again on function pointer

hi all,

could anyone explain me why this doesn't compile??

#include<iostream>

using namespace std;
class test;

class messenger
{
public:
messenger(void(test::*p_f)() = 0)
: m_f(p_f)
{
}

void
call()
{
(*this.*m_f)();
}

void
set(void(test::*p_f)())
{
m_f = p_f;
}

void (test::*m_f)();
};

class test
{
public:
test()
: m(0)
{
m.set(&test::f);
}

void f()
{
cout << "Hallo! " << endl;
}

messenger m;
};


int
main()
{
test a;
a.m.call();
return 1;
}

thanks
e

No fair asking about code that doesn't compile without
quoting the error message.

m_f points to a member function of class test.

(*this) is an object of class messenger.

You cannot call a test member function on a messenger object.
