Re: [Boost-users] [BLL] How to search in a list for an object comparinga data member?

...

struct Foo { int fDataMember;}

int main() { std::vector<Foo> foos; Foo fo; std::find_if(foos.begin(), foos.end(), _1->fDataMember == fo.fDataMember); //<-- won't compile; }

As your vector is of Foo, not Foo*, did you mean "_1.fDataMember" ? If so, you can do this: std::find_if(foos.begin(), foos.end(), bind(&Foo::fDataMember,_1) == fo.fDataMember); That assumes: #include <boost/lambda/lambda.hpp> #include <boost/lambda/bind.hpp> using namespace boost::lambda;

I imagine you're having trouble with "_1->fDataMember".

I didn't realize there was a limitation when using "->". Surely there must already be something in the lambda library to deal with this? It seems like something that must come up a lot. Darren
