Rick,
Thanks for the reply. The firing interval indicated in my original message might have been a little high (and will be user defined i.e. the user can change it) but it probably will not be less than one second.
Have you ever created a windows service that is using a timer in this way before? Any comments would be appreciated.
Thanks again for your reply and explanation.
Sincerely,
Einar

If I remember right these timers are pretty close to underlying OS APIs so there's very little overhead for them, especially in low firing intervals as yours (many seconds).
