You can expose functionality that other applications can use by creating Automation servers in Visual FoxPro.
For example, you can create an Automation server that displays reusable forms or packages a complex routine into a more simple component that other programmers can use. You can create classes for creating objects to handle enterprise-wide business rules. A client application can use those business rule objects to call methods and pass parameters to the Automation server, which can retrieve or store data, perform operations, and return results.
