[resolved] how to loop with an array to check if all cells have a value?

[kor 5]

sample code

I'm wondering how to check if every single cell in an array is not null.

#include <Array.au3>


Local $counter, $aSample[5] = ["one", "two", "three", "", "five"]

_ArrayDisplay($aSample)

For $i = 0 To UBound($aSample) - 1
If $aSample[$i] = "" Then $counter += 1
Next

If $counter = UBound($aSample) Then
ConsoleWrite("all cells have a value")
Else
ConsoleWrite("one or more cells do not have a value")
EndIf

What in your example code does not work?

You are counting the empty elements of the array.

So if none are emply, ($counter = 0), then "all cells have a value".

Should be:-

If $counter = 0 Then

Should be:-

If $counter = 0 Then

that works.

Thanks.

Am I even going about things the right way? Is there a better/easier way to see if all values in an array are not null?

Not that I know of. You have to loop through the whole array.

_ArrayFindAll seems to work

#include <Array.au3>
dim $Array[5]=["1","","",3,4]
$test = _ArrayFindAll ( $Array, "" )
ConsoleWrite ( UBound($test) & @CRLF )

Although this is looking for blank, not null
