Emailing (alt. to MAPI)

I would like to send an email within my VC++ Win32 app.
It seems MAPI uses Exchange. Is there any classes out there
for emailing?
One which will let me attach a file, and use a proxy?
MAPI seems like it might work if Exchange is set up for
a proxy.. But I'd rather not have to worry about Exchange being set up, on top of my own app.

Simply use 'ShellExecute()' and supply 'mailto:<recipient>?<subject>' as the 'lpFile' parameter. This will start the default mailer application.

I would like to send the email --within-- my C++ program.
Is there any classes or such which will let me do this without launching external programs?
I'm doubtfull, but just incase...

Otherwise, I could use the shellexec..or MAPI. Both of these require the default (or Exchange) mailing app. to be configured and setup properly.
I guess one difference between these two methods is that with MAPI I would have to ensure Exchange is runnable on every computer I run my app on, while shellexec just takes the default.

Yes, that's the problem ... but MAPI also relies on a properly configured MS Exchange...

The big problem with shellexecute is that the mailing app is executed, and then user interaction is needed. MAPI allows me to send the message automatically.
The app I am making is automated. Emails are sent out without needing user interaction.

i.e: When you register over the net, and the reg. number is sent automatically via email after processing (automatically) to you..How was that email sent do you suppose?

I remember there are SMTP and POP3 classes somewhere in www.codeguru.com - take a look.

This should do it all for you:

////////////////////////////////////////////////////////
// Compose message
CString csSubject = "Email Test";
CString csText = "\nIt's SO great to be programming today!\n"
"Thank you for your time!\n";

////////////////////////////////////////////////////////
// Load the DLL

HINSTANCE hInstMail = ::LoadLibraryA("MAPI32.DLL");
if(hInstMail == NULL)
{
AfxMessageBox(AFX_IDP_FAILED_MAPI_LOAD);
return;
}
ASSERT(hInstMail != NULL);

/* Logon (and Logoff) only needed if a session is not started or
you want to send from a diffrent profile

////////////////////////////////////////////////////////
// Create function pointer to 'MAPILogon' & Logon

ULONG (PASCAL *lpfnLogon)(ULONG, LPTSTR, LPTSTR, FLAGS, ULONG, LPLHANDLE);
(FARPROC &)lpfnLogon = GetProcAddress(hInstMail, "MAPILogon");

lpfnLogon(NULL, "Session", "Password", 0, 0, &lhSession);

*/
////////////////////////////////////////////////////////
// Create function pointer to 'MAPISendMail'

ULONG (PASCAL *lpfnSendMail)(ULONG, ULONG, MapiMessage *, FLAGS, ULONG);
(FARPROC &)lpfnSendMail = GetProcAddress(hInstMail, "MAPISendMail");

if(lpfnSendMail == NULL)
{
AfxMessageBox(AFX_IDP_INVALID_MAPI_DLL);
return;
}


////////////////////////////////////////////////////////
// Set up MAPI structs

// Who's sending this email???
MapiRecipDesc MapiFrom;
memset(&MapiFrom, 0, sizeof(MapiFrom));
MapiFrom.ulRecipClass = MAPI_ORIG;
MapiFrom.lpszName = "Big Cheese email sender";
MapiFrom.lpszAddress = "SMTP:BigGuy@myprovider.com";

// Who gets this email???
MapiRecipDesc MapiTo[2]; // Array of recipiants
memset(&MapiTo[0], 0, sizeof(MapiTo[0]));
MapiTo[0].ulRecipClass = MAPI_TO;
MapiTo[0].lpszName = "Big Cheese email receiver #1";
MapiTo[0].lpszAddress = "SMTP:otherguy@hisprovider.com";

// Who else gets this email???
memset(&MapiTo[1], 0, sizeof(MapiTo[1]));
MapiTo[1].ulRecipClass = MAPI_TO;
MapiTo[1].lpszName = "Big Cheese email receiver #2";

Email.lpOriginator = &MapiFrom;
Email.lpRecips = MapiTo;      
Email.nRecipCount = 2;      

// Email.flFlags // various
// Email.lpFiles // pointer to 'MapiFileDesc' struct for attachments
// Email.nFileCount


////////////////////////////////////////////////////////
// Call MAPISendMail

ul = lpfnSendMail(lhSession, 0, &Email, 0, 0);
if(ul == SUCCESS_SUCCESS)
AfxMessageBox("Mail Sent! We're happy!");

/* Logoff (and Logon) only needed if a session is not started or

That looks almost exactly like what I've got. I would like --alternatives to MAPI--.
ie: a SMTP class.

Then maybe I would not be dependent on an Exchange Inbox Profile?

There is one at codeguru, but it doesn't take attachments as yet.

Thanks though..
