To define an operator out side of a class, you place "friend" before the return type.

or you might do it like this (have not tried, but is should work):

class A {
public:
A(int x) :num(x) {}
~A() {}
int GetVal() {return num;}
private:
int num;
};
friend std::ostream& operator<<(std::ostream& o,A& a) {return o << a.GetVal();}

case WM_KEYDOWN:
   if (wParam == VK_MENU)

case WM_KEYUP:
