Good question! The problem you have is that you don't know the bounds of your input - you don't know how big number will have to get to generate the required number of primes. However, you can still parellelise chunks of work - something like this: const int N = ( int ) 1e6; static readonly int STEP = Environment.ProcessorCount * ( int ) 1e6; ... var primes = new List<int>( N ); for ( int start = 2 ; primes.Count < N ; start += STEP ) primes.AddRange( Enumerable.Range( start, STEP ) .AsParallel().AsOrdered() .Where( i => IsPrime( i ) ) ); primes = primes.Take( N ).ToList(); You'll have to tune the values of N and STEP for your specific case.

There are C interpreters. Does that make C a scripting language?

Purely in the interests of research, you understand, I viewed one of the related videos. I got a person of the female persuasion stroking her pussy. It was a lovely grey and white one with the longest whiskers and a very loud meoooooooooooow. Is this what counts as porn, or was I really unlucky? Henry Minute Do not read medical books!

I never thought of that! I tried it on a 64 bit Windows 7. I'll check on a 32 bit 7 now.

The 'last' one could have been worse... Imagine that ALL the machines had the 'new last' taking precendence over the system last. Power to all the machines would have to have been cut. Also, I like: 10 Preheat oven to 350 20 Combine all ingredients in a large mixing bowl 30 Mix until smooth

That's great, but I've decided to just write it in C++. I just saw somewhere not to write namespace extentions in managed code.

Change it in the project properties, it can dictate which folder the files are stored in, and you can set where you want the compiler to output the debug and exe files

Thanks everyone, trying it now! EDIT: Works perfectly! THANKS!

I know about reflector. I was asking how to do this in my own programs (I am sure I read somewhere that it is possible)

Ok Thank you very much for bringing this aspect to my attention. It was quite a nice learning experience for me. Thanks ! AliAmjad(MCP) First make it Run THEN make it Run Fast!
