Stringleft and Array

[ahmeddzcom]

Hello

Can Stringleft a array ?

#include <array.au3>

Local $aArray = [1111, 2222222222, 333333333333333333333]

_ArrayDisplay($aArray)

$SLeft = StringLeft($aArray,3)

_ArrayDisplay($SLeft)  ;~  this not work of course :)

so the result is ; 111 , 222 , 333

tnx.

Take a look at the _ArrayTrim function.

[Musashi]

Or :

#include <array.au3>
Local $aArray = [111111111, 2222222222, 3333333333]
_ArrayDisplay($aArray)

For $i = 0 To UBound ($aArray) -1 Step 1
    $aArray[$i] = StringLeft($aArray[$i] , 3)
Next
_ArrayDisplay($aArray)

Hi @ahmeddzcom,

like @Musashi already posted (only few minutes before I could write this here down 😅😞

#include-once
#include <Array.au3>

Local $aArray = [1111111111, 2222222222, 3333333333]
_ArrayDisplay($aArray, 'Before')

Local Const $aNewArray = _StringLeftIn1dArray($aArray, 3)
_ArrayDisplay($aNewArray, 'After')

Func _StringLeftIn1dArray($aArray, $iCount)
    For $i = 0 To Ubound($aArray) - 1 Step 1
        $aArray[$i] = StringLeft($aArray[$i], $iCount)
    Next

    Return $aArray
EndFunc

[...] anyways, I guess the suggestion of @Danp2 might be the best - it's already provided by AutoIt, so no need for a custom function.

Best regards
Sven

I am a bit confused @ahmeddzcom, because the solution should be @Danp2s post in my opinion. Of course at the end it's up to you what you prefer (and also sorry to @Musashi - nothing personaly 😇). But for other people it would be more helpful to know about what is already provided by AutoIt (Danp2 post) and this should be the solution.

Best regards

i can't use _ArrayTrim . Because _ArrayTrim  remove only (remove left and rigth) . i need get three characters 
 so i think  _ArrayTrim not working for me 😃

See: _ArrayTrim online doc

The option is to remove left OR right.

Hi @OJBakker

i think  _ArrayTrim not working with this code :

#include <array.au3>
Local $aArray = [1111, 2222222222, 333333333333333333333333]
_ArrayDisplay($aArray)

For $i = 0 To UBound ($aArray) -1 Step 1
    $aArray[$i] = StringLeft($aArray[$i] , 3)
Next
_ArrayDisplay($aArray)

You are right. _ArrayTrim() won't work.

You want as parameter: Number of characters to remove.

_ArrayTrim() wants as parameter: Number of characters to trim.

[Musashi]

@ahmeddzcom :

You will now encounter another problem:
In your original question, the elements of the array looked like this :

Local $aArray = [111111111, 2222222222, 3333333333]

An hour ago you edited your starting post, and now it contains the following values :

Local $aArray = [1111, 2222222222, 333333333333333333333333]

The integer value 333333333333333333333333 is outside the allowed limits, i.e. :

-2^63 largest negative value , 2^63-1 largest positive value (= 9223372036854775807)  .

As a result, the element $sArray is displayed as 9223372036854775807 not as 333333333333333333333333

@Musashi

yes i did , because i need trim lines not have the same number of characters

I got that . The problem is the size of the third value.

If you need to work with values that exceed the above limits, then it is worth taking a look at the bignum-udf

Here are two one-liners that will return StringLeft() and StringRight() of all items in a 1D or 2D array.

#include <array.au3>

; 1D Aarray
Local $aArray[] = ["02", 1234, 23456789, "3456733333333333333333333"]

; Or, 2D Array
;Local $aArray[][] = [["02", 1234, 23456789, "3456733333333333333333333"],["ab", "cdefg","hijklmnop"]]

_ArrayDisplay($aArray)

$aArray1 = _ArrayFromString(StringRegExpReplace(_ArrayToString($aArray, "!"), "([^!\v]{3}).[^!\v]*", "\1"),  "!") ; _ArrayAllItemsStringLeft
_ArrayDisplay($aArray1, "Left")

$aArray2 = _ArrayFromString(StringRegExpReplace(_ArrayToString($aArray,  "!"), "[^!\v]*([^!\v]{3})", "\1"),  "!") ; _ArrayAllItemsStringRight
_ArrayDisplay($aArray2, "Right")

 thanx @Malkey
exactly what I needed 😃
