[Boost-users] issue when using boost::tokensizer with std::wstring.

17 Jan 2011


      Hi:
I'm trying to use boost::tokenizer and have included boost/tokenizer.hpp.
I get the errors below when trying to compile the following code:
std::wstring TokensStr(Item);
       boost::tokenizer<> Tokens(TokensStr);
Item, is defined as a BSTR.
the errors are:
     1>c:\program files\boost\boost\tokenizer.hpp(59): error C2664: 'std::_String_const_iterator<_Elem,_Traits,_Alloc>::_String_const_iterator(const std::_String_const_iterator<_Elem,_Traits,_Alloc> &)' : cannot convert parameter 1 from 'std::_String_const_iterator<_Elem,_Traits,_Alloc>' to 'const std::_String_const_iterator<_Elem,_Traits,_Alloc> &'

Does anyone know how I can solve these errors.
Any help appreciated.
