Adding a header item with MAPI Tom at GSD 1/5/2007 11:58:02 PM Hi, I have developed an ATL/C++ add-in that I want to add a header item to a _MailItem before I forward the email. The idea is that I take an item out of the inbox, modify the header and then forward it to another email address. I see there are Redemption examples; but I do not want to use the redemption libraries. Is there an extended MAPI example that will show me how to accomplish this? I do not want to use any third party utilities. I have looked for examples on the web but I do not see any. Thanks, Tom -

Re: Adding a header item with MAPI "Dmitry Streblechenko" <dmitry[ at ]dimastr.com> 1/6/2007 7:18:29 AM 1. Read MailItem.MAPIOBJECT property 2. QI it for IMessage Extended MAPI interface 3. Call IMessage::GetIDsFromNames() passing the appropriate GUID and id 4. "Or" the retirned tag with the appropriate type (PT_STRING8) 5. Use Imessage::SetProps or HrSetOneProp to set the property with tag from #4.

Re: Adding a header item with MAPI Tom at GSD 1/6/2007 4:08:00 PM Thanks Dmitry - I will give that a try. I was using the following code snippit but it seemed not to be working properly IUnknownPtr pUnk = spForward->GetMAPIOBJECT(); CComQIPtr<IMAPIProp, &IID_IMAPIProp> pMAPIProp(pUnk); ATLASSERT(pMAPIProp); SPropTagArray ar = {0}; ULONG nProps = 0; SPropValue *arProps = NULL; TCHAR*szResult = NULL; ar.cValues = 1; ar.aulPropTag[0] = PR_TRANSPORT_MESSAGE_HEADERS; pMAPIProp->GetProps(&ar, PT_UNSPECIFIED, &nProps, &arProps); "Dmitry Streblechenko" wrote: [Quoted Text] > 1.

Re: Adding a header item with MAPI Tom at GSD 1/6/2007 5:01:00 PM Now it makes sense. :-) I have been looking for a book or some reference material on MAPI programming and I have yet to find one. I have a book written by Dave Grundgeiger; but it is very high level, uses VB and really is a CDO reference. Do you have any book recommendations? Thanks!

Re: Adding a header item with MAPI "Dmitry Streblechenko" <dmitry[ at ]dimastr.com> 1/6/2007 5:48:15 PM "Inside MAPI" is the omly MAPI book ever published - it's been out of print for ages, but you can get it in the PDF format from http://www.insidemapi.com It won't cover this particular question of course :-) Otherwise just post your questions to the microsoft.public.win32.programmer.messaging newsgroup or use the MAPI list (http://peach.ease.lsoft.com/Archives/mapi-l.html).

Re: Adding a header item with MAPI Tom at GSD 1/8/2007 6:14:01 PM Hi Again Dmitry, I ran into a slight issue that I seem not to be able to fix. I am adding the header information to my out going message; but is seems as though it always adds the header information as lower case. Is there a way to tell mapi to ignore the case? In other words if I add a header like "X-MyHeader" it will show up as "x-myheader". Thanks, Tom - "Dmitry Streblechenko" wrote: [Quoted Text] > 1. Read MailItem.MAPIOBJECT property > 2.

Re: Adding a header item with MAPI "Dmitry Streblechenko" <dmitry[ at ]dimastr.com> 1/8/2007 6:42:00 PM AFAIK that's just what the SMTP provider does. Why is this important? According to all the RFCs MIME headers are not case sensitive.

Re: Adding a header item with MAPI Tom at GSD 1/8/2007 6:54:03 PM Oh! Okay. I noticed that all the other header elements were not lower case - that is why I asked. I don't think it will matter; but I had to ask the question. Thanks, Tom - "Dmitry Streblechenko" wrote: [Quoted Text] > AFAIK that's just what the SMTP provider does. > Why is this important?
