Maybe there are some File Att

Answer 1

As Guffa and Jason said, there is no way to get the lines other than reading to the end.

To solve your problem differently:

If you are interested only in the percentage display you COULD try to acummulate that value from the total file size and the line you are currently at. You need to apply some voodoo tricks there to get the actual bytes read (like say, you have read to line 10, and a total of 200 bytes or whatever) and the file size is 400bytes. You could probably guess that you are at 50%, without giving needing to know a total line number.

Thats just some random numbers there, btw.
