Technology Used For Running So Many Counters At Same Time
May 18, 2010
I am making a clone of quibids.com in asp.net. This site is in PHP. Can anyone check it and tell me which technology / language they are using behind those so many running counters at the same time? Is that server side counter or client side counter? I have tried ajax counter and ajax update panel in asp.net but it is taking so much time to load all counters and to run those counters. You can see my created website at : [URL]. Can anyone suggest me any good server side counter than ajax counter which can run fast or if I use a simple javascript counter, how can I bind it with database?
I'm trying to add some performance counters to my asp.net website. Now, I know how to increment/decrement some custom counter I make .. but my problem is that if I get my ASP.NET website to create these counters, if they do not exist (eg. i do this check in the global.asax App start method) then add/create them.
But, it doesn't work - access to the registry is denied/forbidden.
I'm assuming this is because the asp.net process is so stripped down (for security) that u can't touch that type of thing. Therefore, i'm wondering if the only other solution is to make a quick console or winform app which does one thing -> add's the perf counters. running this as my normal logged in user would me i have admin rights, so it will work. or is there something else i can do?
I have to show the time taken for a service call in Perfmon from my ASP.Net application. For this, I have added a stopwatch which starts at the service call start and stops at service call stop. Now I have a custom counter which user AverageTimer32 to log the stopwatch values to Perfmon. My question is, how can I show the service names on the Perfmon graph. I am using windows XP (I know windows server perfmon has some fancy stuff).
I read somewhere the website quits running after sometime if no one pings it. I wanted to know is there any way on IIS 6 that will keep the website up all the time(alive) even if no one accesses it
I want to be able to run an ASP.NET application when a file is upload via FTP. I understand how to use the filewatcher class to monitor the directory but I don't know where to put the code so it is always running.
Files will be uploaded once per month for each group of users of the system and the next time the user logs on after the upload I would like the application to reflect the new data. I don't want to check for a new upload when each user logs on because the processing could take a log time.
The uploads are automatic from multiple other computer systems and not done by any user.
The Application is hosted (by GoDaddy) so I don't have full control of the server.
Is there any way to have a process running all the time in the background and if so how? The application is written in VB.net.
We are building a front page/dashboard that queries our database for live statistics. The page has 3 update panels, each update panel has a user control that pulls data for it's box. Lets call the user controls UC_NotStarted, UC_Active and UC_Finished.
We have built the queries that return the data and all of them take a while to run (~7 seconds each). So if we let the first page run with one update panel the image spins for ~21 seconds and display everything. We have broken that code into 3 update panels and set the loading to conditional. When we do this we get one box to load every 7 seconds. That's a step in the right direction but they load sequentially (UC_NotStarted is queried waits 7 seconds and displays, then UC_Active goes for 7 seconds, and finally UC_Finished runs for 7 seconds). We are still at 21 seconds but data is being shown every 7 seconds.
We would like all of the data to be shown in 7 seconds since all of the update panels should be fetching the data at the same time. Instead of using LinqToSQL to pull the data I am now leaning towards web services to get it but not sure if that will work.
My web application currently requires users to upload files, after which I take it for "further processing". This processing is VERY time consuming and can take a while before the control gets back to the user. I would like to run this in the background and not have the user wait until this completes.
I know this question has been asked in this very forum before but I'm not able to understand or I'm not able to proceed in the right direction. My understanding is there are a few ways I can go about this
a) create a BackgroundWorker process in my Global.asax file that will spawn a process and take care of the activity.
b) create a web service that will do the processing for me .. (how?)
I have a webform that has a master page. In the web form I have a dropDownList it has PostBack=True, cause every time I changed the option I concat paratemer (item choosen) at hyperlink's navigate url property, for example I have 2 items:
id text 1 Option1 2 Option2
If the users select Option1 then concat at the url "?option=1" The problem is, that when I choose one option and then click at hyperlink everything goes right, but at the second time I choose an option the browser try to download de page itself aspx. update: even if I click at other hyperlink or link button after choose an option and click the hyperlink, the same thing happens (the browser ask me for download the page aspx)
I have no idea how to avoid this behavior at browser and it happens just at server with the IIS not while I'm testing at VS2008, update: ah I almost forget, if I click "cancel" at the prompt of firefox, then everything goes right again, until the next time I choose other option and click at the hyperlink, then everything goes wrong again...
i am planing to set up a new webproject which has to use a database and a model which can be presented in a browser. I looked at a lot of technologies (JSF, PHP, ..) but i could not find a free and easy framework/technology for me (in the end i prefered asp.net, but this is not free). What can you recommend me for a new webproject from scratch?
I need to create a web application where the layout of the site is entirely programmatically generated - about the only thing that's done declaratively in the markup is the header. Basically, it's one of those AJAX-enabled entire-site-within-a-single-page type of sites where huge chunks of content (structured as modules such as navigation panes for example) are swapped in and out on the fly. From lowest-level to highest-leveled, the options I've considered are:
Classic ASP - Since ASP provides full control over the final output, this would be perfect if not for the lack of separation between logic and presentation and the subsequent lack of code reusability. ASP.NET MVC - REST and MVC routing seem like a poor fit, since there's only 1 actual webpage. Also, interpreting and transforming data and even the UI itself based on business rules (as opposed to direct user input) lies well outside of the deterministic CRUD operations that MVC excels at.
ASP.NET Webforms - Tried something like this using Webforms in the past, but ended up fighting with the ViewState and Postback event model every step of the way. Needless to say, performance was extremely poor and the codebehind was a mess due to the complex logic needed to fully and precisely regenerate each and every single aspect of the page on every single Postback. Silverlight - To be honest, I've never used this. Non-Microsoft technologies - None of the popular ones (PHP, JSP/J2EE, Flash) are entirely suitable either.
Recently we got a project which can be developed either in J2EE or Asp.Net (no restriction from client). Client is asking to give best solution to maintain the project in long run.
Here I don't want to discuss about "Java vs .NET" but need to know which one is preferable to reduce maintenance cost. If I choose any of these technologies, which one will require less development and maintenance cost. Also consider recruiting people like developers, server administrators and software purchase and etc.
If I go to Java, I can choose any Operation System, Web Server, Application Server and database. But for a kind of enterprise applications will there be any low cost when compared to MS technologies?
Simply putting, assume I need to have 100 web servers, 30 database servers. Which one will require less investment?
I was planning to utilize MVP, DDD, TDD, IOC, Dependency Injection, Repository , StructureMap etc but the timeframe is very tight and this can also be achieved in n -tiered architecture:
Technology:
Client Web Portal
ASP.Net /C#/SQL Server
Project Specification:
5 types of customers Template of service Dynamic Data Driven portal Modules can be activated/deactivated through management console Branding and customization Rapid deployment portals of future clients as well Portals willallow for customization Data reporting services: reports and BOBJ Ad hoc Query Value- Add services to the clients portal Each Clients welcome page can be customized by client as well How can I determine which Client is on "Welcome" page without them logging in? Create different URLS for each client base? how? Mobile Application services Localization Demo portal should be built and sent to client for testing rapidly
Database structure:
There will be core database which will be connected to 50-60 client databases depending on the login and other details.
What is the best approach in terms of data layer? since dynamic db connections will have to be implemented?
I have a RFID reader which reads my employee code. Now i want to log the date and time of the chip when it is scanned by the reader (ie) for an attendance system Login time and logoff time. I would like to use asp.net MVC and sql server 2005. how to integrate RFID with an asp.net mvc web application. Where should i start?
My friend and I want to write a Facebook application. We've narrowed down the list of possible technologies to Ruby on Rails and C# with ASP. Here are the pros and cons we've thought of.
Cons:
ASP - proprietary tools like Visual Studio etc. cost (lots of) money. We both don't know ASP (although we're not bad at C#).
RoR - It's scripting so might be harder to maintain. My friend doesn't know RoR at all (but he's a fairly proficient programmer so will probably be able to pick it up quickly).
Pros:
ASP - Facebook has an official SDK for .NET. RoR - I know RoR. It's open source, free and has fast development time.
What says the community? Is there something we haven't thought of?
We have a large code base in MFC and VB. A few applications are in .NET. All these applications interoperate with each other on the user's machine and also connect with Unix servers via sockets. Recently we have started discussing a re-write of our applications and possibility of moving a lot of these desktop applications to web (they would run in intranet). A straight forward way is rewritting them in one of the .NET technologies. But a suggestion about using Google Web tookit has popped up and the argument is that it would help creating applications that would run in a browser on both desktop and mobile devices.
One of the key problem that I see is that GWT is a large abstraction over Javascript. This will require the team to learn GWT, Javascript, IDEs etc as their experience has been primarily Microsoft technologies and not Java. It would be easier for them to learn .NET technologies instead of GWT. I do not have a depth of GWT and its drawback pittfalls and do not know about a parallel Microsoft Technology that I should investigate.
