Alex, I'll swap you Mac for Windows. To do this on the Mac, your stack needs to handle the "appleEvent" message. Put the following handler in your stack script: on appleEvent eClass, eID, eSender if eClass = "odoc" then request appleEvent data if the result = empty then answer "OpenDoc AppleEvent!" & return \ & "id =" && eID \ & "sender =" && eSender \ & "data =" && it else pass appleEvent end if else pass appleEvent end if end appleEvent Build a standalone, and try it. You should see that when you drag and drop a file, this handler fires, and the data for the apple event is the path of the file(s). The issue about which files you can drag-and-drop onto your app is determined by the resources in the app. When the standalone is built, it is given the same resources as MetaCard itself - so it accepts stacks. You need to change these resources to identify the kind of files your app should accept. The resources in question are the file reference ('FREF'), icon list ('ICN#') and bundle ('BNDL') resources. You should be able to get information about these on the apple site (developer.apple.com) (I'm on the road at the moment, with email access only - can't give you exact referencess.) You'll need a resource editor - ResEdit or Resorceror. Note that you can only filter by Mac type codes, not by file extensions. Now: can you tell me how I do this on Windows?!? I can't even find out how to access the environment variables.
