Hello,

Here's an example of my problem:

#include <algorithm> #include <vector>

#include

class TheClass { };

void accept(TheClass& tc) { }

int main() { std::vector cont;

// Compile error - how to dereference _1 ??? std::for_each(cont.begin(),cont.end(),boost::bind(&accept,_1)); }

How can I dereference _1 so I can use the accept function?

#include <algorithm> #include <vector>

#include #include

class TheClass { };

void accept(TheClass& tc) { }

int main() { using namespace boost; using namespace boost::lambda;

std::vector cont;

// Compile error - how to dereference _1 ??? std::for_each(cont.begin(),cont.end(),bind(accept,*_1)); }

Hi Rob, with std::for_each(cont.begin(),cont.end(),bind(&accept,*_1)); you can dereference _1. Best regards Franz
