Attachment Type

[Neetu]

We are using VSTO 3.0 and Vb.net to create outlook addin for outlook 2007
We are extracting all attachments with a mail item.
iN some mail , signatures and background images are considered as attachments.

If there any way to find attachments of mail which are added as attachments
not signature image or back ground images?

Use the PropertyAccessor object for each attachment to see if the following
property is on the attachment:

PR_ATTACH_CONTENT_ID "urn:schemas:mailheader:content-id"

You can also check the string property PR_ATTACH_DISPOSITION
("http://schemas.microsoft.com/mapi/proptag/0x3716001E") and see if its
value is "inline".

hello Ken,

I googled a lot to get information on how to use these properties of
attachments however could not get any thing relevant.

If possible can i get some sample code for this.

Thanks
Neetu

If you have an attachment oAttach then the following code will access those
properties:

Outlook.PropertyAccessor prop = oAttach.PropertyAccessor;

string disposition =
(string)prop.GetProperty("http://schemas.microsoft.com/mapi/proptag/0x3716001E");

string contentID =
(string)prop.GetProperty("urn:schemas:mailheader:content-id");

if ((!String.IsNullOrEmpty(contentID)) ||
((!String.IsNullOrEmpty(disposition)) && (disposition.ToLower() ==
"inline")))
{
// is inline attachment
}

hey Ken
thanks for your reply but we are facing a problem with this piece of code
this line string disposition
=(string)prop.GetProperty("http://schemas.microsoft.com/mapi/proptag/0x3716001E");
is throwing an error saying
The property "http://schemas.microsoft.com/mapi/proptag/0x3716001E" is
unknown or cannot be found.

And
string contentID =
(string)prop.GetProperty("urn:schemas:mailheader:content-id");
this is throwing
The property "urn:schemas:mailheader:content-id" cannot be parsed or has an
invalid format.

can you please help me out

Those are named fields and may or may not be there. You have to be prepared
for that in your code, handling exceptions and testing for null or empty.
