Server responded with 404: Not Found for localhost/undefined

I have been scratching my head for days. I've googled to no avail. I am trying to get stuff from a database with jquery.ajax, based on the information I send over (sorta a post AND a get) everytime though, the server responds with an Error 404: Not Found, and is telling me I asked for Localhost:1986/undefined, which is not the case.
I'm sure exactly where all my folders and files are is important, so I will include as much as I can, feel free to ask for more if it is necessary.
My script is copy pasted and modified from another script I have to post to the database, and that works fine, so why this one doesn't stumps me:
function nextSlide() {
var articleLink = document.getElementsByTagName("a")[0];
$.ajax({
type: 'POST',
url: "../SlideShow/NextArticle",
data: {
slideID: articleLink.getAttribute("id"),
},
success: function (result) {
$(articleLink).id = result[0];
document.getElementById("articleImage").setAttribute("src", result[1]);
document.getElementById("articleTitle").innerHTML = result[2];
document.getElementById("articleText").innerHTML = result[3];
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert("Status: " + textStatus); alert("Error: " + errorThrown);
}
});
}
This is the method inside my SlideShowController.cs file I am trying to use:
[AcceptVerbs(HttpVerbs.Post | HttpVerbs.Get)]
public JsonResult NextArticle(string slideID)
{
int ID = int.Parse(slideID);
var articles = db.Slides.ToList();
var currentArticle = db.Slides.First(s => s.SlideId == ID);
int articlePosition = articles.IndexOf(currentArticle);
articlePosition = (articlePosition + 1) >= articles.Count() ? 0 : articlePosition + 1;
var nextArticle = articles.ElementAt(articlePosition);
//nextArticle.Article.ArticleText.Substring(0, 50)+"..."
string[] returnParameters = {
nextArticle.SlideId.ToString(),
nextArticle.Image.ImageURL,
nextArticle.Article.ArticleTitle,
nextArticle.Article.ArticleText
};
return Json(returnParameters);
}
The SlideShowController.cs file is inside a folder named Controllers in the root directory. The script is called from a _SlideShowPartial.cshtml file in a Root/Views/SlideShow folder. That file is loaded in a Index.cshtml file in a Root/Views/Home folder using #html.Partial()
Here is a screenshot of the error that appears in chrome console:

You're definitely sending url wrongly to the server. try a complete url, or remove url from your $.ajax query.

Consider introducing T4 MVC into your project. This will give you strongly typed access to MVC actions and let you avoid URL strings which looks like your issue here.

ASP.NET Login Not Reading Connection String

This is probably a noob question, I am new to ASP.NET Login controls. The problem is, the login page loads and you enter the username and password. However, it always says "Your login attempt was not successful. Please try again." That prompted me to see if it was even hitting the db. It is not, because this is the connection string as you can see below:
connectionString="Data2121212 Source=20e2127213597;Initial Catalog=ramsl323312sanddb;User Id=ramsl1342anddb42o;Password=r13zzzzzzbs;"
Even with that connection string which is completely invalid it throws no error. So obviously its not even trying to connect. What I can't figure out, is why is not connecting. I was told that the login control would just read the web.config file and pick up the connection string etc. But its not. Can someone please explain to me whats going on?
And yes, the site is using that config file.
<connectionStrings>

Try putting the following line in:
So your new connection strings settings should look like this:
<connectionStrings>
<remove name="LocalSqlServer"/>
<add name="LocalSqlServer" connectionString="Data2121212 Source=20e2127213597;Initial Catalog=ramsl323312sanddb;User Id=ramsl1342anddb42o;Password=r13zzzzzzbs;"/>
</connectionStrings>
now for as long as your Database has the ASP.Net database in it with a user account it should work perfectly fine.

I got it! My noob client coded the login control all wrong apparently, because when I used a new one, it worked great!
Also, great tips here for anyone who has an issue like this:

by reading the above config file i need to change the attribute value of type field in membership providers nodes.
type="System.Web.Security.SqlMembershipProvider"
to new value
type="sample.SqlMembershipProvider"
through c#.net lambda expressions
waiting for your responses

I done the solution as
var xDoc = XDocument.Load(inputPathToConfigFile);
var ns = xDoc.Descendants().First(x => x.Name.LocalName == "configuration").Name.Namespace;
var prop = xDoc.Descendants(ns + "membership")
.First(p => p.Attribute("defaultProvider").Value == "SQLMembershipProvider");
if(prop.HasAttributes)
{
var prop1 = prop.Descendants(ns + "add").First(p => p.Attribute("type").Value == "System.Web.Security.SqlMembershipProvider");
prop1.Attribute("type").Value = "sample.membershipprovider";
xDoc.Save(inputPathToConfigFile);
}

MVC 3 Application With ASP.Net Membership Provider Login Issue

I appear to have an unusual problem -
I've used the aspnet membership provider before without any issues but this just isn't working out for me.
I've added the schema to my database on sql server through the wizard. To configure the application for first use I run a script that fills the database with some sample accounts, roles, and other information.
After I run this script, I can login in within the application with the newly created usernames, use the features, etc. However after a while, or if I close the development server from the task bar, and then launch the application again and try to login - it won't validate the user. It fails the second IF statement to Validate the user and password below.
[HttpPost]
public ActionResult LogOn(LogOnModel model, string returnUrl)
{
if (ModelState.IsValid)
{
if (Membership.ValidateUser(model.UserName, model.Password))
{
FormsAuthentication.SetAuthCookie(model.UserName, model.RememberMe);
if (Url.IsLocalUrl(returnUrl) && returnUrl.Length > 1 && returnUrl.StartsWith("/")
&& !returnUrl.StartsWith("//") && !returnUrl.StartsWith("/\\"))
{
return Redirect(returnUrl);
}
else
{
return RedirectToAction("Index", "Home");
}
}
else
{
ModelState.AddModelError("", "The user name or password provided is incorrect.");
}
}
// If we got this far, something failed, redisplay form
return View(model);
}
If I check the database, the user is clearly there, however the incorrect password attempts field is still at 0, which might indicate that the application is not even recognising these as users. Also, If I check the website configuration (VS2010 -> Project -> ASP.NET Configuration) it shows that there are 0 existing users.
If I re-run the application, and run the setup script again, I can log in like before, however after again if I relaunch and try to login again I get the familiar incorrect password/username screen. Sometimes it happens on a different port number however sometimes the port numbers are the same and it still happens.
Here is the setup script:
protected void btnSetUp_Click(object sender, EventArgs e)
{
ModelContainer ctn = new ModelContainer();
Membership.ApplicationName = "MyApp";
Roles.ApplicationName = "MyApp";
if (!Roles.RoleExists("Administrator"))
Roles.CreateRole("Administrator");
if (!Roles.RoleExists("User"))
Roles.CreateRole("User");
// Delete all existing users.
//
foreach (MembershipUser user in Membership.GetAllUsers())
{
Membership.DeleteUser(user.UserName, true);
}
// Create the master admin account.
//
if (Membership.GetUser("admin#MyApp.com") == null)
{
MembershipUser adminUser = Membership.CreateUser("admin#MyApp.com", "admin123");
Roles.AddUserToRole("admin#MyApp.com", "Administrator");
}
CreateUser(ctn, "User#MyApp.com", "Joe Bloggs", "Employee", 1);
ctn.SaveChanges();
}
private void CreateUser(ModelContainer ctn, string emailAddress, string Name, string type, int baseShop)
{
// Create the User.
//
if (Membership.GetUser(emailAddress) == null)
{
MembershipUser adminUser = Membership.CreateUser(emailAddress, "admin123");
Roles.AddUserToRole(emailAddress, "User");
User u = new User
{
Name = Name,
Type = type,
BaseShop = baseShop,
Login = new Guid(adminUser.ProviderUserKey.ToString())
};
ctn.AddToUsers(u);
}
}
My Web.Config is more or less the default so I'm not sure if it's anything from that but there it is anyway:

Finding it very hard to be more descriptive of the issue but it's just puzzling. Is there a step I've missed in using the asp.net membership provider? Has anyone else come across this before?
Would be very grateful for any advice.

I think the problem is because you are using your own custom app in the setup code
Membership.ApplicationName = "MyApp";
Roles.ApplicationName = "MyApp";
but your web.config is using the default name
applicationName="/"

claimsResponse Return Null

hello i have a following code in asp.net. i have used DotNetOpenAuth.dll for openID. the code is under
protected void openidValidator_ServerValidate(object source, ServerValidateEventArgs args)
{
// This catches common typos that result in an invalid OpenID Identifier.
args.IsValid = Identifier.IsValid(args.Value);
}
protected void loginButton_Click(object sender, EventArgs e)
{
if (!this.Page.IsValid)
{
return; // don't login if custom validation failed.
}
try
{
using (OpenIdRelyingParty openid = this.createRelyingParty())
{
IAuthenticationRequest request = openid.CreateRequest(this.openIdBox.Text);
// This is where you would add any OpenID extensions you wanted
// to include in the authentication request.
ClaimsRequest objClmRequest = new ClaimsRequest();
objClmRequest.Email = DemandLevel.Request;
objClmRequest.Country = DemandLevel.Request;
request.AddExtension(objClmRequest);
// Send your visitor to their Provider for authentication.
request.RedirectToProvider();
}
}
catch (ProtocolException ex)
{
this.openidValidator.Text = ex.Message;
this.openidValidator.IsValid = false;
}
}
protected void Page_Load(object sender, EventArgs e)
{
this.openIdBox.Focus();
if (Request.QueryString["clearAssociations"] == "1")
{
Application.Remove("DotNetOpenAuth.OpenId.RelyingParty.OpenIdRelyingParty.ApplicationStore");
UriBuilder builder = new UriBuilder(Request.Url);
builder.Query = null;
Response.Redirect(builder.Uri.AbsoluteUri);
}
OpenIdRelyingParty openid = this.createRelyingParty();
var response = openid.GetResponse();
if (response != null)
{
switch (response.Status)
{
case AuthenticationStatus.Authenticated:
// This is where you would look for any OpenID extension responses included
// in the authentication assertion.
var claimsResponse = response.GetExtension<ClaimsResponse>();
State.ProfileFields = claimsResponse;
// Store off the "friendly" username to display -- NOT for username lookup
State.FriendlyLoginName = response.FriendlyIdentifierForDisplay;
// Use FormsAuthentication to tell ASP.NET that the user is now logged in,
// with the OpenID Claimed Identifier as their username.
FormsAuthentication.RedirectFromLoginPage(response.ClaimedIdentifier, false);
break;
case AuthenticationStatus.Canceled:
this.loginCanceledLabel.Visible = true;
break;
case AuthenticationStatus.Failed:
this.loginFailedLabel.Visible = true;
break;
// We don't need to handle SetupRequired because we're not setting
// IAuthenticationRequest.Mode to immediate mode.
////case AuthenticationStatus.SetupRequired:
//// break;
}
}
}
private OpenIdRelyingParty createRelyingParty()
{
OpenIdRelyingParty openid = new OpenIdRelyingParty();
int minsha, maxsha, minversion;
if (int.TryParse(Request.QueryString["minsha"], out minsha))
{
openid.SecuritySettings.MinimumHashBitLength = minsha;
}
if (int.TryParse(Request.QueryString["maxsha"], out maxsha))
{
openid.SecuritySettings.MaximumHashBitLength = maxsha;
}
if (int.TryParse(Request.QueryString["minversion"], out minversion))
{
switch (minversion)
{
case 1: openid.SecuritySettings.MinimumRequiredOpenIdVersion = ProtocolVersion.V10; break;
case 2: openid.SecuritySettings.MinimumRequiredOpenIdVersion = ProtocolVersion.V20; break;
default: throw new ArgumentOutOfRangeException("minversion");
}
}
return openid;
}
for above code I am always getting
var claimsResponse = response.GetExtension<ClaimsResponse>();
I am always getting claimsResponse == null. What is the reason why it happen. Is there any requirement which is required for openid like domain validation for RelyingParty?? please give me answer as soon as possible.

Also make sure that you have registered the information on your OpenID-account on the provider website, and allowed the information to be sent during the login process. I had the same problem using DotNetOpenAuth but it turned out the I hadn't entered the information on my myOpenID-account. Thought that the email address is always sent, but that is not the case even though the OpenID account is connected to a email address.
So on myOpenID make sure that you have a Registration Persona (Your Account->Registration Personas)

It looks like you're doing everything right. At this point it depends on the Provider you're using. Which one are you testing against? Some don't support Simple Registration (ClaimsRequest) at all. Others only support it for whitelisted RPs. Then others don't support it when your RP is at "localhost".
My advice: test against myopenid.com, as that seems to have good, consistent behavior and support for the Simple Registration extension. But your RP must always be prepared to receive null for ClaimsResponse, since you're never guaranteed the OP will give you anything.
Even if you get a non-null result, individual fields that you asked for (even if you marked them required) may be null or blank.

I dont know if you have solved the problem or not, but I found the solution after many hours of struggle. Actually you need to change your web.config file to claim email and fullname
here is web.config which works for me. I downloaded it from nerddinner project. Actually I copied everything except web.config and I was not getting the email field. So later on I found something else is wrong. I copied web.config from nerddinner project and everything was working.
here is the file, if you dont want to go to nerddinner project.
