Re: [Boost-users] How to pass a member variable with boost::ref() inboost::bind()?

Since ONE_RECORD can be large, I prefer to calling bind() as method 2, but, compiled under VC7.1 it generates such an error: [...]

_1 is always a reference to the first argument. You don't need to wrap it with ref().
