Your requirements are not clearly defined, we have to guess what you exactly want to do
Assumption : you want to remove 4 hex digits after each group of 2 digits ('20 ')

$sHexToReplace = "0x200000200100200200200300200400200500200600200700200800200900201000202000203000204000205000206000207000208000209000200A00200B00200C00200D00200E00200F0020A00020B00020C00020D00020E00020F000"

$sHexToReplace = StringTrimLeft($sHexToReplace, 2)
$res = "0x" & StringRegExpReplace($sHexToReplace, '[[:xdigit:]]{2}\K[[:xdigit:]]{4}', "")
msgbox(0,"", $res)

Thank mikell very much!

I  replace the hex string (2 characters) in hex code
If using stringreplace it replaces unlike hex editor, so it did damage hex code.

If split hex string with two characters each can be successfully replaced but slow?
or can be search under the even number and next number.

That was my thought, it really is crap.

You need to pair 2 characters and test those:

eg:  when replacing 00 in 2000 with xx you want to compare character 1 with a length of 2 (20) and then character 3 with a length of 2.(00) ending up with 20xx.

You are now replacing the first 00 combo which are 2000 ending with 2xx0.

I think you dont need to use so much regexp, loop and checking...

Local $sString="0x200000200100200200200300200400200500200600200700200800200900201000202000203000204000205000206000207000208000209000200A00200B00200C00200D00200E00200F0020A00020B00020C00020D00020E00020F000"
ConsoleWrite("+ IN: " & $sString & @CRLF)
$sString=BinaryToString($sString)
$sString=StringReplace($sString,Chr(0x00),"")
ConsoleWrite("!OUT: " & StringToBinary($sString) & @CRLF & @CRLF)

If you want to replace some binary inside a file then use that function to write another function. Like this maybe:

Func FileBinaryReplace($sFile, $bSearch, $bReplace, $iOccurence = 0)
    Local $hFile = FileOpen($sFile, 17) ; binary mode, read, write
    FileSetPos($hFile, 0, 0)
    Local $bBinary = FileRead($hFile)
    FileSetPos($hFile, 0, 0)
    FileWrite($hFile, BinaryReplace($bBinary, $bSearch, $bReplace, $iOccurence))
    FileClose($hFile)
EndFunc

Add some error checking and you are done.

^^ Add "0x".

$sFileContent = BinaryReplace($sFileContent, "0x" & $sBadString[$s], "")
;...
FileBinaryReplace($TestFile, "0x" & $sBadString[$s], "")

 

 

 

Not working:
 

FileBinaryReplace($TestFile, "0x" &$sBadString[$s], "")

 

I changed a few things,and it worked!

Func BinaryReplace($bBinary, $bSearch, $bReplace, $iOccurence = 0)
    If (StringLeft($bSearch, 2) <> "0x") And ($bSearch <> "") Then $bSearch = "0x" & $bSearch
    If (StringLeft($bReplace, 2) <> "0x") And ($bReplace <> "") Then $bReplace = "0x" & $bReplace
    Local $sString = StringReplace(BinaryToString($bBinary), BinaryToString($bSearch), BinaryToString($bReplace), $iOccurence, 1)
    Return SetError(@error, @extended, Binary($sString))
EndFunc   ;==>BinaryReplace

Func FileBinaryReplace($sFile, $bSearch, $bReplace, $iOccurence = 0)
    Local $hFileOpen = FileOpen($sFile, 16)
    Local $sFileContent = FileRead($hFileOpen)
    FileClose($hFileOpen)
    $hFileOpen = FileOpen($TestFile, 2 + 16)
    FileWrite($hFileOpen, Binary(BinaryReplace($sFileContent, $bSearch, $bReplace, $iOccurence)))
    FileClose($hFileOpen)
EndFunc   ;==>FileBinaryReplace

 

But it only supports standard characters!

 

Global $TestData = "0x00010203040506070811121415161718192131010"

ConsoleWrite( BinaryReplace($TestData, "010" , "888")& @CRLF)
;~ ConsoleWrite( _BinaryReplace($TestData, "010" , "888")& @CRLF)

It's like "0x010?" but working for "0x010"! :P



Although there 3GB RAM but trouble appeared when working with large files over 40MB! :mad:

Has 4:00 AM, I need to sleep! :yawn::yawn:
Will research this problem later!
