Hello!

I'm trying to create a dictionary with both key and value of type
'CString'. I declare the object of 'CMap' so it is as closer to
std::map, as possible:

CMap<CString, const CString&, CString, const CString&> m_appLangs;

and semantically it's like this:

std::map<std::string, std::string> m_appLangs;


You can use the pre-made class CMapStringToString instead of creating your
own.



But it seems 'CMap' is not realized as an RB-tree, I guess it must be
realized through hash table. The problem is when I make the above
declaration, my source file refuse to compile. Here is the simplified
error message:

cannot convert from 'const CString' to 'DWORD_PTR'
see reference to function template instantiation 'UINT
HashKey<ARG_KEY>(ARG_KEY)' being compiled with
[ARG_KEY=const CString &]


Not sure why this is, maybe it doesn't like either the "const" or the '&'.
