OnFileSendMail with two attachments?

Environment: VC++ 4.0, Win 95
Each document in my application is an image file and for each
file/document there is also a text file with the same name but
different suffix. Example:
Document file: MRI001.JPG has a corresponding MRI001.TXT
Any idea or sample code of how can I implement OnFileSendMail()
which will attach both files to the mail message?
The code for that, which can be found in DocMapi.cpp, is very
confusing and I am sure that it is a simpler way to deal with that.
Is there any sample of how to use simple MAPI in a MFC application
to send several files as attachments?

For a free alternative to the MAPI API which is portable to other =
platforms, check out the API defined in xcmc*.h. The cmc_send_documents =
function looks like what you want.

Actually, the code in DocMapi.cpp is really not that bad to modify once
you figure out what it is doing. To do so, here's a quick tour of the
code in CDocument::OnFileSendMail():
1) Locate the MAPISendMail function (everything up to the declaration of
bRemoveTemp)
2) Determine a file name for the current document by using the document
if it is saved and a temporary file if it has not been.
3) Determine a title for the file by using the current doc template
After this: szTempName(A) holds the name of the file which is to be
attached. szTitle(A) has the title for the file.
4) Fill in a MapiFileDesc structure for the file to be attached
5) Create a MapiMessage structure and point it to the MapiFileDesc
structure.
6) Call MAPISendMail (with some MFC magic around it to keep the window
states happy
7) Cleanup and delete any temp file created in step 2.
So, if you wanted to send more than one file in the attachment, you
would declare
MapiFileDesc fileDesc[2];
And then fill in the structure for the files
memset(&fileDesc, 0, sizeof(fileDesc));
fileDesc[0].nPosition = (ULONG)-1;
fileDesc[0].lpszPathName = szTempName;
fileDesc[0].lpszFileName = szTitle;
fileDesc[1].nPosition = (ULONG)-1;
fileDesc[1].lpszPathName = szTempName1;
fileDesc[1].lpszFileName = szTitle1;
You would also have to set the nFileCount field to the actual number of
files you attached.
message.nFileCount = 2;
Note that the nPosition field is pretty important. What it tells MAPI
is where in the document you want the file to be attached. I played
around with this and discovered that if you want to attach to the end of
the document, any trailing \n characters are trimmed from the message
text, causing the attachment to fail. I solved this by putting in a
space as the last character.
message.lpszNoteText = "This is the text\nAnd here is the attachment:
";
fileDesc[0].nPosition = strlen(message.lpszNoteText)-1;
I ended up overriding this function and cutting/pasting the code from
DocMapi into my function and then modified it to take a string for the
contents of the message as well as the list of files to send. You don't
have to go through the work of steps 2 and 3 (which are the bulk of the
function) if you have a file that you know exists and you want to send
it.
If you want fancier control (such as fonts and the like), you will have
to skip past Simple MAPI and go to the full blown MAPI interface (with a
much steeper learning curve).
Enjoy.

Try to look on books online of your Visual C++ under:
SDKs \ Win32 SDK \ Win32 Messaging (MAPI) \ MAPI Programmer's Reference \ Guide \ Programming with Simple MAPI
Here there is some little example of how to use Simple MAPI, that are used by MFC to send mail
(You can also watch at the file "Docmapi.cpp", in the MFC source files to see how Send Mail is implemented).
What you need is to understand how to integrate Simple MAPI in your application and how to use the following MapiMessage structure:
typedef struct {
ULONG ulReserved;
LPTSTR lpszSubject;
LPTSTR lpszNoteText;
LPTSTR lpszMessageType;
LPTSTR lpszDateReceived;
LPTSTR lpszConversationID;
FLAGS flFlags;
lpMapiRecipDesc lpOriginator;
ULONG nRecipCount;
lpMapiRecipDesc lpRecips;
ULONG nFileCount;
lpMapiFileDesc lpFiles;
} MapiMessage, FAR *lpMapiMessage;
Above all the last member of the structure is what you need:
lpFiles
Points to an array of MapiFileDesc structures, each containing information about a file attachment.
Hope this help
