Rena,

There are 3 major timers in Net when you do not call the
environment.tickcount a timer.

system.windows.forms.timer
system.timers.timer
threading.thread.timer

If you can avoid the last one by using the second I would do that.
While in a simple situation I advise the first.

Have a look for those.

I hope this helps?

Please describe in more detail what you want to do. You don't need a
timer in .NET to create a new thread.

Hi Rena,

Now I readed the message from Herfried I maybe understand your problem
better.
You don't need a thread in .NET to create a timer.

See my previous message for that.

Rena,
In addition to the others comments, the following recent articles in MSDN
Magazine explain the difference between the three timer objects in .NET &
when to use each.

http://msdn.microsoft.com/msdnmag/issues/04/02/TimersinNET/default.aspx

http://msdn.microsoft.com/msdnmag/issues/04/03/default.aspx

The above articles also discusses if & how each timer interacts with
threading.

Hope this helps
Jay

I used the forms.timer to ack as a listener, I will try to retrieve data
from a Access database (real-time demanding),
and there is another client program to update the data when pressing
update(a form button).
However i found that the response time is very slow.

I wonder how it could improved, use threading? use other database? use
faster time interval?
Do any one have ideas about it?

Thanks.
