Remove Cookie From XMLHttpRequest Object?
Jun 23, 2010
I am making an ajax call with jquery like:
$.ajax({
url: "path/to/webservice.asmx"
beforeSend: function(xmlHTTPRequest) {
//modify headers here
//remove cookies
}
success: function() {
//do stuff
}
}
What I would like to do in the beforeSend function is take the incoming xmlHTTPRequest variable that is set and modify the headers to remove the cookie object that is in there, so in the call to my web service, it does not renew forms authentication in asp.net

I am busy building a shopping cart with cookies. I have datalist which I populate from the cookies with a delete button next to each cookie
[Code]....
Now the problem is that when I hit the delete / remove button to expire the cookie, what happens when repopulating the datalist is that it shows the original cookie with all it's values as well as a new entry where all the values are blank.

I am trying to use a custom ITempDataProvider provider to store TempData in a browser's cookie instead of session state. However, everything works fine except that I am unable to remove the cookie from the Response stream after reading it. The code exexutes fine but the cookie won't go away.

And in my controller:

I had an xml-serialization which worked fine, but as I have just knew it doesn't work in Opera browser. I think, it's security rules don't allow to write to cookies xml-content.What can I do? Can I use binary serialization or something else?

in my default.aspx page i have a dropdown List and a textbox with a submit button below that there are 2 listbox... and the dropdown list holds the names of the listbox
my logic here is to select an item from the dropdown list and put some text in the text box and submit the form which will add an item to the listbox selected.. but when i do this i get an error saying Object reference not set to an instance of an object. i tried to figure out the problem and found that when i remove the reference to the Site Master Page it works fine and when i undo and apply my reference back to the Site Master Page i get the same error.

For my site, I have a list of users and a list of events. I will be assigning users to each event. I have a table named EventUsers to hold this data:
EventUsers
EventID | UserID
1 | 123
1 | 456
2 | 789
On my page, I want to be able to add and remove users for a certain event. I could have a dropdown populated with users and an "Add" button next to it, then when I want to add a user, I pick one and click "Add". There would be a grid below it displaying all the users for the event, with "Delete" buttons for each one. The downside to this is that a database call is made for every Add and Delete.
Another option is to have two listboxes on the page - one on the left containing all users in the database, and another on the right which will contain users for the given event, and I can just add or remove from the list on the right. Then when I'm done, I click save, and it makes one database call. The only issue is that if I'm removing and adding, I'll have to delete every record in my EventUsers table for that event, and then add the changes. I've run into this before, and I've always gone with the dropdown method. What's the preferred method here?

I'm trying to create a string from the DateTime object which yields the format mm:dd:yyyy. Conventionally the DateTime object comes as mm:dd:yyyy hrs:min:sec AM/PM. Is there a way to quickly remove the hrs:min:sec AM/PM portion of the DateTime so that when I convert it toString() it will only result in mm:dd:yyyy?

How can I remove the html content and add new string to the Response object. If I use the Respose.Write method the page contains the string, but while taking the view source option from browser it will display some html tag like Doctype, head, body etc. My requirement is only the string should be displayed in the source.

I want to change the value in a cookie:
HttpCookie hc = new HttpCookie("HiddenColumns");
hc.Value = customView.HiddenFields;
hc.Expires = DateTime.Now.AddDays(365);
Response.SetCookie(hc);
Or this way:
Response.Cookies["HiddenColumns"].Value = customView.HiddenFields;;
Response.Cookies["HiddenColumns"].Expires = DateTime.Now.AddDays(365);
But when I retrieve the cookie value, it is still old, unless I do postback. I don't want to use Redirect.

I'm trying to use a webservice that first expects the clients to login, to retrieve a cookie to re-use.
This is done through a login(string user, string pass) method on the webservice.
Doing this through a browser works fine, we get a cookie, and we can see the cookie via Fiddler or whatvever proxysniff thingy.
Time to do the same in ASP.Net, so we use the WSDL and generate a nice proxy class, and it works fine to call the login() method, but Never Ever does a cookie get set !
I already used the "cookiejar" technique - which means i create an instance of a CookieContainer and assign it to the proxyclass like this;
var cookies = new CookieContainer(3);

I want to use Ajax XMLHttpRequest and get data from a database table and show it on the screen. I followed the link "Guide to Using AJAX and XMLHttpRequest from WebPasties" http://www.webpasties.com/xmlHttpRequest/index.html but there the code some part is written in PHP. I want entire steps and code in asp.net etc. Can you please give me a link where exactly I create XMLHttpRequest and get data from database. To achieve the above requirement do I need to AjaxFy my asp.net webapplication by adding configuration in the web.config file.

On "submitForms" click the fucntion "submitTest" is invoked. From jQuery documantation "submitHandler" would be called if form is VALID. So, the validation works and "submitHandler" is NOT invoked if form is INVALID. BUT, the XmlHttpRequest is sent anyway, though "submitHandler" isn't invoked.
<% using (Ajax.BeginForm("FormPost", "Customer", null, new AjaxOptions() { HttpMethod = "POST" }, new { @class = "form-container" })) { %> <%: Html.TextAreaFor(m => m.Name, new { width = 440, height = 100 })%> <input type="button" value="submitForms" /> <% }%><script type="text/javascript">function submitTest(){var forms = $(".form-container");forms.each(function (index, form) { $(form).validate({ submitHandler: function (form) { $.ajax( { .... }); } });});forms.each(function (index, form) { $(form).submit();});}</script>

I have many AJAX forms on the page and on button click I need to submit them all. Regular **forms.each(function (index, form) { $(form).submit();} won't work for me because in this way ONLY the last form will be submitted eventually. Therefore, I need submit them via $.ajax(...). But I want to enable submit ONLY and ONLY if form is VALID On "submitForms" click the fucntion "submitTest" is invoked.

I have what should be a relatively simple task that's frankly got me stumped. I've researched it until my brain is fried, and now I'm puntingHere's the scenario:I have an ASPX page (Q2.aspx) that is decorated with the WebService,WebServiceBinding, and ScriptService attributes. That page contains a method, GetAllContacts, that is decorated with the WebMethodattribute and returns a string containing JSON data. (For what it's worth, the pageitself contains no other controls or functionality.)I have an HTML page that contains JavaScript which uses the XmlHttpRequestobject to invoke the GetAllContacts WebMethod on the ASPX page and transformthe JSON data into an HTML table. I have verified that my Web.Config file contains the appropriate protocol handlersfor HttpGet and HttpPut in the WebServices section under System.Web.webServices.
I have verified that my Web.Config file contains the ScriptModule entry under theSystem.webServer.modules section, and that it matches the appropriate documentation.
However, when I view the HTML page in a browser, the following occur:The web request goes through, but the results are for the unprocessed HTML from the ASPX page.The GetAllContacts method is never invoked, as evidenced by setting a breakpoint in its code.The code to invoke the Web service, however, is invoked, and the JavaScript callbackfunction that is invoked upon request completion is properly invoked.
It appears that the JavaScript code is largely set up correctly, but for some reason that is completely escaping me at this point, the HTML page will simply not execute the WebMethod on the ASPX page, and simply returns the page as though it were a plain HTML GET request. Clearly, an HTML document can't be evaluated by JavaScript's eval function, which brings me to my problem. (Also note that the JSON data appears nowhere in the HTML that's returned.)I am, frankly, baffled. I've looked at dozens of Microsoft articles, StackOverflow posts, CodeProject articles, and who knows what else. My code looks like it's okay. But I know better. I'm missing something simple, stupid, and obvious. I just need someone to point it out to me.Below you'll find the ASPX page code and the HTML code, in the hope that they'll shed some light.ASPX Code
<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Q2.aspx.cs" Inherits="Satuit.Q2" enablesessionstate="False" %>

I'm building a web app for my company that will run a query every few seconds against SQL Server, and the data that it returns is which database is restoring and how much % complete it is. I have the query already set up and it works fine.
What I want to do is on my Web Form, have a "div" element that will contain the % complete of a database restore, and have it update every few seconds using the JavaScript timer object:
setInterval(function, interval)
I figure I would need to use XMLHttpRequest to send the request to the web server which will run the SQL query. Am I on the right track? How would I even start to do this?
My SQL query is below:
Use master
Select der.session_id, der.command, der.status, der.percent_complete, *
From sys.dm_exec_requests as der
Where percent_complete > 0

I am a bit baffled here; using IE7, ASP.NET 2.0 and Cassini (the VS built-in web server; although the same thing seems to be true for "real" applications deployed in IIS) I am looking for the session-id-cookie. My test page shows a session id (by printing out Session.SessionId) and Response.Cookies.Keys contains ASP.NET_SessionId. So far so good.
But I cannot find the cookie in IEs cookie-store! Nor does "remove all cookies" reset the session (as it does in FF)... So where - I am tempted to write that four letter word - does IE store that bloody cookie? Or am I missing something? By the way there is no hidden field with a session id either, as far as I can see. If I check in FF there is a cookie called ASP.NET_SessionId as I would expect. And as mentioned above deleting that cookie does start a new session; as I would expect.

I need to retrieve a table from MS SQL 2005 database using AJAX.
But I only know a traditional way using ADO.NET.
I have read some books and it said we need to use XmlHttpRequest to retrieve data from database but I don't really understand the concept.

I am trying to send JSON from my mozilla addon to my asp.net page.
var myJSONObject = {"userName": una,"password": pass};
request = new XMLHttpRequest();
request.open("GET","http://www.google.com?jo=" + myJSONObject,true, null, null);
on my .net page I have tried several ways of doing it but not able to find the best way to serialize and deserialize the code. All I need is to send the json data back n forth and parse it on C# n javascript.
I have tried DataContractJsonSerializer, JavaScriptSerilizer among many other things. But not able to make any of it work. With the JavaScriptSerilizer, It does deserilize it if it takes an argument from the browser for e.g. If I open up the browser and paste something like [URL]} it does deserilize and return me individual values, but it does work when I do an XMLHTTPRequest (as above) from my mozilla addon.

I need to upload and save an image onto the server. I am using an XMLHttpRequest POST to send the image to the server and calling a class named imageSave.aspx.I am finding difficulty in "catching" the image from server side (imageSave.aspx) and saving it onto the server.
Does anyone please have some tips as to how this is done or maybe link to a good article or something?
Code used to perform the http POST....
xhr = new XMLHttpRequest();
// Update progress bar etc [code].....
