Drinks coffee, re-reads docs, and problem solved. ForEachCollectionInChannels(pAmp,bind(ForEachProperty,_1,protect(bind(&CalcP ropCurValMaxWidth,_1,var(m_ChanCols))))); Cheers, Richard.

Hi,

I'm trying merge some code some of which uses a mixture of BB and BLL to just use the BLL under VC7.1. Having changed some 200 expressions without incident if find I can't see the wood for the trees here.

The existing code, working with BB, is;

typedef boost::function FECCFunc; void ForEachCollectionInChannels(IAmplifier* pIAmp,FECCFunc const & fec);

typedef boost::function FEPFunc; void ForEachProperty(ICollection* pCollection,FEPFunc const & fep);

void CalcPropCurValMaxWidth(IProperty* pProp,CColumnMap& map);

...

void Problem() { CColumnMap m_ChanCols; IAmplifier* pIAmp; ForEachCollectionInChannels(pAmp,bind(ForEachProperty,_1,cref( bind(&CalcProp CurValMaxWidth,_1,ref(m_ChanCols)))); //Here }

What's the equivalent with using BLL?

Thanks,

Richard.
