Display the sentences in textbox.

Example:

The machine's IP address is "10.12.13.24".
I love this IP.

Sample code Code:
-------------------
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
//* Show the sentences in the textbox *//
Private Sub cmdShow_Click()

Dim shtDVD As Worksheet
Dim strName As String

Set shtDVD = Application.ActiveWorkbook.Worksheets(1)

txtShow.Text = "The machine's IP address is "10.12.13.24"." &
vbNewLine & vbNewLine & "I love this IP."

End Sub
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
Result:
-----------

(i) Got Error. If I replaced the "10.12.12.24" to 10.12.13.24 then it
is ok....May I know how can I display "10.12.13.24" instead of
10.12.13.24.

(ii) May I know how can I display my sentences as above without the
vbnewline because if I'm using vbnewline the code will proceed long
and messy:-
May I write my code as below?
