sockets

Hi all,
mine appllication communicates with an host via TCP/IP; it reads a writes data on polling through a socket (VB.Net).

If the connection goes outrage, in case of unplugged cable e.g., the read or write operation return me a "false" state and an exception on the socket.
What is the correct operation to do for test periodically the connection, then resetting the last socket and making another istance of the tcpclient?

Any suggested code (VB.net) will be appreciated...
thanks
test the connection, as:

Try
if Socket.Connected then 
Socket.Close
Socket = New TcpClient(..)
Socket.Connect
Catch
socket.close
Socket = new TcpClient
Socket.connect
Finally
