That's too funny, Karl. I had just sent a note to the list on the RandString UDF in reply to an earlier note by Mark Handy. Don't want anyone to confuse the two: Karl's referring to the built-in RandRange function in CF. I can see that the RandString UDF does not guarantee non-repetition. I'll bet that's a feature you could easily add to it (using a new argument to request that characteristic) and contribute it as an update to UDF in the library. That's what's great about the library.
Though I don't think it suits your needs, I'll point out that there's another UDF there called MakePassword that "Generates a random 8-character password that is free of annoying easily confused characters such as 1 or l, O or 0." Don't know if that's at all related to the problem you were trying to avoid/solve, but it's another piece of code that may be worth looking at. /charlie > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On > Behalf Of Karl Zarudny > Sent: Thursday, March 28, 2002 11:12 AM > To: CFUG > Subject: [CFTALKTor] RandRange question - Unique random numbers > > > Hi everybody. > > I'm using RandRange to generate random numbers within a cfoutput. > How can I > ensure that there is no repetition?
