System.ArgumentException While Setting HttpContext.Current.User
Sep 9, 2010
I am trying to configure one http module(a vb module) on MOSS site. In this module I have entry like below:
Dim roles As String() = Nothing
Dim webIdentity As New GenericIdentity(OracleUser, "Form")
Dim principal As New GenericPrincipal(webIdentity, roles)
HttpContext.Current.User = principal
System.Web.Security.FormsAuthentication.RedirectFromLoginPage(HttpContext.Current.User.Identity.Name.ToString, False)
Due to this I am getting 500 internal server and exception on browser is: Exception of type 'System.ArgumentException' was thrown.
Parameter name: encodedValue
If I comment "HttpContext.Current.User" related two lines then it redirect to form login.
I created an AutocompleteExtender web service. I am getting a Object reference not set error in the peice of the code where I am referring to System.Web.HttpContext.Current.Session. Does anyone know why this is. And I am checking to see if it is != null before I reference it. But it crashes. Is there another way to pass another parameter to the web service?
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Try loginRep = BusinessLogic.SR.GetUserName("99999") System.Web.HttpContext.Current.Items.Clear() System.Web.HttpContext.Current.Items.Add("RepId",loginRep)
I don't any errors and when in the run in the immediate window:
? System.Web.HttpContext.Current.items("RepId") in the immediate window on THAT page I get the OBJECT.
Then I have a hyperlink with navigateurl to the next page "~/ActCnt.aspx"
On that page, ActCnt.aspx, when in the code I have:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.LoadIf Not Page.IsPostBack Then Dim loginRep As BusinessLogic.SalesRep = System.Web.HttpContext.Current.Items("RepId")
In the immediate window ? System.Web.HttpContext.Current.Items("RepId") returns a String that is equal to "RepId".
Even if I change it to not be an object, but a string I only get the Name "RepId" of the keypair. I have NEVER gotten the actual value.
am writing a web service in vb.net/asp.net 2, that needs user's name. It works fine when the url request is "www.mysite.com" but if any one has logged-in using "mysite.com" without a "www" and goes to the page that calls my web service, The HttpContext.Current.User.Identity.Name gives null. How can I resolve this problem?
I have a security manager in my application that works for both windows and web, the process is simple, just takes the user and pwd and authenticates them against a database then sets the Thread.CurrentPrincipal with a custom principal. For windows applications this works fine, but I have problems with web applications.
After the process of authentication, when I'm trying to set the Current.User to the custom principal from Thread.CurrentPrincipal this last one contains a GenericPrincipal. Am I doing something wrong? This is my code:
i work with visual studio 2005 and asp net 2.0. i have a method method as this :
[Code]....
this problem is follow if i run the web method and don't enter a string and a int a receive this message : System.ArgumentException: Cannot convert to System.Int32. ok when i arrive in the method i can check if lists is empty but how i can do if int is NULL because i don't want to returns a error if people run my web method and don't enter the parameters.
I create two pages, the first one is the login page with user name and password textboxes - (not asp login control) , when clicking login button I check the login authentication, if it is true redirect to default page. in the default page if !IsCallBack then i check httpcontext.current.user.identity.isauthenticated
if it is false i redirect the user to the login page. but my problem is that the httpcontext.current.user.identity.isauthenticated is always false.
I was/am struggling with security for my first MVC applicaiton. It worked out great for me, but not for my users. I wanted to use Windows Authentication (and I seem to have that working). But when I was still trying to implement it, I was on one of our users computers where they were logged in. I navigated to the main Index page and used the supplied MVC login link and *MY* credentials. So now every time that user navigates to that page, it logs her in as me. We are using IE8, I have deleted all the cookies, passwords, forms information I can fine through Tools|Internet Options|Tool|Content|AutoComplete.
We have an SharePoint site no login (anonymous) with a search module using AJAX. Now the users complains that the module isn't working. When I check the code (not developed by me), I find that the code only runs if "HttpContext.Current.User.Identity.IsAuthenticated=true". Could that ever return true on an anonymous site?
I have use Nhibernate in my MVC Project by me known, Nhibernate have cache on Session and Object. now, I want use HttpContext.Current.Cache (system.web) for cache data something in project. my code same that have problem, haven't it. and that's right or wrong.
I use Membership.ValidateUser to check user credentials, but when I do so, I get the following ArgumentException: "The serviceUri configuration setting was not found." I just can't understand what is the problem here.
I get this Microsoft .NET Framework start up error. when i try to run a window project.
i am working on visual studio2005 (.NET FRAMEWORK2.0).
i am working on win 7 machine & i am not able to edit machine.config file.coz it is read only type.
below is the error ....

I have a static class with serveral static methods. In these methods, I'm trying to access the current thread's context using HttpContext.Current. For example:
var userName = HttpContext.Current.User.Identity.Name;
However, when I do that, I receive a NullReferenceException, the infamous "Object reference not set to an instance of an object."
Is there a good way to test and debug these errors. I constantly get them emailed to me from my production site but I can not duplicate them. Below is the entire error.

In the codes below, I got an error on the 2nd line. The "Connection" string is defined in Web.Config.
What does the Exception Details mean? How to solve the error?
Dim strConn As String = ConfigurationManager.ConnectionStrings("Connection").ConnectionString Dim conn As New SqlConnection("strConn") Dim queryString As String = "SELECT CustomerID, CompanyName FROM dbo.Customers" Dim adapter As SqlDataAdapter = New SqlDataAdapter(queryString, conn) Dim customers As DataSet = New DataSet adapter.Fill(customers, "Customers")

i'm using an example in which i can fake the session.It's for use in a unittest of a mvc controller.In the test i create a controller and then i do this:
FakeHttpContext httpctx = new FakeHttpContext(null,null,null,null,mSessionItems ); ControllerContext ctx2 = new ControllerContext(httpctx,new RouteData(), target);
here mSessionItems is my session and target is my instance of a controller,and indeed, when i'm in a controller reading this.ControllerContext.HttpContext.Session, i have a session, great!but.... i also read the session outside the controller, and there i use HttpContext.Current.Session, and that is null (or actualy, the HttpContext.Current is null).
I am trying to connect forex trade server from my asp.net application. I am using MT4 Api for connecting. Its installed successfully and added to .net code library. But when i trying to create object of MetaTrader Class i got exception
The current configuration system does not support user-scoped settings.
There is no compile time error in code. I am getting run time exception.
There are the urls where i got some hope for solution but could not able to implement.
As per title. I want to be able to save some data in a cache object but this object must be available to all users/sessions and can expire.What is the best method to achieve this in a asp.net web app?
