VC + + Error C2248: "Cobject::cobject": Cannot access private member (declared in "CObject" Class)

This error often occurs when using classes such as: CArray or CList.

The cause of this error is due to the custom class's array entry

There is an operation like ADD () in this operation, actually need a = operation, but this = operation is not implemented in the custom class, so, the program automatically go to its parent class is the CObject class to find, but found a class of this = is a private then reported this A mistake.

Knowing the cause of the solution is natural, that is, in the custom class overloaded operator = overload after this error is gone.

class  Public cobject{public:    coptrect ();     virtual ~coptrect ();     // start range of the Operation     CRect m_optstartrect;     // end range of the Operation     CRect m_optendrect;     // Target Interface    of the operation int M_optdessurface;    Coptrectoperator = (Coptrect & src);};

Implementation code

coptrect::coptrect ()    : m_optdessurface (0) {}coptrect::~coptrect () {}coptrect & Coptrect::operator = (Coptrect & src) {    this->m_optdessurface=  Src.m_optdessurface;     This->m_optendrect = src.m_optendrect;     This->m_optstartrect = src.m_optstartrect;     return *this;}

So after implementing this custom class, start using it

Define the array of variables first

Carray<coptrect, coptrect&> Optarray;

After this array, we use a command that adds a new element

// add an action area to the interface void int Desid) {    coptrect ort;     = Start;     = End;     = Desid;    Optarray.add (ORT);}

After doing so, do not report the above error! Problem solving
