Here's the code I ran as a test:
THis is alan's<br>
<cfloop from ="1" to ="5" index="z">
<cf_uuid>
<cfoutput>#UUID#<br>
</cfoutput>
</cfloop>
and this ain't...<br>
<cfloop from ="1" to ="5" index="z">
<cfoutput>#CreateUUID()#<br>
</cfoutput>
And here is the results:
THis is alan's
C81EFB22-B071-B071-97B6-97B97267850BE506
655DA5B9-5D90-5D90-34E4-34E409FEEB603949

65A9D22E-5DF9-544C-444C-44403662FB4DE5E3
and this ain't...
6505F7EA-D2E1-11D4-B17000E0295FC366
6505F7EB-D2E1-11D4-B17000E0295FC366

6505F7EE-D2E1-11D4-B17000E0295FC366
Now, the box I'm running this on is my development box, a Pentium Pro 200,
Win NT 4.0, SP6a, CF4.5.1 Ent Ed SP1. Tell me, what is the setup you ran
your createUUID() test on?
