I hope this helps . I worked in JMX java and I get all the thread IDs by using the getAllThreadIds () method of the interface ThreadMXBean but I need a way to kill the thread of a given ID. for example: , You can try this:

code :

Cross-thread operation not valid: Control 'textBox1' accessed from a thread other than the thread it was created on

To fix the issue you can do The data received in your serialPort1_DataReceived method is coming from another thread context than the UI thread, and that's the reason you see this error.
To remedy this, you will have to use a dispatcher as descibed in the MSDN article:

code :

delegate void SetTextCallback(string text);

private void SetText(string text)
{
  // InvokeRequired required compares the thread ID of the
  // calling thread to the thread ID of the creating thread.
  // If these threads are different, it returns true.
  if (this.textBox1.InvokeRequired)
  { 
    SetTextCallback d = new SetTextCallback(SetText);
    this.Invoke(d, new object[] { text });
  }
  else
  {
    this.textBox1.Text = text;
  }
}

private void serialPort1_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
{
  txt += serialPort1.ReadExisting().ToString();
  SetText(txt.ToString());
}

native c++ thread name does not display in visual studio thread window when debugger is attached after the thread is nam

Hope this helps Thread objects in the Windows OS do not have a name. Naming threads is purely a feature of the debugger. The code to 'set' a thread's name raises an MS_VC_EXCEPTION, that's caught by the debugger, and the information used for the debugging experience. If no debugger is present, the exception filter simply continues execution.
In other words: You cannot have named threads, unless you attach a debugger before calling the SetThreadName function as per How to: Set a Thread Name in Native Code.

I wish this helpful for you I found my solution. to this link. GAE does not work with RxJava beacause It does not respect thred restriction of Google standard environnent. I had to specify how RxJava have to create thread.
Here is my code :

code :

val scheduler : Scheduler = Schedulers.from(ScheduledThreadPoolExecutor(3, ThreadManager.backgroundThreadFactory()))
RxJavaPlugins.setComputationSchedulerHandler { scheduler }

subscriber = Observable.interval(1, TimeUnit.SECONDS)
                    .map { twitter.userOperations().getUserProfile("azeazeaz").followersCount }
                    .subscribe {it -> println(it)}

Calling multiple individual thread asynchronously.But one thread stuck in loop and another thread doesn't execute

hope this fix your issue The problem here is that your client is just a runnable. It needs a backing thread to run its code.
When you call

code :

client2.run();

new Thread(client2).start();

C# Basic Multi-Threading Question: Call Method on Thread A from Thread B (Thread B started from Thread A)

I wish did fix the issue. Typically, this is unnecessary. You can call a method on any object from any thread, and this is a good thing... UI components and some legacy COM components tend to be the only items which must be accessed from a specific thread.
Instead of trying to call a method on a different thread, normally, you'll try to use synchronization (ie: lock(...) and similar) to protect access to the data itself, and make it safe to work with from multiple threads.
