Idea for a new String-UDF

Recommended Posts

Hi guys,

i've got a little problem and i think an UDF would be a good idea to solve it :dance: But, coz of my poor au3skills I cant create one. But maybe someones else can try it, thanks in advance for everyone who's tryin'.


I've got a very Huge File which I open with FileOpen(). It has got like 803 lines. It's a HTML-File. There are some important lines which i wanna use with FileReadLine(). The problem is, i dunno in what line it is. But i know whats written in these lines!


An UDF which can find a String in a FileOpen-String and return the line.

If someone has a better idea, please tell me how u would solve this problem.

Thx in advance, greetings :whistle:

It's pretty easy.

$filename = "C:\boot.ini"
$searchfor = "windows"
$file = FileRead($filename, FileGetSize($filename))
$lines = StringSplit($file, @CRLF, 1)
For $i = 1 to $lines[0]
    If StringInStr($lines[$i], $searchfor) Then
        MsgBox(0,"","Line number: " & $i)
