i want to make program for a quiz.
i create the questions is an array,
and i want that questions start at random, and never be shown again.

dim question() as String = {"OTOMATIS MENURUT KERJA MESIN", "TIDAK MENEPATI JANJI", "YANG UTAMA", "TEMPAT TINGGAL KEPALA NEGARA", "PENGURUS RUMAH SAKIT",
                                  "SUDAH PUAS MAKAN", "NEGARA INDUSTRI DI EROPA", "WILAYAH KEPULAUAN INDONESIA", "ILMU HUBUNGAN TIMBAL BALIK ANTARA MAKHLUK HIDUP DENGAN LINGKUNGANNYA",
                                    "SIHIR(INGGRIS)"}

and after that what i have to do??

Here is an algorithm.

To shuffle an array a of n elements:

for i from n − 1 downto 1 do
       j ← random integer with 0 ≤ j ≤ i
       exchange a[j] and a[i]

i still not understand, can i get more detail?

        Dim rnd As New Random
        Dim index1, index2 As Integer
        Dim tmp As String

        For cnd As Integer = 1 To 5
            'Obtain two random numbers betwee 0 to question.Length-1
            index1 = rnd.Next(question.Length)
            index2 = rnd.Next(question.Length)

            'Swap string
            tmp = question(index1)
            question(index1) = question(index2)
            question(index2) = tmp
        Next

thanks alot my friend
and because it's random some index shown again.
thanks again
