As simple-to-remember-but-unique confirmation numbers, I need to
generate six random characters (ASCII 65 to 90, inclusive):
Randomize()
objStringBuilder.Append(Chr(CInt(Int((25 * Rnd()) + 65))))
Randomize()
objStringBuilder.Append(Chr(CInt(Int((25 * Rnd()) + 65))))
Randomize()
objStringBuilder.Append(Chr(CInt(Int((25 * Rnd()) + 65))))
Randomize()
objStringBuilder.Append(Chr(CInt(Int((25 * Rnd()) + 65))))
Randomize()
objStringBuilder.Append(Chr(CInt(Int((25 * Rnd()) + 65))))
Randomize()
objStringBuilder.Append(Chr(CInt(Int((25 * Rnd()) + 65))))
The strange thing is the results are not really random, and they
follow some kind of strange patterns...
I obtain strings like (Pattern 1 = Repeat Sequences):
WUPYUP, ECVGCW, QOJSOJ, and similar.
One other pattern, (Pattern2 = Letters in Vicinity), which shows up
extremely frequently seems to be in results like NLFPKG, IGBLGC,
KICMHD, etc. Note that:
Letter1 is "NEAR" Letter4,
Letter2 is "NEAR" Letter4,
Letter3 is "NEAR" Letter5
Actually, Pattern1 is a particular case of Pattern2...
Hmmmmmm... I am forgetting something ?
Thanks a lot.
