Here's the problem: Suppose we use:

f = some_socket.makefile()
Then:
f.read() is efficient, but verbose, and incorrect (or at
least does not play will with others);

Hi,
I try to implement a reusable socket class to send and receive data.
It seems to work but I have 2 problems :
1) I rely on Socket.Available to detect that the connection is closed (no
more data to expect). Sometimes, Socket.Available returns 0 but the other
end of the connection did not close it !
2) This class will be used by many other classes so I have to use the

My app has an asynchronous socket server. It will have 20 clients connected
to the server. Each client sends data every 500 millisecondsThe Connections
once established will not be closed unless there is a problem with the
connection.
I need to know which client has sent the incoming data as each client has
its own buffer on my "server" app.
I am using the standard asynch socket code from MSDN to listen for
connections and they...

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 need to write an ASP.NET application which can do the following:
1. Create a socket which will stay alive and continously read data.
2. The data read needs to be displayed on the webpage.
3. As the data is received, it needs to be displayed as its received.
I have made an attempt, but hit a problem.
Here is a brief overview of the attempt:

Hello,
Please Help.....
I have been working with some tcp/ip socket communication within a C#
program recently. Basicly, I have a program (myProblemProgram) that has a
socket connected to another program for information passing. Upon receiving
a particular "command" from the the information passing program,
myProblemProgram will launch a separate thread to do individual communication
with another file transfer program. The thread...

Hi,
I've written a class for client-socket connection, but I get a lot of times

restart reading the stream with socket.BeginRead in the Sub

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...

Hi, I'm writing my own implementation of the Gnutella P2P protocol
using C#. I have implemented it using BeginReceive and EndReceive
calls so as not to block when waiting for data from the supernode.
Everything I have written works fine sending and receiving
uncompressed data. But now I want to implement compression using the
deflate algorithm as the Gnutella protocol accepts:
Accept-Encoding: deflate
Content-Encoding: deflate

socket.makefile() may lose data when "connection reset by peer".
and socket.recv() will never lose the data.
change the "1" to "0" in the client code to see the difference.
confirmed on both windows and linux.
so I guess there is a problem with makefile().

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:

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,...
