Thanks
I just modified your code so I can open a list of tables stored in table.
Thanks again
*-----------------------------------------------------------*
Local lnError, mytable
Store 0 To lnError, lnCounter
ON ERROR LNERROR = ERROR()
USE UPD_TABLES ORDER NAME
SCAN
mytable = ALLTRIM(UPD_TABLES.NAME)
myorder = ALLTRIM(UPD_TABLES.ORDER)
SELECT 0
IF EMPTY(myorder)
USE (MYTABLE) EXCLUSIVE
ELSE
USE (MYTABLE) ORDER (MYORDER) EXCLUSIVE
ENDIF
DO WHILE LNERROR <> 0
=MESSAGEBOX("Could not Open Table :- "+ UPPER(MYTABLE) + CHR(13) + ;
"ALL USERS SHOULD BE OUT OF THE SYSTEM NOW, " + CHR(13) + ;
"Press OK to Try to Open the Table Again....",0+16)
LNERROR = 0
IF EMPTY(myorder)
USE (MYTABLE) EXCLUSIVE
ELSE
USE (MYTABLE) ORDER (MYORDER) EXCLUSIVE
ENDIF
ENDDO
ENDSCAN
USE IN UPD_TABLES
ON ERROR

>>I need to open the tables exclusively in a form that contains alot of update operations on different tables, the problem is how to open all of my tables sucessifully if other users in the system, so I need to give the user a message and try to open the failed table again until I open all of my tables.
