Communicating between 2 classes

[TGF]

Hello,

I have a little dilemma (At least it is to me). I have two classes, Class
A and class B, where Class A contains the UI thread and class B contains
another thread. I want to be able to communicate from ClassA to ClassB and
then from ClassB to ClassA. The problem comes in with the include files.
It seems there is some sort of overlapping where one is not defined when it
is supposed to be. This is expected and I cannot seem to find a decent
solution for it. Here are the classes. As you can see from the below
example. I cannot do both. If I take out the 'include <"classA.h"> from the
ClassB declaration and remove the parentClass member from ClassB, I can
communicate downward but not upward. Any help would be appreciated.

#include <"classA.h">
#include <"classB.h">
namespace App
{
public __gc ClassA : public System:Windows:Forms:Form
{
public:
...
private:
...
ClassB __gc *subclass;
...
};
}

#include <"classA.h">
#include <"classB.h">
namespace App
{
public __gc ClassB
{
public:
...

private:
...
ClassA __gc *parentClass;
...
};
}

If I'm not mistaking those are header files, and you're trying to
#include a file from itself. The corrections below are valid if we're
talking about header files. Also I never worked with managed
functions, but there shouldn't be any differences...

Move both includes from here to classA.cpp and add here:
class ClassB;
namespace App
{
public __gc ClassA : public System:Windows:Forms:Form
{
public:
...
private:
...
ClassB __gc *subclass;
...
};
}
Another header file, I presume...
#include <"classA.h">
#include <"classB.h">
Move both includes from here to classB.cpp and add here:
class ClassA;
namespace App
{
public __gc ClassB
{
public:
...

private:
...
ClassA __gc *parentClass;
...
};
}
