Progress Bar - Show The Current Progress Of The Automated Tasks?

Mar 6, 2009

I have two forms, when the user selects a button, the second form opens and an external executable begins an automated process. The point of the second form, is to only show the current progress of the automated tasks and closes when those tasks are completed.How would I use a progress bar to show the current progress of an action on a different form without knowing how long it will take?

Progress Bar To Show The Progress Of The Current Task?

Jun 11, 2010

In the app I'm currently making, I have two progress bars. One for current task being committed and the other is for overall progress.During runtime, I calculate how many tasks are being run and set that as the maximum. As each task completes, the progress bar is incremented by one.

I want the current task progress bar to show the progress of the current task. Some tasks can take a few minutes to complete so that progress bar works great. But, if the task is super quick, like editing registry keys, I see no progress at all.When I edit the registry, it basically goes like this:

'Edit Key
'x
'x
'x
ProgressBar1.PerformStep()[code].....

It completes so quickly that I never see the bar even move.I also have each task report its name into a label and it skips ahead so quickly that I only see the first task name and the last.Is there any way to make this do a better job at reporting the progress?

I came across a problem in my program it takes too long to calculate the values needed (about 10 sec) .But thats not the problem you don't know when the program is working or not, as it just locks up until its finshed and I view that as a problem.

I need to be able to show the progress of this .I looked at using background Workers but I get exception "Object reference not set to an instance" I believe this is because the background worker cannot write values or something ,As it works will a normal handler.

Show A Progress Form?

Mar 1, 2009

I'm trying to do a form while a background process is running. Similar to a progress bar but not a progress bar. We have a form that has an animated gif (customer request) and that's it. no other controls. They want this form to show while the processing in the background is running. I try to do this but when the progress form is shown the animated picture is not shown and a white blank space is shown instead of the animated pic. How can I do this? It looks like the BW would work, but i'm not understanding how.

How To Show Actual Progress Of Data Transfer

Nov 21, 2009

When I move or copy files, I'd like to know how to show the actual progress of the data transfer.Something that I don't understand is how when moving or copying files to detect the actual progress of the data transfer. I always put the moving/copying in a background worker and that does fine, but presently I can only report status based on how many (of the total) files have been moved or copied.I've tried to look at the destination and my thinking was to report the progress based on the bytes there, but that doesn't work because it always sees it as being the complete file's size, even though that makes no sense.In fact, if you copy a file using Windows Explorer, it does the same thing, although obviously it's still transferring.

VS 2008 DownloadDataAysnc Doesn't Show Progress?

Feb 11, 2011

I am using the DownloadDataAysnc. But the ProgressChanged event doesn't show progress until after the data has been downloaded.Even when I try and download a data which is contained in a big file. The programs remains responsive so I know it is doing something.However, it is when the progress has completed that the progressChanged event fires.I known this as the progressChanged and the DownloadDataCompleted fire immediately after each other. However, they should be a pause as the file is quite big.This is the code snippet I am currently using. And the output below

Results:
Progress changed Version userstate: [ Version1 ]
progressBar1.Value [ 100 ]
