I'm new to threading and have used it successfully, but limited. I can spawn a thread and have the main thread reference variables in the spawned thread, but I don't know how to allow the spawned thread to reference (and update) variables in the main thread.
Any example threading code I've seen on the web appears to be WAY more complicated than what I do, so I am unable to understand or integrate into my code.
Here is a quick example of how I use threading:

I am reading the Asp.net security documentation on msdn.I come across these tow terms and get really confused.
# WindowsIdentity = WindowsIdentity.GetCurrent()
which returns the identity of the security context of the currently executing Win32 thread.
# Thread = Thread.CurrentPrincipal
which returns the principal of the currently executing .NET thread which rides on top of the Win32 thread.

I have a password page and when someone enters an incorrect password I want to simply foil a brute force attack by having
bool isGoodPassword = (password == expected_password);
lock (this)
{
if (!isGoodPassword)
Thread.Sleep(2000);
}
I would expect that this would allow all correct passwords without stalling, but if one user enters a bad password another successful password from a different user would also be blocked. However, the lock doesn't seem to lock across ASP.NET threads.

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?

So basically here I am trying to wait for my server to connect to my website signaling it that its done and so the page needs to be refreshed(cause sql was updated). Thing is when I try to use the response/request in the thread it simply doesn't want to work.

Code:

Errors I am getting are:
1. If I have the headers clear thing there it gives requires integrated IIS pipes or something like that.
2.If I don't have the clear headers it says the headers were already sent.

I am executing time consuming task in a new thread. ParameterizedThreadStart pts = new ParameterizedThreadStart(WorkingFoo); Thread thread = new Thread(pts);
The WorkingFoo executing the task and keeps track of the progress steps (it can return the total number of "steps" and the current step).
I want to display this information in a progress bar (simple div or ajax control, I don't mind).
I don't want, ofcourse, visually refresh the page that will display the progress. Also I want to reduce as much as possible the number of postbacks. So how do I do that? How to show the current progress from new thread on the web page? Also the page that shows the progress can be closed and re-opned and still get the current status.

I have a thread that runs querying a DB and returning some values. If this values satisfyes a condition, I want to raise a message box (javascript alert) for the client side.
In my system, users can post some tasks in DB, and the thread is going to constantly query the database to check if user has things to do. If user has, the system must alert him through a message box.
I've done javascripts invokings with ClientScript.RegisterStartupScript, and Attributes.Add for buttons. But now I want to call the javascript functions (wich will alert the user that he has things to do) from the midle of a sub (that is executed in a thread), without a submit, load or click event. How can I do it?

I'm developing an ASP.NET forms webapplication using C#. I have a method which creates a new Order for a customer. It looks similar to this;
private string CreateOrder(string userName) {
// Fetch current order
Order order = FetchOrder(userName);[code]....
The problem here is, it is possible that 1 customer in two requests (threads) could cause this method to be called twice while another thread is also inside this method. This can cause two orders to be created.
How can I properly lock this method, so it can only be executed by one thread at a time per customer?
I tried;
Mutex mutex = null;
private string CreateOrder(string userName) {
if (mutex == null) { [code]....
This works, but on some occasions it hangs on WaitOne and I don't know why. Is there an error, or should I use another method to lock?

I have a WCF service method that's running in a worker thread I spin from another method. I need to map a relative service app path ("~/Templates/a.template") to the physical path ("D:WebTemplatesa.template"), but I can't use HttpContext.Current.Server.MapPath because HttpContext.Current is null in a worker thread. How else can I reach MapPath method?

I'm trying to read a static property from a static class, which is being modified from a different thread.
Basically I have this static class:
public static class Progress{
public static int currentProgress{get; set;}
}
and this thread manipulating the currentProgress:
private void Job(){
for(int i = 0; i<100; i++){
Progress.currentProgress = i;
Thread.Sleep(1000);
}
}
While this is running, I have a HttpHandler trying to access this progress (every few seconds), like so:
public void ProcessRequest(HttpContext context) {
context.Response.Write(Progress.currentProgress.toString());
context.Response.End();
}
But the currentProgress is set to it's initialvalue here, while the workThread is working, and only when done, is the currentProgress updated.

I run a loop that downloads a lot of smal files from another website
try
Loopstarts
result = runData()
loop ends
catch ex1 as exception
End try
private function runData() as string
Dim wc as new WebClient
Dim str as string
try
str = wc.downloadstring(filePath)
catch ex2 as exception
return "Nothing"
end try
wc.dispose()
finally
return str
end function
THE Problem is if the file is not found in the RunData function I get 'Thread being aborted' error which stops the not only the function RunData() but also the loop is running in, so I get an error in ex2 as well as ex1. But I want the error to be captured in ex1 and stop, and not effect the loop.
I have read that you need to use Response.End to close the thread or not to capture the 'threadbeingaborted' expception.
BUT how do you do the response.end with a webclient??? (IN vb.net , asp.net 2.0 version

The question is, is it possible that requests for the same session are executed from multiple threads? Are methods in ASP.NET reentrant? Especially we are using AJAX which means that asychronous requests are taking place.
Would this mean to place locks around operations on objects placed inside the session?I know that locks are essential when handling static and application wide variables, but the question is is the same true for session objects?

I have a page which has populated a database with a set of information that needs to be processed. This could take a considerable amount of time and I want it to run in the background, mean while I will have my web app display a page with an intermittent meta refresh showing me progress of the records in the DB being processed.
What I think I need to do is start an executable, in a different thread running in the backgound on the server which will run until it is complete, without interfering with other web activity.
Can this be done? Do I start it in a different thread? How can I start the exe in that thread and just leave it to do its work?

Can someone explain me what is is the relationship between App Domain and thread? msdn says "threads are free to cross application domain boundaries; a new thread is not created for each application domain." suppose there is one thread t inside Appdomain a1 .there is an another App domain a2 .thread t can cross to a2 from a1 means it can access a2 memory area If thread can cross the app domain boundaries share the memory space then how application domain isolation is still there?

I have a web service that creates a thread to process some data in the background. I've seen a "System.Threading.ThreadAbortException: Thread was being aborted" message in one of my logs where the thread was killed. I am currently under the assumption that the thread will run as long as it takes to execute the tasks that it's working on, however after googling the exeception I've seen several posts making mention of increasing the ExecutionTimeOut property of the application in the web.config file. My question is: What is the maximum execution time of a thread executed in ASP.NET? Is this timeout unlimited or still bound by the ExecutionTimeOut property of the application?
