Peter, you are better! I think that should be simple solution. Thank you!

Now I want to write something more difficult:

apReports.push_back(make_report(boost::lambda::bind(&CItem::GetItemCount)*boost::lambda::bind((&CItem::GetItemBytes)));

or

apReports.push_back(make_report(boost::lambda::bind(&CItem::GetItemCount)*100.0/boost::lambda::bind((&CItem::GetTotalCount)));

Is there any way to make it with boost library?
