I want to access the user session from a web method. But when I check for the session object, its nothing! How can I access the current user's session from the webmethod?
My code:
<System.Web.Script.Services.ScriptService()> _
<WebService(Namespace:="http://tempuri.org/")> _
<WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)> _
<Global.Microsoft.VisualBasic.CompilerServices.DesignerGenerated()> _.......
I am looking at a design pattern which has come up in quite a few of my firm's projects.It has historically functioned correctly, however I have heard some other developers argue that there is a possibility of session corruption using this pattern. I'm looking for insight from other .NET developers here on Stack Overflow. Basically, there's a class -- usually either static or a Singleton pattern, depending largely on the developer who wrote it -- stored in App_Code.This class encapsulates access to the current session via properties.All of these properties take the form of:
[code]...
However,because this is just a static entry to HttpContext.Current.Session,it seems like it should be safe, as it is not fundamentally any different than the Page class encapsulating this in the Session property.As I said,no other site on which my company has worked that used this pattern saw it ever have any issues -- and that includes some pretty large and highly active userbases.But I want to just get a fresh perspective.
Are there potential multi-user issues, race conditions, or other failings/flaws which specifically could cause session corruption in the above pattern?
when we accept user details in a login page and i want to use login details throughout the website.....can we do like this

I am to access a method on my master page. I have an error label which I want to update based on error messages I get from my site.
public string ErrorText
{
get { return this.infoLabel.Text; }
set { this.infoLabel.Text = value; }
}
How can I access this from my user control or classes that I set up?
Let suppose, I am building an asp.net website which has login scenario in it. I want to provide a certain functionality to the website that if the user is already login on computer 1 and now try to login on computer 2, so he will be allowed to remain login on computer 2, while automatically logout him from computer 1. I also know that http is a stateless medium, so whenever user interact with computer 1 and try to interact with the page, it will get noticed at that time.

I been using Session.clear() and I noticed in firecookie that the session still exists. So I started to google around and found there are 4 ways to remove a session
Session.Remove(strSessionName); Remove an Item from Session State Collection
Session.RemoveAll() Remove all items from session collection
Session.Clear() Remove all items from session collection Note: There is no difference between Clear and RemoveAll. RemoveAll() calls Clear(), internally.
Session.Abandon() Cancels the Current Session
Now clear and remove seem to do the same thing but which one should you be using like why use remove() over abandon over clear.
Like if you use session.Abandon it kills the current session. Where clear() removes the values.
Why would you only want to keep the session around with no values in it? Why not just kill it completely?

I have the following two pages. One is a search page that have a few listbox/textbox/and dropdownlist. The other will be the result page that take from session those 3 data and using an if/else statement to sort out some detail. After that it will form an access/sql selectcommand to search the database base on that 3 criteria. But for some weird reason only the first part of my if and else statement work. Can anyone check and help me out why the rest of the if/else doesn't work. Or point me to another direction?

I'm currently developing a website using .net MVC 3 and I'm on the authentication layer...Here is the scenario: user is logged with the "remember me" option checked : a user Session is created on the server as well as the authentication cookie on the client side.The Session timeout is set to 20 minutes.After 25 minutes of inactivity the user goes back onto the website and Session, now expired, does not exist anymore but the authentication cookie still exists
View 1 RepliesI have written a SP which maintains users log in and log out history,it works fine when any user logs in or clicks on log out, problem is that as per need its not to allowed to keep the screen idle for 1 minute or more then in the log out column Null value is passed.
SP
Create proc usp_trackuserlogindetails
@username varchar(50) = null,
@command int = 0
as
BEGIN
if(@command = 0)
begin
insert into userlog (USERNAME,LOGIN,LOGOUT) values (@username,Getdate(),Null)
[Code] ....
Here when user manually clicks the log out button then 1(table above) is the output.
When user leaves the screen idle then after 1 minute the page goes to the Login.aspx page if the user tries to do something on the current page,here 2(table above) is the output can i store some hard core value instead of Null like Session expire or the exact session expires time.
Is it possible to perform user management (store user info, login , logout etc) without using session or cookie?

View 1 RepliesI am storing the returned sql resultant rows in a session variable ... so that I need not to query again and again
Session["ds"] = datasetname;
Everything is fine but when I am doing export to excel ... where at last after the export is completed I am calling the method in try/catch
try {
Response.End()
}
catch {}
But due to this, my session variable (ds) is getting expired and when I am using it next there is no rows and hence my page displays no data.
I tried going through internet and found that this is a bug it seems as identified by Microsoft and they have provided a hotfix for this but in Windows Vista .... I am running on XP.
