> >           Synchronize(UpdateDatabase);
> You might want to look at using Sessions instead.  They are designed for
> allowing multi-threaded access to databases.
>>>> Could you please give me a little sample? I don't understand about the
word "Sessions".

> >   FreeOnTerminate = true;
> You should set that in the constructor instead.
>>>> Firstly I have this statement on ONLY constructor but I need to make
sure, so I put it before thread terminates again. Anyway, I will put it out.
Thanks.

> >   Terminate();
> There is no need to call that since you are not using the Terminated
> property afterwards.  The thread will be terminated when Execute() exits.
>>>> Thanks again, I thought about it too but I have seen a little sample of
another that just use it to make sure.

> >   catch (...) {
> That generally is not good to use for catching VCL exceptions.  You should
> use this instead:
>     catch(const Exception &)
>>>> Thanks about it. It is a new idea for me.

> >   delete ADOQuery;
> Are you sure that your code reaches that line correctly?
>>>> Yes, because I have ever put the log (write file) to see the process
and that always pass the bottom of the Execute line in thread.
