DragDrop attachments from outlook (2010) on a listview (or any other component)

I'm trying to understand if it's possible to support OleDragDrop attachments directly from outlook to our application.

The format's that are given aren't documented in any VB6 document.
There are 3 supported formats when I check the Data object during the OleDragOver event:

• -16110: Seems like ANSI version of the filename (at least that what I can understand from dumping the GetData(-16110) to a bytearray)
• -16109: Seems like Unicode version of the filename (at least that what I can understand from dumping the GetData(-16109) to a bytearray)
• -15691: ????? Don't know, as GetData(-15691) gives me the error "Specified format doesn't match format of data" or "Method 'GetData' of object 'IVBDataObject' failed" (depends if I first use GetFormat(-15691)).

Any idea if it's possible to get the actual data somehow?
