And? What's the problem with it? Is it not possible to access static vars in a
member function?

Of course the opposite way can not work: Access non static member vars from a
static member function.

Well the equivalent C++ programm works:

class A
{
public:
        static int v;

        int getv()
        {
                return v;
        }
};

int A::v = 1;

int _tmain(int argc, _TCHAR* argv[])
{
        A a;

        printf("%d\n", a.getv());
}

your instance of A is null

This should work:

void main(char[][] args)
{
        class A
        {
                static int v = 1;

                int getv()
                {
                        return v;
                }
        }

        A a = new A;
        assert (a.getv() == 1);
}

OHH! Sorry! I have to get used to that classes are allways references!

Sorry again! - I put it to INVALID
