Creating an Array with Nothing

3 posts in this topic

I'm writeing a function that adds to an Array a list of words. At the end of the function, the Array CAN be empty, and what I would like is for that to happen, so that I can just test how many variables are in the Array, and if there are 0, then there is was an error. So what I wanted to do was create an "Array" at the top of the function, and go through the checks that do or do not add words to the list. Problem is, there is no way to create an $Array[0], and _ArrayAdd( $, $) wont add to a non Array, $Array. I tried doing a Dim $Array; because I looked in Array.au3 and saw that it ReDim's the variable, but apparently ReDiming only works on a previous array. Is the only way arround this be to create my own Link List type deal? or.. ? Another question I have is handleing variable's with shallow and deep copy, I have run into a few times where I have found that AutoIt likes its Shallow Copy. (My termonology may be wrong) what I am refering to is how can I take the physical memory location of $bob and make $bob2 = $bob; In functions, I have applied Globally declared variables $Letters = $ArrayCreatedInFunction; and the $Letters functions as that array during the scope of the function.

Hi,

why do you want to check for 0. You can check everything else.

#include<Array.au3>
Dim $array[1] = ['check']
If IsArray($array) Then
    _ArrayAdd($array, '1')
    _ArrayAdd($array, '2')
    _ArrayAdd($array, '3')
    _ArrayAdd($array, '4')
    _ArrayDisplay($array, "Array")
Else
    ConsoleWrite("Damn")
EndIf

If $array[0] <> "check" Or UBound($array) = 1 Then
    MsgBox(0, "error", "error nothing added")
Else
    MsgBox(0, "Added", UBound($array)-1)
EndIf

So long,

Mega
