Hi:
I am declaring a property_tree, pulating this with an ini file.
I then need to find out whether a section (key) is present, so I'm doing:
boost::property_tree::ptree::assoc_iterator it =IniTree.find(key);
                if (it !=boost::property_tree::ptree::not_found)
using visual c++ 2010 I get an error c2678, telling me that no operand is able to use these two values.
Can someone please tell me what I'm doing wrong, as I can normally do this for std::vectors etc!
Cheers
Sean.
