Context:
C#
System.Net.Sockets
Socket created with constructor prarmeters Internetwork, Stream and TCP
everything else is left at the default parameters and options except linger
may be changed as I find appropriate.
I am using the socket asynchronously by calling the BeingSend and
BeginReceive calls. I would like to be able to call shutdown and close
asynchronously if possible.

How to trap browser close event in SERVER side?
I read a lot of forum message, it talk about onclose(), onunload() and even
onbeforeunload() event. However, all of theses are based on javascript
written on the client browser , like IE. To send a POST to web server to
acknowledge its close event.
However, I just think, web server and client browser is a TCP connection.
And if the client browser is close and it imply the TCP socket is...

I am currently implementing a singleton pattern for accessing a
database. Is it advisable to close the connection to the database at
all -- thus leaving it open or should it be closed. If closed, when
should I it close it -- after the execution of the each command to the
database? If leaving open, what impacts does it have. Imagining that
it is one connection to the database.
Thanks,

According to HTTP/1.1 specs, a client should only have two connections open
to the host at a time (which can be changed by browser users, of course).
When using xmlHttpRequest connections, is there any way to detect that the
request is queued?
I did some tests (see "Queued Requests" at
http://www.ajaxtoolbox.com/request/examples.php ) and it looks like
readyState 1 is fired immediately after the request is made, even though
it's not...

Hi,
In one of my pages, I use javascript (AJAX) to populate one mulitple
select field based on user's click event on another control. I noticed
that when I navigate back to this page by clicking browser's "Back"
button, the changes made to the multiple select is not preserved. (It
shows the initial value). While all the other user selections are
preserved.
Firefox seems fine.
How do I workaround this issue for IE?

I have a sync socket application. The client is blocked with
Socket.Receive(...) in a thread, another thread calls Socket.Close(). This
unblock the blocked thread. But the socket server is still connected. Any
idea?
Thanks.

Greetings! I was researching AJAX to provide a solution to displaying status
messages while a long process executed. I found several examples online and
was able to use their code to get a quick application working. However, when
attempting to implement the solution, the AJAX calls weren't updating the
screen like the examples were and seemed not to fire until after the long
running process had completed.
I found the only real...

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,...
