error C2664: 'inet_addr' : cannot convert parameter 1 from 'CString' to 'const char *'
       No user-defined-conversion operator available that can perform this conversion, or the operator cannot be called

        Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast
