VC++ 8 displays dozens of error messages with the first one:

error C2665: 'boost::lambda::function_adaptor<Func>::apply' : none of the 2 overloads could convert all the argument types

Can anyone tell me how I need to change the lambda expression?

As usual I found the answer immediately after having sent the question - it must be &to: std::for_each(from.begin(), from.end(), if_then(bind(&sample::odd, _1) == false, bind(&std::vector<sample>::push_back, &to, _1))); Boris
