write a windows application that allows the user to enter
a seven-digit number in a multiple line textbox
when the user clicks the generate words button.

    Inherits System.Windows.Forms.Form

    Public Numbers(7, 3) As String
    Public Phonenumber As Integer
    Public output As String

        ' Dim Numbers(7, 3) As String

        Numbers(0, 0) = "A" '2
        Numbers(0, 1) = "B" '2

            x += 1
        Next

        Dim word As String = ""

        'creates only 3 words out of the phonenumber

So ... whats the problem?

[perumar]

Thanks

you never assign "output"
output = PhoneNumberWordsListBox.Text in your code means Nothing = nothing

try this:

For i As Integer = 0 To 2
                Dim word As String = ""
                For Each s As String In phoneNumber
                    word = word & DirectCast(arrayL.Item(CInt(s)), Char())(i).ToString
                Next
                PhoneNumberWordsListBox.AppendText(word & vbNewLine)
            Next
