Separate Service For Processing Long Running Tasks?

Jan 12, 2011

I would like to makea windows service. whenever the user of my ASP.NET application has to do a time-consuming task, the IIS would give the task to the service which will return a token(a temporary name for the task) and in the background the service would do the task. At anytime, the user would see the status of his/her task which would be either pending in queue, processing, or completed. The service would do a fixed number of jobs in parallel, and would keep a queue for the next-incoming tasks. In addition there would be a WinForms application for system administrator that would allow adding special ADMIn tasks such as "Clean orphaned files" or "archive data of inactive users".

Can you point me to something that can jump start me on this as a whole concept - I know I can google for windows services and I am able to do it myself from scratch but time is of the Essence so maybe you know of something that is already there and i can use block to build out of.

Long Running HTTP Process - How To Put In Separate Process

Jul 21, 2010

I know that similar questions have been asked all over the place, but I'm having trouble finding one that relates directly to what I'm after.

I have a website where a user uploads a data file, then that file is transformed and imported into SQL. The file could be up to 50mb in size, and some times this process can take 30 minutes or sometimes even longer.

I realise I need to palm off the actual work to another process, and poll that process on the web page. I'm wondering what the best approach would be though? Being a web developer by trade, I'm finding all this new Windows Service stuff a bit confusing, and I just wanted somewhere to start.


Can I do / should I being doing this with a windows service? if so, how?

Should I use WCF? If this runs under IIS, will I have problems with aspnet_wp.exe recycling and timing out my process?


The data is imported into sql, there's no file distribution taking place.

If there is a failure, it absolutely MUST be reported to the user. The web page will poll every, lets say, 5 seconds, from the time the async task begins, to get the 'status' of the import. Once it's finished another response will tell the page to stop polling for status updates.

queries on final decision

ok, so as I thought, it seems that a windows service is the best idea. So as to HOW to get it to work, it seems the 'put the file there and wait for the service to pick it up' idea is the generally accepted way, is there a way I can start a process run by the service, without it having to constantly be checking a database table / folder? As I said earlier, I don't have any experience with Windows Services - I wondered if I put a public method in the service, can I call it somehow?

Web Forms :: Timeout Error Continues On Long - Running Web App Supposedly Already Configured To Accommodate Long

Jun 16, 2010

I've developed a web application to accept video file uploads and then pass them to a backend service on an external server. The application runs without error on the visual studio debugging webserver, but once on a production iis 6 or 7 server, yields a timeout error at about a consistent amount of time into handling a large upload. Specifically, it errors in the middle of transferring the video file to the external server, once the application has successfully received it from the client. I'm aware of several timeouts to be configured related to the problem, and have done so. The application's web config has been tested with one or both of the following settings

<httpRuntime executionTimeout="9999999" maxRequestLength="2048000" />
<location path="default.aspx"> (the page at issue that's timing out)
<httpRuntime executionTimeout="9999999" maxRequestLength="2048000" />

And within the initialization of the webrequest made to the external server to send the video received from the client browser:

HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(url);
httpWebRequest.ContentType = "multipart/form-data; boundary=" + boundary;
httpWebRequest.Method = "POST";
httpWebRequest.Timeout = System.Threading.Timeout.Infinite;

So with the execution time limits on both the webform as a whole and the connection made to the external server, I'm at a loss for what timeout is left unconfigured, or how to determine such, when I continue to get the following error: Unexpected error executing Brightcove Upload:...........................

DataSource Controls :: Display Results From Two Separate Tables In Two Separate Databases?

Jan 14, 2010

I have access to two seperate databases (mySQL) located on two servers. I need to get the data, link the tables on a key field and display the results in a datagrid. My challenge is that if the search criteria changes for the display it affects rows returned from on table and should thus automatically affect the linked table and resulting data returned.

what the best approach would be to achieving this? So far I have set up a dataset with a dataadapter and table for each connection and then linked the tables in the dataset. The problem that I'm having is getting the linked resultsets to work.

On my form I have the datagrid with two Objectdatasources one for each dataadapter and i believe that's where I'm going wrong...

Use A Regex To Tell If A String Has 10 Digits?

Jan 6, 2010

I need to find a regex that tests that an input string contains exactly 10 numeric characters, while still allowing other characters in the string.

I'll be stripping all of the non-numeric characters in post processing, but I need the regex for client-side validation.

For example, these should all match:

321225 -1234AAAA

But these should not:

123456789 (not enough digits)
12345678901 (too many digits)

Put Comma On Last 2 Digits While Typing In A Textbox

Aug 12, 2012

I don't have a VS in front of me but i would be needing this one next week when i start working again, so I thought I would be prepared.What i want to do is put a comma "," right before the last 2 digits. So I am thinking of ajax masked edit extender but I don't have VS here so i can't do the testings. If it does not have the exact feature i was thinking of some custom javascript-jquery function . Finally a regex to clear out the wrong formats-characters again if masked extender does not work.

My formatting should be like this: 1234567 to 12345,67 , 1 to 1,00 etc. If doable, I would prefer the mask for the masked extender.
