View 1 RepliesHow do you implement a real-time update like Twitter does ("423 more tweets since you started searching")? I need to refresh my page at least every 10 seconds. I'm using ASP.NET MVC and jquery.
View 4 RepliesI would like to display real time updates on a web page (based on a status field in a database table that is altered by an external process). Based on my research, there are several ways of doing this.
Long Polling (Comet) - This seems to be complex to implement Regular Polling - I can have an AJAX method trigger a database hit every 5seconds to get the current status. But I fear this will have performance issues.
Then I read about using SqlCacheDependency - basically the cache gets invalidated based on a field in the table. I am assuming I can use the event trigerred when the cache is invalidated to show the new update to the user?
I have seen several websites that show you a real time update of what's going on in the database. An example could be. A stock ticker website that shows stock prices in real time Showing data like "What other users are searching for currently.." I'd assume this would involve some kind of polling mechanism that queries the database every few seconds and renders it on a web page. But the thought scares me when I think about it from the performance standpoint.
In an application I am working on, I need to display the real time status of an operation that a user has submitted. Users wait for the process to be completed. As and when an operation is completed, the status is updated by another process (could be a windows service). Should I query the database every second to get the updated status?
I would like to create a progress bar with real time updates on the different method calls that happen on a button click in asp.net 1.1. I have seen some examples but nothing that provides updates on the progress bar while the server side operation executes.

View 1 RepliesI want to develop a utility where user will insert new Records and also the same application should work if user is not connected with internet.When user wants to submit records only that time he required to connect internet.
We have created one sample application using excel where we use Dropdown, Textbox, Label.User will download excel file from website and filled up details. When user wants to submit all details only that time internet is required. Application will insert value from excel file to server using WebServices when user click on submit button.
Above is working file but it's increasing our work because we are creating website and also Excel project (Almost double work). I want something where we can utilize the code for online and offline application.
I have below code to display "list of all the online users" inside listBox using Membership function.
Code:

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

Given a Database that has a table Called [Bid Transactions], which contains records of all available auctions that are currently running on an ASP.net website .. something similar to Ebay.com, when the deadline of the auction passed, I should close that auction, Send a notification message to both the item owner and the bidding winner to inform them.
how should I keep track of all open auctions? how could I monitor all their ending time and update the Auction status to be "Closed" on Real-time basis? ..
(1) Using SQL jobs ? .. that should reduce system performance .. shouldn't it ?
(2) A back-end service that is running on the server and uses Threading ? .. I have no clear background about that solution.

View 4 RepliesI was wondering how I would develop a page that allowed a user to type something into a text box that would show up in a label as they typed. I was looking for this online and found a few options but none of them worked. They included JavaScript, Ajax, and using the text box is onTextChanged command. For an example I need something similar to VistaPrint.
