关于CObList的问题,急用!

[tganan]

小弟需要用CObList构造一个链表,可是没有用过!急问各位!
class point : public CObject
{
private:
int index;
double x;
double y;
double z;
CObList *list;//连接另外一个链表
public:
void *iniList(CObList *temp);
CObList *GetList(){return list;};
}
class list: public CObject
{
public:
int index;
int num;
}
请问point链表如何来做,同时,如何建立list链表?

1.CTypedPtrList<CObList,CYourType*>m_CYourTypeList;

2.CArray<CPoint,CPoint&>m_pointArray;

这两句是申明.

下面是往链表中添值,其中:
CYourType *pMyType=NULL;
pMyType=new CYourType;
pMyType->m_pointArray.Add(CPoint(x,y,z));//给pMyType赋值
m_CYourTypeList.AddTail(pMyType);//这样链表中就有你存的值了

[tganan]

PointList *ppntlist = new PointList;
for(i=0;i<itemNumb;i++)
{
ppntlist->SetIndex(i);//SetIndex(int i){index = i;};
ppntlist->SetX(DotStru[i].X);//SetX(double x){X = x;};
ppntlist->SetX(DotStru[i].Y);//SetY(double y){Y = y;};
ppntlist->SetX(DotStru[i].Z);//SetZ(double z){Z = z;};
m_PntList.AddTail(ppntlist);
}
for (POSITION pos = m_PntList.GetHeadPosition(); pos != NULL; )
{
PointList* pObj;
pObj = m_PntList.GetNext(pos);//**//
www.Format("%d,%.3f,%.3f,%.3f\r\n",pObj->GetIndex(),pObj->GetX(),pObj->GetY(),pObj->GetZ());
csb+=www;
}
AfxMessageBox(csb);

提示说://**//行不能从CObject*转换为PointList*
请问,如何解决!
