You need to pass a CFArrayRef to the directories parameter. See the
Core Foundation chapter of my declares book at <http://
www.declareSub.com/> for some explanation.

I'm trying to build a declare, but it's not a function, it's a
method, i.e. there's not supposed to be any return value and I
can't find the RB syntax for it. Also it says I can't pass arrays...
What I have so far is below and gives me a hard crash:
Sub TextChange()
Dim i As Integer
Declare function MDQuerySetSearchScope Lib "Carbon" (QueryRef as
integer, Directories as CFStringRef, Optionbits as integer) as integer
If not Query.Completed then Query.Stop
Query.Query ="kMDItemDisplayName = ""*"+me.Text+"*""wc"
i = MDQuerySetSearchScope(Query.Handle,"",0)
Query.Run
'void MDQuerySetSearchScope (
'MDQueryRef query,
'CFArrayRef scopeDirectories,
'OptionBits scopeOptions
');
End Sub
'Directories' should be an array. Does anybody have an example on
how to build a CFStringRef that represents a directory?
Any pointers would be appreciated.
Thanks,

Hi Jon,
Can you give me some sample code to get me started? I've never
done the 'declare thing' before.
Thanks,
Marc
I would like to limit the search scope of Spotlight to a
particular folder (and its sub-folders).
The current RB implementation doesn't allow this. Can anybody
provide an example on how declares could be used?
You should be able to set up the SpotlightQuery, then declare
against MDQuerySetSearchScope passing in the
SpotlightQuery.Handle. Because of how the MDQuery API is, any
change to the query string will cause REALbasic to recreate the
MDQueryRef underneath the hood, which will require you to re-set
the scope afterwards.
