Code:
Private Sub CheckButton_Click(sender As Object, e As EventArgs) Handles CheckButton.Click
        For i = 1 To 58112          '58112 is the amount of words im checking against 
            If LCase(word) = LCase(arrwords(i)) Then
                MsgBox("it is a word")
                totalscore = totalscore + checkscore 
                ListWM.Items.Add(word)   'words made so far
            End If
        Next

        TextScore.Text = totalscore
        ResetButton.PerformClick()
end sub

So i am making a boggle type game where you have 7 tiles and you have to make as many words as you can. I can check against the words in the dictionary just fine.
I need help making an array of Words Made so far and making sure the user doesnt use the same word twice. I am kinda new to VB.Net and i dont know hot to convert a list to an array
