How To Add Progress Bar In .net (2005/2008) To Show The Application Is Busy
Nov 9, 2009
I working on a project wherein i need to merge 2 or more files. but while the program is running or doing the specified descripted job. it seems to be standing still, which may confuse the user that application is not working or not responding. so i want to add a progress bar or anything related to show that the application is still running. can someone explain or tell me how to add this in my program. can you explain me with a simple program or something.

Look at the first section of code below:
Private Sub vIV_Comp_Cert_Enter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles vIV_Comp_Cert.Enter
CurrForm = sender
[CODE]...
This code is used to load a PDF in a PDF viewer. Because the PDFs are sometimes huge and there is no idea on how fast the machines are that will access the app, I have created a form to show that the program is busy thus the "ShareClass.LoadingIndicator" routine.
Here is the ShareClass.LoadingIndicator Routine:
Shared Sub LoadingIndicator()
Dim frm As New LoadingIndicator
frm.TransparencyKey = Color.Magenta
[CODE]...
The problem I have is that when the app runs and these subs fire, the LoadingIndicator form shows up but the ProgressBar1 and Label1 show as all black on the screen. I tried to make a screen shot of this but the screen shot showed nothing as if the form wasn't even there. How can I resolve this? What I would like to do is make the LoadingIndicator form be borderless so it appears as a label and progressbar laid ontop of the loading PDF reader as the PDF loads. If I take the transparency off it works fine.

Im trying to show animated gif during busy process or loading. but it isn;t working rite. the gif stops to animate when loading instead and animates only when no loading is n progress. what i have done is to show formB from the formA. i load the gif into the picbox in formA and crete a new thread which will be opening another formB.
dim loadThread As Threading.Thread
LoadingGif()
loadThread = New Threading.Thread(AddressOf loadingForm)
loadThread.Start(formB)
but the gif doesn;t move at all unless another form is displayed.

I have a client program I wrote that waits for TCP communications. I found that when it was waiting, the form became unusable. I did some reading and learned about threading. Now it works great. Now I came to the point where I need to stop the program.. this is basically what I have:
[code]...
I figured I'd use the quit option to set the bool to false that the thread will see then do the proper closeout. However, it doesn't seem to work. After banging my head against the code, hehe, I realized that the thread is hung waiting for a client on the "AcceptTcpClient()" line.. so it's never getting a chance to evaluate SystemRunning.Is that an accurate assumption of the problem? If so, how does one deal with it?Also, I surmised that I probably should put my "end" statement at the end of the thread to be closed rather than my quit sub. I was afraid the marker boolean for the thread would get set and then the quit sub would immediately trigger "end" before the thread had a chance to close out. Is that also correct, or doesn't it matter?

I copied the code here and translate the code to vb [URL]it is working fine but there is one small problem but I cannot solve? Here is my code: SyncClientVB Another Source The scenario is... the progress is reported by an event (OnCopyingFile event)
Public Sub OnCopyingFile(ByVal sender As Object, ByVal e As CopyingFileEventArgs)
If pbFileTransfer.Value <> e.PercentCopied Then
If txtCurrentFile.Text <> e.FilePath Then
txtCurrentFile.Text = e.FilePath
[code]....
The problem is that it is ok when runned but when I click the form it starts to hang but in the console... it is still continuing.
dp.SyntaxHighlighter.ClipboardSwf = '/dp.SyntaxHighlighter/Scripts/clipboard.swf'
dp.SyntaxHighlighter.HighlightAll('6f5d1b01659646618ff3bdca29fb1b7f')

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?

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 ]
[code].....

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.

I am trying to implement a BGW and want to report progress to a progress bar for my TextFieldParser program, sometimes if your opening very large files it takes a while and I would like the user to be able to see the progress and have some interaction so they know the program is still running I am a little hung up on what to in the reportprogress
I have:
worker.ReportProgress(0, myReader.ReadFields())
and its not doing anything, I didnt expect it too since ReadFields is an array

I want my program to copy a file or two from a folder in the directory of the program to a given directory. I also want a Progress Bar for this. I am not too great at this stuff, so I am not even completly sure where to start at to do this. Edit: Not sure if this is possible with VB, but is it possible to just Download it to a given directory instead and show a progress Bar?

I need help getting a progress bar to show percent in it. I want to have the percent in the middle of the progress bar, like is sometimes seen in a few programs. I have googled this, and can't find anything. I found something on The CodeProject, but it was just a label and drawing a rectangle behind it. I would like the actual progress bar that is available through the toolbox.

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.

I have wrote a program that do a bit of calculations that takes about 10 min to complete, therefore I need to show a progress to user. I used a percentage in status bar to show the current status of program.
The problem is for updating the number after each iteration I use me.refresh to show the percentage. BUT whenever the program lose the focus for example working on other stuffs, the program cannot update the percentage anymore. And above the form shows not responding but do the job until get the result.
