Once you have created your PDF output via DominoPDF you may wish to attach the PDF file to a Notes document. Attaching a file can be carried out via LotusScript and an example is below.
Dim session As New NotesSession
Dim db As NotesDatabase
Dim rdoc As NotesDocument
Dim rt As NotesRichTextItem
Dim object As NotesEmbeddedObject
Set db = session.CurrentDatabase
Set rdoc = db.createdocument
rdoc.form = "Memo"
Set rt = New NotesRichTextItem (rdoc , "Body" )
Call rt.addnewline(2)
Call rt.appendtext("Here's your attachment --> ")
Set object = rt.EmbedObject( EMBED_ATTACHMENT, "", "c:\test.pdf")
Call rt.addnewline(2)
Call rdoc.save(True)
