Preventing Multiple Logins?
Nov 24, 2010I'm using the "cache tecnique" to prevent multiple logins. Reading in this forum I have read the following code:
Global.asax
[Code]....
Login.aspx
[Code]...This code works fine, If the user is already logged the second login is not permitted. But....
But if I make the logout (destroing all my session variables) and I try to login a second time... it's not possible, I read that the user is already logged!!I have also tried to clear the cache after the logout but nothing changs, even if it is illogic because the code must work even if I don't do the log off...

State Management :: Avoid Viewstate In Page Load Event?
Aug 30, 2010I haveMaster Page -> ASPX page -> User ControlUser control page is contains all dynamic bind controls (e.g Repeater) depended on ASPX Page (Only one parameter say ItemNo)The problem is, if I bound user control on page load event with passing respective parameters then it's create to much view state (I checked source file and it's almost 1.5 MB)In other way if I put one textbox, and a command button and I pass required parameter on button click and load the control then page size is ok (I checked and it's < 500KB)
View 2 RepliesState Management :: How To Manage Multiple Sessions From The Same Pc
Aug 30, 2010#Newbie alert# Only 8 months experience with school education back in 2002.
I'm using VS 2008, C# 3.5 to develop my own login system for our company website.
Originally we have a "simple" design which only had a login and order page.
That order page needs to be opened for 10-12 hours at the time while our stores are opened without having to relog into the system for each query.
We also have a requirement that some users need to access 2 different compagnies (separate inventories) which require 2 different logins.
I solved that "cross over" session problem by moving all the values into viewstate with my own viewstate manager class right after the login.
Now my problem is that we are adding more and more pages and I don't want to be stuck with the problem to resave the viewstate to session and then back on viewstate for every menu items and buttons.
Is there a way to create some sort of items list of all the sessions opened by the user and only transmit that from pages to pages?

View 5 RepliesState Management :: Multiple Servers - Data Lost
Apr 16, 2010I have 2 front end servers and 2 back end servers. There is a registration form in my web application. The registration form uses a Microsoft Wizard control. Lets say the Wizard control has 4 steps. After the fourth step, users click "Finish" and I display the "Thank you Message". The way the request is routed between the 2 servers is round robin. So lets say till the fourth step, the response comes from server A. After the user clicks "Finish", lets say the response now comes from server B. After they click "Finish", I am trying to access some information in the Wizard control (like Name, address and so on). Because the servers are now switched, the data is lost (at least thats what I think is happening). So all entries in the wizard control are now blank and when I try to read those values, they are null.

May 26, 2010I am sorry if this is been discussed earlier. I am having a problem maintaining the session when someone uses the same browser with multiple tab, the results gets messed up. A perfect example would be, [URL] if you open IE (or any other browser) and open two tabs and search for two different air travel itinerary and the results will completely overlapped (real mess).

State Management :: Multiple DataTables In Memory - Best Practice?
Jul 9, 2010I have a DataTable which holds information on truck routes. When the user click on a route it display another table with details about the stop along that route. When they click a stop it shows what items were picked up at that stop. Three separate pages with 3 distinct DataTables. Currently I am storing them in the session. Normally, I would use the view state since the data only needs to live on that page. The reason I use the session is because each page is part of a Master pagelayout. There is an export button in the master page which gets the data in the session and exports it to an excel file. The issue is that when the user goes to the item level detail and uses a quick navigation link back to the route information the data for route is not reloaded into the session, just the page. If the user clicks export it will export the data set from the item level detail even though it is not displayed on the page

Feb 16, 2010I have a problem with membership authentication. I have two websites, website1 and website2, and both of them uses forms authentication with SQL membership provider (SQLEXPRESS). I have two scenarios:
Case 1:don't publish the website1 and try to login website1 with user1 -->Works ok
don't publish the website2 and try to login --> it displays the previously logged in user (Website1 user)-->Perfect
Case 2:publish the website1 and login-->works ok
publish the website2 and try to login--> it does not show up the site1's logged in user (No idea why)
then login into website2 and open website1-->it does not show up the website2 logged in user or any user...It looks like something wrong with cookies....

State Management :: Class Object Available To Multiple Events In The Code Behind?
Sep 1, 2010I am trying to incorporate AJAX in my web project for the first time and it isn't working. I don't know how to instantiate a class once and use AJAX to update the dataset numerous times before updating the database changes using a postback.
My project is to learn AJAX with a class object. Clicking the button is supposed to increment a count by one using a class to store the count. Here is my class:
[Code]....
Here is my HTML code:
[Code]....
And here are my button click event code snippets:
[Code]....
My problem is that as I step through the code (after clicking on the second button) it instantiates a new class object each time which returns a value of 2 every time. I have tried to fix the problem by putting my counter class instantiation in the pageload event using "If Not IsPostBack Then ..." but my probem there is that the button click event block of code would not recognize the cCount class - it put the blue lines under the cCount
My goal is to have the class object available to multiple events in the code behind: especially using AJAX to build records in one of my DataSet tables Does anyone know how to handle this?
State Management :: Session Variable And Multiple Web Application Instance
Oct 13, 2010I have a web application using window authentication. There are a search page and a edit page in the application. In search page, user can enter some search criterias in the textboxes and the search result will be displayed in the gridview by clicking the "Search" button. User can select any row from the gridview and it will take him to the edit page. In the edit page, there is a "Back" button to take the user back to the search page. I use session variables to remember what the search criterias the user entered in the textboxes and what page number the user was in the gridview. So when the user goes back to the search page, the textboxes are pre-populated with the search criterias and the gridview is displayed in the correct page number.
The problem is: If user1 opened one browser window and did a search using search criterias1, then user1 opened a 2nd browser window and did a search using search criterias2. When the user1 went back to the search page from the edit page using the first browser window, all the textboxes and page numbers are from the 2nd browser window, instead of the 1st one. Can anyone explain this problem to me and how to prevent it? It will be helpful too if you can give me some links about the similar problem. I am thinking if the same user logged on two different machines and did the search on each machine, what is the result?
