Displaying an estimate of a procedures run-time

[fenris]

I have a program that has to calculate a large number of permutions (12! to be exact) and I would like to be able to display an estimate of long till the program is finished it's calculations (something similar to what IE displays when downloading a file).


I was thinking of using the gettickcount api and having the program go through several iterations of the calculations and then determine a runtime from that, periodically updating the estimate.

Is there a better way? Troy Williams B.Eng.

The appraoch you outline is probably O.K., but may not be much more accurate than just getting a 'ball-park' figure from a few (timed) manual executions and 'asssuming' the average for all. If you use this, just Multiply the 12! times the avg and use it as the total, decrmenting the 'time-to-go' with each iteration.

I am sure that you are aware that ~500K iterations of 'something' needs to be quite a simple calculation to get finished in a reasonable time.
