Sech string in big file

2 posts in this topic

Hi all, I have a big text file ~50 Mb and I need a quick string find... (check if string exists in file)

right now my method takes over 7-8 seconds to check all file. Can any one suggest how to make it work faster ?

Any ideas ? :)

$sSearched = 'test lineeeeeef' ;text to find

$hz = 0
$sText = FileRead('XXX.inf')

$aLines = StringSplit($sText, @CRLF, 1)

For $i = 1 To $aLines[0] Step +1
    If StringInStr($aLines[$i], $sSearched) Then $hz = 1
    ;MsgBox(0, 'Found', 'Line ' & $i & @CRLF & $aLines[$i])
Next

if $hz == 1 Then MsgBox(0,"xxx","FOUND !!!")
MsgBox(0,"ddd","done")

// and sorry for my English...

Firstly, you don't need Step + 1 as this is default of a For loop. Secondly, because it appears you only want to find the first instance why not use this?

Local $sSearched = 'test lineeeeeef' ; Text to find
If StringInStr(FileRead('XXX.inf'), $sSearched, 2) Then
    MsgBox(4096, '', 'Found')
Else
    MsgBox(4096, '', 'NOT Found')
EndIf
