clearing Array

6 posts in this topic

is there fast and nice way to clear array? (clear all elements and probably free some memory....)

i can loop to delete element until end but i look for more elegant way :)

maybe delete and recreate array (if possible didnt find this option)

thanks!

hezi,

Just redeclare the array and it is emptied for you: :)

#include <Array.au3>

Global $aArray[3] = [1, 2, 3]

_ArrayDisplay($aArray)

Global $aArray[3]

_ArrayDisplay($aArray)

If you want to get rid of the array completely, just declare it as a simple variable - $aArray = 0. ;)

Another approach that will pass the Au3Check with advanced parameters >>

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

Global $aArray[3] = [1, 2, 3]
Global $aBackup[UBound($aArray)] ; Create a blank array.

_ArrayDisplay($aArray)

$aArray = $aBackup

_ArrayDisplay($aArray)

Or another way is this >>

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

Global $a1D[5] = [1, 2, 3, 4, 5]

_ArrayDisplay($a1D)

_ArrayClear($a1D)

_ArrayDisplay($a1D)

Func _ArrayClear(ByRef $aArray)
    Local $iCols = UBound($aArray, 2)
    Local $iDim = UBound($aArray, 0)
    Local $iRows = UBound($aArray, 1)
    If $iDim = 1 Then
        Local $aArray1D[$iRows]
        $aArray = $aArray1D
    Else
        Local $aArray2D[$iRows][$iCols]
        $aArray = $aArray2D

      Hi all, 

      First, I want to give a huge shout-out to the community. I'm completely self-taught, and have never had to actually ask a question before because the forum is that good at answering questions and explaining things. However, I'm kind of stumped here, and I've been stuck on this problem for almost a full day.

      I'm working on a script to populate drafts of deeds at work. I have the main GUI and  a function (ctrl($n) and read()) for adding fields to find and data to replace it with to an array for later use with _word_docfindreplace. All of that works. However, due to the way I have the forms set up, I need to create additional fields and info based on the data that's there. Specifically, if there's only one buyer, I need to add the field [Buyer1&2] and the data in $aArray_Base for [Buyer 1]. I also need to add a field [Buyer 2] and have a blank data set in the next column over in the array, and I need to do the same for the Seller. To this end, the function parties() sets boolean variables $2buyers and $2sellers accordingly. Then, I have buyers() and sellers() to populate the data. 

      The problem that I'm running into is that each function works... when ONLY the buyer 1 name field is filled, and when ONLY the seller 1 field is filled.

      So if I fill Buyer 1 Name and save it, the data is populated correctly. But when I fill Buyer 1 and Seller 1 name, only the buyer 1 data populates correctly. Worse, when I fill several fields, neither populate correctly. I have no idea why this happens. I've added messageboxes to debug throughout the entire process and can't pinpoint what's causing the issue. The entire script is below. The function(s) in question are buyers() and sellers(). Only Sellers() has messageboxes throughout.

      Can someone help walk me through what might be causing this and help me find a solution? Thanks a ton in advance, and sorry for the wall of text.

      Hi everybody,
      i have a question related to strings items in an Array and sorting. Maybe someone can advice me how to solve the issue.
      I have an Array of strings, every item of the Array is as following:
      INFO [13.06.2017 11:48:01] [Thread-13] [ConGenImpUsb -> waitForConnection]  INFO [07.06.2017 08:55:44] [main] MDU5 - Ver 5.1x I want to sort the item in the array by date and time, is there any function which allows me to sort by date/time?
      Thanks in advance
