Hi,

I was wondering which would be the least resource intensive among the 3:

Timing m = 200, n = 100
1) 2 CWnd::SetTimer with 2 different IDs and 2 different timings

Timing m = 200, n = 100, where the greatest common divisor is one of them.
2) 1 CWnd::SetTimer with 1 ID and 1 timing where it is equal to 100 and the CWnd::OnTimer method has a counter which will call the relevant methods.

Timing m = 300, n = 200, where the greatest common divisor is not one of them.
3) 1 CWnd::SetTimer with 1 ID and 1 timing where it is equal to 100 and the CWnd::OnTimer method has a counter which will call the relevant methods.

If you can rank them, it would be even better. Thanks!

Timers are a scarce resource: always use the absolute minimum you can get away with! So, go for 2 or 3 - but I don't see much difference between them from your description.

So if I were to say that my program have about 20 of these timers, I should try to group them together?

Limits are mainly thing of the past (Windows 3.x and in some case Windows 9x/Me). Thus, you don't have to worry too much about that if you are reasonable.
