}

In your Layout you should first include jQuery and then jQueryval:
Scripts.Render("~/bundles/jquery");
Scripts.Render("~/bundles/jqueryval");
The reason for this is because the jQuery.validate plugin depends on jQuery and the order of inclusion of your scripts is important.
Also I would recommend you putting all your custom scripts in a specifically dedicated section that is placed after the other main scripts:
Scripts.Render("~/bundles/jquery");
Scripts.Render("~/bundles/jqueryval");
RenderSection("Scripts", required: false)
and then inside your view put all your scripts in this section so that the order is preserved:
#section Scripts {
<script type="text/javascript">
function displaySuccess(result) {
popup.Show();
}
function PrepareValidationScripts(form) {
if (!form)
return;
if (form.attr("data-executed"))
return;
$.validator.unobtrusive.parse(form);
form.attr("data-executed", "true");
}
</script>
}
#{
//this is where I render my partial views
<snip.....>
<snip.....>
<snip.....>
}
Of course the same stands true for your CSS styles. You should place them in a specifically dedicated section in the <head> of the document.

How import file Excel to multiple tables in DB using asp.net and angularJS?

I have developed an application, and in this application I want to import file Excel to multiple table in my DB, and since i am a beginner in angularJS and .NET, I work with .net web api and angularjs, and I develop a function, it works when I import the data into a singe table, but the problem how to import the data into 3 table in DB !!! . and the 3 tables are linked to each other (in my exemple code there 2 table Candidature and Candidat). My question is: how to import Excel file to multiple table in DB and thank's. ( i work with asp.net web API and angularJS )

In your web api, you are expecting two arrays for Candidatures and candidat.
But from your controller you are passing only one array of data excelData.
So when it comes to api it doesn't execute this code,
foreach (var data in candidat)
{
db.Candidat.Add(data);
}
Because candidat is either null or undefined. So it can't go through the loop which the below code is never executed.
db.Candidat.Add(data);

How to implement websockets in Progress OpenEdge?

I'm trying to implement a websocket-server with Progress OpenEdge. I still didn't get it working.
I've successfully created a socket-server with the example i-sktsv1.p from here.
When I run my html-page, which looks like:
<!DOCTYPE html>
<html lang="en">
<meta charset="utf-8" />
<title>WebSocket Client</title>
<script language="javascript" type="text/javascript">
var wsUri = "ws://localhost:3333/";
var output;
function init() {
output = document.getElementById("output");
testWebSocket();
}
function testWebSocket() {
websocket = new WebSocket(wsUri);
websocket.onopen = function(evt) { onOpen(evt) };
// websocket.onclose = function(evt) { onClose(evt) };
websocket.onmessage = function(evt) { onMessage(evt) };
websocket.onerror = function(evt) { onError(evt) };
}
function onOpen(evt) {
writeToScreen("CONNECTED");
doSend("WebSocket rocks");
}
function onClose(evt) {
writeToScreen("DISCONNECTED");
}
function onMessage(evt) {
writeToScreen('<span style="color: blue;">RESPONSE: ' + evt.data+'</span>');
websocket.close();
}
function onError(evt) {
writeToScreen('<span style="color: red;">ERROR:</span> ' + evt.data);
}
function doSend(message) {
writeToScreen("SENT: " + message);
websocket.send(message);
}
function writeToScreen(message) {
var pre = document.createElement("p");
pre.style.wordWrap = "break-word";
pre.innerHTML = message;
output.appendChild(pre);
}
window.addEventListener("load", init, false);
</script>
<body>
<h2>WebSocket Test</h2>
<div id="output"></div>
</body>
</html>
I getting a error that the websocket connection could not be established.
The problem is (I think) that Progress offers a socket, not a websocket. Do you know how to get this working?

How to implement manifest cache for mvc application

Try to create file site.maifest in the root folder of your site. And reference it in your html.
Like this
<html manifest="site.manifest">
Looks that it will be better to create your _Layout.cshtml logic and place common markup there.
I create an example where everything works good. Here it is on GitHub

How do I track SignalR Connection State?

I was pointed to this GITHub sample code by David Fowler himself to track SignalR users and states. I have implemented all of it and it works great except I can't figure out the displaying of Hub connection state changes. I have this which doesn't seem to work. Does anyone know why?
!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<style>
#state {
width: 20px;
height: 50px;
}
</style>
</head>
<body>
<h3 id="msg"></h3>
<div id="state"></div>
<script src="../Scripts/jquery-1.10.2.min.js"></script>
<script src="../Scripts/jquery.signalR-2.0.2.min.js"></script>
<script src="signalr/hubs"></script>
<script>
$(function () {
var userTracking = $.connection.alphaHub;
// Need at least one callback for events to be raised on the hub
userTracking.client.void = function () { };
$.connection.logging = true;
$.connection.hub.stateChanged(function (change) {
if (change.newState === $.signalR.connectionState.connected) {
$('#state').css('background-color', 'green');
} else if (change.newState === $.signalR.connectionState.reconnecting) {
$('#state').css('background-color', 'yellow');
} else if (change.newState === $.signalR.connectionState.disconnected) {
$('#state').css('background-color', 'red');
}
});
$.connection.hub.disconnected(function () {
setTimeout(function () {
$.connection.hub.start();
}, 1000);
});
});
</script>
</body>
</html>
My Hub is shown partially here:
public class AlphaHub : Hub
{
public override async Task OnConnected()
{
try
{
var name = Context.User.Identity.Name;
using (savitasEntities2 entities = new savitasEntities2())
{
var user = entities.SUsers
.Include(u => u.SConnections)
.SingleOrDefault(u => u.UserName == name);
if (user == null)
{
user = new SUser
{
UserName = name,
SConnections = new List<SConnection>()
};
entities.SUsers.Add(user);
}
user.SConnections.Add(new SConnection
{
ConnectionID = Context.ConnectionId,
UserAgent = Context.Request.Headers["User-Agent"],
LastActivity = DateTimeOffset.UtcNow
});
// entities.SaveChanges();
await entities.SaveChangesAsync();
}
}
public override async Task OnDisconnected()
{
try
{
using (savitasEntities2 db = new savitasEntities2())
{
var connection = await db.SConnections.FindAsync(Context.ConnectionId);
db.SConnections.Remove(connection);
await db.SaveChangesAsync();
}
}
catch (Exception ex)
{
c.LogError(ex.Message, "AlphaHub.cs" + " - " + this.GetType().FullName + "." + System.Reflection.MethodBase.GetCurrentMethod().Name);
}
}
Looks like your hubs can't be found.
Change:
<script src="signalr/hubs"></script>
to:
<script src="~/signalr/hubs"></script>
