i have problem with the reportprogress / progress changed.i use the backgroundworker in a form class named frame menu. the do work sub of the backgroundworker calls a sub X in a public module.
from the backgroundworker do work sub i am able to use the backgroundworker.reportprogress / backgroundworker progress change method and this is displayed on my form.
when i am using the backgroundworker.reportprogress / backgroundworker progress change method from the sub X it does not display on my form.
when i debug the code it calls the backgroundworker.reportprogress / backgroundworker progress change method correctly in the sub X but just does not display it on the form.
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
parser Private Sub BackgroundWorker1_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker1.DoWork Dim worker As System.ComponentModel.BackgroundWorker = DirectCast(sender, System.ComponentModel.BackgroundWorker)
I am using backgroundworker thread in my app. I also have a class in my project and am able to updated the user UI from the form, but most of my time consuming operation happens in the class so I tried to do an update like this Form1.BackgroundWorker1.ReportProgress(4, strname), but I get an error that say that the backgroundworker is not set to report progress.
I have this set in the load event for the app.Are you not able to call form items like this from a class?
I need to report progress changed. Consider the following code:
Public Class Calculator Public Event CalculationProgress (ByVal sender As Object, ByVal e As MyCalculationProgressEventArgs) Public Function Calculate(..).. ' Perform calculation here ...
[code]....
How and where should I subscribe to CalculationProgress event to call
I have a program that downloads information from another class, specifically it collects domain names.So i have a class called domainscraper....on my main form I have a background worker and progressbar, and i put this in the dowork event:DomainCollector.GetDomainsByMethod(parameter)Now my question is, how could I report progress to my progress bar on form1.vb from that method I use in the the domainscraper class (domainscraper.vb).
Is there currently any possible way to report progress of my unit test? I have a test that could take up to a hour, and I don't want to sit there not knowing what % it is done with. I have tried writing with debug.print and trace.writeline, neither of which seem to work.
I was wondering if there was a way to call defrag.exe from my vb.net program but also be able to watch the progress?I am not reinventing the wheel I am simply making a small app for my customers computers (for free) that will automatically perform disk cleanup and defrag to a schedule not requiring the end user to do absolutly anything (+some other tasks and features)
I have my disk cleanup all working but for the Defrag I would just like to use the windows defrag for instance (defrag C however I have a small GUI with progressbar and % indicator is there anyway I can get progress to report back. I know Windows defrag is compeltly different in Windows 7 I am not sure if this is even possible?
I 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.
how can i attach a progress bar to a crystal report progress control, my code extracts the data from the SQL Server database and displays it on a crystal report. all this process may take long time as the data size may be large or joins may take time, so how can i display this progress in a progress bar. How to attach hidden processes to the progressbar.
I wish to add a progress bar in code. I have a sample here but with the "Cursor.Current = Cursors.WaitCursor" to notify the user that it running.. however a progress bar maybe can make it more noticeble. how can i do that.
Private Sub CmdOK_Click(ByVal sender As System.Object,
I am using background worker to report progress on the screen. In the Main.vb I have the following
Public Sub report(ByVal sender As System.Object, ByVal e As System.ComponentModel.ProgressChangedEventArgs) Handles bwlistener.ProgressChanged Dim message As String = e.UserState logRTB.AppendText(message & vbCrLf) End Sub
When I call this from Main.vb I use: bwlistener.ReportProgress(0, "Some status text goes here") It works great. The problem is when I try to call it from any other module in my project.
When I call it OtherFile.vb: Main.bwlistener.ReportProgress(0, "Some status text goes here") It doesn't work... The program doesn't crash. Debug goes through everything but no output is actually shown to the end user.
how I can reference a report variable in the Report Properties Code Window of a local report? I have tried Variables!Claimant.Value (for a variable called Claimant) but I get an error "Reference to a non-shared member requires an object reference." I have tried qualifying it with Report. and also with the report name in front of it but I get errors with this also.I have the variable CLaimant defined in the Variables section of the Report Properties.
im making a web browser which is intertwind in a project, but i cant get the progress bar to display the current percent of a page that is loaded, i want to have 10 segments, each standing for 10% of the total page loaded. So say a page is loaded 67%, 6 out of 10 of the segments will be shown.
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.
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?
frmMain - Allows user to pick process or combination of processes they want to run frmProcess - Shows progress of their selection I have three modules. Each runs a specific process. The frmMain allows the user to run any one of the three modules individually or all together in a single process (basically, runs the one after the other until done).
I have a filesystemwatcher which place files in a queue when they are created. From the queue the files are further processed (xml into SQL database).
The mechanism works fine, but I want to add a progress bar to follow the progress of the files in the queue: processing 1 of 10......2 of 10......3 of 10 etc.For testing, I created a batch file to simulate the creation of files, so the filesystemwatcher can to his work and place the files in the queue. When I tell the batchfile to simulate the creation of 20 files, I see that the amount of files in the queue change. For example;
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:
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.
When i pass the parameter and run the report it works fine as i close the form it closes the form is there any way so that i should be able to close the crystal report viewer and pass the parameter again and should be able to view report again.
I got a problem I want to print a report which is receipt having size 3 x 4 cm. i am unable to resize crystal report. i am using crystal report coming with visual studio.net 2008.
I created a button instead of the print button in crystal report because i need to record the report printed report serial number, date and time to the database. when i click on the button, dialog box appear. if i click on the ok button , system record the printed report details to the database and report printed successfully. but when i click on the cancel button , system again recording the printed report record.
I have created an application using vb.net 2008 and for reports Crystal Reports Basic for Visual Studio 2008 but the problem is, when I run the application in another machine away from developing box, I get the Load report failed notice. I don't have any idea on how I should approach this issue. I tried installing the CRRedist2008_x86 and CRRedist2005_x86 but still the problem won't go away.
I'm having a problem with my crystal report with regards to report footer. I want to display the data from the table, column name "Remarks" in report footer but when I try to call the data it doesn't show the remarks. I'm using VB 6 and mdb files as my back end. Is there any command or fundamental that I've missed?
