上面是邮件头信息，假如我要截获一部分内容，1---2这段的字符串应该怎么做

Answer 1

从From到X-Envelope-From: 截断咯：）

Answer 2

CString sHeader  ="字符串";
CString strContype,strBoundary; 
startpos=m_sHeader.Find("From");
if (startpos < 0)
return false;
endpos=m_sHeader.Mid(startpos).Find("Path: ");
strContype = m_sHeader.Mid(startpos+2,endpos+1);
其它自己去试下
