So this looks like your tarnsaction cannot connect to the database burt you're getting no error message but a hang. You could - check that anything inbetween your program and the database is actually working. Using another client program may help to narrow down the target - turn on logging for mysql temporarily (the log fills up fast) and check if mysql sees the connection attempt - instead of stepping over the first erroneous line step into and look what happens in detail HTH, Marc -- Marc Santhoff <m.santh...@web.de> -- _______________________________________________ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
