Hi,
Currently I have a thread thats spinning and doing a
Thread.Sleep(so meTime).
I was thinking of changing this to Thread.Sleep(Ti meout.Infinite) ; then
when I have actual data in a collection to process in this thread, I was
going to do a _thread.Interru pt(); Would this be a better approach to
spinning a thread on ?

Normally for using collections one uses the provided .SynRoot property thats
there for that task. If you look at the examples for IEnumerable on
collecitons thats what it uses. collectionObj.S ynRoot
Still, I like to keep locks to a minimum and I dont see a need for a lock
there on an already synchronized object so AutoResetEvents seemed to me to
be more appropriate.
Being a win32 coder , AutoResetEvents makes more sense to me as you point
out.

That really depends on their background. If they're Java programmers
they'll be more familiar with monitors and waiting/notifying them. If
they're Win32 programmers they're probably more familiar with
AutoResetEvents .
Both achieve the
same effect as far as I can see except Monitor takes a lock on the
object and autosetevent does not. Its just an event really. Since the item is
already synchronised I was more concerned about taking another lock on
that object with Monitor.Wait/Pulse.
You don't have to use that particular object though - I usually
advocate using a separate object specifically for locking/waiting etc.
The cost of taking out a lock is pretty small, especially when
uncontested.

What's up with u dude - are you just a part-time ass or what? I
noticed ur stupid post towards someone who asked a question regarding
NGEN in one of the other .NET groups, as well as the rubbish ur

If you have something funny to say, then say it. If you have sod all

I've seen other posts by you where you have actually helped a lot of
people, why do you then insist on posting crap at other times? There's

Yes, SyncRoot is fine for that purpose, but it's often nice to have
separate monitors specifically for thread waiting/notification. It just
makes life a bit easier to understand (IMO) and threading is a very
hard thing to get right to start with.
Still, I like to keep locks to a minimum and I dont see a need for a lock
there on an already synchronized object so AutoResetEvents seemed to me to
be more appropriate.

You should be aware that AutoResetEvents almost certainly use their own
locks internally - I'd be very surprised if they were actually
significantly more efficient than using Monitor.Wait/Pulse. I'm not
saying you shouldn't use them - it's a matter of personal preference,
as I've said, and your last reason makes a lot of sense, but I wouldn't
focus too much on not having many locks. Making sure that you only lock
what you need to is more important, and that usually involves having
*more* locks available, to make each one finer-grained.

NGEN? Can you post this so called thread so I can take a look at it. NGEN in one of the other .NET groups, as well as the rubbish ur
posting to Jon Skeet in this thread.
What gives you the right to jump in here and declare it was rubbish? I have
solid reasons for posting a question like this. May be you should ask before
taking a shot eh?
My reason for posting this
Again I ask: why do you want to know?
it is just soooo discouraging, that's all.
was because I am feeling rather inadequate with my thread knowledge. I was
simply wanting to know if I needed to keep working in the pursuit of
increasing this knowledge or whether I should give it up and do something
else with my life. As he said, it took him a while to get there. I'm not
there yet. That is why it is discouraging to me. I wasn't going to reply to
your bullshit because I didn't think I was being a half ass. You could have
just asked instead of jumping the gun.
And by the way, an individual calling himself Jack Mayoff has been spoofing
my email account (and others by the way) replying to threads in my name. I
haven't caught all his attempts but you may be referring to one of his. I
wont give you the benefit of the doubt either. In short, if you follow my
post, it is rather easy to differentiate between me and a wanna be. But then
again, you couldn't get this last one so go figure.
shall we say an apology is in order? preach, do you think i was being a half
ass?

According to the docs, calling Thread.Sleep(0) causes the thread to be

What happens if I call Thread.Sleep(500)? Do other threads not get a

two?
I have code that runs in a loop like this:

I hope someone can help. I have written a simple form to demonstrate

The form starts a thread, which using delegates updates a label (Every

when I put the GUI thread to sleep (Thread.Sleep), the thread seems to
stall. At first I was expecting dots to still appear, but obviously as
the GUI thread is asleep, they will not. ...

I've got a routine that builds a table using different queries, different SQL
Tables, and adding custom fields.
It takes a while to run (20 - 45 seconds) so I wrote a thread to handle the

Whenever I call the thread, I pass it a structure containing the table and a
few other parameters. The table goes in as a reference, but the other items
are passed normally.

Hi All,
I've been trying to come up with a good way to run a certain process

semaphore flag to false (stopping the thread), my program would have
to wait up to the entire sleep time to break out of the loop.
