VC++ Example Gmail SMTP server address is "smtp.gmail.com". It requires SSL or TLS connection, and you should use your Gmail email address as the user name for ESMTP authentication. For example: your email is "gmailid@gmail.com", and then the user name should be "gmailid@gmail.com".
// The following example codes demonstrate sending email message using Gmail SMTP server
// To get full sample projects, please download and install EASendMail on your machine.
// To run it correctly, please change SMTP server, user, password, sender, recipient value to yours
Code:
#include "stdafx.h"
#include "easendmailobj.tlh"
using namespace EASendMailObjLib;
int _tmain(int argc, _TCHAR* argv[])
{
::CoInitialize( NULL );
IMailPtr oSmtp = NULL;
oSmtp.CreateInstance( "EASendMailObj.Mail");
oSmtp->LicenseCode = _T("TryIt");
// Set your gmail email address
oSmtp->FromAddr = _T("gmailid@gmail.com");
// Add recipient email address
oSmtp->AddRecipientEx( _T("support@emailarchitect.net"), 0 );
// Set email subject
oSmtp->Subject = _T("simple email from Visual C++ with gmail account");
// Set email body
oSmtp->BodyText = _T("this is a test email sent from Visual C++ project with Gmail");
// Gmail SMTP server address
oSmtp->ServerAddr = _T("smtp.gmail.com");
// If you want to use direct SSL 465 port,
// Please add this line, otherwise TLS will be used.
// oSmtp->ServerPort = 465;
// detect SSL/TLS automatically
oSmtp->SSL_init();
// Gmail user authentication should use your
// Gmail email address as the user name.
// For example: your email is "gmailid@gmail.com", then the user should be "gmailid@gmail.com"
oSmtp->UserName = _T("gmailid@gmail.com");
oSmtp->Password = _T("yourpassword");
_tprintf(_T("Start to send email via gmail account ...\r\n" ));
if( oSmtp->SendMail() == 0 )
{
_tprintf( _T("email was sent successfully!\r\n"));
}
else
{
_tprintf( _T("failed to send email with the following error: %s\r\n"),
(const TCHAR*)oSmtp->GetLastErrDescription());
}
if( oSmtp != NULL )
oSmtp.Release();
return 0;
}

using namespace EASendMailObjLib;
int _tmain(int argc, char* argv[])
{

IMailPtr oSmtp = NULL;
oSmtp.CreateInstance("EASendMailObj.Mail");
oSmtp->LicenseCode = ("TryIt");
// Set your gmail email address

Please try to use "Try-catch" to catch the error information.
It is likely that your trial period is expired, you can re-download the installer from our site and re-install it to get extend trial period.
Code:
int _tmain(int argc, char* argv[])
{
::CoInitialize(NULL);
try
{
IMailPtr oSmtp = NULL;
oSmtp.CreateInstance("EASendMailObj.Mail");
oSmtp->LicenseCode = ("TryIt");
// Set your gmail email address
oSmtp->FromAddr = ("gmailid@gmail.com");
// Add recipient email address
oSmtp->AddRecipientEx(("gmailid@gmail.com"), 0);
// Set email subject
oSmtp->Subject = ("simple email from Visual C++ with gmail account");
// Set email body
oSmtp->BodyText = ("this is a test email sent from Visual C++ project with Gmail");
// Gmail SMTP server address
oSmtp->ServerAddr = ("smtp.gmail.com");
// If you want to use direct SSL 465 port,
// Please add this line, otherwise TLS will be used.
// oSmtp->ServerPort = 465;
// detect SSL/TLS automatically
oSmtp->SSL_init();
// Gmail user authentication should use your
// Gmail email address as the user name.
// For example: your email is "gmailid@gmail.com", then the user should be "gmailid@gmail.com"
oSmtp->UserName = ("gmailid@gmail.com");
oSmtp->Password = ("****");
printf("Start to send email via gmail account ...\r\n");
if (oSmtp->SendMail() == 0)//program crashes here
{
printf("email was sent successfully!\r\n");
}
else
{
printf("failed to send email with the following error: %s\r\n"),
(const TCHAR*)oSmtp->GetLastErrDescription();
}
if (oSmtp != NULL)
oSmtp.Release();
}catch( _com_error &ep )
{
_tprintf( _T("Error: %s"), (const TCHAR*)ep.Description());
}
return 0;
