C# - Looking For .NET Lock Thread Method?
Mar 30, 2010I'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?
C# - Is It Sane To Use Thread.Sleep (int) In .NET Or Should I Use Another Method
Mar 16, 2011I want to introduce a slight wait during some testing functions, to simulate a server call. Is it sane to use Thread.Sleep(int) to introduce the wait or is there a better method to have the server wait?
Note, I'll be pausing long enough for me to visually see a sufficient lag, even tho I don't expect to see such a delay in the actual app. This is for me to visualize the actual delay that could occur.
I plan on running this both in the VS2010 local debugger webserver and in IIS 7. I'm on .NET 3.5
Thread Safety In Parameters Passed To A Static Method
Jan 10, 2011Assuming a static method like below is called from ASP.NET page,can a different thread(b) overwrite the value of s1 after the first line is executed by thread(a)?If so, can assigning parameters to local variables before manipulation solve this?
public static string TestMethod(string s1, string s2, string s3)
{
s1 = s2 + s3;
....
...
return s1;
}
Is there are a simple way to recreate such thread safety related issues?

View 1 RepliesArchitecture :: How Can Thread Update A Variable Shared With The Main Thread
Nov 24, 2010I'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:

What Are The Differences Between Currently Executing .NET Thread And Win32 Thread
Mar 24, 2010I 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.
C# - Lock Thread.sleep Not Working With .NET Thread?
Jun 25, 2010I 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.

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?

View 1 RepliesC# - How To Progress Status From A New Thread
Jan 21, 2010I 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.
How To Invoke A JavaScript Through A Thread
Feb 23, 2011I 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?

View 2 RepliesC# - Read A Value Being Manipulated In Different Thread?
Apr 15, 2010I'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.
Webclient 'thread Is Being Aborted'?
Oct 27, 2010I 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
Thread-safety In .NET With AJAX?
Dec 17, 2010The 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?
