Trying to hide inline attachments


K

krach.aran

I am writing some code to archive mail.
whel looping through my selection i check every e-mail to see if it
contains any attachments. However the outlook api gives me a number of
inline attachments that i don't want to see. I only want to see the
attachments that are visible via the paperclip icon in office.

Does anybody now of a way of detecting these inline attachments.

I tried to look at the attachment.type property, but this is not the
way to go.
I tried analysing the htmlbody to look for the filename, but this was
also no help.

TIA

Otto

And the cid will be the same as in the PR_ATTACH_CONTENT_ID (0x3712001E or
urn:schemas:mailheader:content-id) property on the attachment object. That
will give you what to look for if you you're using Outlook 2007 or Extended
MAPI or CDO 1.21 or some other API that allows access to properties not
exposed in the Outlook 2003 or earlier object models.

This worked for me (don't mid the sloppy code.... cleaners are on
their way ;) ):

public static bool IsValidAttachment(Outlook.MailItem
mailitem, Outlook.Attachment attachment)
{
bool retval = false;
string CID = "";

try
{
if (attachment.FileName != "")
{
// this skips the olOLE types

MAPI.Session session = new Session();
session.Logon("", "", false, false, Type.Missing,
Type.Missing, Type.Missing);
MAPI.Message message =
(MAPI.Message)session.GetMessage(mailitem.EntryID, "");
MAPI.Attachments atts =
(Attachments)message.Attachments;


for (int teller = 0; teller <
mailitem.Attachments.Count; teller++)
{
MAPI.Attachment att =
(MAPI.Attachment)atts.get_Item(teller+1);


MAPI.Fields fields = (MAPI.Fields)att.Fields;
MAPI.Field field =
(MAPI.Field)fields.get_Item(MAPI.CdoPropTags.CdoPR_ATTACH_FILENAME,
null);

if ((string)field.Value ==
attachment.FileName)
{
field =
(MAPI.Field)fields.get_Item(0x3712001F, null);
CID = (string)field.Value;

field =
(MAPI.Field)fields.get_Item(0x37140003, null);


if (!CID.StartsWith(attachment.FileName)
&& (int)field.Value !=4)
retval = true;
}
}
session.Logoff();
}
}
catch
{

}

if (attachment.Type ==
Microsoft.Office.Interop.Outlook.OlAttachmentType.olByValue && CID ==
"")
retval = true;

return retval;
}

Exactly what I was looking for and so obscure! Thanks so much for posting this.

The problem with detecting inline attachments seems only to occur when using HTML mail. The RTF setting doesn't seem to create them.
