I wanan update the content of a table in my program, before saving of course I have to check if any other is using the table, so i tried to use the example from MSDN about IsExclusive..
my program:
1: set exclusive off
2: open
in 0 exclusive
3: if IsExclusive() then
4: **do the updates here**
5: else
6: **prompt error message**
7: endif
To test the program, I open the database exclusively in another program, and then run the above code. A "access denied" message pops up at line 2.
So what should I do, if I wanna ensure there's no one using the table, and then update it?
Thanks for any help in advance!
