怎么也找不出错误

[shang0636]

如下代码
typedef struct : public CObject
{
public:
double x;
double y;
double z;
}SPACEPOINT;
typedef CArray<SPACEPOINT,SPACEPOINT> POINTLIST;
......
POINTLIST m_pointlist1;
SPACEPOINT spoint;
spoint.x=1;spoint.y=1;spoint.z=1;
m_pointlist1.Add(spoint);//!!!!error C2664: 'Add' : cannot convert parameter 1 from 'SPACEPOINT' to 'SPACEPOINT'
各位能否帮个忙

取消public CObject
typedef struct spacepoint
{
public:
double x;
double y;
double z;
}SPACEPOINT;

Compiler Error C2644
basis class 'class' for pointer to member has not been defined

A pointer was declared that pointed to a class that was declared but not defined.

The following is an example of this error:

class C;
int C::* cp; // error, C has not been defined
class D {};
int D::*dp; // OK

真是高人，不知能否讲下原因，还有我定义了如下函数，
void Draw(POINTLIST pointlist,SPACEPOINT viewpoint,CDC *pDC);
再调用时Draw(m_pointlist1,m_viewpoint,pDC);出现了以下错误
error C2664: 'Draw' : cannot convert parameter 1 from 'class CArray<struct SPACEPOINT,struct SPACEPOINT>' to 'class CArray<struct SPACEPOINT,struct SPACEPOINT>'
No copy constructor available for class 'CArray<struct SPACEPOINT,struct SPACEPOINT>'
