hi larin,

Thanks for your answer...I experience before, that using an user interface in COM will result the same error.. but this time i have no user interface in COM that i create only EXCLUSIVE command...here's my command in COM :

SELECT 0
USE H:\Payroll\Data\Employee ORDER TAG id_no ALIAS Employee EXCLUSIVE

How is it happen? i think EXCLUSIVE is not user interface... do you have any idea or suggestion on how to control this problem...i really want to know about it...I'll wait your respond and appreciate it so much... thanks...
