Hi guys

I have a routine in a multithread DLL.

Sometimes I have some trouble with the code running twice for some users.

Example:

procedure X;
begin
       if Table.FindKey([key]) then begin
           Table.Edit;
           Table.FieldByName('X').AsInteger :=
Table.FieldByName('X').AsInteger + 1;
           Table.Post;
       end;
end;

If the initial value is 1 the correct value after the routine should be 2. I
have a log to this operation with something like below:

OldValue    NewValue
1                2
2                3
3                4

Sometimes I only run the procedure once and it will produce two rows in the
log table (like two threads runing for the same clients).

I wonder if someone could drives me to prevent this type of thing. It could
be a problem with threads ?

Eduardo,

The only way that I can think of this occurring is if you have threads
stepping on each other's objects because they are not properly isolated via
critical sections or separate objects.

BTW, have you ever sent me the source code to this project ?  This could be
related to your issue with index corruption.

Okay, I'll take a look.
