Here is another snippet of code for you to look at and tell me what is wrong.  As before, give your comment of what is wrong and I will post the answer and make the comments public tomorrow.  This time it is C++ code and not specific to ASP.NET:

typedef bool (FUNC)(void *);

class Foo
{
    virtual FUNC Method;

    void *m_p;
};

bool Foo::Method(void *p)
{
    return  p == m_p;
};
