Randomize Method

The Randomize method creates a starting value for the random number generator. It does not return a value. If you do not specify a value for the number argument, then it uses the Get Seconds method to reset the random number generator.

Format

Randomize [number]

The following table describes the arguments that you can use with this method.

Example

The following example uses the Randomize method and the Get Random Number method to create a random string of characters. The second For Next loop slows down processing in the first For Next loop so that the Timer method can seed the Randomize method with a new value each time the loop runs:

Sub Button_Click
   Dim x As Integer, y As Integer
   Dim str1 As String, str2 As String
   Dim letter As String
   Dim randomvalue
   Dim upper, lower
   Dim msgtext
   upper = Asc("z")
   lower = Asc("a")
   newline = Chr(10)
   Randomize
   For x = 1 to 26
      randomvalue = Int(((upper - (lower + 1)) * Rnd) + lower)
      letter = Chr(randomvalue)
      str1 = str1 & letter
      For y = 1 to 1500
      Next y
   Next x
      msgtext = str1
End Sub
