reading binary file to array

Recommended Posts

FMS

Hello,

I'm trying to read a binary file to an array but couln't get it to work.
Also I coul not find any help in the forum around this subject whish was helpfull.

Is there any way it could be done?

I tried a lot of ways but maybe somebody know's the right way?

#AutoIt3Wrapper_Au3Check_Parameters=-d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6 -w 7
#include <File.au3>
#include <Array.au3>
#include <AutoItConstants.au3>

Local $in=FileOpen("TEST_labels.idx1-ubyte",16) ; 16+0=Read binary
Local $data = FileRead($in)
Local $FileArray = BinaryToString($data,4)
;~ $FileArray = StringSplit($BinarydData, @CRLF, 1+2)
;~ Local $FileArray = StringRegExp($BinarydData, "[^\r\n]+", 3)
FileClose($in)
_ArrayDisplay($FileArray,"$FileArray","",32)
MsgBox($MB_SYSTEMMODAL, "", "$FileArray = " & $FileArray )

 

TEST_labels.idx1-ubyte

What do you expect the array to look like? Also, BinaryToString returns a string, not an array.

You can take something like this script and modify to your needs.

#include <Constants.au3>
#include <Array.au3>
#include <StringConstants.au3>

Example()

Func Example()
    ; Create a random string of lower-case ASCII characters.
    Local $sString = ''
    For $i = 1 To 1000
        $sString &= Chr(Random(97, 122, 1))
    Next

    ; Split the string to 2 characters per line.
    ChrsPerLine($sString, 2)
    $array = StringSplit($sString, @CRLF, $STR_ENTIRESPLIT)

    ; Display the split string.
    _ArrayDisplay($array)
EndFunc   ;==>Example

Func ChrsPerLine(ByRef $sData, $iChrsPerLine = 4096) ; Default is 4096 characters per line.
    $iChrsPerLine = Int($iChrsPerLine)
    If $iChrsPerLine <= 0 Then $iChrsPerLine = 4096

    Local $sTemp = ''
    While StringLen($sData) > $iChrsPerLine
        $sTemp &= StringLeft($sData, $iChrsPerLine) & @CRLF
        $sData = StringTrimLeft($sData, $iChrsPerLine)
    WEnd

    If StringLen($sData) Then
        $sTemp &= $sData & @CRLF
    EndIf
    $sData = $sTemp
EndFunc   ;==>ChrsPerLine

*Note: script slightly modified from this post.

That wouldn't work in his case, the "numbers" are in Hex..

if you need BinaryArray to store in SQL or to work with some PDF API you should look for this :

FileOpen(...$FO_BINARY....
FileRead(..
FileClose(...

FMS,

I inspected your file with notepad++ and don't find any "hex" numbers, just decimal.  Unless it is just a coincidence the the 10,007 numbers do not contain A-F.

Did you try my code?

Try this...

#include <Array.au3>

$sfile = FileRead(@ScriptDir & '\TEST_labels.idx1-ubyte')

Local $afile = StringRegExp($sfile, '.{2}', 3)

local $afile2[ubound($afile)][2]

for $1 = 0 to ubound($afile) - 1
    $afile2[$1][0] = $afile[$1]
    $afile2[$1][1] = hex($afile[$1],4)
Next

_ArrayDisplay($afile2)

      Hi Virtual People,
      My array works perfectly fine. However, what is the best practice if the line in the array doesn't have the correct amount of columns and if I can add a placeholder?

       
      For $count = 1 To _FileCountLines($FileRead1) Step 1 $string = FileReadLine($FileRead1, $count) $input = StringSplit($string, ",", 1) $value1 = $input[1] $value2 = $input[2] $value3 = $input[3] _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value2, "A1") _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value1, "B1") _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value3, "C1") Next

      hi all,
      reviewing the forum, this thread is applicable: 
       
       
      I wanted to know if there is now a better way to do this?
      In essence, I load a tab delimited txt file into an array (works well). I used tab, as some fields in the original csv contains commas.
      However, I needed autoit to manipulate this array, and output it as a csv.
      IF my array contains items with a comma, without double quotes around the field, then how best do I get a csv out of this?
      My current workaround is to filewritefromarray tab delimited, then open it in excel and save as a csv. I will need to check this to see how the address fields behave that contain a comma.
       
      Any thoughts would be appreciated.

      Hi All,

      I would like to know how you would take a FileLineRead and insert it into an array which then inserts it into Excel?
      One thing to know is the files content is broken up, so I only use half of the content within $FileRead1.
      So its imperative that the $value1, $value2, etc variables be used. 
      Code below:
      $FileRead1 = FileReadLine("C:\temp\sample.txt",1) For $count = 1 To _FileCountLines($FileRead1) Step 1 $string = FileReadLine($FileRead1, $count) $input = StringSplit($string, ",", 1) $value1 = $input[1] $value2 = $input[2] $value3 = $input[3] $value4 = $input[4] _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value1, "A1") _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value2, "B1") _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value3, "C1") _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value4, "D1") Next

      Hello,
      I'm trying to write a script that moves copies excel cells into an array. I'll than manipulate the values and send array into another program. 
      I don't want range to be specific to a workbook, or sheet, or set of cells.
      I want user to be able to highlight desired cells and to copy either normally ("Ctrl+C") or by a hotkey ("Alt+C"). 
      Could someone help me with this?
      Thank you,
      I've tried to write the framework: (edited)
      #include <MsgBoxConstants.au3> #include <Array.au3> #include <Excel.au3> HotKeySet("!v", "Pastedata") While True Sleep(1000) WEnd func Makearray() local $bArray ;User has cells already copied ;Convert clipboard into an array ;I don;t know how excel stores data to clipboard so don;t know how to bring it into array _Arraydisplay($bArray) MsgBox(0,0,$bArray) return $bArray endfunc func Pastedata() Local $aArray MsgBox(0,0,"wait",1) ;make array based on assumption user has already copied a range to clipboard $aArray = Makearray() ;paste code ;don;t worry about this I got the rest endfunc

      I want to make a while loop, that creates variables based on a array. For thist I created the array $iDsO with the number and the name of folders in an other folder. Every folder has a different name an I want to create variables(arrays) for each folder that show me all the files in that folder. For example: I have the Folder \Folder1. In it there are the Folders \1, \2, \3. In 1, 2 and 3 there are some files(.png). The array for Folder1 is $iDsO and now I want to crate the arrays $iDsO1, $iDsO2 and $iDsO3 with the files in them can I make something like this:
      While $iDs > 0 ;$iDs is the number of files in Folder1>> $iDsO[0] $iDs#here should come the Foldername for example '1'# = _FileListtoArray(@ProgramFilesDir&"\Folder1\"&$iDsO[$iDs]) $iDs = $iDs - 1 Wend So that in the End I have three variabels ($iDs1, $iDs2 and $iDs3)
       
      Is this posible or if not what could I do instead ( I don´t know the number of folders in Folder1 in the begining).
