Currently, in my web application I have a listbox that gets populated client side (via java script) with a set of ids -- we'll call this page 1. Server side, I am populating a variable with the ids and passing it through a query string to another page -- we'll call it page 2. Now, I have a previous button on page2 which allows me to go to page 1. I'm trying to figure out how to repopulate the listbox on page 1 with the values previously selected. I was thinking of just storing the set of ids in a session variable and using it client side to repopulate the list box. Can anyone advise on how to access a session variable client side? Here's some snippets of my code...

Is there a way to set session variables during login that are then available to reports? We have a reporting services server where we move and denormalize data from our transaction system for reporting purposes. In order to allow our users to login with the same user name and password from the transactional system we have set up custom forms authentication and after much trial and error it is finally working. In addition we have the authorization accessing our transactional system so that any changes in user authority is immediately reflected in Reporting Services.
Our problem now is that we would like to add some additional features such as locking down parameters depending on user authority/groups in our transactional system. We have found a way to do it but it's inefficient, basically we have stored procedures that will query our transactional system to check for access. The problem is that these queries will often be run for every report request even though the answer is unlikely to change. It would be nice to have access to session level data that can be set once during log in and then accessed from the reports.
the dropdown list is showing data from database, but how to retrieve the selected value and store it in a session variable??

I'm using this code to retrieve the list of files from a FTP server
Dim request As FtpWebRequest = WebRequest.Create("[URL]")
request.Credentials = New NetworkCredential(username, password)
request.Method = WebRequestMethods.Ftp.ListDirectoryDetails
Dim response As FtpWebResponse = request.GetResponse()
Dim responseStream As Stream = response.GetResponseStream()
Dim reader As StreamReader = New StreamReader(responseStream)
messagebox.show (reader.ReadLine)
It gives me alot of information that I dont need, I know that I can use:
request.Method = WebRequestMethods.Ftp.ListDirectory
Which only retrieves the file name but when I try to change it, it gives me an error. Error number 550. ListDirectory so I can only get the file name?

The problem emerged when I tried to retrieve data from the database with the help of SqlDataReader and save data from every row to a list (Customer) with the help of Add-method. It turned out that eventually the list had correct number of objects, but the information was the very same in each object of the list.

View 1 RepliesI am storing a session variable that a user types into a textbox. With their valid input, their session gets created and they get a little more functionality than the regular end users of the site.I was wondering if it is possible to find a way to add someone's session variable to the end of a URL. This way we can email a link to one of our clients, they click it, and their session has automatically begun. They already have the textbox to enter their code into, but I was told that it would be much easier for the users to just click a link that will start their session.

Dim userID As String = Session("UserID")
This is just a page in asp.net. I want to be able to grab the Session("UserID") but every time I try, I get this error:
Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive. Please also make sure that System.Web.SessionStateModule or a custom session state module is included in the \ section in the application configuration.
If I put that Dim userID inside say the Page_Load Event, then it works fine. Why does it have to be inside an event? I want to dim it once, and use it throughout the page.

I have an ASP.NET application that I am developing. I'm using session variables within the app.In Firefox & Chrome, they all work.But in IE (ver 9), there's one variable that's not working. I'm not sure if it's a storage or a retrieval (or both) at this point. The variable in question that I'm storing is a List(T) type. It's the only one of it's kind that I'm using. Can't help but think there's a correlation there.One other old post mentioned the possibility that cache is causing the problem, but I didn't understand the answer very well.

how to POST to a php file form a vb.net app: http:[url].... So now I've logged in the user user by posting their username and password to the php file, the php file then does security/checks they exist/etc and if both username and password are correct is stores the user ID in a session variable.Now if the vb.net app tries to download data off a page which needs the user to logged in, it checks this by doing:
if (!isset($_SESSION['uid'])) {
header("Location: index.php");
}
However after having logged correctly in the app the session variable is not set.How does session work with a vb.net app like this?When the user logs in successfully should I download the user id and keep it in the vb.net app and then post it to each page that requires authentication?

I have written a page with an iFrame that basically cycles through a series of internal pages on our server displaying daily activity for our company. The problem I think is that it sporadically loses its session and redirects back to the login screen to keep losing its session which is the default behavior for anyone on our site trying to access a webpage without being logged in.
I have set the session timeout to 4hrs, the iframe cycles through 6 pages anywhere from 10 seconds to 5 minutes on each, and I have even set the META refresh on the page to refresh every 3 hours. I don't understand what else could possibly stop this page from staying active.
