My option very simple:
In the load of the form create array (adir) with all of tables in current directory (On that point, there is not any cursor).
In the first line of the command button add array (aused), and do the following steps (My problem is to type the command acc vfp array commands, but you can see the prinsple):
1. select * from aused where the table\cursor not in (select table/cursor from adir)into cursor mycursors.
2. select mycursors
scan
ccursor=mycursors.field
use in ccursor
endscan
(Ohh, here I have to use once with 'use in mycursors')
Thank you if you can help me to build it.
