Hi,
I am trying to call a function in my web page, asynchronously, to improve
performance. I am using a function delegate to do that. I have a web page.
When the user clicks a button, i want to execute this function
asynchronously and in the meantime move on to other tasks. At the very end,
i call EndInvoke. Problem is if i disrupt this process by closing the
browser Visual Studio "freezes" and won't become active until after some
time....

Hello,
I am experimenting with async callbacks using BeginInvoke and EndInvoke, and
although my code which I have shown below works, when the program stops at
the end (on the ReadLine()), there are still 2 threads running if i pause
the execution, even if I kow that EndInvoke has been called on the thread.
This also happens in the async callback sample on msdn. Is this anything I
need to wory about, because it doesn't seen too good to...

I've been working on some samples that use BeginInvoke/EndInvoke. In one
example, I call BeginInvoke and pass it an AsyncCallback function pointer.
I was messing around with ReaderWriterLocks and noticed that if I did this,
it worked (please ignore the lack of try ... catch blocks, because I cut
down the code to be more brief - I have a try...catch surround the
AcquireWriterLock method):
----------
myLock.AcquireWriterLock(1000);...

I can start an Asynchronous operation against a data source with
SQLCommand.BeginExecuteReader, allowing me to loop, checking for user
cancellation before the operation has completed, but how then to cancel the
SQLCommand if the user wishes to? The "Cancel" method states:
".......... The Cancel method cannot be used to cancel a pending
asynchronous operation."
The scenario I'm thinking about here concerns a potentially long-running...

Hi all,
someone know if I can use the IAsyncResult.IsCompleted Property of
IAsyncResult that return from Socket.Beginxxx methods to determine if the
Endxxx method already called perior or not ?
I have methods that return the IAsyncResult after I called begin... (connect
for example)
and I want to know if I should call the EndConnect or not outside the
method.
Thanks

Hello All,
I would like to know how I can process a non-CPU bound operation in an
asynchronous fashion so that the original thread is returned to the thread
pool? Fritz Onion wrote a very interesting article on asynchronous handlers
but handlers may not be suitable for my requirement.
http://msdn.microsoft.com/msdnmag/issues/03/06/Threading/default.aspx
Does anyone know of articles that discuss how to perform a lengthy operation

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,...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
