Serialize Linked List

[Esaias Pech]

I made a list of points:

class CPuntoList : public CObject
{

public:
CPunto* raiz;
CPuntoList();
void Inserta(CPunto* nodo);
virtual ~CPuntoList();
virtual void Serialize(CArchive &ar);
long getSize();
}

The serialize function of the List looks like this:

void CPuntoList::Serialize(CArchive &ar)
{
CObject::Serialize(ar);
long i;
if(ar.IsStoring())
{
ar<<raiz;
}
else
{
ar>>raiz;
}
}

the Punto Class looks like this:

class CPunto : public CObject
{
public:
CPunto();
CPunto(double _x, double _y, double _z, double _zTn);
CPunto *m_pSigPunto; // Pointer to the next point
CGLColor *m_pColor;
void Inicializa();
virtual ~CPunto();
virtual void Serialize(CArchive& ar);
public:
double x, y, z, zTn;
private:
DECLARE_SERIAL(CPunto)
};

Serialize functino looks like this:

void CPunto::Serialize(CArchive &ar)
{
CString str;

if(ar.IsStoring())
{
	ar<<x;
	ar<<y;
	ar<<z;
	ar<<zTn;
	ar<<m\_pColor;
	ar<<m\_pSigPunto;	//	Pointer to next point (Linked list)
}
else
{
	ar>>x;
	ar>>y;
	ar>>z;
	ar>>zTn;
	ar>>m\_pColor;
	ar>>m\_pSigPunto;	//	Pointer to next point (Linked list)
}	

}

Now the question is: When I load about 200 points to the list or even 5,000 points and I save the data to a file using the serialize functions everything works fine, both the storing and the loading. But when I try to save about 12,000 points, there is an error in both storing and loading, it says "Stack overflow." I think because from one function (the serialize function) I call the a serialize function over and over so the Stack overflows... Is that the problem? or what could be the issue? anyways, more importantly, how can I solve it?? Please help!!!!

you are right calling so often the stack is a problem. Somehow is it possible to enhance the stack. But it is bad style. (if you call a lot more you run in the same trouble) You better Serialize the points one ofter the other. The linked list stays otuside the serialization.

sounds like your loading ar with to much info to write at once, try writing chunks when ar reachs a set size then clear ar repeat, until all data is written
