Hi Dennis, There is something strange: Indeed, when I look at the generated UUID in 4D the 15th hex digit is always 4 But, as far as I know the docs say : "set the four most significant bits of the 7th byte to 0100'B, so the high nibble is 4" This means that the 13th hex digit must be 4
And in fact, my 4D generated UUID is rejected by the web service, saying it isn't a 4 version UUID Has this something to do with byte swapping or something? What should I do? This has been tested with 4D v16R6 on a 64-bit Windows laptop Gr, Piotr > -----Oorspronkelijk bericht----- > Van: Dennis, Neil <neil.den...@umb.com> > Verzonden: donderdag 5 juli 2018 17:06 > Aan: 4D iNug Technical <4d_tech@lists.4d.com> > CC: Piotr Chabot Stadhouders <p.stadhoud...@timeff.com> > Onderwerp: RE: UUID version 4 needed > > > Does anybody know how to generate an UUID version 4 > > Doesn't 4D already generate version 4 UUIDs?
