[Longmcx]

Hi everybody!
i have a problem with my code. in my source code file, i write:

//////////////////
class Cline : public CObject // create class CLine
{
public:
CPoint m_from;
CPoint m_to;
public:
void Addline( );
};
typedef CtypedPtrArray<CObArray, Cline*> MyLines ;
//////////////////

But i alway receive error :

you need define file:
#include <afxcoll.h>
