Accessing the Visual FoxPro API

If Visual FoxPro does not include the features you require for your application already, you can extend its capabilities by creating a Microsoft ActiveX control (.ocx file) or library (.fll file) specific to Visual FoxPro.

In This Section

  • Accessing APIs
    If your application has requirements that cannot be met by the features already built into Visual FoxPro, you can extend the program by taking advantage of external libraries — Microsoft ActiveX controls or dynamic-link libraries (DLLs).
  • Extending Visual FoxPro with External Libraries
    You can add 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.
