Asp.net - Adding A Session ID To A Link For Automatic Session Start?

Dec 8, 2011

I 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.

Asp.net - Can't Get Session Variable

Jan 14, 2011

Partial Class Preferences_MyPreferences
Inherits System.Web.UI.Page
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.

Asp.net - Using Session Variables In IE?

May 14, 2012

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.

Rec_IDs = Session("Rec_IDs")

PHP Session When Using Desktop App?

Apr 11, 2010

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?

Session Timeout In ASP.NET

Jun 7, 2010

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.

.net - Difference Between C# And Console Session?

Mar 6, 2012

Ok, so I have this code written in C++ that call the function SetThreadDesktop. I call this function from a dll when running as System user on Windows XP.

When called from a C# console application, the function succeeds, but when called from a VB.NET console application, it doesn't. With GetLastError, I saw that the error message was this:

SetThreadDesktop failed with error 170: The requested resource is in use (translated from french)

How does it come that it works for a C# console app and not for a VB.NET one? Btw, it doesn't work for a winform app neither. Is it a compiler option that I have to change?

.net - Guesses Of Session Value Conflicts?

Mar 25, 2010

I have a asp.net web form which will submit information to come as emails. Whenever user fill the form and click on submit button,the information user entered will be sent as email.This web form has 4 page. but the web form will not use all 4 page on all requests.

if the user select a particular value in first page, the form will bypass the 3rd page and go the last 4th page(like...page1,2,4). IF it is any other values selected in the first page. form will navigate as page1,2,3,4.

So now my problem is when multiple users access the same website, the value in the first page get combines from different users and the form will act abnormally.Sometime it will bypass sometimes it will not bypass the page3

Show below is the variable decalrations:

Public strRoleType As String = String.Empty
Protected Shared isAreaSelected As Integer = 0
Protected Shared isStoreSelected As Integer = 0
Protected Shared isHeadOfficeSelected As Integer = 0
Protected Shared isRegionSelected As Integer = 0

I guess the problem is with strRoleType variable whether it is getting values from different users.

.net Issue With Oracle Session?

Mar 6, 2009

i noticed in vb.net that when declaring new connection objects it creates a new session. and sometimes it reuses an existing one.is this an expected behavior?

in my application i created a global temporary table. in oracle, this acts like a table but session based. the behavior mentioned above is causing some issues with my temporary table as new sessions are being created and thus, i'm not able to get the desired data from the table.i thought of using a global connection but not sure if this is the best way.

Asp.net - Finding All Use Of Session State?

Feb 3, 2011

I'm looking for some smart ideas on how to quickly find all usage of session state within an existing asp.net (MVC) application.

The application in question was the subject of outsourced development, and has been running fine in production. But we recently realised that it's using InProc session state rather than (our preferred route) StateServer.

In a small scale test, we switched it over to StateServer, and all worked fine. However, when we deployed to production, we suddenly experienced a large number of errors. I'm not sure if these errors were caused by this change (they were actually complaining about database level problems), but removing the change allowed the application to function once again (this may have just been because it caused a recycle to occur).

So before I try switching it again, I'd like to perform a thorough audit of all objects being placed in the session (I'd previously taken a quick look at a couple of controllers, and they seemed fine). If I had full control over the code, this is the kind of place where I'd just comment out the class (to compile and find the various ways of reaching the session class), then comment out the accessors, hit compile, and visit each error. But I can't do that with built in .NET framework types.

I decided to try using Reflector. I've analyzed the "Used By" for each of the following:

System.Web.HttpSessionStateBase.set_Item(String, Object) : Void
System.Web.SessionState.HttpSessionState.set_Item(String, Object) : Void
System.Web.SessionState.HttpSessionState.set_Item(Int32, Object) : Void

Asp.net - Generic Dictionary In Session .Net?

Aug 31, 2011

I have a generic class called SessionManager to control the types of variables I store in session. I have been doing it for String, Integer, List(Of T) without any issues like this.

Public NotInheritable Class SessionManager
'''<remarks>
'''Private constructor to prevent instantiation of, or inheritance from, this class.

[code].....

I would like to do the same for Dictionary(Of T, T). I would like 2 generic private methods for Dictionary(Of T, T) for getting and setting; GetFromSessionAsDictionary and SetInSessionAsDictionary. (When nothing returns empty dictionary like the List(Of T) properties and sets in session) And this should allow me to create as many public properties of Type Dictionary (e.g. Dictionary(Of String, String), Dictionary(Of String, Integer)) as possible to store in session.

EDIT:This is what I have ended up doing after trying to make it generic Dictionary(Of T, T), and it works without any issues. What I want instead is a solution that would not constraint the type to Dictionary(Of String, Integer).

Private Const _Dictionary1OfStringInt As String = "DICTIONARY_1_OF_STRING_INT"
Public Shared Property DictionaryOf As Dictionary(Of String, Integer)
Get
