Question:
Why can't I use the ixUnique option when creating indexes for
Paradox tables with the AddIndex method of the TTable component?
Answer:
The index options used in the AddIndex method of the TTable
component are table specific. For example, the ixUnique option
works with dBASE tables but not Paradox. The following table
shows how these options apply to dBASE and Paradox tables.
