CTypedPtrList使用的问题

[aguo8853]

照着教程做的例子，在工程的类中定义了 CTypedPtrList<CObject,CCommodity*>m_list;
（CCommodity是自定义的基于COject的一个类）

并需要执行 m_list.IsEmpty() 和 m_list.GetTailPosition()

但编译出现了下面的错误（stdafx.h中添加了#include<afxtempl.h>）：

:\microsoft visual studio\mfc\include\afxtempl.h(1566) : error C2664: '__thiscall CObject::CObject(const class CObject &)' : cannot convert parameter 1 from 'int' to 'const class CObject &'
Reason: cannot convert from 'int' to 'const class CObject'
No constructor could take the source type, or constructor overload resolution was ambiguous
f:\microsoft visual studio\mfc\include\afxtempl.h(1566) : while compiling class-template member function '__thiscall _CTypedPtrList<class CObject,class CCommodity *>::_CTypedPtrList<class CObject,class CCommodity *>(int)

和'IsEmpty' : is not a member of 'CTypedPtrList<class CObject,class CCommodity *>'这样的错误

有什么解决的办法？？

把CTypedPtrList<CObject,CCommodity*>m_list;中的CObject换成CPtrList应该就对了！

Base class of the typed pointer list class; must be a pointer list class (CObList or CPtrList).
