Hello,
Im trying to get the following working but it doesn't seem
to receive anything. I have got the UdpClient class to
receive data but unreliably and was told to use the Socket
class directly. Here's the code:
Dim lep As New IPEndPoint(IPAddress.Any, 0)
Dim s As New Socket(AddressFamily.InterNetwork,

I'm vey new to network programing and have a few rather fundemental questions.
I'm creating a very basic UDP proxy server and having a few issues regarding the sockets. Is it possible to change the properties of a socket WITHOUT closing it and creating a new one?
Basically, I need to change the port of a bound socket, but the only way I have found to do this so far is to close the exisitng socket and create a new one. This in itself...

Hi,
I've developed an application in C# which spawns a thread
to receive datagrams.
If I use the socket receive method, there are no problems
when using the application under NT or XP.
I recently moved over to using the UdpClient receive
method. This was so I could record the IPEndPoint from

It's my understanding of UDP sockets that if there is a thread blocked on a
"recvFrom()" call and other thread sends a UDP packet to some address, that
if the machine on the other end isn't up, that the "recvFrom()" call should
just continue blocking. Right?
What I'm seeing is that when I send a packet to a particular address that is
not responding, my "recvFrom()" call throws an exception. I get "An
existing connection was forcibly...

I have a UDP socket that sends out a request on a multicast socket and waits
for a response. This client is not listening on a multicast IP but the
local IP. The server (UNIX) responds to the sender's IP. Using debug files
on the server I see the server receive the request from my application on my
machine and I see the server send to the correct IP and port of my machine,
but the ReceiveFrom never returns with any data. If I have a...

Does the function below returns an UDP packet, for example, from the
local machine? Why does it give me an error: "The best overloaded
method match for ReceiveFrom... has some invalid arguments". Why this
error?
How can I receive a packet from a specific adapter, for example, my
local machine? Is there a better way? This way won't work. The error is
in "ref ep"... how does receiveFrom work?
Thanks.

Hi, I have an application where a listener thread has a while loop that
just calls Socket.ReceiveFrom over and over. When I close the app by
clickin on the X, the process doesn't die because there is still this
listener thread running. How do I terminate this thread as well?
Thanks

I'm using MS VS C++ .NET. I've written a multicast test utility that can
send IGMP packets for a user specified group address. As well, it can
send and receive UDP packets for a specified multicast group. I'm using
the Sockets Class methods for sending and receiving packets. One area I'm having problems with is recieving IGMP packets on the Raw IP socket.
Here is the main calls I am using to receive IGMP packets.

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
