[Boost-users] Question about using Boost::for_each function to set a local variable if a condition is met

Hi, I am trying to Boost::for_each function to set a local variable if all elements in this is DEFAULT type. Here is my code, but I don't know how to implement the last part of the if_then call. boolean rtnValue = false; for_each(mylist.begin(), mylist.end(), if_then( bind(&ListItem::getType, _1) == DEFAULT, set the local value to true if true if all of them are DEFAULT type )); if you can give me some pointers, I will be appreciated. Thank you.
