Thanks for help,

but I want to assign the value of the member variable not the pointer itself:

vector<boost::shared_ptr<clss> > tmp

for(size_t i=0; i<tmp.size(), i++)
tmp[i]->mem = 0.0;

In this case clss::mem should be changed, I get an error doing

std::for_each(tmp.begin(), tmp.end(), &_1::mem = 0);

Can this be done?

Thanks for help
