Associated with each of these socket components are socket objects, which represent the endpoint of an actual socket connection. The socket components use the socket objects to encapsulate the socket server calls, so that your application does not need to be concerned with the details of establishing the connection or managing the socket messages.
If you want to customize the details of the connections that... more

Getting Information About the Client or Server Socket Connection 

After completing the connection to a client or server socket, you can use the client or server socket object associated with your socket component to obtain information about the connection. Use the LocalHost and LocalPort properties to determine the address and port number used by the local client or server socket, or use the RemoteHost and RemotePort properties to determine the address and port number used by the remote client or server socket. Use the GetSocketAddr method to build a valid socket address based on the host name and port number. You can use the LookupPort method to look up... more
