    <p>Hi I am trying to send a simple HTTP message from Flex to C# server, but it seems that I am getting tow calls, first is the real one and the second is an empty one.</p> <p>Why is that and how can I handle it?</p> <p>This is my C# code:</p> <pre><code>TcpListener listener = new TcpListener(IPAddress.Any, 9400); listener.Start(); Console.WriteLine("Server started"); Socket client; while (true) { client = listener.AcceptSocket(); // client.Available is an expensive call so it's just for testing Console.WriteLine("Client accepted " + client.Connected + " " + client.Available); SocketHandler handler = new SocketHandler(); ThreadPool.QueueUserWorkItem(handler.handleSocket, client); } </code></pre> <p>this is the SocketHandler:</p> <pre><code>public void handleSocket(object socketObjeck) { try { socket = (Socket)socketObjeck; byte[] buffer = new byte[1024]; SocketSettings.setSocket(socket); //blocker... try { socket.Receive(buffer); } catch (Exception e) { Console.WriteLine("Error\nFaild reading from socket\n" + e.Message); socket.Close(); return; } parseData(buffer); socket.Close(3); } catch (Exception e) { Console.WriteLine("Error\nError \n" + e.Message + "\n" + e.StackTrace); } } </code></pre> <p>And this is my flex code:</p> <pre><code>var request:URLRequest = new URLRequest(); request.data = "Hello from flex"; request.url = URL; request.method = URLRequestMethod.POST; loader.load(request); </code></pre> <p>I am always getting 2 calls. The line:</p> <pre><code>Console.WriteLine("Client accepted " + client.Connected + " " + client.Available); </code></pre> <p>called twice. What am I missing?</p> <p><strong>Edit 1:</strong> I can tell you for sure that the second call is empty, it's not even seen in chrome JavaScript console, it's like flex opening a connection, and waiting for some response or I don't know what... but it sending no data.</p> <p><strong>Edit 2:</strong></p> <p>I been trying to send a true HTTP response a notice another thing, the second call is coming without waiting for the first call, if I am putting the response thread to short sleep(100 milliseconds in my test) then I am getting the second call before I been able to response for the first one.</p> <p>P.S Using Flex 4.6, Visual Studio 2010</p>

    1. COWhy not have a look at the client end at what is actually being requested? Firebug, Fiddler or Charles will all be able to do this.

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.
