I just upgraded one asp.net 2.0 (using vs2008) app to asp.net 3.5 (using vs2010) but session do not work. (pass a value from one page to another page)
I used code in web.config file as below.
<sessionState mode="InProc" stateConnectionString="tcpip=127.0.0.1:42424" sqlConnectionString="data source=127.0.0.1;user id=sa;password=" cookieless="false" timeout="120"/>
i am working on asp.net website.
on my web page i submit some data on click at button , this block is inside update panel.
this functionality working fine in 3.5 frame work.
Now our website is using 4.0 frame work.
controls inside update panel giving following error on submting data :
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerServerErrorException: An unknown error occurred while processing the request on the server. The status code returned from the server was: 500.
I've just upgraded my development machine from XP SP3 (IIS5.1) to Win7 x64 (IIS7.5)
Since doing this, my app has started to behave differently. Within it I store users' preferences/access levels using an instance of a class that I store within the Session object. This class is shown:
[Code]....
My requirement is that on each page request (other than the login page), the application should check that the Session object exists. The page data is therefore shown based on the values within the session object (e.g. which customer account they are using etc)...Previously on IIS5.1 if I was logged into the app, but made some changes to a file within App_Code, or Web.Config for example, when I then continued to use the app, I would get kicked out to the login page straight away. This is the intended behaviour. Now however, on IIS7.5, the app continues to provide access to the pages, but debugging shows that the session value has had all of its values set to 0 (zero). Therefore, the pages continue to load but the data shown is corrupted because the app no longer displays it accurately. Here is the code I use which (on IIS5.1) caught this occurence. Can anyone offer any advice on just what's now happening
[Code]....
I have tried changing this line:
[Code]....
i am still new to using session state, i want to convert page name into and integer according to a database table a function then compares "X" and "Y" to check if a user have the right to view this page i know this is not the best way of managing website security, but it is like "training on how to use the session" what have i done wrong

I have an uploadify control working fine in a vb.net web application - however whenever I switch on cookieless session state in web.config (cookieless="true") - it stops working.
In my upload IHttpHandler I can see that the data stored by uploadify is nothing:
Private Function Process(ByVal context As HttpContext) As String
Dim File As HttpPostedFile
File = context.Request.Files("filedata") ' Nothing
Dim FileExt As String = context.Request("fileExt") ' Nothing, etc

View 1 RepliesEnvironment used - Asp.net mvc 1.0 with c#
Problem -I have used simple mvc application. and also added webform into mvc application.and it is working fine. but when i used session object for sharing data between mvc and webapplication. it is not working. I have put Session["logon"] = "logon"; object into mvc controller and when i access this into webform then there is no value in session object.
In my project I have configured .NET's sessions to go into database.
I also have a global.asax which implements Session_Start().
In Session_Start() I write three things to the session:
The time the session started.
The user's host address.
A serializable device object wrapping the user's agent.
The problem is now that users which don't allow cookies won't allow session cookies either.
(Easily reproducable by putting the site URL to the restricted sites of IE).
If I keep on refreshing (put finger on F5) a new session is created for every request (-> no session cookie). Shortly, the web server process grows to some hundred megabytes.
It does not matter if you use IIS7 or Cassini Local Webserver.
The issue is now: the memory does not get released until the sessions time out. What is the logic here if sessions should really go to database? How long will .NET keep them in memory? Eventually, you'll even get Out Of Memory exceptions!
Anybody know? How to detect and prevent such (almost malicious) "attacks"?
I have an asp.net application with c# language. I have a common class which maintain the constants and static variables and fields. I also have a login page. If the user logs in successful I set IsLoggedInSuccessfull as a static boolean variable in common class.
My question is: Will this only work for a specific user session or for overall application ?
Edited:
Based on some answers I got another question here.
let say i am using the Static method as Authenticate(User objUser). intention is to call this method when user clicked log in button. where on login button I am let say prepare the User object with certain parameters required for login, then passing to this method. what would be the impact there? let say I have single server for now (no server farm or garden). then there will be the single application level method to authenticate the user, right? and say 10000 user are going to logging in to this site/application then how authenticate() method comes in behaves ? will CLR automatically manage threading there ?
I got the viewCustomer.aspx page sending parameter to EditBusiness.aspx page as per below coding .
After that i retrieved to EditBusiness.aspx.cs by using (Request.QueryString["customerId"] ) and save in session . Then i tried to use the session in the EditPersonal.aspx and EditOther.aspx is worked but then back to EditBusiness.aspx the customerId parameter is disappeared . I believe is because in EditBusiness.aspx.cs using string customerId = Request.QueryString["customerId"] . Even I have tried cookies but its doesnt work .
ViewCustomer.aspx.cs
protected void grdCustomer_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName == "Mod")
{
Response.Redirect("EditBusiness.aspx?customerId=" + e.CommandArgument.ToString().Trim() + "&mod=Modify");
}
EditBusiness.aspx.cs
string customerId = Request.QueryString["customerId"]
Session["customerId"] = customerId.ToString();
EditPersonal.aspx.cs and EditOther.aspx.cs
string customerId = Session["customerId"].ToString();
qry = "select *from customer where customerId = " + customerId;
I am developing a intranet site and want to track the users, I am using session for this purpose, I am using windows authentication mode so there is no login form here. When a user clicks the url for the first time a new session is created and at that time I am adding a entry in a table(say :Users) with username and logintime and sessionid etc. Below is the logic Iam using in form_load event of Default.aspx
If session("user") is nothing then
---create new session (at this point I am adding a entry in table(users))
Else --- use the same session and continue the work.
End if
When I check the users info in the table some entries are created with same userid and same sessionids with different login time, how this is possible. I just want to know who is logged in and what time.

I'm administrating servers running IIS 6, hosting a website on ASP.NET 2.0. Yesterday I installed .Net framework 3.5, and all my user authentication system was lost. Users can't log in, because their password arn't getting authenticated, maybe because the hash function has changed in 3.5??? I can't really get to the code, but I know it uses an extention called CodeSmith.Do you know of any break my upgrade the 3.5 ugrade could couse?
View 1 Replies I have to get the value from a textbox (not bound) that has been put into a formview control. The Submit button also resides in the formview control. I have this code in the button's click method:

to get that value entered and store it into the enteredValue variable (and yes, I know I have to do validation, etc). But when this runs, the value of the text in the textbox is "". I tried to put this up in the page load event, but then I get an error about declaring New.

i created a web setup project for my asp.net application. am trying to create an upgrade MSI that will only replace some few files in my initial installation (very minor upgrade). right now, am not getting it right because the whole initial set of files is been replaced. i guess i only need to change the package code, but i cant do this in VS.NET 2008.
View 6 RepliesWe currently have two web servers that are load balancing a website. Each server at the moment has its own copy of the site on their own hard drives. We have recently installed a SAN thats accessible by both servers so what I would like to do is move the website files on to the SAN for easy management of upgrades to the site. What steps should I take to ensure this works correctly with IIS7 and the web.config files and possibily machine.config files. For additional information the web.config's on each server is currently encrypted, how would I be able to achieve this with a SAN?
View 2 RepliesI have a website I developed in VS 2008 targeting .net 3.5. It has worked well. I recently upgraded to VS 2010 and needed to make a few changes to the site. However, I'm receiving compile errors (haven't made any changes to the code yet--was just launching the site to make sure it worked ok). I get "Contains" is not a member of system.array. Everything I've read states that the contains method was added in .net 3.5, which I know to be correct because it was working in VS 2008. I've been targeting .net 3.5 in VS 2010, but it still isn't working. I also used linq quite a bit with linqkit to do dynamic queries and all of my linq queries were saying my queries weren't queryable (I don't have the actual error in front of me). Anyway, to fix that one, I had to import system.linq (I previously had system.data.linq and it was working fine). To reiterate, I haven't targeted my site to .net 4 in VS 2010, I've left it targeting .net 3.5.
I tried converting my arrays to arraylists since arraylists were still pulling up with a .contains method, but then it broke my linqkit queries when I ran it on the site.
Here is my linqkit query:
Dim str() As String = archlist.ToArray(GetType(String))
Dim str3 As New ArrayList
str3 = ArrayList.Adapter(str)
predicate = predicate.And(Function(l As CompatTesting) str3.Contains(l.application.cpuarchitecture))
Before, I didn't have the arraylist conversion, I just had str.contains and it worked great to generate a sql "in" statement. Now after using the code above, the site launches, but when I actually run the code, I get Method 'Boolean Contains(System.Object)' has no supported translation to SQL. I also tried upgrading my linqkit dll to the latest version but it didn't help.
My questions are, since I'm targeting the same .net 3.5 framework in 2010, why is it not allowing me to use array.contains anymore? Maybe if I can address that issue, it will fix my linqkit issue where it says "contains" has no supported translation to sql.
