Hi,
I'm implementing an asynchron socket Receiving method and I have a
question about EndReceive.
Read()
{
Socket.BeginRec eive(buf,0,buf. Length,0,new
AsyncCallback(R eadCallback),dp );
}
ReadCallback(IA syncResult asyncRes)
{
...
int bytesRead = Socket.EndRecei ve(asyncRes);
...
}
My question is now, what happens if I try to receive a datapacket
which is greater than the buffer buf? EndReceive returns when when the
buffer buf is full. Can I call EndReceive again? or should I restart
Read()? But how can I know that there are datas waiting for reading?
Thanks

Hi, EndReceive returns when when the buffer buf is full.
No, it may retrun less bytes than buffer, because of it ALWAYS see hwo much
int bytesRead = Socket.EndRecei ve recived.
Can I call EndReceive again? or should I restart
No, you must start from BeginRecieve again
Read()? But how can I know that there are datas waiting for reading?
You don't need to know that, BeginRecieve waits data to arrive.

Spent some very frustrating hours recoding to find a way of closing a server
socket, i'd not thought it would be any problem,
however, after complete failure and as a last resort, i looked at the python
wrapper module for sockets, and found that the close command doesn't actually
call the underlying close! this didn't seem right, so i added it, and my code
now works simply and as expected.

I have a Socket based application using the asynchronous Sends and Receives
of the Socket class. I send out XML strings using BeginSend/EndSend from a
client end point, the server side does a BeginReceive/EndReceive.
I knew a message could be split up between Receives and I look for an end of
message marker (and continue receiving if not there) before processing the
complete message. However I was told (on this board I think) that I would...

Hello,
I am running into a problem with Asynchronous socket communication. I
am developing a simple telnet client to interact with unix. I am
parsing received data for prompts and sending data on found. Problem
is, that sometimes EndReceive returns only a few bytes, much less than
what is in the buffer. Since I am parsing what is in the buffer up to
how large bytes received is, I end up skipping data. Odd thing is
that it works 1/2...

I'm creating a system wide (distributed) Publish/Subscribe Event Broker using
..NET Sockets as the transport mechanism. I'm doing all my
connects/accepts/sends/receives
asynchronously (well, not all, but thats beside the point really). I also
have an EventBroker that all clients connect to and the EventBroker holds the
open socket connections to communicate with. My problem is, how do I know
when my EndReceive call has finished a message?...

Hi,
I have a socket that always seek for incoming data.
Between Point A and Point B, the socket (mySocket is closed and assigned
to nothing in another part of my program (happen when a connection is
broken). So regurlarly when a socket is closed, it create an error
somewhere in this routine, even if I check if the socket is nothing or
not, and connected or not (I also tried to check before doing the
beginreceive)

I am having mixed results with asynchronous socket receives.
Sometimes I get the right information back from the buffer, other
times I get some of the data that should be in the buffer printed out
to the console. That data is printed out to the console before I even
call Socket.EndReceive(). After that call, I get the rest of the data
that wasn't printed out to the console in the buffer. Anyone have
any idea what is going on?

I have a C# Socket configured for streaming TCP. Upon making a valid
connection, I have an asynchronous callback configured using
BeginReceive. Within the BeginReceive declaration, I set the socket
flags to SocketFlags.Partial to allow my callback to be invoked as
soon as it arrives rather than waiting for the receive buffer to fill
up.
The problem I am having is that when I invoke the

Hi, I'm trying to write a receive loop in my socket class that will receive what data is in the buffer, call an event to let the user know that there's new data, and then receive the rest of the data. It kinda almost works; it receives much of the data, but seems to miss the last packet or two. Here is the code in the loop:
