What is the value of an empty array element?


Recommended Posts

I'm parsing an EditBox on an IM program stuffing arrays and sniffing array elements for particular strings. I've run into a problem, I do not know what an empty element is equal to. _ArrayDisplay shows nothing for $array nor does MsgBox show anything for $array[3].

I've tried IF $array[3] == ' ' Then

I've tried IF $array[3] == " " Then

I've tried IF $array[3] == 0 Then

Dim $a[2]

;$a[0] = 1

If $a[0] == '' Then
    MsgBox(0,"","EMPTY")
EndIf

that will not work

Sure it will work, that's why I posted the code!

This is what _ArrayDisplay() shows:

[0]= 2

[1] = element1

[2] = element2

[3] =

What is [3] = to?

Either empty (see my code) or not printable, try MsgBox(0,"",String($a[3])). Edited by /dev/null

Piano Man's trick worked

IF $array[3] == "" Then ... so an empty element is equal to "" ; no space between double quotes.

Thanks guys

So, what did I post? You did not even care to test it, right?
