CMap: Mapping CString to CStringArray

Just a simple MFC trick. To map from CString to CStringArray use:

CMap<CString, LPCTSTR, CStringArrayX, CStringArrayX&>

where CStringArrayX is defined as:

class CStringArrayX : public CStringArray
{
 public:
 CStringArrayX() {}
 CStringArrayX(const CStringArrayX &qSource);
 CStringArrayX &operator = (const CStringArrayX &qSource);
};

CStringArrayX::CStringArrayX (const CStringArrayX &qSource)
{
 SetSize (qSource.GetSize());

 for (long c=qSource.GetSize()-1; c>=0; c--)
   (*this)[c]=qSource[c];
}

CStringArrayX &CStringArrayX::operator = (const CStringArrayX &qSource)
{
 SetSize (qSource.GetSize());

 for (long c=qSource.GetSize()-1; c>=0; c--)
   (*this)[c]=qSource[c];

 return (*this);
}

Hopefully this post keeps some people from searching as long as I did… 😉
