¿Cómo enviar un correo electrónico en VC++?

Question

Soy nuevo en VC ++ y programación.

Tengo que escribir el código para enviar un correo electrónico en VC ++.

¿Cómo lo hago? ¡¡Por favor ayuda!!

Answer 1

¿Puede su software requerir MAPI ? Es una interfaz que proporciona una interfaz bastante simple para lo que el usuario haya instalado como programa de correo electrónico predeterminado.

Si es así, entonces puedes usar algo como lo siguiente:

/////////////////////////////////////////////////////////
// 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
};

Y la mitad del CPP:

typedef std::vector<CMapiRecipDesc> MapiRecipDescVector;
typedef std::vector<CMapiFileDesc> MapiFileDescVector;
//////////////////////////////////////////////////////////////////////
// CMailAPI32
//////////////////////////////////////////////////////////////////////
///////////////////////////////////////////////////////////////////////
// CMapiSendMessage
ULONG CMapiSendMessage::Send(bool bShowDialog, HWND hwndParent) // send, show user interface - let them edit the message and have final choice in send/cancel
{
// save the cwd
CPathname cwd(CPathname::GetCurrent());
// build the recipients array
const size_t total_recipients = m_recipients.size();
MapiRecipDescVector recipients(total_recipients);
for (size_t i = 0; i < total_recipients; ++i)
{
CMapiRecipDesc recipient;
recipient.ulReserved = 0L;
recipient.ulRecipClass = m_recipients[i].type;
recipient.lpszName = const_cast<LPSTR>(GetPtrOrNull(m_recipients[i].name));
recipient.lpszAddress = const_cast<LPSTR>(GetPtrOrNull(m_recipients[i].address));
recipient.ulEIDSize = 0;
recipient.lpEntryID = NULL;
recipients[i] = recipient;
}
// build attachments array
const size_t total_attachments = m_attachments.size();
MapiFileDescVector attachments(total_attachments);
for (size_t j = 0; j < total_attachments; ++j)
{
CFilename filename(m_attachments[j]);
if (!filename.Exists())
ThrowLabeledException(FString(_T("File does not exist: %s"), filename.c_str()));
// get the fully specified path
size_t size = filename.cstring().GetLength() + 1;
attachments[j].lpszPathName = new char[size];
#ifdef _UNICODE
_wcstombsz(attachments[j].lpszPathName, filename, size);
#else
lstrcpy(attachments[j].lpszPathName, filename);
#endif
// build an appropriate title for the attachment
CString strTitle = filename.GetFullName();
size = strTitle.GetLength() + 1;
attachments[j].lpszFileName = new char[size];
#ifdef _UNICODE
_wcstombsz(attachments[j].lpszFileName, strTitle, size);
#else
lstrcpy(attachments[j].lpszFileName, strTitle);
#endif
// attachment not embedded in the mapi_msg text;
attachments[j].nPosition = (ULONG)-1;
}
// prepare the mapi_msg
MapiMessage mapi_msg =
{
0, // reserved, must be 0
(LPSTR)GetPtrOrNull(m_subject), // subject
(LPSTR)GetPtrOrNull(m_message), // body
NULL, // NULL = interpersonal mapi_msg
NULL, // no date; MAPISendMail ignores it
NULL, // no conversation ID
0L, // no flags, MAPISendMail ignores it
NULL, // no originator, this is ignored too
total_recipients, // no. recipients
total_recipients ? &recipients[0] : NULL, // array of recipients
total_attachments, // no. attachments
total_attachments ? &attachments[0] : NULL // array of attachments
};
// send mail
FLAGS flags = MAPI_LOGON_UI;
BitSetIf(flags, MAPI_DIALOG, bShowDialog);
ULONG nError = m_api.SendMail(
NULL, // temporary session
(ULONG)hwndParent,
&mapi_msg,
flags,
0
);
// delete the attachment filenames
for (int k = total_attachments; k ; --k)
{
delete [] attachments[k-1].lpszPathName;
delete [] attachments[k-1].lpszFileName;
}
// restore CWD
cwd.SetCurrent();
// indicate if we succeeded or not
return nError;
}
ULONG CMapiSendMessage::AfxSend(bool bShowDialog, bool bReportError)
{
// prepare for modal dialog box
AfxGetApp()->EnableModeless(FALSE);
HWND hWndTop;
CWnd * pParentWnd = CWnd::GetSafeOwner(NULL, &hWndTop);
// some extra precautions are required to use MAPISendMail as it
// tends to enable the parent window in between dialogs (after
// the login dialog, but before the send note dialog).
pParentWnd->SetCapture();
::SetFocus(NULL);
pParentWnd->m_nFlags |= WF_STAYDISABLED;
// attempt to send the message
ULONG nError = Send(bShowDialog, pParentWnd->GetSafeHwnd());
// display error to user
if (nError != SUCCESS_SUCCESS &&
nError != MAPI_USER_ABORT &&
nError != MAPI_E_LOGIN_FAILURE)
{
AfxMessageBox(AFX_IDP_FAILED_MAPI_SEND);
}
// after returning from the MAPISendMail call, the window must
// be re-enabled and focus returned to the frame to undo the workaround
// done before the MAPI call.
::ReleaseCapture();
pParentWnd->m_nFlags &= ~WF_STAYDISABLED;
pParentWnd->EnableWindow(TRUE);
::SetActiveWindow(NULL);
pParentWnd->SetActiveWindow();
pParentWnd->SetFocus();
if (hWndTop != NULL)
::EnableWindow(hWndTop, TRUE);
AfxGetApp()->EnableModeless(TRUE);
// report success or not
return nError;
}

Esto es de mi base de código, y no me estoy esforzando por descifrarlo de mis propias bibliotecas. Pero deberías poder "completar los espacios en blanco".

¡Buena suerte!

Answer 2

Así es como lo hago con las clases de ATL. Creo que necesitas una de las versiones pagas de VC ++ para obtener ATL. Necesitarás el nombre de tu servidor de correo electrónico.

CSMTPConnection smtp;
if (!smtp.Connect(m_strEmailServer))
return false;
// start generating the email message; remember to call CoInitialize somewhere in the app before this
CMimeMessage msg;
msg.SetSubject(m_strSubject);
msg.SetSender(m_strSender);
// repeat the following as necessary
msg.AddRecipient(strSingleRecipient);
msg.AddText(m_strBody);
if (!smtp.SendMessage(msg))
return false;
return true;
