How to terminate a blocked thread?
In my form's "load" I launch a TCP listening thread that stays in an
infinite loop waiting for incoming TCP packets. In this form's "closing" I
try to terminate this thread by calling the "Abort" funcion. But the thread
does not terminate and after the form is closed this thread keeps running at
blocked state. Basically the application keeps running because this thread
does not terminate while...

After running into a design wall with my traditional thread approach, I
realized that a BackgroundWorker object would fit my needs pretty good.
Never really used them before.
In a nutshell, my problem is cancelling the worker. I've read the MSDN
docs, checked google and haven't found a solution.
The problem is, once I make a call to cancellAsync() (I check for
CancellationPending in my DoWork handler) and WorkerComplete fires, 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...

Does anyone knmow why an asynchronous worker method would crash if the
e.Cancel method is set to true, but not otherwise?
I'm working on a demo app with an asynchronous call, using the .NET 2.0
BackgroundWorker component. The app works fine if I let the worker method
proceed to completion. But if I cancel the worker method, it crashes.
Specifically, if I set the DoWorkEventArgs.Cancel property to true, the
worker thread crashes at the...

What happens here?
The backgroundworker (bgw) unzips RTF-Helpfiles (up to 1 MB in size).
The ProgressChanged-Event gets the unzipped files (to display them in a
RichtTextBox)
It follows the Trace that prints always what bgw has unzipped and what
ProgressChanged received:
1. bgw: HelpFilelistgzip
2. ProgressChanged: HelpFilelistgzip OK!

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

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

I start a BackGroundWorker to populate a grid. It is started off in
the ui layer
The thread follows( cannot think of a better word) the path
UI->Layer1->Layer2->Communication Layer
and it blocks (the server is executing somthing where which takes
time)

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

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,...
