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.
On startup of my software which i developed in vb.net, it connects to mssql server. I want to have session id or session number of the connection with mssql. I'm sure it is unique number and i want to use this session in my software for different purposes. My question is
1. is there anything like session id or session unique number when you connection mssql server
i have 1 master page with 5 pages that call it. now on the master page, I have few dropdowns and textboxes, and the calling pages only have a small article in the corner. I want to start a session on page_load event, so that if the user chooses to select a dropdown or put data in textbox, even if he clicks on the other 4 links of other pages, the data should stay.how can this be done?
I want to launch a browser session from a Windows App to load a specified file using system.diagnostics.process.start("http://www.abc.com/doc1.doc") but I'd also like to specify that there shouldn't be a toolbar etc. on the browser window. Is this possible?
I have a session which contains a datatable and also have a function which returns a datatable. I need to add these two. How can I do this? The below code is to be replaced with correct code.
Session("Table")=Session("Table")+obj.GetCustomer() where obj is an object of the business layer.
The '+' sign cannot be used to add these two, so how can I do this?
I have a page, a session starts on page load (using global.asax) the user may not move from (or interact with) that page for a long while and I dont want to increase the session timeout. When the session times out after say.. 20 minutes, I want to start a new one, without moving from the page. I also don't want constant keep-alives i want to do it via another method (timer, button press...)
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.
I have an 2-d arraylist with 2 fixed columns and dynamic rows. The arraylist will be assigned to the session variable at the end of the code below. My question is how can loop thorugh the arraylist from the session to get its value?
If .SQLDS.Tables(.sSQLDSTbl).Rows.Count > 0 Then Dim NoOfAdjType(1, .SQLDS.Tables(.sSQLDSTbl).Rows.Count - 1) For iRow As Integer = 0 To .SQLDS.Tables(.sSQLDSTbl).Rows.Count - 1
We have implemented exam on a single page and store the option in view state as users selects the same. On select of next question page is loaded again. Sometime "If Session("User") = """ turns out true and user logs out.I did setup session on first time page load as
Session.Timeout = 340
Also in web config file session timeout is 2 hours.

Three buttons-ABC,CBA and Show. if you click on ABC and then Click on Show button The textbox shows "ABC" but when I Clicking on CBA button And then Click on Show button The textbox shows again "ABC". IsPostback property will true on each time the page is posted to the server. So the session reset the value.
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.
Dim Rec_IDs As New List(Of String) Rec_IDs = Session("Rec_IDs") and Dim Rec_IDs As New List(Of String)
Protected Sub login_Click(ByVal sender As Object, ByVal e As EventArgs) Handles login.Click Dim querystrings As String = "Select Email, Password ,Roles, Nama_Depan, Nama_Belakang from Employee where Email = @email;"
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 am using visual basic ADO reference to connect to Teradata database. In the code I hold the metadata in the volatile table, However after fixed number of SQL execution statements the session changes thus erasing all the data of the previous session stored as volatile tables. Is there a way to keep the session same during the execution of the code.
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.
I have an aspx page with a button, the user clicks the button a session variable gets set, I then read the session variable later. here is an exaple of my button:
I programmed my website using visual basic code (via microsoft expression web) and need to post information to a remote location using a php page. How do I take variables from my visual basic code and transfer them to my php code? I was thinking sessions would work, but I haven't figured it out yet.
I am building a User Management section to a website CMS.The user has a list of users and then clicks the edit button, the system then stored the UserId in a session and goes to the editUser.aspx page which will show the users details.To get the users details I need to convert the UserId session to a Guid so i can get user details.
I keep getting error message:
System.InvalidCastException: Specified cast is not valid.
Dim selectedUserId As Guid = CType(Session("strUserId"), Guid) Dim mu As MembershipUser = Membership.GetUser(selectedUserId)
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?
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.
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.
In my project I am using a session table. I am binding this session table to the gridview,in gridview row updating event.I keep the records of session table to a datatable and I use the code below code for updating:
My problem is when using PageIndexChanging, I can edit in the 1st page of GridView without any problem, but in second page it is editing the one corresponding to e.RowIndex in the first page, so no change occurs other than the first page in the gridview.
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:
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
