I have a Session Varaible in which I am assinged a List of "MLoad" objects (Ex:- 10 MLoad objects) from the initial search. After that basing some icon click i am trying to get the new filtered results (Ex:- say 1 MLoad object) and assigning them to the public property "ListSearchResults" (See code below). When i do this the original results in the Session are changed(10 MLoad objects are getting replaced with 1 MLoad object ==> which just been filtered). What i have to do so that the "ListSearchResults" in Session is not changed. It is now byref, how to make it byval?
in acreate an object See below code and after retreving t
We have a common problem with tabbed browsing in Internet Explorer is that the session state is shared between the tabs.
Due to this our user can face many issues like
1) Suppose user has opened a .aspx page for (clientId=1) and editing it in one tab and at the same time user is editing another client(ClientID=2). And both are using same in session.
Due to the session sharing when page will auto refresh the first tab with (clientId=1) will see the data of clientId=2.
Its clear that the session is shared between the tabs.
I have also implemented the ASP.NET 2.0 offered solution by way of the following config setting <sessionState mode="InProc" cookieless="UseUri"></sessionState>
But still our users are facing this issue. I am looking for solution to disabled the Tab programaticaly and also i wanted to know how to clear the cache programatically.
I am doing a POC of making my website run faster. Currently it stores huge object data in Session while passing information from one page to another. What I was thinking is to use shared methods and properties instead of session. It works, but wanted tocheck if this is an optimum way to do it. Below is the code that does not use session but still pass object data from one page to another:
my understanding static/shared objects will be saved in a memory that is shared by all instances of the asp.net application,so if we set a value to shared object from inst1 & i should be able to access it via instance2(may be in same computer or anywhere)Actually:In my vb.net application,previously they defined shared dataset to hold some information specific to the user,still now i cant reproduce the error that same value shared across all application instances.Please help me to solve or clarify this.

I dont know if im writing in a right place. this is about class in App_Data (asp.net) folder that i want to user throughout system. but specifically for one user.
lets say userA login to the system. then system will use classUser FillProperty and set variable like Name, Username, UserId (a property of his own, the modifier is shared). the purpose is so that it can be used in any page. it behaves like user.identity.name (when we want to call name of user that already authenticated)
I can do it fine. but once i test login with UserB in other browser, it change that shared variable with property of userB.what i want is, when A login, he will set the classUser with his data and data that called by him is his data. and when B login, he will do the same, but he will use his data without replacing userA data.here is the code :
I have several web applications on a server using the same application pool. The worker process usually takes a lot of ram but usually only from one application. I can successfully limit the cache usage by setting "PrivateBytesLimit" in web.config file when the application uses it own dedicated application pool.
Does anyone know how this setting will be applied when using shared application pool? Is it per application, per worker process or per application pool? Also if it is not per application which setting from which application will be applied?
We have an applicaiton that was converted to the new framework using the wizard in Visual Studio 2008. When we install the applicaiton in production and change the iis settings to use the 2.0 framework we start to see these errors in the event viewer on the web servers. We are using SQL Server Session State and have 3 web servers in a load balancer. Object reference not set to an instance of an object.</Message><StackTrace> at System.Web.SessionState.SessionStateModule.PollLockedSessionCallback...
I have a problem.This particular code when used on local machine is working fine, but when it is used on serverit gives an error like " Object reference not set to an instance of an object.Exception Details: System.NullReferenceException: Object reference not set to an instance of an object._isRefresh = _refreshState == (bool) Session["__ISREFRESH"]; "

I had an xml-serialization which worked fine, but as I have just knew it doesn't work in Opera browser. I think, it's security rules don't allow to write to cookies xml-content.What can I do? Can I use binary serialization or something else?
Anyway, I currently have a ajax based progressbar, which works like this: my long-task stores progress in session. Async callback retrieves progress from session, progressbar is updated. Everybody is happy... not! This only works when the "main loop" of the time-consuming task runs in either codebehind or a class with httpcontext. But all my businnes objects cannot do such thing. So, the next natural spet would be to say "move it to a static class" ProgressHelper or something, but since static classes are shared across all appDomain, I would bump into concurrence problems. So, can i have say a "static list progress" say progress["session1_progress"], progress["session2_progress"], progress["sessionN_progress"]? I cannot really see a way to update progress from inside a task in a business object, which i might want to use also in other plattforms like a desktop app?
I wish to persist a class object across postbacks by using a single session variable/object/whatever.
The class has about a dozen single variable properties; and about a dozen table properties; and several methods. The main table tracks rows of sporting event results. The web site will collect one row at a time for each postback. The data in the object's constructor is based on a dataset, but the data in the class will grow each time I do a postback so I don't want to loose the information in the class. The data isn't very big - it will fill a single computer screen.
Being new to programming I am thinking that I can store the dataset in the session but that would slow down the response time because I the methods would have to be called to refine the data - or maybe I can just store the entire class object in a session.
I am working with asp.net mvc and i am trying to get acces to a object that is in the cache.In the Application_Start() of Global.asax.cs i create and store an object in the cache like this:
Translator translator = new Translator(); HttpContext.Current.Cache.Insert("Translator", translator, null, System.Web.Caching.Cache.NoAbsoluteExpiration, System.Web.Caching.Cache.NoSlidingExpiration);
Translator holds a dictionary with translations.Now i want acces to this object from the cache to use functions and get values from the dictionary.I know i can acces it like this HttpContext.Current.Cache.Get("Translator") or Cache.Get("Translator") in the views But how can i use the functions of the object ? The meaning of the cache is to have a object that is accesable througout the webapp right ?
Do i have to make an object and asses the value of the Cache.Get("Translator") to it, so i can use the functions or is there another solution?
On my local machine I've got a website running which uses the login control to authenticate a user and write a formsauthentication ticket to the client (which is also on the same local machine). At the login process it stores a a small serializable userobject in a session object named Session["appuser"]. Now when I open FF and login to the website all is fine so far... But here's the thing I cannot for the life of me figure out...
When I open IE8 and login to the same website, the session object which was created in FF is completely overwritten with the one created in IE. I thought that every session is unique, but now I'm really starting to feel my knowledge of sessions is almost next to nothing... Is there anyone out there that could tell me why I'm seeing this.
When I try to save an object reference in a view state it tries to save the object content using serialisation. to save the object reference only to apply to this object instance after postback?
I have a object of Class named "Employee" I need to store the object in the session. what happens if i do not serialize the object and store in the session.
I have a Authorizeclient.aspx.cs page where I set my session value.Authorizeclient.aspx is a blank page. HttpContext.Current.Session["nodeID"]="0". This session value changes from 0 or non zero which depends on the value returned by Database. If no value is returned I assign HttpContext.Current.Session["nodeID"]="0" as the default state else I assign HttpContext.Current.Session["nodeID"]=resolve(nodeID).ToString()
Till this part it works fine as expected. However, I have a requirement that I need to read the nodeID from Session in other application on the same server. I mean this application too is part of the root project where I initially created the Session and set it. The strange thing is the Session["nodeID"] in application gets null "SOMETIMES" Not always. I am trying to read the Session in Page_Load. Sometimes it works fine and sometimes it gets null. Moreover the session object do not die and I can see other keys like Session["Themes"] etc there. The session is in InProc mode and have 20 minutes timeout time.
I am stuck with the issue of concurrent access to Session object. Actually my problem is i m writing to session in frame1 and trying to access that same Session object at the same time in Frame2's Page. I know about the reader/writer lock. I made the enablesessionstate = readonly in the page where i m writing to session. its giving me strange behavior on IE and firefox.
Its working concurrently in IE8 ( means page2 is diplaying modified values while page1 is changing the session object) but does not work in Firefox even page load is not called untill function on page 1 completed. Either anyone can fix my issue with firefox or there is new solution to reader/writer lock so that i can read the session at the same time while writing.
