UI Not Responding During Nested For Loops
Posted on 2006-11-25
I have an outer For loop that runs 1000 times, and an inner For loop that will run about 3000 times, about 3 million times in all. About 10% of the way through it, the UI stops responding. The calculations keep running and eventually it's responsive again, but the problem is the progress bar locks up and a user would have no real way of knowing if the program is frozen or just too busy to update itself.
I tried making the progress bar separate from the main UI (a separate window pops up with a new progress bar) but that locks up too. It's only called 1000 times from the outer loop...so I don't know why it locks up.
I guess there is just something wrong with the design here. Can anyone offer advice on how to effectively use a progress bar in such a long calculation?
Thanks in advance!
