I am trying to port the following VC8 code to boost. I need to know what are the equivalent methods in boost:: namespace for the following:

1) m_nNumGroups data memeber of class CAtlREMatchContext

2) GetMatch( ) method of class CAtlREMatchContext

 

I have gone through the boost documentation but could not suceed.

 

            for (UInt32 ulGroupIndex = 0; ulGroupIndex < atlMatchContext.m_uNumGroups; ++ulGroupIndex)
            {
                const CAtlREMatchContext<>::RECHAR* pszStart = 0;
                const CAtlREMatchContext<>::RECHAR* pszEnd = 0;
                atlMatchContext.GetMatch(ulGroupIndex, &pszStart, &pszEnd);
                int nLength = static_cast<int>(pszEnd - pszStart);
                strTemp = pszStart;
                strTemp = strTemp.substr(nLength);
                AcMs::trimString(strTemp, true, true);
                switch(ulGroupIndex)
                {
                case MsV7ImgMgrImgIndexType::kViewNo:
