I have been trying to compile the following code with VC 7.1 ( which compiled fine with VC 6 ) with no luck.

std::string m_rBuffer; boost::regex m_rStartExp;

string::const_iterator rRawDataBegin = m_rBuffer.begin(); string::const_iterator rRawDataEnd = m_rBuffer.end();

boost::cmatch rStartMessage;

unsigned int flags = boost::match_default; while ( boost::regex_search(rRawDataBegin, rRawDataEnd, rStartMessage, m_rStartExp, flags) )

Included is the compiler error report.

The match-flags area distinct type, so use: boost::match_flag_type flags = boost::match_default; John.
