I have a program that launches multiple threads with a ThreadStart
method like the following (using System.Net.Sockets.Socket for UDP

Below you'll find the code i'm working on.
It's in a button click routine and hangs after 3 or 4 sometimes 5 loops
done, probably in sock.receive(....).
Some code was found here( on google i mean) but the amazing( at least for
me) is that if i run the program step by step or i cancel the loop and run
it by pressing the button again and again it never hangs .
I want to have an infinite loop so my socket keeps on listening until i...

Hi
I listen on a port, when data is received I raise an event
(OnMessageReceived) in the while loop as follows:
private void WaitForConnection() {
TcpListener listener = new TcpListener(IPAddress.Any, 1234);
Stream data = null;
Socket socket = null;

I have 2 projects - 1 Winform project that sends Udp messages using the
UdpClient class when a button is clicked, and a Console application that
listens for these Udp messages.
If I try to use the UdpClient class to receive, it never works. The messages
are never received (no exceptions). If I use a normal socket configured to
listen for Udp messages, it works perfectly.
Below is my sample code. It is only test code - I know the...

My socket application blocked at socket.receiver() after received all
information from sender. Should socket.Receive() return 0 after no
more data available? Note: My socket object was not close on both
client/server side. My cached for further use.
While bytesReceived > 0
byteBuffer = New Byte(1024) {}
bytesReceived = handler.Receive(byteBuffer)
If bytesReceived > 0 Then
ReDim Preserve m_data(bytesTotalReceived + bytesReceived - 1)

I'm using Microsoft's own VB.NET FTP Example:
http://support.microsoft.com/default.aspx?scid=kb;en-us;832679
I can get the program to create directories, change directories, etc.,
but I can't get it to upload a file to the FTP server. I just get a
"Cannot connect to remote server" error after this TRY:
s = New Socket(AddressFamily.InterNetwork, SocketType.Stream,
ProtocolType.Tcp)

I am building a data backup application in C# using Sockets. It has a server component and a client component. The client is going to upload files to the server through TCP sockets. I've got all figured out and have been able to transfer files between client and server. Now I have some doubts about which is the best method to transfer a file? Option 1 - I use the built in Socket.BeginSendFile (I am using async calls) to transfer a file. Option 2...

Hi,
My understanding is that for the same socket, assuming send and receive run
at two different threads, I have to use BeginReceive to avoid the blocking on
send part. However, I can jsut use Send without worrying about any threading
issue in case send and beginreceive happens at the same time on the socket?
Am I correct on this?
Thanks

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:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
