hello
I have implemented a solution using async methods. There is one async
method that can be invoked multiple times, ie there are multiple async
"threads" running at a time.
When these threads are complete, the call the Callback method. Each "thread"
calls the same callback method.
What thread does this callback method exist on? My testing indicates the

I am working on a project where I will have a ton of async DNS calls in a
console application. I would like to process the results of the Aync calls
on the same thread that made the async call. Now I was looking at the Async
WaitHandle options. They are "WaitOne", "WaitAny", and "WaitAll".
I would like to process all of the results that are returned. However, due
to network performance and other factors not all of the results are...

Hello -
I am trying to write a class that has an async BeginX and EndX, plus the
regular X syncronous method. Delegates seemed like the way to go,
however, I still am having problems getting exactly what I want. Here are
my goals
1. I would like the IAsyncResult that is returned by the Begin function to
be able to be waited on or polled to check for completion.
2. The Begin function would take a callback, and the async process would

Im in a web page and call an asynchronous method in business class. the call
back method is in the web page.
When page processes, it runs thru code begins invoking the method then the
page unloads. When the callback method is raised, only the method in the web
page is run and the page never refreshes, it seems it all happens on the
server side.
I am trying to refresh the constrols on the page inside the callback method,
but when id...

Hi,
I've omitted a large chunk of the code for clarity but the loop below is how
I'm calling a delegate function asynchronously. After I start the each call
I'm incrementing a counter and then making the main thread sleep until the
counter gets back to zero. The call back function for each call decrements
the counter. Is there a better way to make the thread wait until all calls
are complete besides using the counter? I've seen some things...

Hi all,
Three questions really:
1) The async call to the networkstream's endread() (or even endxxx() in
general) blocks. Async calls are made on the threadpool - aren't we advised
not to cause these to block?
2) You can connect together a binaryreader to a networkstream:

It appears that System.Random would provide an acceptable means through
which to generate a unique value used to identify multiple/concurrent
asynchronous tasks.
The usage of the value under consideration here is that it is supplied to
the AsyncOperationManager.CreateOperation(userSuppliedState) method... with
userSuppliedState being, more or less, a taskId.
In this case, the userSuppliedState {really taskId} is of the object type,...

I'm building a web server and having some issues with the
TCPListener.Start(BackLog). It doesn't seem to do as expected. I'm using
MS Web Stress Tool to test against my web server and when I see 200
connections at once to it, and I'm seeing 2/3 of the sockets as socket
errors.. They never get into my code, so it has to be failing on the
connection side.. Backlog is the only thing I can think could be the
problem. ...

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:

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,...
