模板集合类CTypedPtrArray::Add()访问错误

Question

调用int Index=pDoc->m_AddressList.Add(pList)增加一组数据到数组中，为何显示：Access violations！！

其中：CTypedPtrArray<CObArray,CAddressList*>m_AddressList;

         class CAddressList : public CObject

{
}

Answer 1

Debug下打开call stack窗口，看看函数调用堆栈，找到出错的函数。
int Index=pDoc->m_AddressList.Add(pList);  // Debug下看看pDoc指针的是否有效？

Debug调试下显示：CObject下数据成员m_pData 、m_nSize 、m_nMaxSize m_nGrowBy 错误。 Error:Expression cannot be evaluated！！.此程序是多文档。                          而(DefineClass*)pDoc=(DefineClass*)pMain->GetActiveDocument();

而框架我用CFrameWnd*pMain=(CFrameWnd*)AfxGetApp()->m_pMainWnd;这里有问题？？
