Hello comp.lang.python,
I am attempting to write a threaded program right now in Python
(version 2.3 on Debian unstable) and the current behavior of
KeyboardInterrupt is causing me grief. From the documentation of the
thread module in Python 2.3.3:
"Threads interact strangely with interrupts: the KeyboardInterrupt
exception will be received by an arbitrary thread. (When the signal
module is available, interrupts always go to the main...

Hello,
I'm trying to write a fairly simple network program. The main thread spawns
a thread which creates a listener socket and then calls socket.accept on
it. socket.accept blocks indefinantly. My problem is that when the main
thread determines that it is time to quit, how do I get the spawned thread
to exit? Preferably I'd like the spawned thread to return from
socket.accept when the main thread tells it to and then check a shared...

I've written the code below to try and figure out how threading works.
My assumption is that when starting a new thread it would run at the same
time as the original thread.
Am I wrong?
I've made a simple form with two text labels and a button. When I click the
button, it creates a thread that updates one label, and the main code
updates the other label.
It appears that the created thread doesn't run until the main thread is

I'm experiencing a threading problem that's really perplexing me. I
have a multithreaded application that reads car ECU information that's
sent over the serial port by the ECU and received by the
laptop/program.
I'll try to give a concise synopsis as the program is easily 10k+
lines.
main.cs - contains the application start function. Here's the entire
code (minus misc junk) as it's rather small -

I have a UI that needs a couple of threads to do some significant processing
on a couple of different forms - and while it's at it, update the UI (set
textboxes, fill in listviews). I created a base class for the worker class,
and made up some functions/delegates to handle the invoke stuff for the UI
and that was fine for a prototype. I rewrote this chunk, broke things out
into different classes - but the threading is still the same - and...

I'm creating a WinForms app that will act as a companion (think administrator
functionality) to a Pocket PC app. Generally the WinForms app works under
just the UI thread. But if a Pocket PC connects to the desktop via
ActiveSync then a separate thread is spawned.
In addition to the main desktop app window I also have a Notification form
that appears in the lower right of the screen and provides feedback to the
user about what is...

I am building a class that has a function that I would like to run
asycronously. When the function is complete I would like to notify the
calling thread by raising an event or using a delegate. The handler for the
event (or the delegate callback) should run in the parent thread - not on
the asyncronous thread created while the function ran.
So, basically, I want my parent (form, class, control) to call my class
function - which spawns a...

I'm having a major problem with threads.
I have a main application that dynamically loads plugins. One of the
plugins receives SMS messages in a seperate thread. When an SMS comes in I
need to display an MDI Child form within the Main Application workspace. The
code bombs out when I attempt to assign the MDIParent of the child form to
the Main Form (in the main thread). Some how I need to merge the spawned
thread with the main thread...

Hi,
I have developed a windows forms application that works fine on a single
thread. Part of the requirements of this app is that it monitors the
status of a couple of services.
So I think that the best way to do this is on a separate thread. It will
check every 60 seconds or so to make sure the services are still running.
First of all is this the best way? Second assuming that it is can

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
