:0 TCP foobox:8888 localhost:2189 TIME_WAIT
:0 TCP foobox:8888 localhost:2190 TIME_WAIT

Using the TcpListener and TcpClient I created a program that just sends and
receives a short string - over and over again. The program is fine until it
gets to around 1500 to 1800 messages. At that time, I get a SocketException
with the message "Only one usage of each socket address (protocol/network
address/port) is normally permitted". This happen if you use localhost or
between two distinct computers. And, for a period of time after the...

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

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...

it is very strange for me that a simple event of closing socket that was in
the the winsock object of vb6 ,
i didn't found yet in the vb.net
the only way i found is to try to send something to the socket and if i got
error then the socket is closed.
there must be a way to get this event without trying to send something ,
since it is in the lower level

i am working on basically a proxy server that handles requests via remoting
from clients and executes transactions against a third-party server via TCP.
the remoting site works like a champ. my problem is executing the
transactions against the remote server and returning the response to the
remoting client. i can open the socket fine and, if i am executing one
transaction at a time, everything works great. it's when my proxy server...

I am just beginning to learn about the TcpListener and TcpClient and Socket.
I have figured out the TcpListener, it is used for booth in and outgoing
requests, right?
But when to use the TcpClient and when to use the Socket?

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,...
