replace string from file

[jorgeng]

I want to replace a word in a string read from file but can't get it to work, can someone see what's wrong? $trade_original is empty after replace...

#Include <File.au3>

        $file_Omx_Wampa_PHP_Mangold = FileOpen("C:\Filer\Rankor System\Omx_Wampa_Trades_PHP_Mangold.txt", 0)

;       Check if file opened for reading OK
        If $file_Omx_Wampa_PHP_Mangold = -1 Then
            MsgBox(0, "Error", "Unable to open file Omx_Wampa_PHP_Mangold.")
            Exit
        EndIf

;       Read in lines of text until the EOF is reached
        While 1
            $sData = FileReadLine($file_Omx_Wampa_PHP_Mangold)
            If @error = -1 Then ExitLoop
            MsgBox(0, "Line read:", $sData)
        Wend

;       $sData = '10:16 ORDER "sl) Omx Wampa - Entry Short - Kl.10 - Röd - Okrypterat OMXS300I" kurs 1050.0000$'
        $trade_original = StringReplace($sData, "Entry", "Exit")

        ConsoleWrite("1=" & $trade_original & @CRLF)

hey, I need the answer for that too. Actually I want to modify some strings in a very big file size, directly in the memory. I don't want to use heavy method like FileWrite and overwrite.

Try _ReplaceStringInFile function

I just want a simple replace of string since i shall delete file and do filewrite with new content...

It seems that it has to be simple text in

StringReplace($sData

not accepting $sData

        ConsoleWrite("1=" & $trade_original & @CRLF)

The way you're reading your file in means that the only thing that $sData is going to contain is the last line of the file and nothing else. If you want $sData to contain the whole file's contents then you need to either write it like this:

While 1
            $sData &= FileReadLine($file_Omx_Wampa_PHP_Mangold) ;<===Notice the "&" before the "="
            If @error = -1 Then ExitLoop
            MsgBox(0, "Line read:", $sData)
Wend

Or like this without the While..Wend:

$sData = FileRead($file_Omx_Wampa_PHP_Mangold)
        MsgBox(0, "Line read:", $sData)

Try _ReplaceStringInFile function

Thx. It only allow text editing I guess. Is there any way to binary edit it or hex edit it?
