Thank you very much Richard
If MS docs had C++ version of this i would have not neded to bother you
I was very confused as i dont do delegates if i can avoid it

Very happy some C++/CLR people still exist

ill mark as solved

Here is the Final working MainForm() showing cross thread update of textBox, Random, and usage of other Member funtions
This is here to help anyone that is as bad at this overcomplicated Parallel coding in C++/CLR (my opinion should be easier)

"Parallel::For" - intellisense still moans about 2 or more overloads of it but who cares anyway, no one :¬)

namespace CppTutorial {

	using namespace System;

		}

	protected:
