View 1 RepliesNopContext.Current.User Is Always Null?
Nov 3, 2010I've been developing an application based on nopCommerce 1.60. I'm developing on Windows 7 Pro 64bit.
I'm deploying the application to Windows server 2003 R2 (32bit) for staging and this works fine. It works perfectly and exactly like when I run it on the Visual Studio dev server.
I've just deployed the code to the live server for testing in that environment and I've got a real show stopper. NopContext.Current.User is always null!
The live server is Windows 2003 R2 64bit, and this is the only difference I can see. I've been through every page of the site settings in IIS on both servers and made sure every setting is the same, I've also done the same for the Application Pool.
MVC :: HttpContext.Current.Session Item Is Null?
Jan 17, 2011i'm storing in HttpContext.Current.Session current user, SiteUser is single-tone class that presents current active siteuser, and when he logged i'm creating new SiteUser() in controller and in constructor adding him to the session:
[Code]....
then, with every request to the server services i'm check is user available in session:
[Code]....
otherwise i'm generate non-auth-user exception and redirect him to the logon page. but sometimes HttpContext.Current.Session[sessionKey] is null, but HttpContext.Current.Session doesn't null and FormsAuthenticationTicket is available and Expired property is also false. can somebody help me, why HttpContext.Current.Session[sessionKey] can be null?UPDi have downloaded symbol tables of source .NET Framework and set breakpoints at SessionStateItemCollection on changing collection items. and i resolved some mistakes:1) all collection items are null — "culture" is setting up after2) it happens at the session end eventi can't understand how it can be, because at web.config session timeout is set 20
Web Forms :: HttpContext.Current NULL When Using .NET ReportViewer And An ObjectDataSource
Mar 10, 2010I have an ASP.NET Web Forms app using Entity Framework in the data layer. I've recently changed the app over to use one Object Context per request as per this post. It works great for the entire application except for any page which uses a ReportViewer to display something.
I've noticed that it fails when trying to get an instance of the [Code].... from the [Code].... collection because [Code]....
is null.
Microsoft.ReportViewer.WebForms.dll and Microsoft.ReportViewer.Common.dll can also be seen in the call stack each time it fails. The reports each use one or more ObjectDataSources to retreive data.
Based on this I'm assuming that the ReportViewer is somehow to blame, but i have no idea why. I would need some way to dispose the ObjectContext after it had been used by the report at the very least.
Why HttpContext.Current.Session Is Null In Global.asax
Nov 15, 2010I'm using VS2010 and created a simple asp. web forms application, using Development Server to test it. I try to store user data - queried from sql server - in the session, since I don't want to access database in every request. I'm using the 'Application_AuthenticateRequest' and the 'Session_Start' methods.
First round:
AuthenticateRequest called. The following code ran:
[Code]....
The _current variable is a private static field published through a static property. In the first round the Session is null, and I think it's ok because the Session_Start not called yet. The Session_Start looks like this:
protected void Session_Start(object sender, EventArgs e)
{
Session["EMPLOYEE_DATA"] = EmployeeFactory.Current;
}
In the next round the Session_Start is not called of course but in the AuthenticateRequest I can't access to the session. The HttpContext.Current.Session is null and the this.Session reference throw a HttpException says the "Session state is not available in this context".
However I can access the Session from any of the page_load events but it's a bad practice I think that I put authentication every page_load.
ASMX :: WCF Service Find Current Url?
Oct 7, 2010 I have a WCF Service that loads a file located on a local web server. How can I load that file based off an Uri? So I don't have to hard code in the address? So instead of doing a XmlDocument.Load(http://mywebaddress/ConfigFile/config.xml); I could put in or find the current URL of webservice then add the parameter. Sort of like this:
XmlDocument.Load("~/ConfigFile/config.xml"); That way if I'm publishing or Debugging it's all one file in the same exact location.
State Management :: Users Getting Logged Out Because HttpContext.Current Is Null?
Aug 19, 2010We've got a fairly large, complex web application that uses Forms Authentication to authenticate users. Throughout the application we store and retrieve information about users in the Session object, and in some cases in cookies. In a couple places we check for the existence of the context, and if it's null we send the user back to the login page to re-establish the session. Just a quick run-down of this web app: C#, .NET 3.5, IIS 6, ASP.NET State Service to manage sessionAs for the session timer, we use our own home-grown timer, which is basically a client-side timer, which is backed up by a check to the SQL database to see when their last activity was. This seems to work well for us. It's not perfect, but it allows us to notify the user before the session times out, and allows us to be certain we're not logging a user out before their 60 minutes of inactivity is up.What's happening is that certain users are being logged out after just a few minutes. We've eliminated the timer as a cause and believe what's happening is the HttpContext.Current is null, so the user is logged out. We do not know why the HttpContext.Current is null, and I understand there are many reasons that may occur. What I'm trying to figure out is, is there any way to re-establish the context once it is null? If not, is there anything I can do at this point other than have the user login again? We're also trying to figure out a better way of managing user information (preferences, roles, flags, history, etc), but everything needs context to use, right? Cookies, sessions, cache, etc. all require a response or request, correct? hope this makes sense, because I really need help with this. I've searched the forums here, and found many posts about HttpContext.Current going null, but not a lot of solutions for this...

WCF / ASMX :: Webservice Namespace - Input Is Null?
Nov 13, 2010I have a ASP.NET webservice which is called by a Java client. The client sends a SOAP message as input but the problem is that it never reaches my webservice method. I always get null as input. I used TraceListener and saw this warning which may cause the problem:
The element was not expected in this context: <ListenerInput>..</ListenerInput>. Expected elements: http://client.ns.url/:ListenerInput.
This is what the client sends:

WCF / ASMX :: Accessing A Published Web Service Gives Null Ref Exception?
Sep 2, 2010I have an Asp.net web service that I created using Visual Studio 2005. I can acess the web service in my test environment, call methods and return data as expected. If this web service is published to the outside world (Outside of the company firewall), it will return a null why this might be happening? The same code is being used,against the same database. The only difference is that the published website is giving back the null reference exception. If I type in the URL for the web service "https://secure.theSiteGeist.com/wsIndigo.asmx" a list of methods for the web service is displayed in my browser. Yet if I try and call any methods on the web service I get back the null reference exception. Note that the URL I posted above is not the real name of my web service, but is just used for reference sake.

WCF / ASMX :: Access Denied And Null Returned While Accessing Web Services From Remote Server?
Sep 2, 2010 writing a web Service and one of its web method, I want it to download a png file in form
of buffer from remote server. And My consume application will write that buffer retured by Web service in to file on User's Computer.
However, I am able to do this using Local Web Service but when I published that service on my web server, I always get null retuned
And even in one of my test code while copying file from that server , I always get Access Denied.
Following things I have done for above issue.
1] I even tried making the Anonymous user for the web service the system administrator (with the correct password), to no avail.
2] I also tried sharing out the folder I'm pulling files from to allow access from Everyone.
[Previously same service was working fine on another remote server with IIS 7.0, we checked server IIS Settings but in vain.]
if you know where we are mistaken guide me to resolve this issue as its very urgent.

HttpHandlers / Modules :: Session Null In Module Event (PreRequestHandlerExecute) For .asmx Web Service ?
Jun 18, 2010I have a module that subscribes to PreRequestHandlerExecute event, which uses the Session object.

View 3 RepliesRenderAction Not Finding Action Method In Current Controller In Current Area?
Mar 15, 2010I'm creating an ASP.NET MVC 2 (RTM) project that uses areas. The Index action of the Home controller of one area needs to use RenderAction to generate a sub-section of the page. The action called is also defined in the same Home controller. So the call should just be:
<% Html.RenderAction("List") %>
However, I get an exception:A public action method 'List' was not found on controller 'RareBridge.Web.Areas.Events.Controllers.HomeController'.
Note that I'm not in the "Events" area! I'm in a completely different area. If I remove the "Events" home controller, then the exception still occurs but names a different controller (still not the one I want it to call).
I've also tried providing the controller name and area to the RenderAction method, but the same exception occurs. What is going on here?
BTW: I am using Autofac as my IoC container
Web Forms :: Find Current URL Of Page During Code Behind Submission (NOT Current Web App URL)
Aug 18, 2010I am looking for a way to figure out the current URL that the page is currently on (NOT what the asp.net page currently is, but where the CODE is at). ie. My web app is located at: [URL] my code is: String page = [URL]
String response = GetResponse(page); //basically the above code goes to the website [URL] and parses the HTML within it and brings it back and populates the variable string "response". But, sometimes the [URL] throws me a curve ball and redirects me to: [URL] I want to be able to use a try/catch to be able to "catch" the error of a different page: ie validateUser.aspx. So, I need to do to this: try
{
String page = [URL];
String response = GetResponse(page);
}
catch
{
//code to check the behind URL to see if [URL] is the URL OR IF [URL] is the current URL
}
understand I know how to find the URL of the current page the web app is on. I need to find the current page that threw the exception during the execution of the code behind.
