VS 2010 Backgroundworker And Kleinmas's Download With Progressbar?
Oct 14, 2009I have a class that downloads a specific file from the net.This class uses a BackgroundWorker. I tried to implement kleinma's Download Files From Web With Progressbar [URL]../showthread.php?t=396260), but I'm having difficulties making it work. I'm including a test project, so if someone is willing to take a look at it, it would be great .
The part I'm having trouble with is updating the progressbar and progress label. The errormessage I receive is in Norwegian, but it has something to do with threads. I suppose I should use Invoke or something, but I don't know where to start..
Marquee ProgressBar With BackGroundWorker/
Nov 26, 2009I've got a form that has a ProgressBar on it. The Style is set to Marquee. In the Form.Shown event handler, I call BackgroundWorker. RunWorkerAsync(). In the old version, while this is occurring in the background, the ProgressBar is scrolling, which is exactly what I want.I copied over not only the code from within the file (i.e., the logic code) but also the code from the designer file. So, from what I can tell, there should be NOTHING different between the two files. However, in the new version, the marquee scroll doesn't occur.

Feb 22, 2011I am trying to use the background worker to keep my application responsive during the calculations it does. All I need is one to calculate and the other to count time which I use a timer for. But when I try to use a progress bar as well as I want to see the progress it gives me an InvalidOperationException: Cross-thread operation not valid: Control 'ProgressBar1' accessed from a thread other than the thread it was created on. I need this to work, how could I use a component from outside the background worker? This is the background worker bit:

View 4 RepliesBackgroundWorker To Update Progressbar And Label While Downloading Large File
Mar 10, 2012I place some code below to simplify the process.
1) I am trying to use background worker to download a large file and update a progress bar to reflect the changes as the large 5GB file is being downloaded, and also update percentage completed to the label.text(lblInfo).
2) As I was goggling I came across some info that a web client is needed to calculate the maximum size of the file and divide by 100 and you can stream it down with the web client. Reading it is one thing, implementing it is another as I spent week trying to get it to work.

VS 2010 - ProgressBar Added And Set To Continuous Style
Jun 20, 2012I have an application that has a ProgressBar added to it set to Continuous style. Everything seems to work great except that the progress bars seems to "fill in" slower than needed. As a test, I created a form with a continuous progressbar and a button. The button code only sets the progressbar's value to 100 (which is the max). Basically, for the test, the value changes from 0 to 100, but the ProgressBar seems to incrementally fill in like it is doing a PerformStep or something. I don't get it. Is there a way to get the ProgessBar to go from empty to immediately full when setting the value from 0 to 100 without the animated filling?

View 5 RepliesVS 2010 Wait On Repaint Before Exit - Progressbar?
Jan 6, 2012I'm having issues with a progressbar. I've created a progressbar that reads registry variables and uses that input to update the progressbar and some status messages (so I can call it from vbscripts, etc). I want it so when my status bar hits 100%, the bar stops, waits a few seconds, and then quits. However, it seems the program processes the remaining code and quits the application before it has time to completely repaint the progress bar (I'm guessing this because it will usually update to about 10% before it exits).. I'm using something like this...
If prcnt = 100 Then
progbar.Style = ProgressBarStyle.Blocks
progbar.Value = 0

I'm running it under a BGW and it works fine but is there anyone who can comment on it and make my code a bit better. I've a background worker and I am running it again and again on the RunWorkerCompleted like this
VB

Is it bad coding or is there any alternative to run it?
VS 2010 : BackgroundWorker Does Not Report Progress
Sep 5, 2010I have some issues with background worker progress reporting functionality. I'm implementing a progress indicator and even if I marked the backgroundworker as report progress (true), it won't report progress until it finish the job.
The code is like this:
Private Sub BackgroundWorker1_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork
action_1()
[code]....
The result is as expected (label1 with 100 value) but only when worker finished all the steps. If I'm triggering a messagebox in ProgressChange I see two message windows at the end of DoWork handle.
VS 2010 : Backgroundworker To Populate Gridview?
Feb 16, 2010I'd like to have a backgroundworker process data that will eventually populate a gridview in my windows form. I need to use a backgroundworker because the process takes a little while, normally causing the program to slow/freeze until it's opening and streaming connections.. So, I'm using a background worker to perform these methods.How can I take the data from the background worker (on a separate thread than the UI) and use it to populate controls in the UI?
View 4 RepliesVS 2010 Backgroundworker Error Only On A Condition?
Feb 16, 2010I cannot figure this one out.. I have a background worker that will perform a task streaming data from some webpages. this data is then passed back and displayed in a gridview. It has been working fine.
I've recently implemented a listbox, which its values will be passed into the function that the background worker will perform as parameters, originally i had taken a single value from a textbox.
Now, I thought maybe it had something to do with the listbox, so I used a static value, just a simple String, as the parameter, and again, I get the TargetInvocationException was unhandled.. There's no difference in how I perform the task I'm trying to have the backgroundworker complete, the only difference is where it exists in my if condition statement:
Private Sub BackgroundWorker1_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles ScrapeSites.DoWork
Dim results As ArrayList
Dim worker As System.ComponentModel.BackgroundWorker = DirectCast(sender, System.ComponentModel.BackgroundWorker)
