Drag & Drop Outlook.MailIte m to a Windows.Forms.F orm and save it

Hi,

if I drag an Outlook.MailIte m to a Windows-Explorer window a
<subject>.msg file will be created.

Now I try to drag & drop a mail item to my own WinForm app.
Unfortunately it doesn't work. In the "drop event" are eight
DataFormats (e.Data.GetForm ats()) but the important one (imho)
"FileConten ts" is "Nothing"/"null".

Any ideas?

Hi Karsten,
I've been trying to get this to work my self, but so far haven't gotten any
further than to be able to drag and attachment in a mail to aWinForm.
The basic thinking behind a mail being dragged is a whole lot of COM and
interfaces. Here's the short version:

The objects (the mail(s)) being dropped is a COM class of IDataObject
interface.
It contains aFileGroupDescr ipter structure that contains an array of objects
(mails), so you can drag several mails at once.
Using the FORMATEDC and STGMEDIUM structures, it should be possible to get
the filename of the mail (eg. Message.msg), and a IStream interface to the
actual mail.
Once you have the IStream interface, it's easy to save it, but actually
getting there is much harder than what I had thought.

If you search MSDN, you'll find some samples on the various structures -
it's the same stuff MS uses for drag'n'drop and objects over the clipboard.
I have a C++ sample that does it all, as well as some VB.NET and C#.NET code
that allows you to drag an attachment from a mail. But not a .NET one that
saves the full mail.

Let me know if you want it - my email is (remove the spam)
sp****@spamlect or.spamdk
Perhaps we can get this shit to work together?

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
