How to get array elements from reference ?

manishrathi has asked for the wisdom of the Perl Monks concerning the following question:

I have following code.

$wfs = $system->GetActiveWorkflows();

$wfs is a reference to an array containing references to TeamSite::WFworkflow objects.

Now, I want to get all the elements (each workflow) from this array. How can I get it ? It looks that this $wfs will give the number of elements. Do I need to use @wfs = $system->GetActiveWorkflows() ?

Thanks

$wfs is a reference to an array I doubt that. What does the TeamSite documentation say? Most likely, `->GetActiveWorkflows()` returns an OLE collection, which would mean you have to work with `$wfs->Count` and `$wfs->Item()` or the `in` function of Win32::OLE. If `$wfs` really contains a number after your assignment, then what you proposed should work. What happened when you tried it?	[reply] [d/l] [select]

What you got back is a reference to an array. See References Quick Reference and maybe perldsc.	[reply]
