Может ли ваше программное обеспечение требовать MAPI ? Это интерфейс, который обеспечивает довольно простой интерфейс для любой пользовательской программы электронной почты по умолчанию.
Если это так, то вы можете использовать что-то вроде следующего:
/////////////////////////////////////////////////////////
// CMapiSendMessage
// Allows for simplified message generation and transmission using Simple MAPI
class CMapiSendMessage
{
public:
// constant data
enum RecipientType { FROM = MAPI_ORIG, TO = MAPI_TO, CC = MAPI_CC, BCC = MAPI_BCC };
// ctors
CMapiSendMessage() { }
// accessors
CString GetSubject() const { return m_subject; }
CString & GetMessage() { return m_message; }
const CString & GetMessage() const { return m_message; }
// setters
void AddRecipient(RecipientType type, const CStringA & strName, const CStringA & strAddress = "")
{
m_recipients.push_back(Recipient(type, strName, strAddress));
}
void SetSubject(const CString & strSubject)
{
m_subject = strSubject;
}
void SetMessage(const CString & strMessage)
{
m_message = strMessage;
}
void AddAttachment(const CFilename & filename)
{
m_attachments.push_back(filename.cstring());
}
// actions
ULONG Send(bool bShowDialog, HWND hwndParent); // send this message, show or don't show the user the message dialog
// returns SUCCESS_SUCCESS if all went well
// returns MAPI_USER_ABORT if user aborted the send
// returns MAPI_E_LOGIN_FAILURE if unable to login to MAPI service (user login failed)
ULONG AfxSend(bool bShowDialog, bool bShowError); // send message with special processing for an MFC application
// set bShowError if you wish to automatically show standard MFC error messages if the send message failed
protected:
// types
struct Recipient
{
RecipientType type;
CStringA name;
CStringA address;
Recipient(RecipientType _type, const CStringA & _name, const CStringA & _address = "") :
type(_type), name(_name), address(_address)
{
}
// force default ctor to set type to zero (not random)
Recipient() : type(FROM) { }
};
typedef std::vector<Recipient> RecipientVector;
typedef std::vector<CString> AttachmentVector;
CMailAPI32 m_api; // MAPI interface
RecipientVector m_recipients; // recipients (TO:, CC:, and BCC:)
CString m_subject; // message subject
CString m_message; // message body text
AttachmentVector m_attachments; // file attachments
};
И половина CPP:
typedef std::vector<CMapiRecipDesc> MapiRecipDescVector;
typedef std::vector<CMapiFileDesc> MapiFileDescVector;
//////////////////////////////////////////////////////////////////////

Это из моей кодовой базы - и я не пытаюсь распутать его из моих собственных библиотек Но вы должны быть в состоянии «заполнить пробелы».
Удачи!
