Select word from list and display?

How do you randomly select a word from a list like below:

dog
cat
mouse
goldfish
pig
cow

and display it in a text box when a button is clicked, but where one word will not appear more than once each time the program is run? So, for example,

1st click: pig
2nd click: mouse
3rd click: dog
4th click: cow
etc. But NOT

1st click: pig
2nd click: dog
3rd click: mouse
4th click: pig

Any ideas? :)

You could do something like this

Code:

---

Public Class Form1
    Dim randomList As New List(Of String)

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        randomList.Add("pig")
        randomList.Add("dog")
        randomList.Add("cat")
        randomList.Add("mouse")
        randomList.Add("goldfish")
    End Sub

    Private Sub TextBox1_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles TextBox1.MouseClick
        Dim randomNumber As Integer = makeRandom()
        If Not randomList.Count = 0 Then

            Me.TextBox1.Text = randomList(makeRandom)
            randomList.RemoveAt(makeRandom)

        Else
            Me.TextBox1.Text = " No Items to show"
        End If
    End Sub

    Private Function makeRandom() As Integer
        Dim randomGenerator As System.Random = New System.Random()
        Return randomGenerator.Next(0, randomList.Count)
    End Function

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        If randomList.Count > 0 Then
            randomList.RemoveRange(0, randomList.Count)

        End If
        TextBox1.Text = ""
        randomList.Add("pig")
        randomList.Add("dog")
        randomList.Add("cat")
        randomList.Add("mouse")
        randomList.Add("goldfish")

    End Sub
End Class

Thanks. Exactly what I needed. :)
