How to create a progressBar?
-
-
Put a ProgressBar on the form and modify the Value property according to the progress that it is being made. You'll have to calculate that as a percentage yourself. (assuming that you show it like x %)
FYI you can set the maximum value so you don't need to calculate percentages. If you have 5 steps, set the Maximum to 5 and increment the value by 1.

If you have to do heavy calculation. A Better idea is to do it 'a part' in another thread. Use thread safe methods to update your progress bar

you can use
BackGroundWorkerFor that. becuase if you used progress bar for heavy operation your GUI will not respond becuase it give the priority to operation not GUI so your progress bar will not refresh. useBackGroundWorker Components in C#. that will help you.cheers, Abhijit

Moviereview ArchiveYou can calculate a percentage for textual output in addition to a progress bar (I think that's what blackjack meant) by dividing two doubles... of course you should know how to compute a percentage. Then you can use string functions to round that to a certain number of decimal points, but alas, I don't know the exact syntax.

I second that. Threads are always best for long-running background operations, just remember to perform control updates on the control thread, as lisan mentioned. Using threads will also allow you to have a "Cancel" button that can abort the background operation (if you periodically check for a canceled state in that thread, since actually aborting threads can be dangerous).

thanks for your reply, but I fail to see that it could be useful for me ;-)
