    Private Sub txtFileName_TextChanged(sender As Object, e As EventArgs) Handles txtFileName.TextChanged
      If e.KeyChar = ChrW(Keys.Enter) Then
        Dim FileNameTyped As New FileInfo(Me.txtFileName.Text)
        If FileNameTyped.Exists Then
          Call ShowFileContents(Me.txtFileName.Text)
