C# - Real-Time Database Update At Specified Time
Mar 31, 2011
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.

I have a webform that has a button. When the button is clicked, it gathers some records from a database and is supposed to update the UI with each record pulled. But for some reason, the UI only updates when the operation completes. I've posted the markup below. I can post the code if needed.
ASP.NET Code:
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<p>
<asp:Button ID="btnStart" runat="server" Text="Start" Width="94px" /></p>
<table style="width: 99%;">
[Code] .....

Should I User a System.Timer??? Should I record the time and value of the last update, when the person log in I cauculate and update the value??

This is the sqlDateTime overflow problem again. Background. As I'm sure you know dates must be between 1/1/1753 and 12/31/2999. If you have an empty date field, it throws and exception. So I created a function (below) that solve the problem when attempting to update or insert a record with a date field. Works great.
Public Shared Function MakeDateField(ByVal pasDate As String) As Nullable(Of DateTime)
If IsDate(pasDate) Then
Try
If pasDate <= System.DateTime.MinValue Then
Return Nothing
Else
Return CType(pasDate, DateTime)
End If
Catch ex As NullReferenceException
Return Nothing
End Try
Else
Return Nothing
End If
End Function
So I thought about using a time field. I have the field, have the validator in place and then attempted to test the page. It resulted in my least favorite error message "sqlDateTime overflow".
I can think of several workarounds like adding a date or a fixed date to the time field, or converting it to a string. Each of these is problematic.
IS THERE A BETTER WAY TO UPDATE/INSERT TIME FIELDS.

I have a gridview on my page. I have a checkbox in each row of this gridview. For each checkbox in the gridview, I'd like to update my table accordingly, but I don't want them to have to hit a submit button every time they check the checkbox. I want them to check all the boxes they need to and at the end, they should hit one submit button.

I need to add a "real-time" element to my web application. Basically, I need to detect "changes" which are stored in a SQL Server table, and update various parts of the UI when a change has occured. I'm currently doing this by polling. I send an ajax request to the server every 3 seconds asking for any new changes - these are then returned and processed.
It works, but I don't like it - it means that for each browser I'll be issuing these requests frequently, and the server will always be busy processing them. In short, it doesn't scale well. Is there any clever alternative that avoids polling overhead?

I have a set of forms that user must fill, and those forms represent some html output. I want user to be able to see how his input will look like while he filling the fields. So, just wondering if anyone know's a good way or even maybe there is such a thing as plugin or something.

I'm looking for a way to put real time features into my web site. The idea is asynchronous communication between 2 people - like a chat session. If I use the chat example - I'd like the second person to know that the first one has sent a message to him, without refreshing or doing something active on the web page. Polling is not a good idea here - so is there any other solution? the back-end could be ASP.NET or PHP (ASP.NET preferred).

How 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.

I 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?

How this will be possible. Currently we are uising timer and refreshing it with 5 seconds. Is there any other way so that we need to show the path as soon aspossible likle an ant moving along the surfacce.

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 have an asp.net application which uses session for user management. So if the application is restarted users will loose their works. I have some components used by this asp.net application and those components (class libraries in Bin folder) have configurations. I want to save configurations of those components somewhere and change them from back-end (administration panel) and the components use the updated configs but still application should not be restarted (changing web.config will result in application restart).

Another question: I have a asp.net website and a back-end processing software. I want the back-end processing software to comunicate with the website so that the website can dynamically update the page. I am thinking that web service may be the solution. Is this right?
