How to remove Case sensetive from this ?

[tonycst]

$SearchFor = StringRegExpReplace($SearchInput, "([\\\.\*\+\(\)\?\^\$\|\{\}\[\]])", "\\$1")
$res = StringRegExp($source, "(?im)^.*" & $SearchFor & ".*$", 3)

I dont get this part of code and dont know how to remove case sensetive comparing.

Can you guys help or explane ?

I looked into help file and found that (?i) is supose to be it, but removing it returns no search results at all

try stringinstr it searches for occurrences depeding on the option you set... Then replace the strings with stringreplace, just play around a bit... you'll eventually figure it out.

tonycst,

Welcome to the Autoit forum.

RegExes are not the easiest subject to choose as your first post!

What are you trying to do with the code you have at the moment? It looks as if the StringRegExpReplace line is escaping all action characters within a RegEx so that the pattern for the StringRegExp line can use the result as a pattern.

But removing the case sentitivity should be as simple as replacing the (?im) with (?m). However, as I am not sure quite what you are doing I am not sure that is the correct solution.

Well what i am trying to do is search text document containing large text data for a string.

This example i pulled out of this forum a while ago was great but it was set to be case sensetive.

And because i never worked with these functions before, i didnt know how to make it not to be case sensetive.

Maybe the case sensetivity doesnt even come from here, but i dont see any other place in the script where string matching takes place.

Text file is large with over 44.500 lines of text, so having "stringinstring" and a ton of if statements per line would slow down search from miliseconds to hours.

Here is a piece of a loop in which searching and matching is done. Sorry i should have posted this befor asking.

If $msg = $SearchButton Then
  $source = "textfile.txt"
  If GUICtrlRead ($TextBook) = "No TextBook Found" Then
   $AskToGoToDownloadPage = MsgBox(32,"Bible Error","                               No TextBook Found." &  @CRLF & "Please download TextBook file first by clicking link on the right.",'',$MainGUI)
  EndIf
  $Found = 0
  GUICtrlSetData ($SearchButton,"Stop !")
  $SearchInput = GUICtrlRead($Input)
  _GUICtrlListView_DeleteAllItems(GUICtrlGetHandle($ListView))
  _GUICtrlStatusBar_SetText ($StatusBar,"Searching")
  $SearchFor = StringRegExpReplace($SearchInput, "([.*+()?^$|{}[]])", "$1")
  $res = StringRegExp($source, "(?im).*" & $SearchFor & ".*$", 3)
  If Not @error Then
   For $line In $res
    $Loopmsg = GUIGetMsg()
    If $Loopmsg = $SearchButton Then
     GUICtrlSetData ($SearchButton,"Go !")
     ExitLoop
    EndIf
    $NewLine = StringTrimLeft ($line,StringInStr($line,"*")) ;returns text without junk such as: T=1,C=10* Actual book text line continues here
    GUICtrlCreateListViewItem($NewLine, $ListView)
    Assign ("Found",$Found+1)
   Next
   ResizeCollumns()
  EndIf
  GUICtrlSetData ($SearchButton,"Go !")
  _GUICtrlStatusBar_SetText ($StatusBar,"Found " & $Found & " instances")
EndIf

Am not sure (in this case) how does "For $line in $res" work, maybe this is where i need to study ?

In anycase, i tried removing the "i" from "?im" but it didnt help.

I am trying to find text such as "it was a Tomato" by searching for "it was a tomato" but i get no search results unless i give it a capitol T

So am not sure what defins the search pattern in these functions since they dont make sence at all. Like i said, i found them here and used them without knowing exactly how they work, as long as they get the job i didnt care much untill now.
