网上应该很多这个代码，我运行这个代码之后就出现
list_s.cpp文件的171行
POSITION CStringList::AddTail(const CString& newElement)
{
ASSERT_VALID(this);
CNode* pNewNode = NewNode(m_pNodeTail, NULL);
pNewNode->data = newElement;
if (m_pNodeTail != NULL)
m_pNodeTail->pNext = pNewNode;
else
m_pNodeHead = pNewNode;
m_pNodeTail = pNewNode;
return (POSITION) pNewNode;
}
研究了下应该是
//增加一列标题栏字符
void CMyscanDlg::AddHeader(LPTSTR hdr)
{
if(m_pColumns)
m_pColumns->AddTail(hdr);
}
这个函数出问题了，但是不知道怎么改，就把添加标题栏的方式换了一种。
结果窗口出来了，但是开始扫描之后就显示已停止工作_（:3」∠）_
debug检查弹出的窗口显示unhandled exception in *.exe (MFC42D.DLL):0xC0000005:Access Violation
已经不知道怎么改的我，求大神指点
