Question

I’m using VS2008 & C++ and I’m trying to create a command line program that sends an email.
I’ve looked on line and found some sample programs but none will compile for me.
Does anyone have an example program for me?
Thanks

This code compiles & runs for me – after figuring out the right headers etc. Still needs command line handling, and the use of the MAPI libraries is deprecated, but what do you want for free? Original code from codeproject.com

#include "windows.h"
#include "tchar.h"

#include "mapi.h"
#include "assert.h"
#define ASSERT assert
#define VERIFY assert

BOOL SendMail(CHAR *lpszFrom, CHAR *lpszTo, CHAR *lpszSubject, CHAR *lpszMessage)
{
   BOOL bSent = FALSE;

   HINSTANCE hMAPI = ::LoadLibrary(_T("mapi32.dll"));
   if(0==hMAPI) return bSent;

   typedef ULONG (FAR PASCAL *PFN_MAPILogon)(ULONG,LPTSTR,LPTSTR,FLAGS,ULONG,LPLHANDLE);
   typedef ULONG (FAR PASCAL *PFN_MAPISendMail)(LHANDLE,ULONG,lpMapiMessage,FLAGS,ULONG);
   typedef ULONG (FAR PASCAL *PFN_MAPILogoff)(LHANDLE,ULONG,FLAGS,ULONG);

   PFN_MAPILogon MAPILogon = (PFN_MAPILogon)::GetProcAddress(hMAPI,"MAPILogon");
   PFN_MAPISendMail MAPISendMail = (PFN_MAPISendMail)::GetProcAddress(hMAPI,"MAPISendMail");
   PFN_MAPILogoff MAPILogoff = (PFN_MAPILogoff)::GetProcAddress(hMAPI,"MAPILogoff");

   const BOOL bFunctionsLoaded = (0!=MAPILogon)&&(0!=MAPISendMail)&&(0!=MAPILogoff);
   ASSERT(bFunctionsLoaded);

   if(bFunctionsLoaded)
   {

      LHANDLE session = 0;
      VERIFY(SUCCESS_SUCCESS==MAPILogon(0,0,0,MAPI_NEW_SESSION,0,&session));
      ASSERT(0!=session);

      MapiRecipDesc recipient;
      ::ZeroMemory(&recipient,sizeof(recipient));
      recipient.ulRecipClass = MAPI_TO;
      recipient.lpszName = lpszTo;

      MapiMessage message;
      ::ZeroMemory(&message,sizeof(message));
      message.lpszSubject = lpszSubject;
      message.lpszNoteText = lpszMessage;
      message.nRecipCount = 1;
      message.lpRecips = &recipient;

      bSent = SUCCESS_SUCCESS == MAPISendMail(session,0,&message,0,0);

      VERIFY(SUCCESS_SUCCESS==MAPILogoff(session,0,0,0));

   }

   ::FreeLibrary(hMAPI);

   return bSent;
}

int _tmain(int argc, _TCHAR* argv[])
{
   SendMail("from_you@go_daddy.com","[e-mail]","Test subject","New Message");
    return 0;
}
