Body
I am working on a broadcast beacon in C# that is supposed to broadcast server information to all listening devices. The information sent will contain information like the URL of a WCF service, the namespace, a list of required arguments etc. What I have right now is a sender and receiver that can talk perfectly fine when they are on the same computer. However, once I put the sender on another computer than my receiver, the sender sends its message but my receiver never gets it. There are no exceptions being thrown, and the firewall is disabled on both machines. <a href="http://codeidol.com/csharp/csharp-network/IP-Multicasting/What-Is-Broadcasting/" rel="nofollow">http://codeidol.com/csharp/csharp-network/IP-Multicasting/What-Is-Broadcasting/</a> is where I got my code from. Sender: <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Net; using System.Net.Sockets; namespace UDPTest { class Program { static void Main(string[] args) { Socket sock = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); sock.SetSocketOption(SocketOptionLevel.Socket, SocketOptionName.Broadcast, 1); IPEndPoint iep = new IPEndPoint(IPAddress.Broadcast, 9050); byte[] data = Encoding.ASCII.GetBytes("This is a test message"); sock.SendTo(data, iep); sock.Close(); } } } </code></pre> Receiver: <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Net; using System.Net.Sockets; namespace UDPBroadcastReciever { class Program { static void Main(string[] args) { Socket sock = new Socket(AddressFamily.InterNetwork, SocketType.Dgram, ProtocolType.Udp); IPEndPoint iep = new IPEndPoint(IPAddress.Any, 9050); sock.Bind(iep); EndPoint ep = (EndPoint)iep; Console.WriteLine("Ready to recieve"); byte[] data = new byte[1024]; int recv = sock.ReceiveFrom(data, ref ep); string stringData = Encoding.ASCII.GetString(data, 0, recv); Console.WriteLine("Received: {0} from: {1}", stringData, ep.ToString()); sock.Close(); Console.ReadLine(); } } } </code></pre> Does anyone know of anything I am missing that would enable these two to talk on two different computers? They are on the same subnet (192.168.1.x) Thanks Nick Long

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.
