hello,
i've a method in the form_load event witch calls 2 beginread
statements (one after the other :) )
problem: during the second call it seem's that the callback won't be
triggered.
i've tried to wait for several seconds before calling the second call
- no effect.
but (!) if i put the method into a timer event it work's pretty fine.
help!!!
i'm also open for code improvement, if you just say WTF to the
following code:
<code>
public void sendMessage(str ing Message, string LineTerminator)
{
//WAIT FOR FREE CONNECTION
while (Locked)
{
System.Threadin g.Thread.Sleep( 10);
//USED FROM OUTSIDE FOR SYNCHRONISATION
//WAIT STATE
Pending = true;
}
Locked = true;
Pending = false;
msStream = getStream(eCLIE NTS.PARAMETER);
MessageStream msMessage = new MessageStream() ;
msMessage.LineT erminator = LineTerminator + "\r\n";
msMessage.bMess age = new Byte[1];
msMessage.sMess age = new StringBuilder() ;
msStream.BeginR ead(msMessage.b Message, 0, 1, delCallBack, msMessage);
msStream.Write( Encoding.ASCII. GetBytes(Messag e + "\r\n"),
0,Message.Lengt h + 2);
}
private void OnMessageReceiv ed(IAsyncResult asyncResult)
{
MessageStream msMessage = (MessageStream) asyncResult.Asy ncState;
msMessage.sMess age.Append(Enco ding.UTF7.GetSt ring(msMessage. bMessage));
if ( (msMessage.sMes sage.Length >= msMessage.LineT erminator.Lengt h)
&&
(msMessage.sMes sage.ToString() .EndsWith(msMes sage.LineTermin ator)))
{
//extern event
MessageReady(ms Message.sMessag e.ToString());
Locked = false;
ClientConnectio n(eCLIENTS.PARA METER,false);
}
else
{
msStream.BeginR ead(msMessage.b Message, 0, 1, delCallBack,
msMessage);
}
} 1 5333
ignore my question.
i've solved it via trivial synchron write and read commands - never

I have a class that wraps a TcpClient object and manages all the async
reading of the socket. It works really nice, and I use it all over the
place. But there's this ONE INSTANCE where I create one of these things and
it WON'T read data. If I set a breakpoint in my EndRead callback, it never
goes off. NOTHING is different from anywhere else I use this class, its
just this one place.
Now, if I create a second constructor for my class...

Hi all,
I've got a basic TCP app that is giving me trouble. I have a separate
class that takes care of the TCP connection, and uses the NetworkStreams
BeginRead and EndRead with a callback function to deal with the server
response. All works well and the data is received OK. Once all the data
is received, the connection is closed and I fire an event indicating all
is finished. The event is handled in the main form of the application
and...

Hello,
I have a program that asynchronously reads data from a host. However,
whenever I call the BeginRead function, the async reading "loop" never seems
to terminate. Why doesn't the EndRead method return 0 when it is done
reading??
This is the pseudo-code for my callback function:

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.
