I think this is what you want:

Public Class Form1
    Dim i As String
    Dim x As Object
    Dim phrase As String
    Dim num As Integer
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        i = TextBox1.Text
        For Each x In i
            num = x.ToString()
            Select Case num
                Case 1
                    phrase += "R"
                Case 2
                    phrase += "A"
                Case 3
                    phrase += "V"
                Case 4
                    phrase += "I"
                Case 5
                    phrase += "N"
                Case 6
                    phrase += "D"
                Case 7
                    phrase += "R"
                Case 8
                    phrase += "A"
                Case 9
                    phrase += "N"
                Case 0
                    phrase += "M"
                Case Else
                    phrase += "O"
            End Select
        Next
        TextBox2.Text = phrase
    End Sub
End Class
