String BUG (or as it happens NOT)

Recommended Posts

Grayhat

As you may know, strings must be NULL terminated ('0').

Not in AU3, as

$String1 = BinaryToString("0x74657374")
$String2 = BinaryToString("0x746573740000")
MsgBox(64, "Equals", $String1 == $String2)

returns False.

Because it's not the same text in the 2 strings, that's why it returns as false.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

If you see a string like this:

[T][e][t][0]

[T][e][t][0][0][0]

they are the same.

No, they're not, not in AutoIt, welcome to the reality that not everything works the way you're used to in other languages.

I don't see anywhere where it says strings must be NULL terminated.

You are making an assumption about an implementation detail.

Keep in mind the difference between C strings and higher level strings. String objects contain a length property which indicates how long it is, not the null character. This is standard in higher level languages where strings may contain embedded nulls.
