    <p>I am trying to read ASCII text response from a tcp open streaming socket</p> <p>This is what I have come up with so far. I want to know what is the best way to do this that includes error handling. Should I also be checking the SocketError after the Receive call in the do loop?</p> <pre><code>IPEndPoint ep = new IPEndPoint(IPAddress.Parse("192.168.1.1"), 9000); Socket sock = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); sock.SendTimeout = 5000; sock.ReceiveTimeout = 5000; if (null != sock) { try { sock.Connect(ep); if (sock.Connected) { // Blocks until send returns. int bytesSent = sock.Send(buffer); Console.WriteLine("Sent {0} bytes.", bytesSent); //get the first 4 bytes, should be the lenngth of the rest of the response. byte[] response = new byte[4]; int bytesRec = sock.Receive(response); int totalBytesRec = 0; if (4 == bytesRec) { int len = BitConverter.ToInt32(response, 0); response = new byte[len]; Console.WriteLine("Trying to get {0} bytes.", len); bytesRec = 0; do { bytesRec = sock.Receive(response); totalBytesRec += bytesRec; forecast += Encoding.ASCII.GetString(response, 0, bytesRec); } while (totalBytesRec &lt; len &amp;&amp; bytesRec &gt; 0); if (totalBytesRec != len) throw new Exception("The total bytes recieved from manager did not equal the expected bytes"); } else throw new Exception("Unable to get the response size from the manager"); Console.WriteLine("Received {0} bytes.", totalBytesRec); } } catch (SocketException ex) { Console.WriteLine("{0} Error code: {1}.", ex.Message, ex.ErrorCode); } catch (Exception ex) { Console.WriteLine(ex.Message); } finally { sock.Shutdown(SocketShutdown.Both); sock.Close(); } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
