Hi Fokes: I'm trying to convert a BOOST_FOREACH loop to use the new lambda syntax: I have a ptree variable declared in a class of which the foreach is part. I also have a vectorstd::wstring that I need to use within my lambda. This all being the case, the following is the original BOOST_FOREACH: BOOST_FOREACH(boost::property_tree::ptree::value_type &v, IniTree) IniSections.push_back(ConvertToWString(v.first)); And the following is the converted lambda: std::for_each(IniTree.begin(), IniTree.end(), [&] (boost::property_tree::ptree::value_type &v) { IniSections.push_back(ConvertToWString(v.first)); }); Is this the right way to go about the conversion-have I missed anything? Any help appreciated. Regards Sean.
