Restricted Visual FoxPro Files

Visual FoxPro installs files on your computer that are restricted and may not be reproduced or distributed, including:

  • Some wizard files
  • TrueType fonts
  • Help files

Redist.txt

Visual FoxPro contains many files that are licensed for your use for design, development, and testing purposes only. See Redist.txt, located in your Visual FoxPro directory, for a list of redistributable files.

If your application contains files not in Redist.txt (other than files authored by you), remove them. Under the terms of the Microsoft License Agreement you received with this product, you aren't permitted to ship these files in your application or on your disks.

Distributable Files

You may distribute any Visual FoxPro file that isn't restricted. Pursuant to the Microsoft License Agreement you received with this product, files must be distributed in conjunction with a corresponding application. The following guidelines apply to distributable files.

Samples

Files in the \Samples\ folders and in the \Api\Samples folders are provided for you to learn from and build on. Although you may not distribute unmodified Visual FoxPro, you may refer to portions of sample application code as examples for building your own application.

If you use any files in these directories (including all .bmp, .ico, and .cur files), they must be included in your project and in the application build. They must not appear by name on the distributable disks and may not be distributed independently of your applications.

Class Libraries

You can use any .vcx file, including those in the \Ffc and \Gallery directories, the wizard class library, Wizstyle.vcx, and the sample class libraries without modification in your applications. The libraries must be included in your project and in your application build.

ODBC Files

Please refer to the Microsoft License Agreement you received with this product for specific restrictions with respect to your redistribution of ODBC files.

ActiveX Controls

Visual FoxPro includes a set of ActiveX controls (.ocx files) you can add to and distribute with your applications.
