Hi,

my solution is not the most elegant one, of course, but I would do something
simple like this:

<code>

//
// Control.h
//

// Your singleton control
class Control
{
public:

  Control()
  ~Control();
....

private:
  // Ban copy
  Control( const Control & );
  Control & operator=( const Control & );
};

// Access the control instance
Control * GetControlInstance();

//
// Control.cpp
//
#include "Control.h"

// The singleton instance
// (private to this .cpp module)
static Control theControl;

Control * GetControlInstance()
{
  return &theControl;
}

</code>

Basically, you make the instance private to a .cpp module (using static
keyword), and you publicly expose a function to get the instance pointer
(GetControlInstance()).
