Architecture :: Showing Real Time Data In An Image?
Jun 8, 2010
I need to build a system which needs to show data on almost near real time basis from a MSMQ data source and this sould be showin in image with a circle as to where the incident occurs.
This is the description given.
The position of the Incident relative to the 123 mark is requested to be represented on a circular concentration diagram .
The algorithm will have to export the location of each incident relative to the 123 mark in polar coordinates (r,θ) and translate this position to the 'master image' coordinate system that will display Incident location.
I have two questions.
1. How can i show the data in an Image and also please point me to any material which might help me with the same.
2. How do i show almost real time data from a MSMQ data source and also how do i architect the same for performance.

I am wondering how is the real-time notification in facebook achieved? What kind of technologies are required?
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?

I'm trying to build an app that simulates "real time" playing, but without Peer to peer. OK so I have a front end built in flash and a back end built in .NET. My concern is that my flash calls a .NET web service every second to check for events in the databasrelated to the specific user in the session. I've seen other scenarios that make posts to the sever every second to have a really precise control... like Bwin casino games.So... Would this have a huge impact on the server? Users bandwich? What the call to the webservice does is check a table in MySQL database to see if there are any events related to the user, and if there are, I get the information and render in flash... Such as new online users, messages, challenges, news ... etc.

Is it possible to edit images using a javascript library and then send the edited image to the server for saving.
Edits will be in real time, means the user can see the edit result in the same time he is editing without the need to refresh the page.
I want a javascript library to do some edits on an image on a webpage 'such as crop, resize, rotate,...' and send send the edited result to the server.

I have a Table (in SQL Server) that is being updated roughly every minute or so with new records being inserted from various sources. The number of records inserted in this duration varies from a few records up to dozens of new records. I am using an update panel to rebind my data every minute to keep the GridView current. Now that I have the data refreshing I am looking for a better solution than reloading the data every minute. how to best keep my GridView up to date? Here is what I would like to accomplish:
1. Load the GridView and refresh the contents every minute. (60 second intervals)
2. When the GridView is refreshed every minute I would like to append only the new records to the existing grid, rather than bringing back the entire result set with each round trip to the database.
3. I would like a visual cue to identify the rows that have been inserted into the GridView. If new rows were to flash/flicker with a background color (yellow) that would be ideal.
Am I even using the correct control for displaying real time data, or are their other options? I essentially am looking to find the preferred method of displaying data that is being updated in real time in a web application. I'm hoping there is a solution involving AJAX but I haven't been able to find much on The Google. I am open to changing anything and everything about my approach -- this is largely a learning exercise. For testing purposes I am currently using LinqDataSource in conjunction with a GridView in an UpdatePanel being refreshed by a Timer control every 60 seconds. Informational: I have also started playing with the [URL] in place of the Timer control. However, for the purposes of this example I would be content to achieve the desired behavior using native controls as I have described them above.

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 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'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).

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?

I am developing a real time tracking system , we are using cisco apis for retrieving the current location and they store this value in a location server(cisco hardware) ie from that server we will get the x and y positions. Using this x and y posituions i need to show the path of the object. i need to continuouly connect this with location server and retrieve the x and y and needto show the path . 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).
