I need to make it completely automatic so anybody can call that url, it will validate that user and do the next step of request and response.

C# - Set Thread As Background Or Not
Jan 2, 2011I 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
Feb 4, 2011In 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?
EDIT:

Getting Website's URL Without HttpContext.Current (running In Background Thread)?
Aug 3, 2010Bit 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, 2010I 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, 2010I 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?
Does The Continuously Running Thread In Background Impact The Website's Performance

C# - Can Execute A Stored Procedure Using Linq In A Background/alternate Thread
Feb 4, 2011In 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?
Configuration :: Unable To Pass Session With Modal Popup Extender And Background Thread
Oct 2, 2010I have a problem with a Model Popup Extender that monitoring a background thread.
I need to give feedback to the user about tasks that happend in the server side.
So searching on internet this give me a solution [URL]
Launch a thread, passing the Session variable, update a flag and a mesage and show the info in the web with a timer.
almost all, is fine, in one server (sadly, close to production) after the task (and thread) is completed, the Session variable is set to null and the user is redirected to a "Session Expired" Page.

I noticed that this is a very slow server and some websites are very slow.
Session is managed with cookies and the timeout is set to 30 min.

View 1 RepliesCall GC.Collect In Custom Thread Pool?
Dec 16, 2010I have created thread pool which have 5 threads. Both of them will start when my application start up. The problem is I created so many objects in thread loop call back function on each threads, and the memory is increase by second when app running, this is thread loop call back function:
void ThreadLoop(){
while(true){
var checkItems = _workItems.Where(w=>w.ActivedTime > 3).ToList();
foreach(var i in checkItems){
_workItems[i.Id].ActivedTime = 0;
_workItems[i.Id].ExecutePostBack();
}
//Recreate new _workItems dictionary
_workItems = _workItems.Where(w=>w.ActivedTime > 0).ToDictionary();
// Sleep thread to free up momory
Thread.Sleep(1000);
// Call Grab collector free memory
GC.Collect();
}
}
I'm confusing that, is calling GC.Collect() on each threads like that good or bad ? Dose it cause bad performence ?
C# - Creating Instances Of A Class Inside A Static PageMethod Thread Safe?
Dec 14, 2010I am using jQuery to call PageMethods. For certain operations, the current user credentials must be validated and for other operations, I need to call other static methods. Here is some sample code:
Sample #1
[WebMethod]
public static void PostComment(string comment)
{
UserAuth auth = new UserAuth();
if (auth.isAuthenticated)
{
//Post comment here...
}
}
Sample #2
[WebMethod]
public static string GetComment(int commentId)
{
commentDto comment = //get comment data from the database...
string friendlyDate = ConvertFriendlyDate(comment.commentDate);
return friendlyDate + " " + comment.text;
}
public static string ConvertFriendlyDate(DateTime commentDate)
{
string friendlyDate = //call static utility method to convert date to friendly format
return friendlyDate;
}
Will I be safe using these kinds of operations? Am I better to drop page methods and just call a separate ASPX page for my AJAX requests?
Thread.Sleep() Blocking NetworkStream.BeginRead() Call Back?
Jul 7, 2010I create a NetworkStream from a TCPClient, I then call BeginRead() followed by Thread.Sleep(60000).
It seems that the BeginRead call back function will only ever occur after Thread.Sleep() has completed. Is this expected behaviour?
What I was expecting was for the call back function to be carried out on a separate thread whenever it was ready and that the Thread.Sleep() on the current thread should have no affect on when/how the call back function runs...
I'm currently creating a VT100 terminal emulator, I wanted to created a method that would allow me to make the emulator sleep until a given string is found in the screen buffer. Initially I was trying to call WaitOne() on the IAsyncResult passed back from BeginRead() if the string was missing (this was to allow more data to pass into the system so that the check could then be carried out again until it was passed), after this failed I tried Thread.Sleep instead of WaitOne() but this blocked my BeginRead call back from firing and I'm now I'm starting to think everything is running from a single thread...
How To Ensure Background Thread Ends When Application Ends?
Aug 12, 2010I have an asp.net 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?

View 3 RepliesDo Background Processing Without Using Windows Service?
Mar 11, 2011I have an web application which needs some calculations and processing on data. This job is a long running job(few hours). Job is initiated by user.
Requirement.
User Clicks on Process Data.
Some functions are called to start data processing.
Data Processing runs for hours.
User is given feedback of percentage completed etc.
Even if user logs off and then again log on he should get this feedback.
The requirement is somewhat similar to Spiceworks. Where it runs in background to detect the devices/computers in network and the user is notified in his page about the progress. But spicework uses windows service. We don't want to us windows service.
Now the question is.
What if user closes the page, will the task still run in background. This task has to be completed fully.If terminated in between output will not have any meaning. How to actually to design this long running process. In ASP.Net environment. Also is there a way to show all/same user who logs in the status of processing.
