Is it possible to set the stack size for the thread created by
BackgroundWorker like in the API call _beginthread? If not is the stack size
a default or the one I set for the whole application?
(What I need is a worker thread with a rather large stack in a Windows Forms
app complied with /clr:pure)
Cheers

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,
I'm working on an app to filter images (by size, EXIF info etc..) and display as a slideshow. To allow the worker thread to continue running whilst performing the longer tasks such as loading the image and reading the EXIF data, I have put my code for finding the next image in a BackgroundWorker thread.
My problem is that this code accesses several ListViews and variables in the UI thread, and also needs to write to some labels and...

Does someone know why BackGroundWorker.ReportProgress method doesn't
accept strings ?
You can't pass integer always for a progress meter as percentage
completed cannot be calculated in many tasks like logging on to a
remote computer. In that case, we would like just to show a message
"Logging on"....
Any ideas ??

Is there a way to immediately terminate a BackgroundWorker thread? My
problem is that the BackgroundWorker starts with a call to
My.Computer.FileSystem.GetFiles that can run for a very long time if
it is pointing to a directory tree with many files. If the user
requests cancellation during this time, the main thread can call
CancelAsync and can post a "Cancellation Pending" message to the user,
but the BackgroundWorker cannot respond to...

Hi,
I am writing a small utility to perform system maintainence tasks on
Windows. In this, I am launching a MMC snapin as a process using
BackGroundWorker and using the "RunWorkerCompleted" event handler to
know when the snapin was closed. This works fine on Xp and Vista 32
bit and the RunWorkerCompleted event handler is called when the snapin
is closed. But on Vista 64, the RunWorkerCompleted event is called as
soon as the snapin is...

I have a question.
One day i have been working with threads. Thread had 'while' loop that
checked locked value telling the thread when application was closing
( in Dispose method i set locked object's value to 'true'). If i
didn't have the locked object the thread was present in taskmanager
even when application has been already gone.
My question is:

I want to create a "thread manager" class to manage an array of
backgroundworkers. I'd like this thread manager class to live in a class
library and I wasn't sure if it was possible to make the thread manager a
subclass of the backgroundworker so that I could start it up and still do
other things on the client. Essentially a thread that spins off new threads.
Am I going to hit any limitations here?
thank you

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:

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,...
