...TO HEX

[CoolBreeze]

Hi, guys! [sorry for bad ENG.]

#Include <EditConstants.au3>
#Include <WinAPI.au3>
#Include <WindowsConstants.au3>
    Global $sFile, $hFile, $iSize, $sData, $tData, $iRead
$sFile = @SCRIPTDir & '\TEST.rar'
$iSize = FileGetSize($sFile)
$tData = DllStructCreate('byte[' & $iSize & ']')
$hFile = _WinAPI_CreateFile($sFile, 2, 2, 2)
_WinAPI_ReadFile($hFile, DllStructGetPtr($tData), $iSize, $iRead)
_WinAPI_CloseHandle($hFile)
$sData = ''
    For $i = 1 To $iSize
        $sData &= Hex(DllStructGetData($tData, 1, $i), 2)
        If Mod($i, 16) = 0 Then
            $sData &= @CRLF
        Else
            $sData &= ' '
        EndIf
    Next
$sData = StringTrimRight($sData, 2)
FileWrite("hextext.txt", $sData)

I wonna write large text file in "hex"

from file whose size is <100Mb

I`am tried...without success -> low memory

BUT. "HHD_Hex_Editor" opening that large rar file in 5.sec and exporting for a short time, similar "hextext.txt"

Some help?

BoRisk,

I hope this does what you want:

; Open the file and read as bytes
$hFile = FileOpen("test.rar", 16)
$sByteContent = FileRead($hFile)
FileClose($hFile)

; Convert the bytes to hex and remove the leading 0x
$sHexContent = Stringtrimleft(StringToBinary($sByteContent), 2)

; Write the file
$hFile = FileOpen("hextext.txt", 2)
FileWrite($hFile, $sHexContent)
FileClose($hFile)

Please come back if not.

I am here again :P/First, Thank you for the attempt to help/I have appended two screenshot...First is the Error, i talked about that in the first postThe same is happening with my script. But its work with file smaller than ~~100KbSecond scrs. shows what I thought. Your hex_content compared with my._WinAPI, <-- There lies the secret.I would like to solve this.

BoRisk,

First problem: I have no idea why your code produces that error on your machine. Does mine?

Second problem: My fault, sorry. I removed the leading 0x and converted the binary - I only needed to do one or the other. Try this code:

; Open the file and read as bytes
$hFile = FileOpen("test.rar", 16)
$sByteContent = FileRead($hFile)
FileClose($hFile)

; Remove leading 0x
$sHexContent = StringTrimLeft($sByteContent, 2)

; Write the file
$hFile = FileOpen("hextext.txt", 2)
FileWrite($hFile, $sHexContent)
FileClose($hFile)

Again the same problem. Error allocating memory, your code-my code similarly

I have idea. I'm going to try on another pc,

Please test my script with file of 100Mb,

If work, please tell me how much time he should, and what your machine configuration..

Tomorrow I will tell if it works on another machine.

@Melba23, Hex() is to be used for that.

As for memory problem, that's perfectly normal. BoRisk you are storing 100MB into a variable. Don't do that. That goes directly into RAM.

Your HHD_Hex_Editor is using simple trick. It reads just enough bytes you can see at time, and when you scroll that control it moves file pointer forward or back and reads at that position.

[CoolBreeze]

You right. Thats the trick.

OK, I changed the plan.

I will try to view file in hex as that editor.

I have no idea how to open in part, and show in GUI EDIT BOX, the highest possible rows

In any case thank!
