I need to write a little VB 2005 WinForm app which, when a user drags-and-drops an attachment from an Outlook e-mail onto my app, my app saves that attachment to a specific folder. I just don't know how to implement drag-and-drop functionality as I've never done it before. I know one can drag an attachment from Outlook to Windows Explorer, for example, and it will copy the file to whichever folder it was dragged to. All the users are using Outlook 2007. Any help would be greatly appreciated.
