Hi all,
sorry for my beginner question.
How can I change a form property from a thread (I don't think primary
application thread, but the instance of Thread class)? If I do it i get
an exception InvalidOperatio nException - Cross-thread
operation not valid: Control 'lblStatusGame' accessed from a thread
other than the thread it was created on.

You can't - you need to use Control.Invoke or Control.BeginIn voke.

Hi Jakub,
All operations on forms and controls must be done on the main (UI) thread.
If you need to do them from other threads, use the Control.InvokeR equired
and Control.Invoke (see MSDN docs on these for detailed information).

Hello,
I have an application that processes thousands of files each day. The

roughly by a factor of 4). I create up to 12 threads, which then process a
single object off of the stack. I use a loop with a boolean...

Hi -
I am writing a service which will check a process and its threads for
their state ( alive or dead ).
The process has 5 .net managed threads created using thread.start and
each have been assigned a name.
As in .net there is no way we can get the managed threads, I am
thinking of making a win32 call and check their status.

Hi guys,
I would like some advice on thread programming using C#.
I am writing an application that communicates with a panel over
ethernet, collects data and writes it to a file. The way the data is
collected is that we have different schedules (so one set of data is
collected say every second, another set of data might be collected
every 30 seconds, and so on).

Hi,
I like to know how many threads are used by a Threading.Timer object.
When I create a Threading.Timer object calling a short running method
every 5 seconds I expected to have one additional ThreadPool thread.
And that is exactly what MS VIsual Studio shows.
But when I run Processexplorer or Taskmanager I see 2 additional
threads, after a while another 2 additional threads. With the 3 threads
at start time we have totally 7 threads.

All,
I'd appreciate any help. I've got a list of files in a directory, and
I'd like to iterate through that list and process each one. Rather
than do that serially, I was thinking I should start five threads and
process five files at a time.
Is this a good idea? I picked the number five at random... I was
thinking that I might check the number of processors and start a
multiple of that, but then I remembered KISS and it seemed that...

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.
