The following code does not exit the application. How can I exit the application and make sure all the running threads are closed?

foreach (Form form in Application.OpenForms)
{
    form.Close();
}
Application.Exit();

You don't show the use of any threads in your code, but let's suppose you do have threads in it. To close all your threads you should set all of them to background threads before you start them, then they will be closed automatically when the application exits, e.g.:

Thread myThread = new Thread(...);
myThread.IsBackground = true; // <-- Set your thread to background
myThread.Start(...);

Killing threads in Java, A thread is automatically destroyed when the run() method has completed. But it might be Whenever we want to stop a thread, the 'exit' variable will be set to true. filter_none. edit the main Thread. Note: The output may vary every time. 4 Answers4. When you start a thread, it begins executing a function you give it (if you're extending threading.Thread, the function will be run () ). To end the thread, just return from that function. According to this, you can also call thread.exit (), which will throw an exception that will end the thread silently.

You can try the following code:

Environment.Exit(Environment.ExitCode);

Python, Raising exceptions in a python thread; Set/Reset stop flag; Using traces to kill Thread.__init__( self ). self .name = name. def run( self ):. # target function of the Suppose in the above code, we want to kill all the processes after 0.03s have  If you want the app to exit when the main thread has finished, you can just make the new thread a background thread: Thread t = new Thread(Main.MyThread); t.IsBackground = true; t.Start(); Basically the process will exit when all the foreground threads have exited.

I went through a similar issue in my software, but unfortunately just making the threads to work in background didn't solve the issue. In fact while the thread brings back data (the main software is data driven) and if I close the application, it results to Windows Error, giving rise to a debugging message.

So what actually worked for me:

Step 1: Made all threads run in background such as

Thread aThread = new Thread(MethodName);
aThread.IsBackground = true; //<-- Set the thread to work in background
aThread.Start();

Step 2: In the closing action of the form/application call the Environment.Exit method, such as

Environment.Exit(Environment.ExitCode);

This kept the memory managed perfectly, with no memory leak.

Hope this helps.

How to Kill a Java Thread, Learn how to properly stop a Thread in Java. private final AtomicBoolean running = new AtomicBoolean( false );. private int interval;. Well, you could call Application.Exit() but that won't be of much help. The bottom line is that you have to gracefully close all of the threads yourself if you want to do things properly.

This should work for all threads you opened.

protected override void OnExiting(Object sender, EventArgs args)
{
    base.OnExiting(sender, args);
    Environment.Exit(Environment.ExitCode);
}

[Solved] Kill a thread properly in c# win. form, When set to true , will cause all threads to abort (the process will exit(0) ) if an exception is raised in Does not block new threads from being created and run. Calling exit while other threads are still running will likely result in a crash. No C++ cleanup will be done. as @πάνταῥεῖ says you need to join all other threads before shutting down. – sjdowling Nov 7 '14 at 17:14

This got the job done for me:

Instead of using:

Application.Exit() 

which leaves other threads open, try using:

Environment.Exit(Environment.ExitCode);

priority (Thread), Invoking Thread.stop() results in the release of all locks a thread has The thread's run() method polls the done flag and terminates when it is  std::thread::native_handle() only can get the thread’s valid native handle type before calling join() or detach(). After that, native_handle() returns 0 - pthread_cancel() will coredump. To effectively call native thread termination function(e.g. pthread_cancel) , you need to save the native handle before calling std::thread::join() or std::thread::detach() .

THI05-J. Do not use Thread.stop() to terminate threads, Because all threads share the same data space, a thread must perform cleanup Similarly, a thread can exit at any time by calling the pthread_exit subroutine. call returns, the request has been registered, but the thread may still be running. //when i want to terminal this thread ,just post a message to thread PostThreadMessage(FThrID,WM_QUIT,0,0); //where FThrId is the ID of the Thread How and we do in c#? How and we post a messge to a thread so that the threadproc can do a certain thing ? You'll need to be running a message pump, and then use something like Control.BeginInvoke.

Exiting a thread, call process::exit(1) on the main thread - hangs, process marked from some reason all the actors seems to exit (i print the last line), but one of Yeah, that's almost certainly it because Docker doesn't run a pid1 by default. We've added an interrupt() method that sets our running flag to false and calls the worker thread's interrupt() method. If the thread is sleeping when this is called, sleep() will exit with an InterruptedException, as would any other blocking call. This returns the thread to the loop, and it will exit since running is false.

How to properly exit multithreaded app? - help, The thread exit code is set.The thread When a thread terminates, its thread object is not freed until all open handles to the thread are closed. Notice that, thread t1 stays alive and prevents the main program to exit via sys.exit(). In Python, any alive non-daemon thread blocks the main program to exit. Whereas, daemon threads themselves are killed as soon as the main program exits. In other words, as soon as the main program exits, all the daemon threads are killed.
