I have a Win Form application that does some boring accounting stuff and then sends it’s data to some lucky recipients. I am using the Outlook 12.0 Interop objects and my applications environment ranges from office 2003 on XP to office 2007 on Win 7.
My issue lies with sending the corporate signature with the sent emails.
It contains two images and I would like to embed these images so they appear to be part of the body (assuming the receiving mail client supports that).
I have tried a few different methods of accomplishing this; but still no luck!
I have tried:
-
Extracting the html data from the signatures folder, changing the
html img tags src attribute to include ‘file///’. This causes Outlook
to replace the ‘file///’ with ‘CID’ and I assumed it would also embed
the image… we should never assume :|. This is the method I found
worked best for getting the rest of the signature. -
(After creating a new MailItem) – Grabbing the HTMLBody of the MailItem
and extracting the relevant part including the signature… This
didnt work due to the new MailItem object being very inconsistent
with it’s signature. By that I mean sometimes the new item would
include the signature and sometimes it wouldn’t! :s I cannot figure out why it is not always there, no other part of my code has changed!
I read on another post here about the GetInspector property… Apparently just calling this will do ‘Some stuff’ and the signature will magically appear in your mail item… NO!
Things I can’t do:
- I cannot (as much as i would like to) shove the images online
somewhere and point to them in the emails html. - I cannot use SMTP(It has to be through Outlook… sigh).
I am thinking that the best way seems to be my original method of messing about with the CID, but I do not really know much about what Outlook is doing in the background so I am having trouble figuring out what else I need to do to get the images sent along with the email.
Hoping someone out there has some idea about what I am doing wrong or what else I could try.
Please let me know if code would be helpful and I will post, (Most of the code tried is from this site… I just cannot find the links again and am trying to avoid making this question tooooo long).
Many thanks
This is not the most efficient or flexible solution you can use, but probably the most robust and portable. You can convert your image bitmap into plain HTML and embed that HTML in your e-mail signature.
The conversion is quite simple, you can use the utility I wrote (open source) here.
