To make the seed as random as I can, I use the current "totalseconds"
as the seed value:
Dim rn As New Random
Dim d As Date
d = New Date
rn.Seed = d.TotalSeconds
d = Nil
It's an extra call, but the resulting "randomness" is much less
predictable.
To refresh the seed and start a new sequence, just get a new date to
update the TotalSeconds and then reset the seed to this new
d.TotalSeconds value. However, you really should only set the seed
once and then let the nature of the randomizer do the rest.
