Background Worker And A For Loop?
Apr 15, 2009I have an issue that I can't seem to find a straight answer for anywhere... I have a For loop that sends a file name to a background worker that contains some long running code and I can't find a way for the parent thread to wait for the background worker to finish... Here is the example code:
For 4
BacgroundWorker1.RunWorkerAsync(fileName(i))

Multithreading - .Net Asynchronous Background Worker Inside A Loop?
Jul 8, 2010Im using Vb.net visual studio 2008. i have got a process(system.diagnostics.process) to be run in background and it updates the Ui thread progressbar and a label and i have worked it using backgroundworker.runworkerAsync. Now the problem is i have to work the same process for a number of time with different inputs.
The code block is :
Private Sub fnStartEvent(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStart.click
Dim inputFolder = Directory.GetFiles(textboxSourceFolder.text)
Dim currentNumberOfFile As Integer=1
[code]....
The problem in here is the fnStartEvent method once gets started, it calls BackgroundWorker1.runWorkerAsync process and that runs in a seperate thread and does not wait for the thread to complete and it moves to the next line of code i.e loops to the next item and it returns to same BackgroundWorker1.runWorkerAsync line and throws exception that it is already running.
Tried
1.
Private Sub fnStartEvent(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStart.click
Dim inputFolder = Directory.GetFiles(textboxSourceFolder.text)
Dim currentNumberOfFile As Integer=1
[code]....
But this does not updates the Ui thread used to denote progress.
2.Put the whole process inside the DoWork thread and loop for each file in there itself, but that to returns the cross thread error in progress bar updation.what is the standard procedure in executing a loop for the backgroundworker to wait for finishing as well as update the UI without blocking it.
Write A Thread Into My App Which Basically Does A Loop In The Background Performing Detection?
Mar 15, 2012I've been able to write a thread into my app which basically does a loop in the background perfroming detection for a device being added or removed.works great!i am trying to implement another thread to check for a file on the found device...but i still haven't figured out threading enough to make this work, the versions i try to implemt are either looping along with the initial loop or cancelling itself because its already running.i've been trying to put a variable in that would switch the thread off, but it doesn't seem to work.

View 29 RepliesEvaluates Loop Condition In Do...Loop Statment To Determine Whether Loop Instructions Should Be Processed
Mar 14, 2011Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

VS 2008 With Background Overlapping?
Feb 5, 2010I have a vb app that I completed a few months ago and it has been working as it should.I have blurred out part of the image for business reasons. But you can see in the second picture in the top left it has the bottom right of the background overlapping in it.
I copied the exe file over to another computer and Im having an issue where the program will load and look OK but then after about 5 seconds part of the background will show up in the top left corner. Im not sure why. It is the exact same exe on the other computer but it only does it on this computer.I have attached images below so you can see what Im talking about.Im not sure if its a program issue or a setting on my computer.
Multithreading - .NET 2008 Background Worker?
Apr 14, 2011I have created a background worker using a tutorial. I understand some basic stuff like how to update a label or a progress bar from inside of it. The purpose of this background worker is setup a bunch of variables that are going to be used by several other background workers later. The variables i am setting up are 6 different lists and a multi-dimensional array. The code looks like this for the background worker at the moment.
Private Sub My_BgWorker_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles My_BgWorker.DoWork
For i As Integer = 0 To m_CountTo
[code]....
I would normally use the persons.add to add something to the list, but I'm having a really hard time wrapping my brain around an easy way inside of the backgroundworker to add new values to several different lists(which are going to vary in amount of data values). Is there an easy way to do this? I'm used to just having invokes at the top of a sub to do this but those don't seem to work inside of a dowork sub.

Jun 6, 2009the user of my application is able to run a diagnostic tool which is part of my application. This diagnostic tool searches every file on the computer, logs the names, and if the my program is able to then the file will be read.
My program has other uses as well. If the user wants to do something else in my program then i want the diagnostic code to run in the background. I don't want this code to prevent users from using other features of my application since the diagnostic search does take time.
How do i do this? Threading? A background worker? If the anwser is Threading which i am pretty sure it is, how do i set up a thread? My computer has 4 GB of RAM - 2GB & 2GB so i know i am able to do this smoothly.

Dec 23, 2010i am currently trying to improve my skills regarding simple graphics. currently i have a form with a background image. on top of that there is a movable image drawn during Form_Repaint. the image is a character that is animated. you click and the character moves to the new point. that all works great atm. i am even able to add new "AI Chars". they just randomly walk through the form and every time they stop, there is a 10% chance every 15s that they move somewhere else (random point). as is said, that works great. but now i am kinda stuck. since my "engine" (lets say so) is in isometric perspective, i need the ability to scroll.
