Hi, I've tried that, and I got a bunch of errors. I'm using boost::bind for that, not boost::lambda. Here is the error The following line: std::transform(array.begin(), array.end(), std::back_inserter(tr), bind(&std::string::replace, bind(&Foo::get, _1), 0, 5, "")); generates: error: no matching function for call to 'bind(<unknown type>, boost::_bi::bind_t<const std::string&, boost::_mfi::cmf0<const std::string&, Foo>, boost::_bi::list1<boost::arg<1> > >, int, uint32_t&, const char [1])' Kobi.

I know it should be something like: std::transform (array.begin(), array.end (), std::back_inserter(tr), bind(&Foo::get, _1));
So here I'm stuck. The bind function will know to extract the string using get. But how to I get that string and do something like: bind(&std::string::replace (???))
I'd use straight Boost.Bind, not Lambda. But the syntax is the same:
std::transform(array.begin(), array.end(), std::back_inserter(tr), bind(&std::string::replace, bind(&Foo::get, _1), 0, 5, ""));
Or you could use one of the special iterators from Boost.Iterator instead of the nested bind.
