View 4 RepliesI want to control the login user to access our system. I authenticated all of users by using my own way in project. and I want to limit the number of user to access the system cncurrently. It means , We sell our project to customer as Licence software. If user buy it for three users, we will allow three conurrent login user to access the system. Our system allow our customer to create their own users as they wish. We don't want to control the user creation to use the system. but But we want to control the total no of current login user at the server as per our licence agreement . After reading some article, I see there are two main ways to control the no of users.
One way is to use the membership property in my project and then can count the number of online users by executing Membership.GetNumberOfUsersOnline Method.
If I use membership property, I think it is not ok at my project. As my understanding, the system will control the user creation if we use the memebership provider. I am not really sure whether I can use membership provider property to get my system requirement or not.

I'm not sure if this is an error or is the right work mode for sql sessions.
I'm working now with Windows 2008 R2 Web Ed. and SQL Server 2008 Web Ed.
When I close my browse and open again a new browser window I need to login again in asp.net application and a new session is created in the sessions table in sql server.
It's this normal? I remember that with Windows 2003 and SQL 2005 this doesn't happend. When I closed my browser and open inmediately a new browser window my session was retained and I could continue working without relogin.
I have a website live in asp.net
now if user closes browser. the session does not get killed.
I spoke with friend and he said that cannot be done as sessions are on server.
but i see banking website who kills session when browser is closed.
I want to know how can I write custom session management mechanism in ASP.NET. I do not want to use cookies or URL to have my session ID thus I think I can not use SessionIDManager. I will like to save the sessionID in a post variable and at server I will like to extract this ID to map with session.
View 3 RepliesI have been spending a better part of a week trying to track down why I am not able to clear all session variables in a web app (vs 2010, vb.net). What I have tracked it down to is that when I remove or abandon sessions that my html pages or codebehind access, it works, but for some reason in any of my class files where I use "Public Shared strConnection as String = HttpContext.Current.Session("strConnection").ToString" to access a session variable, it finds the old one and not the current one. I have to wait for it to time out, go in again, and it will find the new one.
I do not use Linq, and there is only one place in the whole web app that I place the connection string in a variable whcih is when a person logs in. It points them to the correct database. The sqlconnection is set for all of my listviews in Page_Init to make sure that they aren't using any session variable that they create on their own. Interestingly enough that if I use debug to go in each time, exit debug, enter debug again trying to access a different database, it works correct each time. I assume that debug is correctly killing the session variable for the classes for me.
Physican is accessing data for patient #1 using ASP.NET Web site with backend SQL Server database. Session state is used to persist some patient information. At the same time, he checks his email and clicks a link in the email that launches the same Web site to check on a communication concerning patient #2. In IE8 these two instances of the application share the same session id. If physican responds to communication concerning patient #2 and returns to patient #1, he will now be accessing data for patient #2.
I know about framemerging etc. but how can I launch a new browser session from the hyperlink in the email without closing or stepping on the http session for patient #1 and without having to resort to cookieless sessions?
First of all here is my code chunk.
[Code]....
Right now I am creating this session with the session key "PhonePart" which is also the name of object I am passing in as a parameter in first method. In subsequent methods, I use the the same name to retreive and clear session value. My problem is, this approach works fine If I instantiate a single object of the class where these methods are defined and using that object call the methods, but when I create another instance of the same class and calls for instance method AddToSession and pass that instance, it overwrites the session value stored by the first instance of the class as the session key is the same that is "PhonePart".
Considering this scenario, is it possible that I somehow grab the name of the object as string in the calling method say "AddToSession" and create a session with that name? If Yes, then I can do the same in subsequent methods and retreive session value and also clear the session specific to that instance name without affecting the other session values stored by other instances.
I am sorry if this is been discussed earlier. I am having a problem maintaining the session when someone uses the same browser with multiple tab, the results gets messed up. A perfect example would be, [URL] if you open IE (or any other browser) and open two tabs and search for two different air travel itinerary and the results will completely overlapped (real mess). I know the cause for this problem (both tabs uses the same session). I would appreciate if somebody have any solution for this. I am using ASP.NET 3.5/VS 2008/VB.NETI will not be able to use Viewstate since I use a master page and pre-init event where view state is not available.
View 2 RepliesHow to keep the session variables even after closing the browser?
Everytime I close the browser, I lose all the session variables.
Is there any way to keep them?
I am creating a static variable and adding to session.This variable has value that is user specific. Now I am getting a problem with this users are complaining that they are getting values that should be another users. It's like a mix up with session. Could this be because of static variable declaration?

View 2 RepliesI receive the error message "Error: Your session has expired. Please refresh your browser." When I export a table in ASP to Excel. I know for a fact that the correct data to export exists. Everything works fine except for this error message. I don't see how the session on a browser could run out in a matter of the one second it takes for the Excel file to pop up

View 6 RepliesLets say I am doing a shoping cart. I authenticate the user with a session variable.For example:

// Can I do the following

Now will this Session["Cart"] value which is washing machine here be unique to diff customers?
I need to open a second browser window or tab, but it must have a different session ID.
Opening the new browser window from an ASP.NET page is easy, but then it shares the same cookie and thus session ID with the original.
Problem Statement: I have a details web page which has a unique sesssion ID generated per user. Now if a user does Ctrl + N or File > New Window and opens a new browser instance then the same session ID is genrated and user can update on both the windows differently and this leads to ambigous updates to DB. How can we stop user to open a new window or how can we detect that a new instance of the same session ID has been genrated twice so as to kill both the sessions with a user firiendly message.

View 4 RepliesI would like to have following feature in my ASP.NET 4.0 application (I would prefer C# code):
On the start of application, the code checks
if User == Administroator
then load page1
else if user = customer
then load page 2
I am very new to asp.net. I developed one application. In that I have two pages. First page contains Application.Get() in page load event, here I read this Application variable, initially it returns NULL. If it is NULL, I make some buttons invisible. Then I jump to second page, in that page contains Application.Set(). Again I jump from second page to first page, this time Application.Get() is not NULL, I make some buttons visible.This is ok, if I execute the program in .net software.
But, when I publish this same program to web server like IIS, it is not working properly. After publishing very first time the first page returns NULL after that it doesnt return NULL even I closed the browser. I dont know why. In program, I used 2.0 framework. IIS also has 2.0 framework. Please clear this issue.
Customer were getting "View State Validation Error" due to worker process recycling at our production webserver and to fix that i applied machinekey and then move my Session state Mode from In Proc to State Server to retain session data and not kick out the customer to relogin. I had serialization issue with one object which has to be stored in session but when i moved it out of session i could able to resolve the issue.
But doing all these i was partly successfull in keeping the user in their session when Worker Process recycle event occurs.I was able to refresh the page or make a post back by clicking the refresh button and also able to retain the session values. But the Problem occurs when sending asynchronous request to server which we do periodically every 15 minutes from the moment the user logs in.The web page doesnot update data on website when sending asynchronous request.By Debugging I found at this particular code point it fails to make a postback which is required.
<%=GetHintFromServer%> (When there is no Worker Process recycle i t gets replaced by
WebForm_DoCallback('__Page',message,ShowHint,null,null,false) on postback) Everything works fine when there is no Worker Process Recyling but when it happens looks like sending request asynchronously using javascript fails .Remember When I make a post back by manually clicking submit button everything works fine.

function SendRequest(msg, isBusy, chartMsg, vesselMsg)

}
