    <p>First i am n00b in socket programming. So i decided to write simple data over lan tcp server My server code that handles incomming data is</p> <pre><code> private void HandleClientComm(object client) { TcpClient tcpClient = (TcpClient)client; NetworkStream clientStream = tcpClient.GetStream(); clientStream.ReadTimeout = 10; int size = 4096 * 1000; byte[] message = new byte[size]; byte[] All = new byte[0]; int bytesRead; string error = ""; lock (this) { while (true) { All = new byte[0]; while (true) { bytesRead = 0; try { bytesRead = clientStream.Read(message, 0, size); All = AddBArrays(All, message, bytesRead); } catch { break; } if (bytesRead == 0) { break; } } if (All.Length &gt; 0) { Message m = (Message)Tools.ByteArrayToObject(All); OnRecived(new RecivedArgs("localhost", (Message)Tools.ByteArrayToObject(All))); } } tcpClient.Close(); } } byte[] AddBArrays(byte[] ar1, byte[] ar2, int read) { byte[] concat = new byte[ar1.Length + read]; if (ar1.Length != 0) System.Buffer.BlockCopy(ar1, 0, concat, 0, ar1.Length); System.Buffer.BlockCopy(ar2, 0, concat, ar1.Length, read); return concat; } </code></pre> <p>it works but have some issues. It fales receiving files bigger then 100 mbs or smthng and also if i send data very often interval &lt; 800 then data is lost. how should i improve my code? The large file issue is not so important the primary issue is the data loss in fast data sending. tnx for help</p> <p>Ok i now updated the code by the suggestions</p> <pre><code>private void HandleClientComm(object client) { TcpClient tcpClient = (TcpClient)client; NetworkStream clientStream = tcpClient.GetStream(); clientStream.ReadTimeout = 10; int size = 4096 * 1000; List&lt;byte&gt; Test = new List&lt;byte&gt;(); byte[] message = new byte[size]; byte[] All = new byte[0]; int bytesRead; while (true) { //All = new byte[0]; while (true) { bytesRead = 0; try { bytesRead = clientStream.Read(message, 0, size); for (int i = 0; i &lt; bytesRead; i++) { Test.Add(message[i]); } } catch { break; } if (bytesRead == 0) { break; } } if (Test.Count &gt; 0) { Message m = (Message)Tools.ByteArrayToObject(Test.ToArray()); OnRecived(new RecivedArgs("localhost", m)); Test = new List&lt;byte&gt;(); } } tcpClient.Close(); } </code></pre> <p>but the issues still there</p> <p>Edit--> large file issue fixed it was just a 'System.OutOfMemoryException' but it didn't throw a error.</p>

    1. COIs the HandleClientComm method multithreaded...ie...are multiple threads coming in?

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.
