Here's a related KB article:

Programmatically Accessing Windows Control Panel Options

It's a bit old though

>The VFP 6.0 documentation for the RUN command contains this example:
>*************************************************************
>The following example opens the Windows color picker from the Windows Control Panel:
>
>! /N CONTROL COLOR
>**************************************************************
>Actually it opens the Appearance tab of the Display Properties dialog. Does anybody know if there are any other dialogs that can be opened with the RUN command?
