its very urgent. reply asap..
I have class LoginController, the action login and it run okie:
[Code]....
And on control LoginUserControl that inherits Logon model, I get cookie then login action, but while i debugging, it's cookie is null though login is success.

But variable userName always null, Although I add cookie,

It's there a way to retreive cookie value in ASHX Handler ?
I set a cookie in a page, and i want to reteive it in my ashx. My cookie is always null.
I save my cookie like this
HttpCookie tokenCookie = new HttpCookie(cookieName);
tokenCookie.Values["siteGuid"] = authenticationInfo.SiteGuid.ToString();
HttpContext.Current.Response.Cookies.Add(tokenCookie);
I retreive my cookie like this
HttpCookie cookie = HttpContext.Current.Request.Cookies[cookieName];
return new Guid(cookie["siteGuid"]);
Ok sorry that was my fault. My handler was on a sub domaine.
Once the user has authenticated, I would like to base all of the information displayed to the user based on their username. Isn't that saved in the cookie?
For instance, I would like to pull all of their client information using a GridView and have the parameter set to the appropriate authentication information.
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 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 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 change the data by use cookie ,
this cookie is update by get param, i send the language and data suppose to updated to the correct culture.
my problame is that it happen only after i refresh by f5 key .
give me an example (or point me in the right direction) on how to store custom data in an ASP.NET Membership cookie? I need to add some custom properties like UserID and URLSlug to the cookie and be able to retrieve the information in the same way one would retrieve the Username.
Edit:
I used Code Poet's example and came up with the following.
When I set a breakpoint at Dim SerializedUser As String = SerializeUser(userData) the value of userData is right. It has all the properties I expect it to have.
The problem I'm now running into is that when I get to Dim userdata As String = authTicket.UserData (breakpoint), the value is "". I'd love to figure out what I'm doing wrong.
Here's the code.
Imports System
Imports System.Web
Imports System.Web.Security
Namespace Utilities.Authentication
Public NotInheritable Class CustomAuthentication
Private Sub New()
End Sub
Public Shared Function CreateAuthCookie(ByVal userName As String, ByVal userData As Domain.Models.UserSessionModel, ByVal persistent As Boolean) As HttpCookie
Dim issued As DateTime = DateTime.Now
''# formsAuth does not expose timeout!? have to hack around the
''# spoiled parts and keep moving..
Dim fooCookie As HttpCookie = FormsAuthentication.GetAuthCookie("foo", True)
Dim formsTimeout As Integer = Convert.ToInt32((fooCookie.Expires - DateTime.Now).TotalMinutes)
Dim expiration As DateTime = DateTime.Now.AddMinutes(formsTimeout)
Dim cookiePath As String = FormsAuthentication.FormsCookiePath
Dim SerializedUser As String = SerializeUser(userData)
Dim ticket = New FormsAuthenticationTicket(0, userName, issued, expiration, True, SerializedUser, cookiePath)
Return CreateAuthCookie(ticket, expiration, persistent)
End Function
Public Shared Function CreateAuthCookie(ByVal ticket As FormsAuthenticationTicket, ByVal expiration As DateTime, ByVal persistent As Boolean) As HttpCookie
Dim creamyFilling As String = FormsAuthentication.Encrypt(ticket)
Dim cookie = New HttpCookie(FormsAuthentication.FormsCookieName, creamyFilling) With { _
.Domain = FormsAuthentication.CookieDomain, _
.Path = FormsAuthentication.FormsCookiePath _
}
If persistent Then
cookie.Expires = expiration
End If
Return cookie
End Function
Public Shared Function RetrieveAuthUser() As Domain.Models.UserSessionModel
Dim cookieName As String = FormsAuthentication.FormsCookieName
Dim authCookie As HttpCookie = HttpContext.Current.Request.Cookies(cookieName)
Dim authTicket As FormsAuthenticationTicket = FormsAuthentication.Decrypt(authCookie.Value)
Dim userdata As String = authTicket.UserData
Dim usersessionmodel As New Domain.Models.UserSessionModel
usersessionmodel = DeserializeUser(userdata)
Return usersessionmodel
End Function
Private Shared Function SerializeUser(ByVal usersessionmodel As Domain.Models.UserSessionModel) As String
Dim bf As New Runtime.Serialization.Formatters.Binary.BinaryFormatter()
Dim mem As New IO.MemoryStream
bf.Serialize(mem, usersessionmodel)
Return Convert.ToBase64String(mem.ToArray())
End Function
Private Shared Function DeserializeUser(ByVal serializedusersessionmodel As String) As Domain.Models.UserSessionModel
Dim bf As New Runtime.Serialization.Formatters.Binary.BinaryFormatter()
Dim mem As New IO.MemoryStream(Convert.FromBase64String(serializedusersessionmodel))
Return DirectCast(bf.Deserialize(mem), Domain.Models.UserSessionModel)
End Function
End Class
End Namespace
Here's where I create all the magic. This method is in a "BaseController" class that inherits System.Web.Mvc.Controller
Protected Overrides Function CreateActionInvoker() As System.Web.Mvc.IActionInvoker
If User.Identity.IsAuthenticated Then ''# this if statement will eventually also check to make sure that the cookie actually exists.
Dim sessionuser As Domain.Models.UserSessionModel = New Domain.Models.UserSessionModel(OpenIdService.GetOpenId(HttpContext.User.Identity.Name).User)
HttpContext.Response.Cookies.Add(UrbanNow.Core.Utilities.Authentication.CustomAuthentication.CreateAuthCookie(HttpContext.User.Identity.Name, sessionuser, True))
End If
End Function
And here's how I try and retrieve the info.
Dim user As Domain.Models.UserSessionModel = CustomAuthentication.RetrieveAuthUser
I want to create a flash swf file that will store a token in Local Shared Object. What do I need to do to read that token and look it up in the database on the back end? Is this possible at all? here is a possible scenario:
User visits my web page. A token is generated on the server and stored in the database. Token is then saved in LSO. User leaves the site (maybe shuts down his computer) and comes back later. Token is read, located in the database and the user is recognized (lets say that token is a foreign key that links to other user data stored in the db). I researched this for quite a while and all I find is that flash can use LSO to store read data for flash movie. Does this mean that the data can not be accessed by the server?
using vs2008 writing a asp.net.vb application. I have a datasource on my asp page wich is connected to a gridview. I want to use a cookie value as an input parameter to a stored procedure whose ouput will populate the gridview.
View 7 RepliesI thought the .ASPXAUTH was for user authentication? Can anyone confirm if this cookie is indeed a security risk and/or contains session information? Is it even suppose to be used or is it some debug thing?

When calling Response.Cookie.Add(new HttpCookie("MyCookie", "objValue")); where does the cookie saved? on Client Machine or Server Machine?
EDIT:if saved in Client Machine, how can I read it from javascript then? I tried this kind of script.
function getCookie(c_name) {
var i, x, y, ARRcookies = document.cookie.split(";");
for (i = 0; i < ARRcookies.length; i++) {

I cannot get the cookie that I saved from code behind. When I look into the document.cookie object, it is just an empty string.

I am playing about just now trying to teach myself a little bit about the entity framework. I have a Gridview data bound to a Entity Date Source using the Entity Framework. If I select certain items in that list I then wish to redirect another page and populate another gridview with just the items selected (but with more detail, different includes/navigation properties)
This is probably the most simple thing but I have spent 2 hours banging my head on the wall trying to get this to work. Essentially I have a continue button which when clicked should identify all the UIDs (a column in the gridview) of the rows and allow me to subset to just these rows and pass them to another page to be rebound to another datagrid
i am still stumped with this operation: i am trying to retrieve a GridView selected row data..here is my code.. the commented part that gives me the selectedindex works just fine....but the one giving the selected row cell value does't work and there is no error.. The update operation is done successfully...weired. i need to assigned selected row cells values to variables ..do some calculations and then re-assign the result calculation to cell[9]..
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
string s = GridView1.SelectedRow.Cells[5].Text;
TextBox1.Text = s.ToString();
//string s2 = GridView1.SelectedIndex.ToString();
//TextBox1.Text = s2.ToString();
}
I have an accessdatasource with multiple columns, one column I use it to populate a dropdownlist. Can I use the data from other columns to insert into a table, insert being done in the aspx.vb page, without creating gridview etc.
Is it possible to make a detailsview one column visible= false and still be able to evaluate its contents?

I want to get data from the database and display it in gridview. The gridview should be editable. Meaning the user can add, edit and delete items/rows in the gridview. Everytime the user adds/updates/deletes an item, the gridview is also updated. However, these changes will only be saved to the database once the Save button is clicked.

View 1 RepliesI'm trying to make a dropdown list with data available based on the users login name. Heres what I have as my SQL Query in the SQLDataSource:
SELECT Client_Name, Client_ID FROM Client WHERE (Client_Name LIKE '%@Client_Name%')
So say if the login username is "User1" but the database client name is "User1 Steel" I want the dropdownlist to pull "User1 Steel" as the display and Client_ID as the value from the dropdown list.
