information Server and Microsoft Personal Web Server.
  • Gopher Automation Server Sample
    This example simulates a smart search business object, which locates a customer that might be contained in one of many different databases. This makes it possible for you to use Visual FoxPro in a three-tiered model where user services are not tightly bound to data services, as is the case in many of today's client-server environments.
  • Pool Manager: An Automation Server Sample
    In this example, job processing can be handled by a remote computer. This makes it possible for you to continue working, because other resources handle all the work.
  • COM+ Samples
    Samples for using Queued Components, COM+ Events, and Compensation Resource Managers are located in the ..\Samples\COM+ folder. For more information, see the Readme.htm file in the folder.
