I'm trying to find a good source for programming sockets with VB.NET. The
examples in the MSDN help do not show how to accept incoming connections and
add this connection to a local array or something similar. Basically, my
application will accept a connection, but the client, after the connection is
accepted, must authenticate; if it does not, the connection is dropped. But,
the sockets are asynchronous and there can be up to 25 different connections,
so I need to know how to differentiate between them. Any ideas on a good
book?

I highly recommend as I use them for teaching:
1) MS-Press Network Programming for the Microsoft .NET Framework; by
Jones/Ohlund/Jones; ISBN 0-7356-1959-X
It contains one of the best explanations of streams btw.
2) Wrox, Professional .Net Network Programming, ISBN 1-86100-735-3
(or look at Apress if Wrox doesn't offer it any more)
This is more difficult to read, yet goes into more details.

Hello everyone,
I have a vb.net application that wraps the TCPListener object
in a class. The server connects to the local interface and establishes
itself on port 9900. It then polls for pending connections every 500ms.
I also have a vb6 application that uses the WinSock control at the other end
of the communication tunel. I have to work with vb6 here because it uses
less memory than .NET.

I am (attempting) to move an existing socket application to use raw sockets.
Right now, my application is essentially a port forwarder. Upon receiving a
connection, it will open a connection to an "internal" server and simply
relay all information back and forth (when the client sends something, my
app sends that to the server, when server sends something, my app sends that
to the client).
While what I have right DOES work, 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.

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,...
