#183312 - 2007-12-05 09:02 PM Collection or Dictionary Object
phatfish phatfish Wasted Registered: 2007-12-05 Posts: 6 Loc: England	Hi, I would like to create a Collection or Dictionary Object, the same as used in VB6; and populate it with some data. Is it possible to create either in a Kixtart script? Thanks

This object is an associative array, sometimes called a hashed or named pair. You can think of it as a very simple database table comprising a single key and a single data field. This type of array uses an arbitrary key that you define as the index instead of a numeric index, so for example you could do: Code: $asRipeFruitArray["Banana"]="Yellow" "A ripe banana is "+$asRipeFruitArray["Banana"]+@CRLF Associative arrays come up for discussion quite regularly.

phatfish phatfish Wasted Registered: 2007-12-05 Posts: 6 Loc: England	Yes Richard, thats what i was looking for. As far as i can tell Kixtart doesn't support associative arrays. However there is an issue with handling the Dictionary object in Kixtart as described here http://www.kixtart.org/forums/ubbthreads.php?ubb=showflat&Board=8&Number=154637 that has meant i cant achieve exactly what i want. There is a workaround described in that post that i might end up using, but its not ideal.

Depending on the requirements of your project they can work very well if a bit slower. You can also use wrapper UDFs to provide associative array functionality on top of plain old arrays. I'm pretty sure I did just that a while back - I'll dig the code out if I get a chance.

Howard Bullock Howard Bullock KiX Supporter Registered: 2000-09-15 Posts: 5809 Loc: Harrisburg, PA USA	I have already posted a number of UDFs that emulate Perl HASHes. These may be a useful alternative. This code uses KiX arrays. It is slower then using the COM dictionary object. There are also examples of using the COM dictionary objects. I think I even posted their use as part of a Golf outing. Edited by Howard Bullock (2007-12-06 05:35 PM) Edit Reason: spelling _________________________ Home page: http://www.kixhelp.com/hb/
