Class hierachy and methods

[Tom Machado]

Hello,

I am working on a project and have become a little confused on how to
call methods from another class. Before I explain, here is an example:
class 0
{
main()
{
class 1 = new class1();
}
}

class 1
{
class1()
{
/*
now I want to call a method from class 0 (i.e.
class0.getVariable()) do I need to make a new instance or what since
this class already being called by class 0?
*/
}

}
Any idea? Also, class0 is a windows form and class1 is not, so calling
it again doesnt really make sense to me...

Thank you!

Tom

The second class need a reference to the first class.

If the first class A do:

B o = new B(this);

and the second class B looks like:

public class B
{
private A a;
public B(A a)
{
this.a = a;
}
...
}

then other metods in B can call:

a.somemethod();

You can pass a reference to class0 to the constructor of class1, then
call class0 functions through the reference object.

class 1 = new class1(this);
