How to show progressbar when processing a text file of million lines?
I checked your thread --> [URL]
But what I want is the progressbar should show percentage exactly.
I 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 2 RepliesI'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 doing so many process in a single button click.It is taking more time.So I want to show a progress bar with percentage or status of the process.Is there any way to implement this.
View 2 Repliesi saw that flash website can be develop to show percentage of loading page. when web page is downloading in client machine then a percentage is shown and show much content is downloading in client machine. so i just want to know the same effect can be achieve in asp.net website where we will show the percentage of the page content is downloading in client machine with the help of JQuery when page will be requested by user.

View 2 RepliesHow can i use update progress(in asp.net) with percentage (may be with remaining time span or remaining under process records) while data access from database but that should not be fixed for a fix time period by using like Thread.Sleep(5000). It should show for the actual accessing time period.
View 2 RepliesI'm generating reports on the fly using the great SpreadSheetGear tool. At first things were great because the reports were simple and done in under 1 second. Now I'm at more complex reports and they are taking about 30 seconds up to 1 minute. This isn't a problem, we just throw up an activity image and let the user wait, fine by us.
The problem I've found is when two users come to the site.
User 1 comes to the site
User 1 runs a report that takes 30 seconds.
User 2 comes to the site
User 2 waits until user 1 report is done then the page loads.
The report running for User 1 hangs up the site until it's done. What is going on and how can I fix this?
I want to know how to show the progress bar in WEB while updating the status of progress bar percentage and Status of the application I am trying to built a web application in which I update the scripts from SQLServer to another SQLServer using TransactionScope using Stored Procedures. Here in my app I want to show the progress bar. and its percentage completion of the SP or task and simultaneously updates of the scripts execution.
i.e., Table 1 created, Table2 creation in progress like that or updates etc. Status of 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'm trying to create custom control which displays real-time state (progress bar, or percent value) during time-consuming task (no animated GIF, or static text message).
This scenarion can't be done with standard UpdateProgress control, because it displays only static progress information.
This custom control can be then used as follows:
Aspx page should contain this custom progress control and a button.When user clicks button, page executes postback to the server.Server in button click handler starts performing some time-consuming task. Client installs timer with interval is set to 2000 ms.In client timer event handler should be request to the server for progress refresh.If server receives request from progress control, it checks actual task progress state, and performs client control refresh.When server terminates executing the task, it hides progress control on the client.
How can be this scenarion accomplished? How can I create such custom control?
I am inserting data from gridview to database with checkbox selected item and my requirement is i need to show progress bar in each checked row..i.e if data is inserting the current row should show as inprogress status after that it should say that the process is completed..and so on for all rows how to achieve this..
View 1 RepliesI have an asp.net page that calls a dll that will start a long process that updates product information. As the process is running, I want to provide the user with constant updates on which product that process is on and the status of the products. I've been having trouble getting this to work. I add information to a log text file and I was thinking that I'd redirect to a new page and have that page use Javascript to read from the text file every few seconds. My question is has anyone else tried this and does it work fairly well?
View 3 RepliesI'm trying to create a page that displays a databound gridview to the user showing them the items being processed. Then the page should immediately begin processing. The problem is that the page never shows the gridview (or any other control) until the process is complete. The process is being sent to a WCF service. I've tried setting the page to async and running the wcf in async mode but the content still fails to display.

View 3 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.
