The question is how can i read back the contents of the list, stored in the Session?
I mean something like...Build = Session("MyData")
I'm using Session variables inside a web service to maintain state between successive method calls by an external application called QBWC. I set this up by decorating my web service methods with this attribute:
[WebMethod(EnableSession = true)]
I'm using the Session variable to store an instance of a custom object called QueueManager. The QueueManager has a property called ChangeQueue which looks like this:
[Serializable]
public class QueueManager
{

I have a website written in C# that was running fine on one server. We moved it to another server and have a couple issues. I am mainly a VB.NET coder but can do a few things in C#. This is not a project - it is a website and can open it in VS2008 no problem. This is an admin site for the whole website where the user can add customer comments, etc. When logging in, it works fine. I can go to one of the admin pages after logging in and works. If I go to two other different pages, I get this error:
Object reference not set to an instance of an object.
[Code]....
It turns out this is in the main.master page and it is used by the other pages that load fine. The ApplicationTitle variable is set right in the web.config file and like I said, it shows on the other pages.
My question is why would this code work fine for some pages and not two others? All of these admin pages are under a folder called Admin and the web.config file is in the root folder of the website. Its almost like these two pages cannot see the web.config file in the root folder? Why would that be if thats the case?
which place(exact folder) the session & session id will be stored?
View 8 RepliesIs it possible to use mixed cookieless sessions with cookie sessions? I've an application that captured user details and then redirect for payment to an ssl page. I was wondering if this is possible? [URL] redirects to [URL] Note: the session Id in the latter url. So in essence, we use the standard cookie session for the majority of the application but when we transfer to an ssl page we pass the SessionId to the https url to pick up the session. I've tried this locally but it starts a new session.
View 1 RepliesIn the VS2005 environment, when I test my session to make sure the page redirects to the main page (itself) if the session is null, it works. There is no error.
The function I use for this is:
[code]....
However, when it is in the production environment in IIS 6.0, when the session has timed out, and I then do a postback by doing some slider control, I see the page reload but immediately thereafter, it throws a Server Error exception of : Object reference not set to an instance of object.
Looking at the stack trace, the event occured:
AJAXEnabledWebApplication1._Default.Slider1_TextChanged(Object sender, EventArgs e)
however, why is it that the Slider1_TextChanged event fired even even after during page_load, the page was told to do a response.direct ?? shouldn't the entire page have gone through a full-page refresh life cycle ? why did it continue on to attempt to raise the Slider1_TextChanged event?
I am getting object refernce error at line:if (Session["Tax"].ToString() == "9")
protected void Page_Load(object sender, EventArgs e)

}
else
{
lblTax.Text = "0";
}
}
Is anything wrong I have done?
I am confused about how to reference objects in session, how to update, and copy.
if I create
MyObject obj = new Object ();
then
Session["object"] = obj;
MyObject temp = (MyObject)Session["object"];
If i change something on temp, will the object in session be updated? do i need to follow changes with Session["object"] = temp?
I want to be able to persist data across a session but do this outside of the built-in session state object. Why is a long story that I will not go into here. I just need to know where I can put data other than in the session object that will persist across the specific session.
View 3 RepliesI'm looking for a simple solution to disable the IE functionality of the backspace key behaving like a back button. I have textboxes that are dynamically set to read only depending on certain criteria. If the user hits the backspace key when focus is on a read only textbox it navigates back a page. I would like to disable this functionality.

View 2 RepliesCurrently in an .aspx file, I am storing a value (filename that was created in that session) in an hidden text box. When the user clicks on the "Print" labeled Hyperlink control, it opens the file that was stored in the hidden text box control. But when the user goes to different screen (in the same session), I loose the filename value that is stored in the hidden text box control. So I would like to store the filename variable in a session variable. So that if the user leaves this .aspx file and comes back to this .aspx file I can load the value into the hidden text box from the session variable.

How can I read a url for example like this:
www.mywebsite.com/dan
www.mywebsite.com/mike
I want to be able to read that into a session("MemberName") - EX: Session(MemberName") = dan
Here is the problems:
I dont know every member name that might come to the website.
How can I prevent it from reading a url like this into the session:
www.mywebsite.com/default.aspx or any other pages... Which might make the session look like Session("MemberName") = default.aspx

This is part of the code where error is coming from................
I am using c# and jQuery.
I have below code where I am setting the Session Variable using C# code.
if (!string.IsNullOrEmpty(results))
{
string[] array = results.Split(',');
string firstName = array[0];
string lastName = array[1];
string activeCardNo = array[2];
string memberShipTier = array[3];
string accessToken = array[4];
Session["skyFirstName"] = firstName.ToString();
Session["skyLastName"] = lastName.ToString();
Session["skyActiveCardNo"] = activeCardNo.ToString();
Session["skyMemberShipTier"] = memberShipTier.ToString();
Session["boolSignOn"] = "true";
Response.Redirect(fromPage);
Response.End();
}
Now I want to read these values (Session["skyFirstName"]) using jQuery so that I can set in my elements.
