PerryRaptor 1 Posted February 6, 2007 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].

/dev/null 2 Posted February 6, 2007 (edited) 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])).
