Action for selected attachment only

Guest


Hi,

i need some actions only for an selected attachment in a mail item. It seems, it?s very dificult to do this.

I found here in the forum some hints about the Event in Outlook 2007 'AttachmentContextMenuDisplay'. But i can?t find any sample how i can do this.

In the MSDN, there are some sample snippets, but they don?t work in the environment with Addd-In-Express.

Can you help me?

I can?t understand, that?s so difficult to find the selected Attachment and work with it.

Regards

Thomas

Hi Thomas,

Intercept that event using the Outlook Events component. The event handler is invoked when you right-click an attachment (only in Outlook 2007-2010). In the event handler, you cast the target parameter to Outlook.AttachmentSelection (Outlook 2007 and higher); this object represents selected attachments. You access individual attachments using AttachmentSelection[i] or AttachmentSelection.Item(i); this call returns an Outlook.Attachment object (a COM object that must be released) representing an attachment. When the context menu is closed, Outlook generates the ContextMenuClose event.

Hi Andrei,

But i am ashamed, i don?t know, how i can cast the target Parameter.

Hi Thomas,

A raw sketch:

C# 
Outlook.AttachmentSelection attachmentsSelected = target as Outlook.AttachmentSelection;


VB.NET 
Dim attachmentsSelected as Outlook.AttachmentSelection  = CType(target, Outlook.AttachmentSelection)

Interops for what Outlook version you are using? Do you have the following Imports statement: 

Imports Outlook = Microsoft.Office.Interop.Outlook

Hi Thomas,

I suggest that you create a project for Outlook 2007 and test handling this event. Then, in case you really need to support earlier Outlook versions, you can use System.Type.InvokeMember to call required members of the AttachmentSelection interface in your real project.

If you prefer to go this route, you may want to read http://www.add-in-express.com/creating-addins-blog/2010/03/16/interop-assemblies-late-binding/
