What do you mean?, This "error" is great to ensure your data is valid, not only saved!.
The update Conflict is some kind of warning to say your user is trying to modify a value entered by another user.
User A: Get MiTable.Field[1]="A"
User B: Get MiTable.Field[1]="A"
User A: Modify MiTable.Field[1]="B"
User A: Save the Data
User B: Modify MiTable.Field[1]="C"
User B: Try to Save/Update the Data... OOpppsss Update Conflict! Great!
Why this is great??, because the internal engine of VFP is detecting UserB has a "A" as OldValue, when it try to update, it seems your old values is not "A" anymore, now is "C" ¿?!!, Wooowww, somebody else change the data while UserB was editing. Is the way to ensure integrity on the data.
>Can somebody tell me, How is the best way to manage this situation. I want be sure that all the changes made it for all user will be saved. Thanks.
