non repeating words

I can write a program that picks random words... but WITHOUT REPEATING ANY OF THEM? How do I do this?
i.e. cat
dog
zebra
elephant
horse
bear
cow

Thanks in advance

Here is something that I'm sure can be written much easier, but it should work for now (it involves a CommandButton and ListBox)

Code:

---

Private Sub Command1_Click()
    Dim stWord(1 To 7)  As String
    Dim intWord As Integer
    Dim I As Integer
   
    Randomize Timer
   
    stWord(1) = "Cat"
    stWord(2) = "Dog"
    stWord(3) = "Zebra"
    stWord(4) = "Elephant"
    stWord(5) = "Horse"
    stWord(6) = "Bear"
    stWord(7) = "Cow"
   
    intWord = Int((7 - 1 + 1) * Rnd + 1)
    For I = 0 To List1.ListCount
        If List1.List(I) = stWord(intWord) Then
            MsgBox "Word already chosen " & stWord(intWord)
            Exit For
        ElseIf I = List1.ListCount Then
            List1.AddItem stWord(intWord)
            MsgBox "Word I chose: " & stWord(intWord)
        End If
    Next I
End Sub

General idea is to add the word to the listbox and then check if it is in there.

You will hear a lot about it.

See MyPost for a method that uses a collection that would be faster.

I copied and pasted your codes, and they worked great! But, I don't want this to get nvolved a listbox. I want a textbox. Thanks all of your help though!

I know a little bit (a very little bit) about using API. I ran the program using the below code... it was very good!!

Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Private Const LB_FINDSTRINGEXACT = &H1A2

But, how do you use Prviate Declate Function SendMessage Lib ..... and use a textbox, not listbox?

Thanks!
