MFC n00b here, I'm trying to serialize a std::map obj into disk. I keep
getting compile errors with the code:

ar<<storeIt

in which ar is a CArchive obj and storeIt is the map obj's iterator (the
code above is inside a for loop that loops through the elements in the map).
My map is like this:
std::map<CString,CGPoint> with CGPoint being a class with 2 float members X
and Y. When I change my code to:

ar<<(*storeIt).first;
ar<<(*storeIt).second.X;
ar<<(*storeIt).second.Y;

it works. Is it because MFC can't serialize std::map objects directly to
file (1st code snippet) and requires each part of the map to be serialized
individually (2nd code snippet)?
