 From another thread, I noticed that you are working with a database -- 
if you want to populate the combo box from a query result set, just 
write the query as "SELECT DISTINCT ... (whatever)...". Or if there is 
already a unique index on the column, then there will be no duplicates.

Things like this are much easier to enforce in the database back end.
