I have been using threads on and off, but I am always coming across a
situation that baffles me: where is the best place to put a Thread.Abort()
call?
I have a form, when the button event is fired, a thread is created, and it
will continue on its merry way until I force the thread to `die` via the
IDE.
I have in the past used Form_Close and Form_Closing as 2 locations for the
Thread.Abort() call, but in recent times, I have found that it does not
always work, but for the most part it works fine.

Hi Wayne,
The better approach would be to use some other mechanism to end the thread
(event perhaps - signal it when you want the thread to end or something like
that) as Abort has some "features".

I would personally avoid using Thread.Abort at all. Either use
background threads if you want the threads to die when the rest of the
app closes, or signal that you want the other threads to stop in a
timely manner.
See http://www.pobox.com/~skeet/csharp/m...worker.threads
for an example.

LOL - it's nearly as detailed as I know. I'd have to be treading in the
uneasy territory of becoming an expert to put much more into it, at
least in terms of technical details - I could write examples for ages,
of course :)
I'm just hoping I get time to actually finish it some time. I have a
sneaking suspicion that by the time I get round to writing up timers,
I'll have thought of something else which should be in there...

I want to abort a running thread, so I call MyThread.abort() function. My problem is this thread runs "almost" like a while(true) loop and I don't want the Abort() function interrupts the thread at any point in the thread. In fact, I have a section of code needs to be "protected" from being interrupted. How can I make sure Abort() will not land anywhere winthin this block? In other words, the Abort() must wait until this block of code is done...

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...

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.

Hello -
I have a function that calls Thread.Abort() to stop a thread in a
_Closed() Method of a GUI. The thread contains a blocking call on a
TCP socket and that is the easiest way to stop that.
This thread is also outputting strings in a RichTextBox and in some
rare instances I get a System.NullReferenceException when I exit the
GUI. It seems like the _Closed() Method calls Thread.Abort() and then
continues closing down/disposing...

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

Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.

For most users, this new feature is actually very convenient. If you want to control the update process,...
