[Boost-users] Newbie question filesystem

I lost my copy of metaprogramming. I'm ordering another tomorrow. But 
here is what I'm up to.

I've been doing the virtual path thing with old MFC classes and such, like:
C:\\cpp\\RA_User_2_2\\$(TEST)
or
$(PATH)\$(TEST) etc.

What I'm trying to do is derive from filesystem and wrap this virtual 
stuff around it to break away from the old stuff I have, (ugly stuff). 
I've gotten to the point where I'd like to snap different virtual sets 
in and don't want to build on the old stuff, filesystem is really cool. 
I have a client that has several clients and wants to set his 
configurations on the fly to handle them, I do it in code for myself, 
but it is not runtime. Anyway...

So I started with:

template<class String, class Traits> class basic_vpath;
typedef basic_vpath< std::string, path_traits > vpath;

template<class String, class Traits> class basic_vpath
     :public basic_path< String, Traits >
{
};

But I don't understand why I can just fine:
     CString strUserDirectory= _T("C:\\cpp\\RA_User_2_2\\$(TEST)");
     path aPath( strUserDirectory );

But can't convert from CString, or even std::string with:

     CString strUserDirectory= _T("C:\\cpp\\RA_User_2_2\\$(TEST)");
     vpath aPath( strUserDirectory );

I'm trying to extend what I see in path.hpp without success, and I've 
tried lots of stuff. Something to do with the converters?

Thanks, Dan.
