Replace a line in a text file

I have a text file that I need to replace the 3rd line of data in..

What is the best way to do this?

For example:

I have c:\testfile.txt

It reads:

line 1
line 2
line 3
line 4

I want to change it to read:

line 1
line 2
New line 3
line 4

How can I do that?

Thanks!

Code:

---

Dim iCount As Integer
Dim TmpFile As String

Open "myfile.txt" For Input As #1
    Do Until EOF(1)
        Line Input #1, tmp
        iCount = iCount + 1
        If iCount = 3 Then tmp = "NewLineToBePrinted"
        TmpFile = TmpFile & tmp & vbCrLf
    Loop
Close #1

Open "myfile.txt" For Output As #1
Print #1, TmpFile
Close #1
