Hi Carla,

StringFromGUID2 outputs the string form of the guid with braces,
ie:
{c200e360-38c5–11ce-ae62-08002b2b79ef}
But, operator>>(istream&, uuid&) does not expect the braces.  It expects
the uuid string in the form: c200e360-38c5–11ce-ae62-08002b2b79ef  As you
 discovered, string_generator accepts both forms and from wide or narrow
strings. The following should work:
   WCHAR guid_buf[50];

      StringFromGUID2(guid_value, guid_buf, 50);

      boost::uuids::uuid uuid_test =
boost::uuids::string_generator()(guid_buf);
Regards,
Andy.

I actually think I can use the boost uuid generator.

It worked in my testing :O)

  I am trying to convert a legacy GUID on mircosoft to use the
  boost uuid.

  I am utilizing the stringstream as mentioned in the boost uuid
  documentation.

  I have managed to get the GUID converted into a string but am
  unable to inject the string value

  Into the uuid variable.

  Below is just a snippet of a test program.  I read it back
  into a buffer variable to make sure that value was properly

  set.  ss gets the value of guid_str but  does not set the
  value in uuid_test.

        WCHAR guid_buf[50];

        Boost::uuids::uuid uuid_test;

        StringFromGUID2(guid_value, guid_buf, 50);

        char *guid_str = OLE2A(guid_buf);

        std::stringstream ss;

        char buf[50];

        ss << guid_str;

        ss >> uuid_test;

        ss << uuid_test;

        ss >> buf;

  Obvioulsy I am using stringstream wrong.  Does anyone know how
  to convert a GUID to a boost UUID?  I can’t seem to find the
  documentation or interface.
