how i convert guid string from widestring to unicode string

Question

i have this problem, doing:

function GenGuid: String;
var
  guid: TGuid;
begin
  CreateGuid(Guid);
  Result := GuidToString(Guid);
end;

It return a guid in string format. But i how do to convert a widestring to unicodestring? I need to have the guid in unicode string format. Thanks very much.

UPDATE

  function myguid: string;
  var
    i: Integer;
    s: string;
    Guid: TGuid;
    t: byte;
  begin
    CreateGuid(Guid);
    s := GuidToString(Guid);
    for i := 1 to Length(s) do
    begin
      t := Ord(MidStr(s, i, 1));
      writeln (t);
    end;
    Result := ....  // for now not need, just a test
  end;

Doing so, t return 148-124 always and not ascii of single character. If i not do ord( ) then display char correctly.

I'm not sure if that's what you really want.

uses
  ComObj, ActiveX;

function CreateGuid: string;
var
  GUID: TGUID;
begin
  Result := '';

  if CoCreateGuid(GUID) = S_OK then
  begin
    Result := IntToHex(GUID.D1, 8) +
              IntToHex(GUID.D2, 4) +
              IntToHex(GUID.D3, 4) +
              IntToHex(GUID.D4[0], 2) +
              IntToHex(GUID.D4[1], 2) +
              IntToHex(GUID.D4[2], 2) +
              IntToHex(GUID.D4[3], 2) +
              IntToHex(GUID.D4[4], 2) +
              IntToHex(GUID.D4[5], 2) +
              IntToHex(GUID.D4[6], 2) +
              IntToHex(GUID.D4[7], 2);
  end;
end;
