drag and drop Outlook attachment from Outlook in to a WPF datagrid

I saw this code ealier about drag and dropping attachment files (http://www.codeproject.com/Articles/28209/Outlook-Drag-and-Drop-in-C) from Outlook into Windows Form and it works fine in windows Forms, but I can't seem to make it work with WPF. I tried to simply change System.windows.form.IDataObject to System.Windows.IDataObject but it doesn't work (as I should have guessed).

I also simply tried to get the content of the e.Data FileContents but always get errors (which seems to be the case to everyone when I check on the web).

Did anyone ever did drag and dropping attachment from Outlook to WPF ? I am at a complete loss.

Edit : I am not trying to get file from a Windows Explorer windows ( I do but I know how to). It's really the whole getting attachment from Outlook directly that doesn't work . I am fully aware too that I could simple take the file from outlook into a temp folder and then drop it into my program, but I would like to avoid this unncessary step if possible.

so in the end I was able to find out a link where someone did exactly that :

https://gist.github.com/MattyBoy4444/521547

For those who wonders. Here is what I did exactly.

  • Create a new project in C# (my code is in VB) and add the code to it
  • Reference the new project in my main project to be able to use it
  • In my drop Event, check whether or not I had the "FileGroupDescriptorW" object in the drop data and called the method if I do to retrieve the files.

Here is the complete code

If obj.GetDataPresent("FileGroupDescriptorW") Then 'Outlook
    Dim oOutLookObj As New Helpers.OutlookDataObject(e.Data)
    Dim StrFiles() As String = oOutLookObj.GetData("FileGroupDescriptorW")
    Dim contentStream() As System.IO.MemoryStream = oOutLookObj.GetData("FileContents")
    ' Do intended work...
End if

The names of the files are in StrFiles and the content are found in the streams. Both have the same array size and are order correctly.
