Start a new thread On demand

[Mohammad Hashemian]

Hello,
I'm writing an application that has a main thread. If some special data
arrives from a port, main thread should execute special function in a
new thread rapidly (at most with 500 miliseconds delay).
I used the regular .NET threading system, but in most cases, the second
thread doesn't execute even in 50 seconds.
How can I start a new thread that it'll be executed at once?
thanks.

It doesn't start executing within 50 seconds or it doesn't finish?

How are yous tarting this other thread (Thread.Start() ? queuing the item in
the thread pool?)

Cheers,

I find it hard to believe that the new thread doesn't start in under 50
seconds unless you've hammered the system beyond the point of sanity.

Could you post a short but complete program which demonstrates the
problem?

See http://www.pobox.com/~skeet/csharp/complete.html for details of
what I mean by that.

here is the part of code that starts a new thread:

if(!dataReceptionThread)
dataReceptionThread = gcnew Thread(
gcnew
ParameterizedThreadStart(Machine:ataReception));
dataReceptionThread->Name = "RtdataReceptionThread";
dataReceptionThread->Priority = ThreadPriority::Highest;
Process::Start(Machine::RealTimeExePath);
Machine::baseTime = DateTime::Now;
dataReceptionThread->Start(result);
Thread::CurrentThread->Sleep(500);
if(!dataReceptionThread->IsAlive)
throwgcnew Exception("Thread didn't run yet!");

Note that Thread.Sleep is a static method - it *always* applies to the
current thread, contrary to what the casual reader of

Thread::CurrentThread->Sleep(500);

would anticipate.

Thanks all,
The problem was in another function that was executed in another
thread. That function caused this thread ends early.
By the way, thanks for your attention.
