Is there a way to be notifyed (callback, event,...) when the connection of
socket was closed... The WinSock activex in vb6 had event ondisconnect...
I get exception when i try to send some data, but i need disconnect info
sooner.
I have a solution with timer that checks the state of socket, but i don't
like to use timers...

If you have a pending read waiting on the Socket, it will fail with an
exception when the socket is closed. That should give you more timely
notification about the disconnection.

Thanks for response Will,
I found a sample class, that uses frameworks socket class and exports itself
with events and methods like WinSock.ocx in VB6. I looked up how the
disconnect event was raised:
The class uses async callbacks for reading the data, and when you call
EndReceive function on callback, the return value is BytesRead. If you get 0
bytes, the disconnect event is raised.

You should catch and handle the exception (fire your own event if you
need to). You will also note that a socket can be closed _during_ a
send or read operation. In fact, you should handle all exceptions.

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?

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.

Unfortunately, with .NET Framework 1.1 I have no way to close a

resources altogether (i.e, Socket.Close()),...

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 am having a problem on handling asynchronous sockets in C#. I
implemented a pair of client and server sockets. The connection is ok when
first connected. However, when I turned off the server socket, the client
is able to connect, but cannot send anything out. It seems that the
Socket.Connected is false but I received no disconnection event. Any idea
on how to solve the problem?
Thanks.

a spike in nonpaged pool memory just prior to the crash each time.
We finally think we have narrowed down the cause of this to a user (located
semi-remotely) who would connect into our system and disconnect
"ungracefully" (literally, by pulling his network cable). Connections here
are all...

Hi,
We have an asynchronous server socket program, which works fine BUT, when due to some circumstances, I receive null data or blank data, the server goes to infinite loop
Here is the code

{
public class StateObject //class created to clear the duplicate records

// Client socket.

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.
