I am try to evaluate the most efficient method of handling thousands of
simultaneous TCP connects each of which remain connected to the server for
hours and pass a small amount of data usually once a minute. The data
received is logged in a SQL Server database.
The only method I have found of reading each socket requires a thread for
each connection which blocks waiting for data. This appears to be very
inefficient as it will result in...

I've read many articles on the subject and the majority of them give the same
solution that's in article 821625 on the MSDN website. I'm using the
following code and when a the client disconnects the child socket remains in
the CLOSE_WAIT state. Anyone have any idea what's missing?

Hi all,
I am not sure that I am posting this in the right group but here it goes anyway. I am new to socket programming and I have been searching on the internet to the questions I am about to pose but have been unsuccessful in finding the answers so far. Either because my understanding of sockets isn't where it needs to be or my questions are too basic.
My programming environment is Windows XP, Visual Studio .NET 2003 and C#.
So here it...

I read a network programming book (based on framework 1.1) which indicated
that you should 'never' use the RecieveTimeout or the SendTimeout 'socket
options' on TCP sockets or you may loose data. I now see the
socket.RecieveTimeout 'property' in the visual studio 2005 help
documentation (framework 2.0) and it has example of it being used with TCP
socket. This propery is also listed as 'new in .net 2.0'.
1) is the socket.RecieveTimeout...

I'm writing a small asyncore-based server application serving a lot of
clients. When I have to handle more than 1021 client simoultaneously

Hi,
In an attempt to create a full-blown webcrawler I've found myself
writing a wrapper around the Socket class in an attempt to make it
completely async, supporting timeouts and some scheduling mechanisms.
I use a non-blocking approach for this, using the call to 'poll' to
support the async mechanism - rather than the 'begin' and 'end'
functions. I already found that connecting doesn't set the
"isconnected" variable correctly...

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,...
