Hi, i'm doing the following operation: I'm reading multiple rows from a database then writing each row into a dbf file using dbase_add_record. I'm having the following problem : - some rows are beeing written other or not to the dbf file (sometimes). - if i repeat the operation all the rows are beeing written to the dbf file Why is the same operation sometimes working some other times not working !!!!!!! ????? Thx in advance for any suggestions. __________________________________ Do you Yahoo!? Protect your identity with Yahoo! Mail AddressGuard http://antispam.yahoo.com/whatsnewfree
