Background Worker Not Working Right?
Apr 27, 2010I have created a background worker to go and run a pretty long task that includes creating more threads which will read from a file of urls and crawl each. I tried following it through debugging and found that the background process ends prematurely for no apparent reason.
While Not myreader.EndOfData
Try
currentRow = myreader.ReadFields()
Dim currentField As String
[code]....
This first bit of code is the loop to input from file and this is what the background worker does. The next bit of code is where the background worker creates threads to work all the 'landingPages'. After about 10 threads are created the background worker exits this sub and skips the file input loop and exits the program.
Try
For Each landingPage As String In landingPages
pgbar.Timer1.Stop()
If VisitedPages.Contains(landingPage) Then
[code]....
Also my main thread runs a forms from where this background is called to run but the main thread is supposed to wait for the background process to end unless the user selects another option from the main form.
Background Worker , Working With Listview?
Dec 1, 2011ive developed my app and am im trying to improve its use ability. Ive created a dvd management app for myself and i have a function that retrieves all the data for all the movies displayed in my listview. It works fine but the interface hangs for the entire time.Ive decided to use a background worker so i can browse other movies with all the data is being fetched.Im having silly problems with getting the index value for my listview when im using the .DoWork()

the function works a dream whenvnot being called inside the doWork()

View 18 RepliesBackground Worker Create Second Thread For Progress Bar?
Apr 6, 2011I have searched the forum and found several forums related to the backgroundworker thread but have been unsuccessful in finding my answer.My objective is to display an animated gif or progress bar while the program is executing a particular method which can take upwards of several minutes to complete. I cannot get the second thread to run the progress bar while the main progrem is executing the time consuming method. I have created a demo based on another thread and can't seem to get it to create two threads. I was attempting to get the backgroundworker to execute the progress bar while my main code runs on UI thread.

Backgroundworker - Dynamically Create A Background Worker?
Jun 16, 2011I have a VB.net project which uses a background worker to do some stuff.
Now I want to expand the project to be able to do multiple stuff :)
A user can enter an URL in a textbox and when the user click on the parse button the program creates a new tabcontrol a outputs some data.
I use a hardcoded background worker for this.
But now I want to run multiple background workers to do this stuff so I can't rely on hard coding the background worker(s).
Is it possible to create background workers dynamically.
how to set this up since I think I need to set up the different methods and variables like:
Private bw As BackgroundWorker = New BackgroundWorker
bw.WorkerReportsProgress = True
bw.WorkerSupportsCancellation = True
[Code]....
I think I need to declare the background workers in some sort of array like variable (list / dictionary)??? Other then that I have no idea how to tackle this.

View 3 RepliesVS 2010 Run Another Program In The Background?
Sep 30, 2011is it possible to call another program in the background? I'n doing a project that uses .net to control a camera. the camera is nikon, which has a sdk. unfortunately, the sdk is an unmanaged dll, from the research I did, people complained that it is difficult to use it in .net. actually, no1 has example. but the sdk has sample in vc++. so, I'm thinking maybe can build the control program by vc++, then use vb.net or c# to it and run it in the background. so, I do not have to mess the dll to .net.
is this a good choice? or, not really? how to do it? if I use a console program, how to avoid popping up the cmd window?
Background Program To Detect When Regedit Tries To Run?
Sep 3, 2011I have Windows XP Pro, SP3 on a Dell Dimension 9150 with VB 3.0 and all other Visual Studios up to and including VS2010 Pro.I'm not exactly an expert VB programmer, but I have written several different programs.I would like to write a VB program to run in the background and detect when the program regedit.exe/regedt32.exe tries to run.Once the regedit program tries to run, I would like my background program to pop up a message with three options. Allow, Do Not Allow and Cancel.
The Allow button would allow regedit to run.The Don't Allow button will not allow regedit to run and continue to run in the background. The Cancel button would not allow regedit to run and would cancel the background program.Can this be done?I would explain why I want to do this, but it would take too much of this thread. However, if anybody really needs to know, I will accommodate their request.

View 7 RepliesSet Splashscreen Background Image In Program At Run Time?
Mar 8, 2011I have a splash screen for my program that I want to have a background image that changes each time the program opens.One way I saw to do this is to load it from a ImageList, but that has an maximum image size of 256x256.The splash screen is 498 x 305, which means that I need to find something besides ImageList but hopefully with a similar ability to organize the images.I did try just putting them into resources, but wasn't able to get it to set the background without erroring, and I'd prefer not to have 30 images cluttering the place up.
View 1 RepliesShell Program - Cancelling Background Worker
Nov 15, 2010I have the following problem. I have a worker in VB .net (2010) which runs a shell-program. The shell program is a service and output stuff like:
Server initializing...
Server opening port...
more info...
I am able to 'catch' the output of the shell and add it to a textbox (using set text function). And I am able to Cancel the worker by clicking on a stopbutton, however when there is no more output by the shell I cannot stop the worker anymore. At least I suspect that's the case. I've tried checking for endofstream (commented section) but that doesn't work. I've also tried to same code with some test text in stead of 'clsProcess.StandardOutput.ReadLine' and that also works. So I came to the conclusion it must have something to do with clsProcess.StandardOutput.ReadLine being at the end?
Try
clsProcess.StartInfo.UseShellExecute = False
clsProcess.StartInfo.RedirectStandardOutput = True
clsProcess.StartInfo.RedirectStandardError = True
clsProcess.StartInfo.FileName = serverpath + config_executable
