MAC ONLY. Generates applescript to choose file & returns result

Sample Input:
Perform Applescript ( AS_ChooseFile ( "TO::FieldName" ; "Choose a file please..." ; "/Macintosh HD/Users/Shared/" ; "csv¶jpeg¶jpg" )
Sample Output:
Brings up choose file dialog at default location specified (limits selection to list if specified)

Returns full file path for file:
"Macintosh HD:Users:Shared:tmp:fileOfMyChoice.csv"

Result is returned either to global field specified or to clipboard so a simple paste will do the job.

 Then copy & paste into FileMaker Advanced's Edit Custom Function window.


cousin to AS_Choosefolder

Uses Applescripts' Choose File dialog

Allows you to filter by filetype. I've not bothered implement choosing multiples/invisibles.

This is my Custom Function and I want to edit it


I've just been using this myself, and for some reason it's not working, so had to change _defaultLocation line thus:

_defaultLocation = Case ( IsEmpty(_defaultLocation) ; "" ; Position ( _defaultLocation ; ":" ; 0 ; 1) or Position ( _defaultLocation ; "/" ; 0 ; 1); "\"" & Substitute ( ":" & _defaultLocation & ":" ; ["::"; ":"] ; [":" ; "/"] ; ["//"; "/"]) & "\"" );

bit of a pain, thought i'd thoroughly tested it, but maybe i changed system since i last used it...
