lo, I know I can create a pointer to a normal function but, does anyone know if there''s any way to create a pointer to a member function? Cheers, Case

Here is one solution.

  
class XYZ
{
public:
   ...
   void DisplayObject(const unsigned nPos);
};

typedef void (XYZ::*DObjPtr)(const unsigned nPos);

DObjPtr pFunction = &XYZ::DislayObject;

don''t forget - member functions are members of an object. so you have to associate an object with the function pointer before you can call it.

the only exception is static member functions which don''t use any member data so don''t need an object (and don''t get a ''this'' pointer passed to them)

the function-pointer link should do you fine.
