I am getting the following error message during compilation of my C++ program on XP laptop using .NET libraries:

ossxerces_utils.cxx

You can't assign to objects of type basic_ofstream. The copy-assignment
operator
cannot be generated because members or bases are not copy-assignable.

What are you trying to do?

Iterators are modelled after pointers. But they need not be pointers. VC 6
uses
pointer types for vector iterators. In VC7+ there are distinct types for
iterators.

You should probably use a std::vector<OssDataTag>::iterator or
std::vector<OssDataTag>::const_iterator. If you really want to obtain a
pointer
from an iterator you can still use &*iter. E.g.

std::vector<int> v;
std::vector<int>::iterator i = v.begin(); // OK
int* p = &*v.begin(); // OK
