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...

I have created a piece of code that uses a ThreadPool class and the
QueueUserWorkItem method to add items to the the ThreadPool. What
would seem to be simple I just can not figure out how to tell if all
of the threads in the threadpool that I queued have completed. Does
anyone have a way???? Any help would be appreciated.
Thanks,
Scott

Hi,
I see in the ThreadPool documentation that the pool has a default limit of
25 threads.
Is it correctly understood that this limit is for my entire application? So
if I have several worker-threads each using "ThreadPool.QueueUserWorkItem"
then the limit is spread over all my worker-threads - so if
"worker-thread-1" currently has 20 calls in progress then there are only 5
thread-pool threads available for "worker-thread-2" ?

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?

It occurs to me that if I have a work object that gets executed via
QueueUserWorkItem AND the work proc accesses only that object's
instance data I STILL may have to lock because the object constructor
ran in a different thread. That therefpre means that without a lock
the threadpool thread might not get the correct view of the instance
data. (Specifically, it might still be seen as null).
Has this ever come up before?
Thanks,

Might sound a stupid question but need to be sure:
When you call ThreadPool.QueueUserWorkItem and
ThreadPool.RegisterWaitForSingleObject passing a New object as state
e.g.: ThreadPool.QueueUserWorkItem(AddressOf MyCallBack, New
MyObject(myArg1, myArg2))
the new object MyObject is instantiated just before QueueUserWorkItem is
called, and not just before MyCallBack is called, isn't it?

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...

I've written a c# web service. When a request is received I need to download
a potentially large file from another site. To do that I was starting a new
thread using QueueUserWorkItem but to my surprise the thread frequently
vanishes before finishing it's task. Why?
If I use system.threading.thread to create a thread instead of threadpool,
will it suffer the same fate? Is there any downside to that approach. Other
alternatives before...

This question is prob. extremely trivial but I can't seem to find out
what is going on. I've been doing some basic work with Multithreading
and Worker Threads and have determined I'd like to set up a minor
project that has ThreadingPools.
I can't seem to get it to compile whether I follow the example
tutorials or I don't. Of course the latter has a higher percentage of
failing :)
Anyways the line that fails is:

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...

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,...
