The article here sounds specific to Outlook 2007 and VBA/Visual Basic, but is equally applicable to any Windows Application that wants to automate Outlook:

Keep in mind the Caution disclaimer at the bottom over this "non-trusted" approach.

Once you're "in", you get get a handle to the active item via Application.ActiveInspector.CurrentItem. Then use MailItem.Attachments.Add.

You also need to keep this in mind:
