Hi,
I am using a tcpclient and a tcplistener to send and receive packets. The
client sends a packet and the listener replies with another one. I can send
2 packets and get an answer from the listener but it fails to send a third
packet. I don't get any error messages. The client sends the packet
successfully but it never arrives to the listener. This only happens when I
send the packets one straight after the other. If I place a delay of 2...

Hi,
I'm writing a client/server application in which the client send a series of
screenshots to the server to be saved using the tcpclient.
in most cases the first screenshot is transmitted ok and arrives at the
server but from after that i only a couple of KB from the start of the file
which cases the picture to display only the very top (of the screen).
All the pictures are saved at the client side before sent to the server and

What is wrong here?
IPAddress ipAddress = IPAddress.Parse("10.10.20.1");

this.tcpClient = new TcpClient(ipEndPoint); // PROBLEM HERE
=> Exception: "The requested address is not valid in its context"
This works:

i had a problem whom i do not know how to explain.
i was using a TcpClient (System.Net.Sockets.TcpClient) object to send and
receive data to an AS400 socket. Two months ago it started to work slowly,
about 4 seconds between send and receive. In our production environment with
hundreds of transactions it was truly costly.
a while ago i changed de TcpClient object. Now i am using a Socket
(System.Net.Sockets.Socket) object and it...

Hi all,
I'm trying to send a null character as a string delimiter through a
TcpClient (code below). It's to connect to this poker bot room:
http://games.cs.ualberta.ca/webgames/poker/bots.html
My code is as below, but I never get a response. I'm assuming my
transmission is ending at the null character (the debug statement certainly
only outputs up until the null character). Any ideas?

Hi All and Happy New Year ;)
I have a very strange problem with System.Net.Sockets.TcpClient().
For some reason, the number of bytes I can receive is limited to 5460 bytes.
I made sure that the server really sends everything I expect it to send. I
am actually sending XML messages and this limit is a pain in the ...

I am having trouble using the TcpListener and TcpClient classes.
At the end of this post is server code that runs, and a class whose purpose

First I asked MSDN and they said..

I'm creating a TcpClient instance in an object which is created in a
thread.
I have a loop that goes about 6-7 cycles, creating the container object
in each cycle and each object contains a TcpClient instance.
If I run this loop without threading everything goes find. But if I do
it within the thread, invariable on of the threads will fail to
connect.

from msdn the eventual obtainment of machine name and port number.
Please suggest a solution.

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:

With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.
