StringReplace wont work for binaries?

[rover]

Hi,

Is there a way to do Hex / Binary editing now that StringReplace will no longer work on binaries?

The first code example worked on older versions of AutoIt before the Unicode? upgrade.

The second example wont overwrite the 3 digits in the file string stored in the variable $filedat

I have made the changes in the code for version 3.2.4.x

Currently running v3.2.4.9

;v3.2.x.x - This code would overwrite the 3 digits

Local $newg2 = 090, $oldg2 = 130

$File = @WorkingDir & "\CPDG520P.DAT" ; 12Kb binary EEPROM data file
$rdFile = FileOpen($File, 0) ; Open in READ mode
$FileDat = FileRead($rdFile) ; Read entire file to variable
$FileDat = StringReplace($FileDat, 9236, $newg2, 1, 0) ; replace 3 digit number at offset 9236 with 090
MsgBox(0, "# of Replacements", @extended)
FileClose($rdFile)

$rdFile = FileOpen($File, 2) ; Open in WRITE mode (erase previous contents)
MsgBox(0, "Writing to CPDG520P.DAT", "At Offset: 9236: " & $oldg2 & "  Replacing with:  " & $newg2)
FileWrite($rdFile, $FileDat)
FileClose($rdFile)

;-------------------------------------------------------

;v3.2.4.x (Using v3.2.4.9)  - This code wont overwrite the 3 digits and StringReplace @extended returns 0

Local $newg2 = 090, $oldg2 = 130

$File = @WorkingDir & "\CPDG520P.DAT" ; 12Kb binary EEPROM data file
$rdFile = FileOpen($File, 16) ; Open in Binary READ mode
$Filedat = FileRead($rdFile)  ; Read entire file to variable
$Filedat = BinaryToString($Filedat)
$FileDat = StringReplace($Filedat, 9236, $newG2, 1, 0) ; replace 3 digit number at offset 9236 with 090
MsgBox(0, "# of Replacements", @extended)
FileClose($rdFile)

$rdFile = FileOpen($File, 18) ; Open in WRITE mode (erase previous contents)
$Filedat = StringToBinary($Filedat)
FileWrite($rdFile, $Filedat)
FileClose($rdFile)

O.K. I finally got it to work, but with several problems.

@extended isn't returning replacement count from StringReplace, it always returns 0

though it is replacing the string (3 digits)

had problem with leading zero number eg. 070

StringReplace would only write 2 digits without leading zero

(using range of 050 to 180)

attempting to concatenate quotes didn't work eg, chr(148) or chr(34)

"chr(34) & $newg2 & chr(34)"

StringReplace with quotes around number with leading zero worked as it had in my original test code,

that's one thing i changed once i added the routine for getting the value from the slider,

before that i had hard coded the value (in quotes) in the StringReplace line for testing.

This works

; value in file 130
$FileDat = StringReplace($Filedat, 9236, '090', 1,0) ; replace 3 digit number at offset 9236 with 090
;result = 090
