pointer woes

[Ant]

Hi,

I am having trouble with a member function pointer. It sees to give me the
followign error

Run-Time Check Failure #0 - The value of ESP was not properly saved across a
function call.

It only seems to give me problems if I use the friend class declaration

Any thoughs ?

Code Follows:
#include "rootclass. h"

int _tmain(int argc, _TCHAR* argv[])
{
CRootClass *testclass;
testclass = new CRootClass;
testclass->TestFunction() ;

delete testclass;
return 0;
}
class CStore
{
public:
CStore(void);
~CStore(void);
friend class CRootClass;
typedef void(CRootClass ::*FunctionPtr) (void);
void PassPtr(Functio nPtr FPtr);
};

#include ".\store.h"

CStore::CStore( void)
{
}

CStore::~CStore (void)
{
}

void CStore::PassPtr (FunctionPtr FPtr)
{
//something happens with ptr
}

#include ".\store.h"
class CRootClass
{
public:
CRootClass(void );
~CRootClass(voi d);

CStore *m_Store;
void TestFunction(vo id);
};
#include ".\rootclas s.h"

CRootClass::CRo otClass(void)
{
m_Store = new CStore();
m_Store->PassPtr(&CRoot Class::TestFunc tion );
}
CRootClass::~CR ootClass(void)
{
delete m_Store;
}
void CRootClass::Tes tFunction(void)
{
//some code
}

As your code is incomplete, I'm going to guess based on symptoms. I
guess
you're improperly mixing member function pointers and normal function
pointer.
This probably takes the form of a C cast, or a reinterpret_cas t.

NB. Pointers to static member functions have the same type as to free
functions.
