About timer in MFC

Hello,

I am developing an application in VC++ 5.0/MFC. This application is to be run for 2000 hrs. continuously. I have to take readings periodically using this application. For that i am using StartTimer() and KillTimer(). I want to ask whether they work perfectly for this much long time and also if windows OS is run for 2000 hrs is it ok? Will it cause time lag after some time or not ? Thanks.

Timer handlers are not guaranteed to be called. Depending on the circumstance (e.g. Windows is busy doing something else), they may not be called. You will want to have the intervals fairly frequent because of this.

I haven't really researched it, but (other than first paragraph) I would think that it should be fairly reliable.

Timers are not precise, so you may wish to check out another method.

ok. i have to take readings minimum at 1 minute. so accuracy should not be much problem. What about windows OS? Any problem if it is run for a long time?

You're leaving yourself open for a lot of anti-MS comments here :-)

Windows OS should be fine for long periods. Win2000 especially as it has been written for use in servers (which are supposed to have very high availability). I don't thinkg you'll find the OS itself is really a problem.
