This isn't specifically a VB problem, but I'm sure someone here can answer it.
I need to estimate the time remaining for a process. The variables which I want to calculate it with are the completion ratio (0 - 1), and the time that has elapsed since the process began.
From this I should be able to calculate how many more seconds remain, right? Well I don't know the maths of it, so can anyone help me out?
well the question is sufficiently vague :DQuote:

If you are looping i = 1 to 1000 you could calculate percent complete as i/1000 and use the system time to track seconds/minutes/etc
That what you mean?
I need it for a file encryptor. Let's say that the encryptor is 80% complete, then the ratio would be 0.8. If this was done in 16 seconds, then you can work out that the encryption will be complete in about 4 seconds.
I just can't seem to work out how the convert the above into an equation.
(Now - StartTime) / PercentCompleteQuote:

Thats the psuedo code anyway ... If you are using VB6 youd use DateDiff with Now and StartTime as arguments ...
A-ha, that calculates the total time the process will take. I can work from that, thanks
