[GD-Windows] Drag and drop from Outlook Express

[Pierre T. <p.t...@wa...>]

I'd like to be able to drag-and-drop mails from Outlook Express directly
into my app. I've already implemented drag-and-drop from files to a running
app in the past, it worked fine. But I'm not sure how to do that with mails
from Outlook.

When I drag a mail from Outlook to, say the Windows desktop, cursor changes
to the little "+" indicating drop is possible. Then a file is created, say
Mail.eml.

However, if I drag that same mail over my app (which otherwise supports
drag-and-drop of other files), the cursor doesn't change and nothing
happens.

So I guess there's something missing to enable that kind of interaction.
Ideally I'd like to get back the eml file(s) directly into my app, even if I
have to create them myself from whatever I get from Outlook when the drop
occurs...

Ideas ?

Cheers :)
