• Accessing the Visual FoxPro API
  If an external library is not available to suit your needs, you can write your own Microsoft ActiveX control or Visual FoxPro -specific dynamic-link library (.fll file). By calling the functions available in the API available in Visual FoxPro, you can create controls or libraries that are tightly integrated with and optimized for use in Visual FoxPro
• Extending Visual FoxPro with External Libraries
  You can add Microsoft ActiveX controls (.ocx files) to your application easily, which provides you with new objects to use in forms, to subclass, and to manage the way you work with native Visual FoxPro controls. In addition, you can link to an external library, such as a DLL, and call the library's functions to use in your own programs.
