Name
Randomize Procedure
Class
Microsoft.VisualBasic.VBMath
Syntax
Randomize([number
])
-
number
(optional; Object or any valid numeric expression) A number used to initialize the random-number generator
Description
Initializes the random-number generator
Rules at a Glance
Randomize uses
number
as a new seed value to initialize the random-number generator used by the Rnd function. The seed value is an initial value that is used to generate a sequence of pseudorandom numbers.If you do not pass
number
to the Randomize procedure, the value of the system timer will be used as the new seed value.Repeatedly passing the same number to Randomize does not cause Rnd to repeat the same sequence of random numbers.
Programming Tips and Gotchas
If you need to repeat a sequence of random numbers, you should call the Rnd function with a negative number as an argument immediately prior to using Randomize with any numeric argument.
