Thread is not terminating even after Thread.Abort operation...

23 New Member

In my C# program i am termination thread by thread.Abort when times out occur. But i figured out that even after thread.Abort operation the thread is being alive for the random time. I have given the code snippet for this below.
Expand|Select|Wrap|Line Numbers
  1. private void Delay() 
  2. {
  3.  //Thread waiting for the output stream of the process
  4.  DateTime expireTime = DateTime.Now.AddSeconds(30);
  5.  Thread outputThread = new Thread(new ThreadStart(ReadOutput));
  6.  isApplicationTimedOut = false;
  7.  outputThread.Start();
  8.  while (outputThread.IsAlive) 
  9.  { 
  10.      if(DateTime.Compare(expireTime,  DateTime.Now)<0) 
  11.      {
  12.              outputThread.Abort();
  13.              isApplicationTimedOut = true;
  14.      }
  15.      Application.DoEvents();
  16.  }
  17. }
Is it possible to make thread to stop say after 30 seconds in any case. My basic requirement is thread should get terminated at the 30th Second. It should not run for 31st second.

Could anyone please tell me how can i terminate thread for sure.

What does your ReadOutput function look like? Thread.Abort just throws an exception in the thread function, and it is possible to ignore it on accident.
I would recomend the timing check be done IN the thread and not outside of it.
You are rather defeating the purpose of a thread by sitting in a loop waiting for it to end.

Everywhere in documentation there are recommendations to use threads from thread pooling for relatively short tasks. As I understand, fetching a page or multiple pages (sometimes up to 50 but not tipical) from the Internet and doing some processing on those would be considered to be a big/long task for a thread from a pool. In our app it is possible to break the task into some small ones (thread per fetch and processing thereafter or event...

Hello, I have created a thread that writes data from a memorystream to the harddrive. If the user, during the write decides to cancel the operation, I call Abort on the thread. i.e. Private Sub WriteToDiskButton_Click MyThread= New Threading.Thread(AddressOf WriteToDisk)

I ran into an interesting re-pain delay after calling the Abort() method on a thread, but it only happens the very first time I call it. Every time afterward, there is no delay. I've got a delegate inside the UI that I call to update the progress meter. I use the Suspend() and Abort() methods based on button events. I can watch the progress meter increase just fine when the thread is running. When I select Start, I enable the Cancel...

I saw something interesting when testing my multi-threaded code to make sure that threads were terminating as I expected. When I first bring up my WinForms test application (before I do any Thread.Start), I notice that my process has 4 threads initially. Does anyone know what the other 3 threads in my app's process are for? Also, I posted a question earlier about getting an initial delay after calling Thread.Abort (yes, I know it's not...

Hi I wrote an application server (a remoting sinlgeton), where processes must be stopped in very rare cases, done thru a Thread.Abort(). Occasionally, and only after a Thread.Abort(), this component becomes instabile, throwing a Windows like error (access violation on 0x00000002), not an framework exception. The component and all of its subcomponents are 100% managed code. What could go wrong with Thread.Abort()? Thanks for any hints.

Hi folks, You know, the Thread class has got a method named Abort which according to the msdn: "Raises a ThreadAbortException in the thread on which it is invoked, to begin the process of terminating the thread. Calling this method usually terminates the thread." I've had a long discussion with someone on not to use the mentioned method unless under the most extreme cases. I believe that it's

Because C# has no native SSH class, I am using SharpSSH. Sometimes, for reasons I do not know, a Connect call will totally lock up the thread and never return. I am sure it has something to do with weirdness going on with the server I am talking to. Anyhow, this locked up state happens once in a while (maybe once per day) and I can't figure out how to deal with the locked up thread. If I issue a Thread.Abort() the exception never...
