Having shown how to hit iTunes from VW, here's how I did the same thing in ObjectStudio. OST is more Windows oriented, so things were a bit simpler:
"Get a COM interface and a dispatch object" ole := OLEObject newProgId: 'iTunes.Application'. dispatcher := ole dispatcher. "get the Playlist interface" libPlay := dispatcher at: 'LibraryPlaylist'. "Now add the file" result := libPlay call: 'AddFile' params: (Array with: 'h:\audio\industry_misinterpretations_10-14-06.mp3').
Refer back to the same image from the previous post; it all worked the same way :) COM from Smalltalk isn't quite as hard as I thought it was.
