am i not supplying the correct amount of parameters to the find method?

Sort of, there are actually two problems here. The first is that std::string::find has 2 overloads with one parameter and the compiler doesn't know which one to use. The solution is to cast it to the correct type, ie. static_cast(&std::string::find) Which is pretty ugly. The second problem is that this won't work if find is defined as a two argument method, with a default value for the second argument (as it seems to be for gcc). In which case you do need to use a second argument. This is pretty messy and hard to do portably (unless anyone knows better?). I wouldn't use Boost.Lambda for anything this complicated. I think some work has gone into making this kind of thing easier in phoenix. But Boost.ForEach is probably the best solution here. Or you could put the loop body in a separate function. Hope that helps. Daniel
