threads (background worker) question

[csharpula csharp]

Hello,
I got a question regarding the usage of background worker.
How can I run few threads via background worker with different objects
as parameter each time.

I understood that I can't do this:

for (int i = 0; i < inputNum; i++)
{
string param = i.ToString();
bw.RunWorkerAsy nc(param);
}

So,how can I do it by running few threads with one background worker?

Thank you!

This appears to be a perfect case for the ThreadPool, which is a pool of
background threads that you can use without declaring them. In addition, if
there are more tasks than there are threads, it will queue them until a
thread becomes available.

But can't I use background worker for this purpose?

You will need a background worker for all threads. That is, if you want
to run your task in 5 threads you need 5 backgroundworke rs. In your
example you only have one but you'd need 5.

Re: threads (background worker) question

1 worker - 1 thread. You could spawn other threads inside the worker.
You may also want to look at the CCR in the robotics studio. It is not the
api that is so interesting, it is the non-blocking pattern using ports and
handlers.

Re: threads (background worker) question

Buth the question is if can I do something like that using the
background worker:

BackgroundWorke r bw = new BackgroundWorke r();
BackgroundWorke r bw2 = new BackgroundWorke r();

bw.RunWorkerAsy nc(2);
bw2.RunWorkerAs ync(3);


and in this way create as much backgroundworke rs as threads i need or
there is a better way doing it?
Thank u!

Re: threads (background worker) question

Yes you can do that. Create as many as you need (and resource permits). I
thought you asked if you could do multiple threads with 1 BW.
