I have a button clicking which a storedproc runs for long time in buttons onclick event.
I have a grid which will show log table data which gets updated by the storedproc.
I want to refresh the grid to show the updated log while the storedproc runs.
Is it possible?
Project
I'm running a single page (default.aspx) web site in Visual Studio 2010. I have a few other projects in the solution, but they're all taken out of the build queue at the moment. I'm using Visual Studio Development Server as the web server (I haven't tried IIS yet). I'm using the HTML5 Boilerplate from [URL] I'm testing in Chrome and IE8
Problem
Visual Studio 2010 is outputting "Debug" information to the Output window every time I refresh my browser. Whilst this isn't a problem in itself, it seems to be extremely slow in doing so... it takes around 4 seconds to show the page in full from initial refresh.
I've noticed that the "Script Documents" folder appears in my solution view, and some files (notably JS files) seem to take a while to show up. I've tried removing all the JS and CSS file references from my page, but it still does it.
So, to troubleshoot I've created an index.aspx page with no content apart from the generic ASP.Net template code, set this as the start page, but it still takes just as long to load up as the other page.
As a last resort, I've created a new project and tried it with no changes to the default page - still the same, takes a few seconds to finish loading in either browser.
The strange thing is that this happens even when I stop debugging in Visual Studio and browse directly to the URL on the ASP.NET Development server.

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
<system.web>
<httpRuntime executionTimeout="9999999" maxRequestLength="2048000" />
</system.web>
and
<configuration>
<location path="default.aspx"> (the page at issue that's timing out)
<system.web>
<httpRuntime executionTimeout="9999999" maxRequestLength="2048000" />
</system.web>
</location>
</configuration>
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:...........................
I am making some application in asp.net 1.1 in that I am displaying data in datagrid from database. In data grid first column is of check box and radio button and in the last column we have text box now thing is that when i click on check box crosponding textbox we fill some figure and at the end we press calculate button to get total. After getting total we have to press continue button to go next step
But suppose if some body remove that check the we should press calculate button or chnage some figure in the text box then we should press calculate button again to recalculate. for that i kept autopost back on check box oncheckedchanged event and text box ontextchanged event and hide continue button so user will click calcutae button abd then continue button will re-apper
Problem it that it taking too much refresh and taking long time. So was lloking for some ajax method to use in my application.
I am executing a long-running Oracle stored procedure from .NET. The procedure takes about three hours to run. Ideally, the user should be able to kick off the procedure, close the browser, and come back later to check the results.
The problem is that the connection to the Oracle procedure is lost after exactly an hour. As you would expect, the Oracle procedre runs to completion if it is executed from SQL Plus. Strangely enough, it will also run to completion if I run in debug mode on my local machine (I start two threads, one of which executes the procedure. I set a breakpoint on the second thread).
Here is my connection string:
data source= (DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=serverx)(PORT=1521)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=TestSID)))
Some relevant sections from web.config:
<sessionState mode="InProc" cookieless="false" timeout="3000" stateNetworkTimeout="72000"/>
<httpRuntime executionTimeout="18000" maxRequestLength="2097151" />
Any thoughts as to why the connection is being lost in exactly an hour, and what I can do to maintain the connection until the procedure finishes?
I have a problem when I try to pass in paramaters for a report in my report viewer. I have set up the ObjectDataSource and set the paramaters for 3 text boxes that are on the page. The only way I have found to set the paramaters for the report is the user must fill in the paramaters and hit the refresh button on the Report Viewer toolbar ,but I would like to have the user click a asp.net button insted. Is there anyway to call the refresh method from codebehind?
View 1 RepliesI am working on a ASP.NET 2.0 application. It is hosted on IIS 6 on Windows 2003 server.
Few pages have jpeg images (around 50 images and 50 KB each). It takes long time to load the page for the first time. But when i open the same page for the second or third time it is faster.
why does a web page take long time to load for the first time?
Is it cached somewhere when it loads for the first time? Do we have any control over it?
I have developed an application in asp.net with crystal report. It has more than 30 pages in the project. Now I want to improve the performance of the application.1. What I need is , I want to know each and every page loading time and where actually it take long time to load while requesting the page.There are so many tools available. But am not able to follow as where actually the problem is and how to solve.
View 6 RepliesIn an asp.net web form, I keep getting a connection reset error message. The page is doing a some long running processing (about 2-5 minutes).
I have no problem when the web request comes from the same machine as the web server. But when the request originates across the network, I get a connection reset error about 1:30 or 2 minutes into waiting for a response.
I have set the in web.config for this application and put the application it's own application pool.
What else can I try?
Edit
The purpose of this page is to accept input from the user, calculate something, and send the result back to them. The long running calculation isn't something I can offload until a later time.
My application is a asp.net 3.5 running on iis 6 (windows 2003)
This application is serving 1000's of users daily (100-500 users online).
I want to send an email newsletter to customers weekly.
Around 200,000 emails every time.
This is the code im using:
ThreadPool.QueueUserWorkItem(new WaitCallback(AsyncProcessMailerQueue), null);
private static void AsyncProcessMailerQueue(object data)[code]....
When testing this locally (on my dev machine) i see the application is working alot slower.
Is there a better way to write this code? Should i use ThreadPool.QueueUserWorkItem or create a new thread using Thread t = new Thread(new ThreadStart(DoWork)); ? Will it be better to create a totally seperate application for the purpose of sending the newsletters. will that help if ill run this application on the same machine?
i've seen other posts here talking about ThreadPool vs Thread but its seem no one is sure which is better.
When an ASPX page needs to make a call to a potentially long-running operation (lengthy DB query, call to a remote webservice, etc.), I use RegisterAsyncTask, so the IIS worker thread is returned to the pool, rather than being tied up for the duration of the long-running operation. However ASMX webservices don't have a RegisterAsyncTask function. When an ASMX webservice needs to call a potentially long-running operation, how can I implement the same behavior as RegisterAsyncTask? Note: the ASMX webservice is implemented as a script-service: returning json to a direct jQuery/ajax call. Therefore, I cannot use the "BeginXXX" approach described by MSDN, since that implements the asynchronous behavior within the generated client-stub (which isn't used when calling the webservice directly via ajax). EDIT: Adding source code: implemented the BeginXXX/EndXXX approach listed in John's answer. The synchronous "Parrot" function works fine. But the asynchronous "SlowParrot" function gives an internal server error: "Unknown web method SlowParrot"

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.
I'm looking for ways to improve a web page that initiates a long-running (>2 minutes) server-side task. The current version of the page just clocks for the full duration of the task, which can be very frustrating to the user.
I already have a few ideas about how I could improve the user's experience, but they all would involve the use of AJAX to some extent. Because of previous experiences that I've had on this project, I know that not all users have JavaScript enabled or available.
Assuming that the server-side process has already been optimized as much as possible, what else could I do to improve the experience of all users as much as possible?
Note:- i don't want to use updateprogress etc. control of ajax
on button click, long task(e.g thread) runs in my webpage for about 4-5 minutes.I want to show status to user either by a processing image through javascript(image must be shown in a certain part of page other part of page will remain intact) or an exact status of process if possible. i have tried a lot but all in vein.
I have a long-running WCF service that I need to call, but I would like to do is to open modal window (modal popup extender) that simply shows progress and stops the user from interacting on the page until the service returns. What I was trying to do was the following:
1. Click button to activate the process which calls a method in my code-behind.
2. This method opens my modal panel with some pretty animation.
3. I call my WCF service asychronously so that the UI will refresh.
4. Service ends which calls my delegate I setup.
5. My delegate method would then refresh the page with results, and dismiss the model popup.
I am using SOA architecture, any one guide me what major and minor thing we need to take in long running.
View 3 RepliesI have a report that takes a couple of minutes to generate.What I am trying to do is display a progress indicatior onscreen (progress bar or spinning circle) while this is running.I was thinking of using javascript to display the progress indicator but am not sure how to get started on this. am using ASP.NET 2008, C#.

View 1 RepliesI have NHibernate sessions cached in the ASP.NET session.
I came across a situation where a user edited an object so it's in their first level cache in the ISession. Another user then edited the same object.
At this point User1 still sees their original version of their edits where as User2 sees the correct state of the object?
What is the correct way to handle this without manually calling session.Refresh(myObj) explicitly for every single object all the time?
I also have a 2nd level cache enabled. For NHibernate Long Session should I just disable the first level cache entirely?
Edit: Adding some more terminology to what I'm looking to achieve from 10.4.1. Long session with automatic versioning the end of this section concludes with
As the ISession is also the (mandatory) first-level cache and contains all loaded objects, we can propably use this strategy only for a few request/response cycles. This is indeed recommended, as the ISession will soon also have stale data.
I'm not sure what kind of documentation this is for it to include both probably and then immediately say the session will have stale data (which is what I'm seeing).
we have a sql server 2005...that has 70-80 databases and hundreds of tables....
It is supposed to refresh every night.... refresh is done by other vendor(3rd party).... we dont know what method(technology) they use to refresh the databases....
My question is .....
Is there a good way to know when the last refresh has happend...can we determine it from sys tables.....
the sql server is installed in window server 2003 box.... we have access to the box as well as the sql server.....
I've been having a difficult time with this. I have an asp.net page. The user hits the "Run" button and I have code IN AN ASSEMBLY, not in the APP_CODE folder that is called and runs a long process that moves product info from a file into the database. While the user waits, I would like them to see status updates like what product the import process in on and status info. I'm assuming I'd break off into another thread and use Ajax but I have no idea how to do this.
View 4 RepliesI have a long poll HTTP request using ASP.NET 4, MVC 2 and AsyncController. If a user closes their browser and kills the HTTP connection without the request completing, I'd like to know about it and completely clean up after them. If I don't, the open and incomplete requests just sit there and eventually IIS stops accepting new requests.
You can simulate my long running HTTP request by making a normal ASP.NET application with a page that has a Thread.Sleep. Even if you close the browser, the request carries on as if it hasn't.
There is a property called Response.IsClientConnected that gets switched to false if the client disconnects, and I can poll this to achieve the desired effect but it's not very clean and I'd like to avoid polling. Is there a way of getting notified when this happens rather than having to poll this property?
I need to invoke a long running task from an ASP.NET page, and allow the user to view the tasks progress as it executes.
In my current case I want to import data from a series of data files into a database, but this involves a fair amount of processing. I would like the user to see how far through the files the task is, and any problems encountered along the way.
Due to limited processing resources I would like to queue the requests for this service.
I have recently looked at Windows Workflow and wondered if it might offer a solution?
I am thinking of a solution that might look like:
ASP.NET AJAX page -> WCF Service -> MSMQ -> Workflow Service *or* Windows Service
Wondering if there is a performance difference between letting a long running process hang in asp.net vs running the process via a windows service. I have done this once before and the windows service was much quicker and didnt bog down my system, whereas the asp.net request seemed to wreak havoc.
View 1 RepliesI have a site that calls a long running stored procedure that eventually times out the UI. The procedure simply runs some logic in the database, and kicks of a secondary process. No data is ever returned to the UI, so I don't need the UI to wait for anything.Is there a way to call the stored procedure from the UI and move on without having the UI having to wait for the store procedure to complete?
