Help with a function

[Olsenius]

I'm working on a little utility to edit some .htm files from a game i play.

The numbers on the page are images with random name. I have isolated the img names. And made this function to give me the right number.

$number = finnNr("adfmd.gif")
MsgBox(0, "test", $number)
Exit

Func finnNr($search)
     $file = FileOpen("img.txt",1)
     While 1
        $line = FileReadLine($file, 1)
        If $search == $line  Then
            Return FileReadLine($file, 1)
        EndIf
        If @error Then ExitLoop
     WEnd
     Return "NA"
EndFunc

the start of img.txt is:

adfmd.gif
5
aepvl.gif
8
aidph.gif
4
amljf.gif
9
asnfd.gif
8

As i see this shuld return "5", but it only give me "NA". I cant see what i'm doing wrong.

If you see whats wrong or know a better way to do it please let me know.

Thanks.

Wrong FileOpen parameter. 1 is write mode. You want to read, which is parameter 0.

Mode (read or write) to open the file in.
  0 = Read mode
  1 = Write mode (append to end of file)
  2 = Write mode (erase previous contents)
  4 = Read raw mode

Thank you! That did the trick.

Added a counter and changed to readmode and it works like a charm.

two questions for you:

1.) What does FileOpen() when you call it with option 1?

2.) What does FileReadLine() when you call it with a second parameter?

The answer to those questions will make your script work.

EDIT: Damn... too late ...
