How we can find out the format of the mail. "Vinayakc" <vinayakchitre[ at ]gmail.com> 1/13/2006 8:59:24 AM Hi all, I have written one Outlook add-in in C++. I want to detect the mail format of the mail through that add-in. ( RTF,HTML or Plain Text ). I have tried to do some search on this, I only got that, thorugh VBA we can use BodyFormat property of the mail item. How I can access this property through my C++ code? If Outlook is able to detect the format of incoming mail, I think we should also able to detect the format? Are there any MAPI properties which we can use for this? Through OutllookSpy when I look the properties of that mail item, I observerd that 1. HTML and RTF mails have PR_RTF_COMPRESSED property. 2. Plain text does not have PR_RTF_COMPRESSED property. 3. RTF mails have useTNEF property value as True and HTML mails have useTNEF property value as False. Will this observation help us?? Please reply as soon as possible. Thanks and Regards Vinayakc

Re: How we can find out the format of the mail. "Dmitry Streblechenko" <dmitry[ at ]dimastr.com> 1/15/2006 10:45:09 PM Read the RTFBody property and check if "\fromhtml1" is in the first 100 bytes or so: if yes, you have HTML. If you have "\fromtext" - it is text. Otherwise it is pure RTF. If RTF is missing, check if PR_HTML_BODY or PR_HTML is present.

Re: How we can find out the format of the mail. "Vinayakc" <vinayakchitre[ at ]gmail.com> 1/17/2006 10:28:14 AM Hi Dmitry, Thanks for your reply. I have searched for how to access the "RTFBody" property of the mail item. But I could not get anything on that. I want to use Outlook object model and MAPI propertries only. I am not using Redemption. Thanks and Regards Vinayakc.

"Dmitry Streblechenko" <dmitry[ at ]dimastr.com> 1/17/2006 5:59:31 PM Open the PR_RTF_COMPRESSED property from IMessage as IStream and uncompress it using WrapCompressedRtfStream function.
