I'm facing a problem where I need to verify that my windows forms application has access to the internet before it can do anything. Currently, the only way I can think of is by creating a HttpWebRequest and point it to the specified URL I wish to connect to later on, and if that throws an error, I know I don't have an internet connection. Is this the best method for detecting an internet connection, or is there some sort of routine that I need...

Hello, everyone. I just began school, and they
already assigned us science fair. Since I'm in 8th
grade, I get to do demonstrations for our projects.
I'm probably going to demonstrate Python's networking
capabilities by writing a simple instant messenger
program. I only have a few problems:
1. I know squat about Python network Programming
2. I know nothing about networks

Hi All
I'm writing scripts in VBS fore years. But now I've to
write a tool in Visual Basic .Net which has to connet to a
Windows domain. I know how to do this in VBS but I don't
find a way in VB.Net. I've no idea how to logon to the
domain via Net.Socket. It is not necessary to map a
network drive. I can transfer data via UNC names.
Can anybody give me a suggestion how to realize it?

Ok, I know this has been asked hundreds of times before (though for .net CF
1.0), but I want to detect when wired and/or wireless connections are made
or broken from within the .net CF 2.0 (the physical connection).
I have done something similar in 1.0 using ConnectionManager which would
connect if a connection was available and throw me an event when that
connection died, but is there anything new in the new framework?
I have looked...

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...

Here's the problem...if a client does not gracefully disconnect (unplug the device from the network or a power failure), my server does not recognize the lost connection and just continues to wait to receive data.
Any help would be great, I have been searching online for a...

Hi group,
I've written a client/server application, using the dotnet sockets.
In my server, I have a thread waiting for messages with :
ret = currSocket.Receive(buffer, 1024, SocketFlags.None);
When the client exits, I close the socket with a specific message
(like "end") and the thread terminate in a proper manner, but If my
client crashes, the server is still waiting for receiving data, and

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,...
