Get A List Of Online Users In Mvc?

Jan 23, 2011

I have a page in my application which always shows updated list of online users. Now, to keep the list-which is stored in application object- updated, i do the below steps

add user to list when login remove user on log off Then to handle browser close/navigate away situations, I have a timestamp along with the username in the collectionAn ajax call every 90 seconds updates the timestamp.

The problem:

I need something to clean this list every 120 seconds to remove entries with old timestamps.

How do I do this within my web application? ie Call a function every 2 mins.

PS: I thought of calling a webservice every 2 mins using a scheduler , but the hosting environment do not allow any scheduling.

Checking For Online Users On A Game?

Jan 20, 2011

I need a reliable way of checking if a user is logged into a web based game. This is the scenario:

I have a game on the front end built in Flash with Actionscript 3, that calls a web Service in .NET. So in some way I'd like to create a reliable way of getting a list of users that are logged into the game. I would need to create a Timer in Actionscript that calls a method in the Web Service every certain amount of time, but I'm not sure which is the best way to do it on the server side.

I remember in the old days with classic asp I'd use global.asa and it was not reliable at all. Also, checking a database with a boolean, would always depend on the user clicking on "logout". So i guess there needs to be some kind of asyncronous coding in there somehow.

Count - Get Number Of Concurrent Users Online?

May 3, 2010

I would like to know the number of users logged into my ASP.NET 2.0 application.

Points to be considered:

1) Simplest way would be to use Application or Cache object to have the counts on Session start or end. However this would fail if there is a worker process recycle. Wouldn't it?

2) Should't make a difference whether the session is inproc/state server managed/ or SQL server managed.

3) Should preferably be seamless to a web-farm architecture.

C# - Counting Online Number Of Users Of A Web Application?

Jul 18, 2010

I am using ASP.Net + .Net 3.5 + VSTS 2008 + IIS 7.0 + C# to develop a web application. I want to count how many users are online. This is my current implementation,when Session_Start is called, I will increase # of users online by 1;when Session_End is called, I will descrease # of users online by 1.Two quesitons,A Is that implementaiton correct?B. Another question is, I think this method can not track # of users of real time, since when user closes the browser, Session_End will not be called immediately (Session_End will be deferred to be called). Correct?

VS 2008 - How To Know Which Users Are Online (Login Security)

Aug 5, 2011

I've got a website project and I use my own login security and save the user and other info in session variables. Is there any way to know when they are online and offline by their user name I have in a session variable? Or do I need to use another method such as the asp.net user security?

I do know with the asp.net security I can check if a user is authenticated.

Web Forms :: Display Online Users Except Current Logged In User In Membership

May 7, 2015

I have below code to display "list of all the online users" inside listBox using Membership function.

Code:

protected void Page_Load(object sender, EventArgs e) {
if (!IsPostBack) {
MembershipUserCollection allUser = Membership.GetAllUsers(); // to get all the users
List<MembershipUser> onlineUsers = new List<MembershipUser>(); //creating list of online users
foreach (MembershipUser user in allUser)

[Code] ....

I want to remove that user from the list of online users, who himself has logged in. Example: if I had logged-in with UserName: Admin, then this Admin should not show to me in the list of "online users"

Tried below Code but not working:

protected void Page_Load(object sender, EventArgs e) {
if (!IsPostBack) {
MembershipUserCollection allUser = Membership.GetAllUsers(); // to get all the users
List<MembershipUser> onlineUsers = new List<MembershipUser>(); //creating list of online users
MembershipUser m_user = Membership.GetUser(); //to get self logged-in user

[Code] ....

C# - Best Pratice: How To Implement A List Similar To Stackoverflow's Users List

Apr 7, 2010

Technologies involved:

ASP.NET Web-forms
Javascript (jQuery for instance)

Case,To make it clearer let's give the Stackoverflow Users list as an example. This list can be manipulated at client-side. I can search, page and so forth. So obviously we would need to call jQuery.ajax to retrieve the HTML of each page given a search. Alright. Now this leaves me with the first question:

What is the best way to render the response for the jQuery.ajax at server-side? I can't use templates I suppose, so the most obvious solution I think is to create the HTML tags as server-controls and render them as the result of an ASHX request? Nice. That solved we have yet another problem:

When the user first enters the Authors List the first list page should already come from the server completely rendered alright? Of course we could render the first page as well as an ajax call but I don't think it's better. This time I CAN use templates to render the list but this template couldn't be reused in case 1. What do I do?

Now the final question: Now we have 2 rendering strategies: 1) Client and 2) Server. How do I reuse code for the 2 renderings?
