How to make Randomize function to randomize the timers intervals?

I can’t figure out the code for vb.net that would randomize the interval of a certain timer. For each a = a + 1, there would be a different开发者_高级运维 interval, and for each a = 1, a = 2, a = 3 etc. there would be a different text that will be shown on a label.

If you know how to make it possible, please help. Thank you.

i might not quite understand something like this

Dim arrLbls(3) As Label
'an array with 4 elements of type label' 'populating the array'

arrLbls(0) = Label1
arrLbls(1) = Label2
arrLbls(2) = Label3
arrLbls(3) = Label4

'loops trought array'

For i As Int16 = 0 To arrLbls.Length - 1
    arrLbls(i).Text = "Label from the array " & i + 1
Next

`

Make use of the Random class

   Public Function RandomNumber(ByVal MaxNumber As Integer, _
    Optional ByVal MinNumber As Integer = 0) As Integer

      'initialize random number generator
        Dim r As New Random(System.DateTime.Now.Millisecond)

      'if passed incorrect arguments, swap them
        'can also throw exception or return 0

        If MinNumber > MaxNumber Then
            Dim t As Integer = MinNumber
            MinNumber = MaxNumber
            MaxNumber = t
        End If

        Return r.Next(MinNumber, MaxNumber)

    End Function
