  I've created a class that I want to use as a vector.
  Everything seems to be fine except that I'm running into a compiling error:
  error C2678: binary '<' : no operator found which takes a left-hand operand of type 'const std::string' (or there is no acceptable conversion)
  
  I'm a little lost on how to fix it.
  
  Thanks In advance:
  
  class part_info
  {
  public:
      string part_no;
      string raw_qty;
      int qty;
      int ref;
      const operator<(part_info&) const;
  
      part_info() : part_no(""), raw_qty(""), qty(0), ref(0) {}
      part_info(string NewPartNo, string NewRawQty, int NewQty, int NewRef) : part_no(NewPartNo), raw_qty(NewRawQty), qty(NewQty), ref(NewRef) {}
  };
  
  bool operator<(const part_info& x, const part_info& y)
  {
      return x.part_no < y.part_no;
  }
  
  typedef vector<part_info> NAMEVECTOR;

  Hi,
  
  Do you have included the 'string' class ?

  #include <string>
  using std::string;
