Array range and ArrayDelete

[LoneWolf_2106]

Hi,

i would like to specify the array range to delete some items in my array. I don't know why the resulting array is the same.

Here is my code:

 

While $last_index >= $first_index

    _ArrayDelete($aFile_Array_Original, $aFile_Array_Original[$last_index])
    $last_index-=1

WEnd

 Is there any way to pass directly the range to ArrayDelete, avoiding the loop?

Thanks in advance.

Read the help file for _ArrayDelete and look at the remarks section. All will become clear to you.

You mean that i should specify a range in the following way?

$range_deletion=$first_index&";"&$last_index

If it is so, it didn't work.

so can we see the array (or an example), and what you are setting for $first_index and $last_index prior to entering the loop.  If it is indeed the actual last element you are removing you might consider _ArrayPop and just discarding the return.

@iamtheky the Indexes are correct, but arraydelete doesn't delete all the items between the two indexes.

Everything between  $first_index and $last_index must be deleted.

 

Fyi, all the lines before _ArrayDelete are working correctly

 

_ArrayDisplay($aDate_CSV, "My date")

Local $Day=$aDate_CSV[1]
Local $Month=$aDate_CSV[2]
Local $Year=$aDate_CSV[3]

$Day_To_Delete= $Day+1

$sString_To_Delete="INFO ["&$Day_To_Delete&"."&$Month&"."&$Year

$Entry_to_Delete_Indexes_2=_ArrayFindAll($aFile_Array_Original, $sString_To_Delete, 0, 0, 0, 1)
.
.
.
$first_index=$Entry_to_Delete_Indexes_2[0]

$last_index=UBound($aFile_Array_Original) -1

 

My array is a list of entries like the following one:

 

INFO [15.09.2017 19:08:31].......

INFO [15.09.2017 19:08:32].......

INFO [15.09.2017 19:08:33].......

[iamtheky]

the semicolon in your code in post #3 says "this element AND this other element"  you need to use a dash if you want "this element through this other element".

I commented the helpfile example in case its easier to see that way:

#include <Array.au3>

Local $aArray_Base[25][4]
For $i = 0 To 24
    For $j = 0 To 3
        $aArray_Base[$i][$j] = $i & "-" & $j
    Next
Next

; Range string
$aArray = $aArray_Base
Local $sRange = "0;11-15;24"  ;This String removes element 0, elements 11 thru 15, And element 24
_ArrayDisplay($aArray, "BEFORE deletion")
_ArrayDelete($aArray, $sRange)
ConsoleWrite(" " & @error & @CRLF)
_ArrayDisplay($aArray, "RANGE STRING deleted")

By the way, you're only avoiding the loop in your own code, _ArrayDelete uses a loop to delete the range.

@iamtheky, thanks, it is working, i am testing it

@BrewManNH, thanks for the info, next time i will use just _ArrayDelete without any loop
