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)
{
if (Session["Tax"].ToString() == "9")
{
lblTax.Text = Session["Tax"].ToString();
}
else
{
lblTax.Text = "0";
}
}
Is anything wrong I have done?

View 2 RepliesIn my web application, I use an exit button which runs session.abandon to close the session and then close the browser. It does not work with multi-tabs in IE. If I open my application in two tabs, I click on the exit button in one tab which abandons the session and close the tab. But the application in another tab can still work. Is there any way to close the session for this application in all the tabs?

Now in login page after firsttime login i set some session data... like
protected void Login_LoggedIn(object sender, EventArgs e)
{
//.....
Session["EMPLOYEELOGGEDIN"] = "Y";
//.....
}
Now say i close the browser... and next time when i open the site it takes me directly to the default page [Login_LoggedIn is not called accordingly]... because i'm already logged in for 30 mins acc. to configuration. but as my session id gets changed i can't access Session["EMPLOYEELOGGEDIN"] from any page in this time. It always returns null. But how do i get back the previous session for that person?

View 3 RepliesI have a System.Data.Linq.DataContext object and need to know the proper way of closing it out before it goes out of scope in order to prevent the following error when making a bunch of database changes:
Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.
Can I just call obj.Dispose() or do I need to call obj.Connection.Dispose() or obj.Connection.Close()?
I guess what I want to know is will calling obj.Dispose() end up executing the functionality in obj.Connection.Dispose() and obj.Connection.Close(). The MSDN documentation that I found on these functions does not have this information (at least I didn't see it - I could have mistakenly overlooked it).

View 4 RepliesI want to show a popup about browser compatibility to the users visiting my website. I have used the popup in about 5 pages and it would be annoying for the users to see the same popup for more than once when they visit my website. So I am thinking to use a session and kill it when the user closes the poup. IT should not be shown until the browser is restarted.

View 3 RepliesI 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;

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 have this problem when trying to read a session in another asp.net page.
Object reference not set to an instance of an object.
If Session("cne").Equals("") Then Response.Redirect("Default.aspx")End If
I'm setting the session in the Default page with this code :
Session("cne") = cne.Text
what is this error and how to solve
a different object with the same identifier value was already associated with the session:
I am using Session state in my ASP.NET application. The development is done using InProc session state as the option, but now the application is deployed on a Web Farm(Cluster) environment. As a result, InProc session state is not working.
I have changed the session state mode to SQL server so the session state will work in Web Farm environment. But now i am getting a different error because of some of the objects which i have already used with Session.
Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. The same restriction applies if similar serialization is done by the custom session state store in 'Custom' mode.
I understand that every object that is stored in Session needs to be serialized. But there are some objects which are not serializble in DOTNET.
Unfortunately i am using one of them, SiteMapNode. I am storing this object in session to re-create the breadcrumb based on the navigation the user has performed. I have to do this because there are mulitiple paths leading to single page in my application.
I have tried to do serialization of this object using XML serializer object, but its throwing an exception:
"System.Web.SiteMapNode cannot be serialized because it does not have a parameterless constructor."
I can't change the code of storing the SiteMapNode in session as it is very complex and written by someone else. I have to store this object in session or some other state form so that i can continue using the same code.
creating session object to use across my web application.
I'm working on an application that requires a login control upon which we would need to set around 10 different session variables (related to the user). These values are required/ used many times across the web application so it would be really handy to create a class/ object which can be accessed in all pages with doing multiple lookups into the user table on DB. Also, I would like to avoid any conflicts with multiple developers using same session variable names and thereby causing issues down the road.
I know this is not a new kind of request and must have been created and used by many of the developers.
In my app. I redirect user from one domain to another and I need to preserve the session object while redirecting between domains.
I need to be able to read session key/value that is created under different domain, for example -
While in domain A.com:
create session variable - session("myASPString") = "Test string"
redirecting to domain B.com
While in domain B.com:
dim k as string = session("myASPString")
right now k = Nothing...
How can I preserve the session object between different domains ?
