The Domino server API getEmbeddedObjects();
returns the wrong result (z开发者_运维技巧ero) when a mail containing an attachment (as embedded object) is sent from the script.
Though an attachment is sent as an EmbeddedOBject
, getEmbeddedObjects();
returns ZERO
.
The mail type is NOT MIME
.
This is a Java application. Is there is any workaround for this problem?
I take the body from the document. If the body is of richtextitem, I call the getEmbeddedObjects() which returns zero though an attachment is present as embedded object.
Looking through all of the items in a document for the possibility of an attachment is doing a lot of work for nothing. All you need to do is get the collection of attachment names using the @AttachmentNames formula (available through the evaluate() method of the Session object, using the Document argument), and if the collection contains more than an empty string, use the getAttachment() method of the document to get a handle to the corresponding EmbeddedObject.
getAttachment() can grab any attachment to a document, whether it's associated with a RichTextItem or a V2-style attachment (as would be created by a web UI or when converting external mail). And never be afraid to use Formula Language when it's appropriate -- it can make your life a whole lot simpler.
Attachments do not necessarily have to be embedded inside a RichText field. To quote from the designer-help:
If you need access to OLE/2 embedded objects that exist in a document but are not part of a rich text item (for example, because the object was originally created on the document's form), use the EmbeddedObjects property in Document.
Another source of your problem could be, that there are several "Body" RichText items you would have to check.
HTH
Lotus Notes does not provide a single reliable method for extracting attachments from a NotesDocument object, unfortunately. To be thorough, you'll need to check through all richtext items it contains, as well as the document object itself.
I wrote the following code to extract attachments from selected emails in a mailbox, in an effort to cut down the file size (my users saved everything). The main loop is relevant to your question, though. It shows the process of looping through all of the document's items looking for richtext items with attachments, followed by a loop through all items again looking for items of type "Attachment".
(forgive the hackiness of the code. It wasn't written for efficiency)
Sub Initialize
Set s = New NotesSession
Set db = s.CurrentDatabase
Set dc = db.UnprocessedDocuments
Set doc = dc.GetFirstDocument
Dim rtItem As NotesRichTextItem
Dim RichTextItemNames List As String
Dim DocumentItemNames List As String
Dim itemCount as Integer
While Not (doc Is Nothing)
'Scan all richtext items in document for embedded objects
Forall i In doc.Items
If i.Type = RICHTEXT Then
Set rtItem = doc.GetFirstItem(i.Name)
If Not Isempty(rtItem.EmbeddedObjects) Then
RichTextItemNames(itemCount) = Cstr(i.Name)
itemCount = itemCount + 1
End If
End If
End Forall
'Loop through richtext items and extract the embedded attachments
For j = 0 To itemCount - 1
Set rtItem = doc.GetfirstItem(RichTextItemNames(j))
Forall Obj In rtItem.EmbeddedObjects
If ( Obj.Type = EMBED_ATTACHMENT ) Then
Call ExportAttachment(Obj)
Call Obj.Remove
Call doc.Save( False, True ) 'creates conflict doc if conflict exists
End If
End Forall
Next
'Scan all items in document for Attachment type items
itemCount = 0
Forall i In doc.Items
If i.Type = ATTACHMENT Then
DocumentItemNames(itemCount) = i.Values(0)
itemCount = itemCount + 1
End If
End Forall
'Loop through all attachment items in document and extract them
For j = 0 To itemCount - 1
Set attachmentObject = doc.GetAttachment(DocumentItemNames(j))
Call ExportAttachment(attachmentObject)
Call attachmentObject.Remove
Call doc.Save( False, True ) 'creates conflict doc if conflict exists
Next
Set doc = dc.GetNextDocument(doc)
Wend
End Sub
Sub ExportAttachment(o As Variant)
Dim sAttachmentName As String
Dim sNum As String
Dim sTemp As String
' Append number to end of filename if filename exists.
sAttachmentName = sDir & "\" & o.Source
While Not (Dir$(sAttachmentName, 0) = "")
sNum = Right(Strleftback(sAttachmentName, "."), 2)
If Isnumeric(sNum) Then
sTemp = Strleftback(sAttachmentName, ".")
sTemp = Left(sTemp, Len(sTemp) - 2)
sAttachmentName = sTemp & Format$(Cint(sNum) + 1, "##00") & _
"." & Strrightback(sAttachmentName, ".")
Else
sAttachmentName = Strleftback(sAttachmentName, ".") & _
"01." & Strrightback(sAttachmentName, ".")
End If
Wend
Print "Exporting " & sAttachmentName
'Save the file
Call o.ExtractFile( sAttachmentName )
End Sub
If you get the embedded objects from the Document
object, they won't contain attachments. Using getEmbeddedObjects
with the "Body" RichTextItem
gets the attachments too.
Does that help?
