    <p>I wanted a very simple WebSocket sample in .NET 4.5 but haven't been able to get any examples/tutorials working. I'm beginning to think it's actually my system rather than the samples (some of them are out of date, referencing W8 RC, for example). So I'm trying to find out where something is not happening. I'm struggling to find the linkage between the client and server methods. For reference, I'm on a new install of Windows 8 Ultimate with all updates current, developing on VS2012 Ultimate with all updates current, using Firefox 23.0.1 and IE10.0.8.</p> <p>The client below prompts for the username, allows the user to enter text, and clears the text after clicking the Send button. The server OnConnect fires after the user has entered their username - but that's all. The OnDisconnect never fires but that might be the client not terminating nicely. The Send method is never called - is this what chat.server.send() is supposed to call (even though the casing is different (doesn't change the outcome if I match them anyway))?</p> <p>The Firefox network debugger shows periodic outbound GETs but nothing when clicking on the Send button. The referenced scripts seem to be ok.</p> <p>Apologies for the long post: inevitably I've still forgotten something pertinent!</p> <p>HtmlPage1.html:</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;html&gt; &lt;head&gt; &lt;title&gt;SignalR Simple Chat&lt;/title&gt; &lt;style type="text/css"&gt; .container { background-color: #99CCFF; border: thick solid #808080; padding: 20px; margin: 20px; } &lt;/style&gt; &lt;/head&gt; &lt;body&gt; &lt;div class="container"&gt; &lt;input type="text" id="message" /&gt; &lt;input type="button" id="sendmessage" value="Send" /&gt; &lt;input type="hidden" id="displayname" /&gt; &lt;ul id="discussion"&gt; &lt;/ul&gt; &lt;/div&gt; &lt;!--Script references. --&gt; &lt;!--Reference the jQuery library. --&gt; &lt;script src="/Scripts/jquery-1.6.4.min.js" &gt;&lt;/script&gt; &lt;!--Reference the SignalR library. --&gt; &lt;script src="/Scripts/jquery.signalR-1.1.3.js"&gt;&lt;/script&gt; &lt;!--Reference the autogenerated SignalR hub script. --&gt; &lt;script src="/signalr/hubs"&gt;&lt;/script&gt; &lt;!--Add script to update the page and send messages.--&gt; &lt;script type="text/javascript"&gt; $(function () { // Declare a proxy to reference the hub. var chat = $.connection.chatHub; $.connection.hub.logging = true; // Create a function that the hub can call to broadcast messages. chat.client.broadcastMessage = function (name, message) { // Html encode display name and message. var encodedName = $('&lt;div /&gt;').text(name).html(); var encodedMsg = $('&lt;div /&gt;').text(message).html(); // Add the message to the page. $('#discussion').append('&lt;li&gt;&lt;strong&gt;' + encodedName + '&lt;/strong&gt;:&amp;nbsp;&amp;nbsp;' + encodedMsg + '&lt;/li&gt;'); }; // Get the user name and store it to prepend to messages. $('#displayname').val(prompt('Enter your name:', '')); // Set initial focus to message input box. $('#message').focus(); // Start the connection. $.connection.hub.error(function (error) { console.log('SignalR error: ' + error) }); $.connection.hub.connectionSlow(function () { console.log('We are currently experiencing difficulties with the connection.') }); $.connection.hub.start() .fail(function(){ console.log('Could not Connect!'); }) .done(function () { console.log('Now connected, connection ID=' + $.connection.hub.id); $('#sendmessage').click(function () { // Call the Send method on the hub. chat.server.send($('#displayname').val(), $('#message').val()); // Clear text box and reset focus for next comment. $('#message').val('').focus(); }); }); }); &lt;/script&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>Global.asax.cs:</p> <pre><code>using System; using System.Web.Routing; namespace WebSockets2 { public class Global : System.Web.HttpApplication { protected void Application_Start(object sender, EventArgs e) { var hubConfiguration = new HubConfiguration(); hubConfiguration.EnableDetailedErrors = true; RouteTable.Routes.MapHubs(hubConfiguration); } protected void Session_Start(object sender, EventArgs e) { } protected void Application_BeginRequest(object sender, EventArgs e) { } protected void Application_AuthenticateRequest(object sender, EventArgs e) { } protected void Application_Error(object sender, EventArgs e) { } protected void Session_End(object sender, EventArgs e) { } protected void Application_End(object sender, EventArgs e) { } } } </code></pre> <p>ChatHub.cs:</p> <pre><code>using Microsoft.AspNet.SignalR; using System.Diagnostics; namespace WebSockets2 { public class ChatHub : Hub { public override System.Threading.Tasks.Task OnConnected() { Debug.WriteLine("Connected"); return base.OnConnected(); } public override System.Threading.Tasks.Task OnDisconnected() { Debug.WriteLine("Disconnected"); return base.OnDisconnected(); } public override System.Threading.Tasks.Task OnReconnected() { Debug.WriteLine("Reconnected"); return base.OnReconnected(); } public void Send(string name, string message) { // Call the broadcastMessage method to update clients.

    2. COIt's on localhost (trying to keep as simple as possible!). I've added logs from IE (can't seem to get them out of FF but I assume the output would be the same). Am trying to get server end logs...

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
