Drag'n'drop one or more mails from Outlook to C# WPF application

I'm working on a windows client written in WPF with C# on .Net 3.5 Sp1, where a requirement is that data from emails received by clients can be stored in the database. Right now the easiest way to handle this is to copy and paste the text, subject, contact information and time received manually using an arthritis-inducing amount of ctrl-c/ctrl-v.

I thought that a simple way to handle this would be to allow the user to drag one or more emails from Outlook (they are all using Outlook 2007 currently) into the window, allowing my app to extract the necessary information and send it to the backend system for storage.

However, a few hours googling for information on this seem to indicate a shocking lack of information about this seemingly basic task. I would think that something like this would be useful in a lot of different settings, but all I've been able to find so far have been half-baked non-solutions.

Does anyone have any advice on how to do this? Since I am just going to read the mails and not send anything out or do anything evil, it would be nice with a solution that didn't involve the hated security pop ups, but anything beats not being able to do it at all.

Basically, if I could get a list of all the mail items that were selected, dragged and dropped from Outlook, I will be able to handle the rest myself!

Thanks!

I found a great article that should do exactly what you need to.

UPDATE

I was able to get the code in that article working in WPF with a little tweaking, below are the changes you need to make.

Change all references from System.Windows.Forms.IDataObject to System.Windows.IDataObject

In the OutlookDataObject constructor, change

FieldInfo innerDataField = this.underlyingDataObject.GetType().GetField("innerData", BindingFlags.NonPublic | BindingFlags.Instance);

To

FieldInfo innerDataField = this.underlyingDataObject.GetType().GetField("_innerData", BindingFlags.NonPublic | BindingFlags.Instance);

Change all DataFormats.GetFormat calls to DataFormats.GetDataFormat

Change the SetData implementation from

public void SetData(string format, bool autoConvert, object data)
{
    this.underlyingDataObject.SetData(format, autoConvert, data);
}

TO

public void SetData(string format, object data, bool autoConvert)
{
    this.underlyingDataObject.SetData(format, data, autoConvert);
}

With those changes, I was able to get it to save the messages to files as the article did. Sorry for the formatting, but numbered/bulleted lists don't work well with code snippets.
