MVC :: "Lock Screen" Essentially Logs The User Off
Nov 19, 2010
I'm about to convert an existing webforms application to MVC. This existing system lean too much on JavaScript in my opinion, so I'm throwing around some ideas for a "lock screen" functionality. The user can be busy editing a form....any form, there are tons. "Lock Screen" essentially logs the user off, but when logging in again, they are taken back to the form they have been busy with and the values entered before are loaded. I also will have to provide a way to lock the screen after a certain time of inactivity.
i have a page wherein i need to lock the screen when user clicks on the send email button, but everything is happening except i am unable to see my lock screen page. i have used the update progress for this purpose.. m posting part of the code here .aspx part
I am making a small silly game but I am not sure of the best way to do it or where to start.Basically I will send a link to the people who are going to playing and on that page they will enter their name. I am then going to get an email with their name in so I can see they have accepted my challenge The game will then redirect to the next page. Thats not a problem.The problem is the game is going to played over a month and each time they visit the game on any page the website needs to know which player is the one who is playing.The other thing Is there is going to be a clue button for each question if they click the clue button for that question They will loose points. Now I want a way of of telling if a user was to display the clue close the website then come back and answer it.Is cookies the best way? Or maybe a cookie for the persons name and a server side file for each player so I have a record of who showed clues for what questions?
This is what I have in the RegisterUser.aspx and yet when the admin registers a new user, then on clickiing the register button, the site logs in as the user who was just created.
Nowadays having activity logs of the system is needed for history and if someone who is trying to mess your site, it is easily to define who is it and when it happen. And even Facebook have it.
how to add notification facility same as facebook in our c# website, clients get the notification on their profile whenever any new feature is aaded to website..?
i'm using ASP.NET membership for a silverlight application that makes use of Wcf Ria Services.
my problem is that i don't want multiple logins on the same account and i need to logout the user when he logs in on another machine. (I don't want the account to be used by many people at the same time, and the last who logs in must kick out everyone else)
I want to log out the user when he (or someone else) logs in from a diferent computer using the same user name.
Basicaly i want to prevent multiple individuals from staying loged in under a single user name by signing out the previous users. Any ideeas about how i can acomplish that ?
I was wondering when a user logs in using the login control for ASP.NET, how do we choose where the user goes after? Do we configure this in the web.config file?
I have two roles admin and member. In my application, admin can manipulate most of the member data. I know that in forms authentication a user can be unlocked like,
MembershipUser user = Membership.GetUser(clickeduserName); user.UnlockUser(); Membership.UpdateUser(user);
My questions are,
How to lock a user in forms authentication? Why is MembershipUser.IsLockedOut Property set as ReadOnly? Is it not the right way to LockOut people as an administrator?
We have take over a classic asp site. Everything works fine, but we are making improvements to some reports and adding new reports, so we are doing this in .NET, with that said, after reviewing the secuirty code, there are 2 sessions that are set and used thru-out the site as part of some of the individual page queries.
I know that the sessions are being populated, because the reports that use those values return records.. now with a new report we are working on, i need to pass those values into my query. But when i try using the session names the page is coming up saying the following:Object reference not set to an instance of an object.
Is there anyway to add something to my page code to see what sessions are actually being created and their values.. maybe im using the wrong variable names.. but the security code is pretty straight forward.. at login, if successful, 2 values are returned and stored in 2 sessions.. i need to use those with my new page.. so trying to figure out why the existing pages work fine with that and my new page does not..
Basically, i'd like to write to the screen the session variables that are being created on the login page.
This works fine - I have now added to the page a LoginStatus as when they arrive they are loggen in. The problem is when the user clicks the Logg off link I get the error on the page below -
Object reference not set to an instance of an object. Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
Source Error:
[Code]....
Is this because the page load is trying to get the logged on user ID
but they have just logged out?
How can I allow the User to logg out without getting the error?
I've been trying to work out this error for a while now and i still dont understand it because i have been following a tutorial online step-by-step but i recieve this error when i log in ?
What i am trying to acheive is when the user logs in then they are able to view their 'profile' such as their name, address etc. The login is validated against a table in a database, ...this is the error i am recieving:
Description: An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.
I have an web application which requires login. When users finish their activities they simply logout. What I need is to clear browser history when user click logout button. This should disable BACK button in browser.
I have a website developed using asp.net/C#. I would like to lock an user account on 5 consecutive login failures within a time period of 30 minutes. I do not want to do this on database side. And I know this is cannot be done by session variables. I also do not want to use cookies for this, as a user can easily disable cookies

What is the best way to use System.DirectoryServices.AccountManagement to lock an Active Directory user object? I'm able to determine if an account is locked using..
UserPrincipal principal = new UserPrincipal(context); bool locked = principal.IsAccountLockedOut();
How do I lock the account? Is there an alternative to doing something like this...
UserPrincipal principal = new UserPrincipal(context); DirectoryEntry entry = (DirectoryEntry)principal.GetUnderlyingObject(); int val = (int)entry.Properties["userAccountControl"].Value;[code]....
I need to display a javascript confirm box after the user successfully logs into the application. If the select 'yes' of the confirm box then I need to navigate them to a different page and if they select 'no' the default.aspx page should be displayed. I am using the login control.
I tried to use ClientScript. RegisterClientScriptBlock on Login1_Authenticate event, it didn't work. I tried the same thing on the Page_Load event of Default.aspx as well as Master Page load event, that also didnt work.
