Correspondance -- or there abouts

I have opened a file using FileOpen, and i was wondering whether or not the Loc() function which returns current read/write position corresponds to the line its on, so if its on 4 then thats line 4??
Or have i got it completely wrong? if so how do i get data on a certain line??

Cheers,

It is documented here:

http://msdn2.microsoft.com/en-us/library/5tb5ex52(VS.80).aspx

You are correct though in your assumption, from the MSDN:
"Returns a Long value specifying the current read/write position within an open file."

Sorry my brain is dead today, i still dont get how to get the line number
Is there someway of putting it into an array so:

Code:

Dim sLines() As String
Dim sCurrentLine As String
Dim iLineNum As Integer = 0

Do until EOF(1)
    sLine = LineInput(i)
    iLineNum = iLineNum + 1
Loop

sCurrentLine = sLine(iLineNum)

Cheers,

Oh, i know how to count the number lines in a file, but its just the line number im having trouble with but i think i have got it sorted!
What i've done is in the file i have put numbers at the front of each line obviously corresponding to the line number then i have just got code to loop (enumerate?) through and stop when it reachs the line i want!

Thanks all the same,

The way I would approach this is that I would start at the beginning of the file, and move through it 1 char at a time, tallying the characters that generate new lines.

(Of course, you cna do the same thing reading the file into a string and searching the string... mech less disc drive intensive, faster, smarter, etc.)
