Retrieving string from DllStruct

[monoceres]

A sample says more than a thousand words:

$s=DllStructCreate("char[255]")

$str=""
For $i=0 To 253
    $str&=Chr(Random(1,255,1))
Next
; Set the string to some random data
DllStructSetData($s,1,$str)

; Retrieve the string the usual way
$fromstruct=DllStructGetData($s,1)

; Get the string, char by char
$fromstruct2=""
For $i=1 To 254
    $fromstruct2&=DllStructGetData($s,1,$i)
Next

; They're not equal :/
MsgBox(0,($fromstruct==$fromstruct2),$fromstruct&@CRLF&@CRLF&$fromstruct2)

I just cannot see the difference, I thought the only difference would be that AutoIt would stop reading at Chr(0) in the first method.

char is for ASCII char and you are filling it with over 127.

use wchar to get the same results if you are going over 127

Aaaw, I forgot that char is unsigned

I once forgot how old I am. This girl, lady actually, asked me and I just couldnt't remember. Nooo way. It was so embarrassing. While she waited there for my answer I tried to calculate it from my birth year (somehow did remember that) but just couldn't. Mainly because I couldn't remember what year it was.

So this is nothing. Don't worry.

edit:

btw, don't tell anyone this. I don't want it spread. It's a secret.
