Question

我正在使用VS2008＆amp; C ++和我正在尝试创建一个发送电子邮件的命令行程序我已经上线并找到了一些示例程序，但没有人会为我编译有没有人有我的示例程序？感谢

Answer 1

此代码编译＆amp;为我运行 - 在确定正确的标题后等仍然需要命令行处理，并且不推荐使用MAPI库，但是你想要免费的是什么？来自codeproject.com的原始代码

#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","to.someone@gmail.com","Test subject","New Message");
    return 0;
}

由于您的服务器是Exchange，因此编写程序以发送电子邮件的最方便方法是使用C＃和System.Net.Mail，如演示here。这是C ++ / CLI代码：

   static void CreateTestMessage2( String^ server )
   {
      String^ to = L"jane@contoso.com";
      String^ from = L"ben@contoso.com";
      MailMessage^ message = gcnew MailMessage( from,to );
      message->Subject = L"Using the new SMTP client.";
      message->Body = L"Using this new feature, you can send an e-mail message from an application very easily.";
      SmtpClient^ client = gcnew SmtpClient( server );

      // Credentials are necessary if the server requires the client 
      // to authenticate before it will send e-mail on the client's behalf.
      client->UseDefaultCredentials = true;
      client->Send( message );
      client->~SmtpClient();
   }

如果你真的想使用原生C ++（即不通过C ++ / CLI访问System.Net.Mail），那么你就会遇到一个描述here的原生API。

但是，您可以按照blat所述使用MapiSend或here。
