I've been experimenting with the BackgroundWorker class. As a test, I've
built an application that searches for files matching a RegEx and populates
a listbox with the results.
My approach is to search directories recursviely andcall ReportProgress once
per directory or in batches of 10 matching files if there are a lot of
results. I pass an ArrayList containing the matching filenames. In the
ProgressChanged event handler I add the...

I'm using a BackgroundWorker to perform a file download from an ftp site.
Per good code design practices where I separate my UI code from my core
logic code (in this case my Download file method in my FileIO class) I've
established Public Event in my core logic classes along with RaiseEvents
(that will updated a progress bar on the UI side). This all works great
when I'm NOT using Threading (BackgroundWorker), however, as soon as I...

Hi,
My application has a BackgroundWorker component that runs a time-consuming
process. I use the ReportProgress() method to increment a ProgressBar.
However, in addition to that ProgressBar, I would also like to have a
multi-line text box in which I provide more details of the progress by
displaying message such as "FIle opened", "Reading contents", "Uploading
data" etc. Is there any method in the BackgroundWorker that can take the...

Hi all,
I am migrating a Windows Form application from .Net 1.1 to 2.0. I try to
use BackgroundWorker object to handle a very lengthy process.
I have a separated class to handle some very complex logic. In .Net 1.1,
I create some events inside this class to notify WinForm the status of
process:
obj.OneFileStarted += new OneFileStartedEventHandler(obj_OneFileStarted);
obj.OneFileFinished += new...

Hi,
I am having trouble seeing how this bolts together.
The UI starts a process which involves a long running database update.
All Database activity is handled by a class called DT.
DT has a progress event.
So I added a bw to the form. The Dowork Calls a method which instantiates a
DT and calls its Dataprocessing method.

Hello all,
I have an app that uses a BackgroundWorker() object to read USB data
that is being fed in serially (FT245R chip, www.ftdichip.com). It
looks just like a serial data stream. Anyhow, it reads in the bytes
and finds the header and footer and pulls packets out of the data
stream. Nice, easy stuff. It then stuffs the packet into into a
class I made up to pull the data out through the ProgressChanged
event. The class is pretty...

Hi,
I have a form with a progress bar on it and wanted to use the
BackgroundWorker to be able to update the progress. I looked at examples, run
some of them, but in debug, when the code gets to the do work method, it
stops for a long while and then executes the first line of the method and the
doesn't do anything else.
What am i doing wrong?

How do I implement the "incremental results" with a BackgroundWorker?
Many pages,
http://msdn2.microsoft.com/en-us/library/wewwczdw.aspx
for example, tell that I should subclass the ProgressChangedEventArgs
class, but what else? I haven't found any examples. (Why aren't there
any?) Right now I have derived my own version of
ProgressChangedEventArgs with some extra properties, declared

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
