Is there a known bug with the interaction between the HttpWebRequest and the
ThreadPool? I current spawn several HttpWebRequest's using
BeginGetResponse, and they work for a while, using worker threads from the
ThreadPool. However, eventually (relatively quickly) there become fewer and
fewer available worker threads in the pool, until there are 0 and a
System.InvalidOperationException occurs with the message: "There were not
enough free...

I'm looking for someone to help me make sense of the results I'm observing when using the ThreadPool class in a COM-Interop scenario. Here's the set up:
1.. A classic ASP page instantiates and calls MethodA on COM+ Class (C1).
2.. MethodA of COM+ class (C1) instantiates and calls MethodB of .NET class (N1). (Note: N1 has been registered using RegASM and is present in the GAC).
3.. MethodB of .NET class (N1) uses the...

Why microsoft make so hard to change the max Pool Size??
I really need to change it to 50, because I'm using delegates with
BeginInvoke and I saw that they (delegates) use the ThreadPool, but I saw
too that is very complicate to change the ThreadPool size and if I want, I
need to use unmanage resources

Hello group:
I have a quick question.
Background:
I have an assembly that is responsible for handling our clients' *requests*
(not a webservice/http request per se but our concept of a request --
meaning 'request for our service') thru our webservice. Depending on the
type of client request, we may have to contact an outside provider thru a
WebRequest/WS-method, DCOM, etc... The way it works currently is to handle

Hello,
I have always used a certain design pattern for multithreaded Windows app;
Start new worker thread from UI thread, use events to notify UI threads when
something happens, update UI controls using delegates through .BeginInvoke. I
came across some code samples recently where ThreadPool class is used to
start new threads.
My questions;
1. what's the difference?
2. Any performance benefits?

I am trying to create a page where multiple requests are made to a single
webservice. This webservice takes a fair amount of time to process the
requests so rather than making the calls one at a time I'd like to create a
new thread for each call. I tested this in a stand alone application with no
problems at all.
My problem is that when I try using the System.Threading.Threadpool class
inside the aspx page, nothing happens. I add a...

Hi,
I have a .NET class which uses the .NET threadpool (using QueueUserWorkItem)
to create about 8 threads, which do some work while the parent thread waits
for them all to complete, which works fine when referenced from a normal EXE.
When I reference this DLL in a webservice however, the threads seem to be
created one by one in order, rather than at the same time - it is as if there
is only one available thread in the ThreadPool and the...

Hi All,
I'm currently developping something where I need to use threads.
Here's the basic scenario. I have a WebService requests which need to
launch a few threads and wait for them to complete before returning a
responses. Bascically, each thread will make a request to our old C++
server and wait for the answer before completing. Also, the WebService
request thread will wait until all the server requests thread are
completed ( or...

Hello everybody,
I'm programming a TCP server.
During the stress tests I noticed that maybe my socket-receiving thread
became deaf after an hour of heavy stress.
I think that the reason could be this: The processing of the received
messages. Something goes wrong in this processing and the code gets stuck
here. As the processing is within the receiving "while" loop, the loop gets
also stuck, so that we will never reach again the...

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:

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,...
