How To Ensure Background Thread Ends When Application Ends?

Aug 12, 2010

I have an application with a background thread. The thread starts when the application starts and it is gracefully stopped when the application ends. I am running the website on a shared host. Unfortunately sometimes the application does not trigger the Application_End event when it ends. I would think that the threads would be killed anyway, but that's not the case. I currently have 4 threads running in the background. Three from previous times the application started and 1 from the current application session. How can I ensure that the threads are shutdown when the application ends? Is there a way for the threads to check if the application was reset or had been reset? Or is there a way to check for these rogue threads at application startup and kill them?

C# - Is A New Thread In A Visual Studio Test Project Aborted When The Test Ends

May 15, 2010

i have to do some message exchange with a 3rd party (in a website).When the client posts a page, i start the message exchange. When that doesn't succeed for some reason, i report this to the client by rendering the page with a message.On the background, in a separate thread, i start a process to send abort messages to the 3rd party. I can't do this while the user is waiting for the page to come back, because it might take a few minutes.But in a test project, the test ends when the message to the 3rd party is sent, and after the new thread is started. But it seems that the new thread also ends, when the test is done.

Is that normal behaviour?I do start the thread in a new class with a reference to 2 objects from the class which tries to send the message in the first place, may that be a problem?EDIT: it keeps running when the whole process is started in IIS

AJAX :: Checkbox Placed Next To Slider Ends Up On Next Row

Jan 25, 2010

In a div element, I have a slider (using the Ajax Toolkit slider extender on a textbox). I then want to place a checkbox control right next to the slider - on the same row. However, on the page, the checkbox ends up one row below the slider. It looks like the slider adds a line break after itself. Is this expected? How can I avoid this?

For information, this code is placed in a content section of a page that has a masterpage attached to it. The content section is more than wide enough to contain the slider and the checkbox.

This is the relevant code snippet

C# - Run Command And Make Sure It Ends Before Continuing?

Feb 4, 2010

i am running a command line program from inside my c# code behind page. the command looks like so.

String runMe = baseDir + @"Binffmpeg.exe";
String convertVideo = " -i "" + fullFileName + "" -ab 64 -ar 44100 -b 200 -y -f flv "" + fullFileNameWOextension + ".flv" ";
String makeImages = " -i "" + fullFileName + "" -r 1 -ss 00:00:01 -t 00:00:15 -f image2 -s 120x96 "" + imagesPath + "" + filename.Substring(0, filename.IndexOf(".")) + "_images%05d.jpeg"";
EdgeCastHelper.ExecuteCommandSync(runMe, convertVideo);
EdgeCastHelper.ExecuteCommandSync(runMe, makeImages);

There are some bits missing which are passed in as parameters. Once i have converted the video i upload it to separate file server.

What i would like to know: Is there a way to stop the upload process happening until the exe has run its course, ie fully converted the video.

I have some problems with getting my website to log out the authenticated user automatically when the session ends (the user closes the browser).

This is what I have in my web.config:


When I close the browser, the user is still logged in. How do I make the website forget the user through an option, so the user himself can decide if the website should remember or not?

Security :: User Is Staying Logged In After Session Ends

May 12, 2010

My web application uses forms authentication. One of my users who uses IE8 says that she always stays logged into the website on her computer. This is even after she closes the browser window and restarts the computer. This only happens on her computer, if she switches computers the same thing won't happen.

I'm baffled by this. Is there a setting in IE that could save her login information and automatically sign her in every time she accesses the website? Is there anything else to look into?

Web Forms :: Control Where Text Starts And Ends In Textbox?

May 19, 2010

I am trying to use a custom image for my textbox controls. In Photoshop I used an inner bevel. The only way I can find is to use the CssClass property and then use background-image in css. Problem is the text appears a few pixels to the top right in the box and is not very readable with the shadow. I need to center the text in the textbox. How can I do that?

State Management :: Lose GridView Rows When Session Ends?

Jun 8, 2010

My web application was in .NET framework 1.1 initially. It has a few ASP server grids and some third party controls (Infragistics). I had it migrated to .NET framework 3.0.

Now I've added a few ASP server grids('GridView'). The thing is when the session('InProc') ends after 20 mins, the rows of the newly added grids disappear. However, this is not happening with the grids that were present already pre-migration. I am not using any session variables to initialise or bind the new grids.

This is happening only if the controls are added in the web forms that were involved in the framework migration process. If the control is added in the new web form, then this issue's not occuring.

Also I am not allowed to change the session state to any other. It has to remain 'InProc'. Continuing the session indefinitely is also not an option.

C# - Set Thread As Background Or Not

Jan 2, 2011

I need an explanation regarding some advice I got on this site. I'm doing a newsletter sending app, and I have my mail sent in a seperate thread so the process doesn't slow down the whole web site. A couple of people advised me to set the threads IsBackground property to true. I did this, but was also courious about what this does, so I googled a bit.

As it turns out, setting the IsBackground property to true indicates that "it's okay if the process shuts down while this thread is still running.". Or as microsoft puts it "Any remaining background threads are stopped and do not complete." I don't know if I got this the wrong way but, wouldn't it be better to leave the IsBackground property to false, so that the spawned thread can complete its work regarding the main thread?

How To Optimize The Performance Of A Thread Running In Background

In my website, I am using thread to perform a repetitive process in background. Now the process takes around 30 to 45 seconds to update the database.

Basically the function performs the following:

1) Download the CSV from a website.

2) Parse the CSV and update the database tables.

I want to optimize the performance and decrease the time it takes to 15 seconds.

How can I do this?


Here is the Code:

Getting Website's URL Without HttpContext.Current (running In Background Thread)?

Aug 3, 2010

Bit of a long shot, but is there a way in ASP.NET to dynamically get the website's URL [URL] when there is no HttpContext.Current available.

There is no HttpContext because the code is running in a background thread* (but under the ASP.NET AppDomain). I have a background process that sends emails out every evening, and needs to include the Web address, but I don't want to hard code it because of deployments and testing (it changes from [URL] to[URL] and then to [URL] for the live site).

C# - Finding Information About Sending Emails In A Background Thread?

Jan 21, 2010

I have a thread running in the background that will sleep and pull data from the database when something wakes it up. I am sending the emails using google apps using SmtpClient (code below).

I wanted to know if there is anything i be aware of? I plan to send only one email at a time (a registration or forgot password email). I am a little worried something can happen like an invalid email locking up the thread because i didnt set a timeout or maybe google apps happen to be done and causing the app to blow up. What should i be aware off? I should ask how i should test as well?

Asynchronous HTTP Handler And Using HttpContext In A Background Thread?

Feb 10, 2010

I was reading Walkthrough: Creating an Asynchronous HTTP Handler and noticed they pass the HttpContext from the handler thread and use it in a WaitCallback which runs on a background thread. It makes calls like _context.Response.Write(). Am I correct in assuming that this doesn't violate the fact that HttpContext is not thread safe because the handler thread will not be using it after the async work has started?

Also, Using an HTTPContext across threads has some good information about HttpContext and threads. Is all of HttpContext not thread safe, or just items like Response? Can multiple background threads access the Items property, if only in read mode?

C# - Can Execute A Stored Procedure Using Linq In A Background/alternate Thread

Feb 4, 2011

In my app I am using the open xml sdk to generate a word document and write the file to the response.output stream for the user to download.

At the time that the letter is generated I also need to call a SP via linq data context to update a row in my db.

I think that I need to execute this SP in a seperate thread so that I can simultaneouly write the file to the output. my method looks like this...

protected void btnPrint_Click(object sender, EventArge e)
//call sp to update
//create letter and send to client

Is this feasible or should I avoid seperate threads?
