Default How to detect excess rows in txt or csv files before opening?

Windows XP Pro SP2
Excel 2002 SP3

I am trying to detect if a txt or csv file has more than 65,536 lines before
opening it. I've written this little tidbit for testing:

Sub testme()

Dim data As String
Dim fname As String
Dim c As Long

fname = "C:\911\_temp\test_data1.csv"

Open fname For Input As #1
c = 0
Do Until EOF(1)
Line Input #1, data
c = c + 1
Loop
Close #1

MsgBox c

End Sub


This works fine on files with less than or equal to 65,536 lines of data.
If I try the same code on a file with 65,537 lines or more then Excel locks
up.

Is there any way around this? Why is Excel crashing? Should I bite the
bullet and learn to use Access?

Any and all suggestions welcome. Thanks!
