如何以編程方式將帶有附件的電子郵件發送給使用C++中的MAPI的已知收件人？ MAPISendMail（）

Question

This question是類似的，但不顯示如何添加收件人。

我該怎麼做？

我們想最廣泛的支持可能是很多Windows平臺，儘可能（從XP及更高版本）

我們使用Visual Studio 2008

本質上講，我們希望與發送電子郵件：

• 預填充目的地址
• 文件附件
• 主題行

從我們的程序，並賦予用戶添加任何信息或取消它的能力。

編輯 我想使用MAPISendMail則（） 我複製多從靠近頂部鏈接問題的代碼，但我沒有得到任何電子郵件DLG框和返回的錯誤，我從電話得到的是：0x000f - 「該系統找不到指定的「驅動

如果我註釋掉線設置收件人，它工作正常（當然後來我也沒有收件人預先填寫）

下面是代碼：

#include <tchar.h> 
#include <windows.h> 
#include <mapi.h> 
#include <mapix.h> 

int _tmain(int argc, wchar_t *argv[]) 
{ 
    HMODULE hMapiModule = LoadLibrary(_T("mapi32.dll")); 

    if (hMapiModule != NULL) 
    { 
     LPMAPIINITIALIZE lpfnMAPIInitialize = NULL; 
     LPMAPIUNINITIALIZE lpfnMAPIUninitialize = NULL; 
     LPMAPILOGONEX lpfnMAPILogonEx = NULL; 
     LPMAPISENDDOCUMENTS lpfnMAPISendDocuments = NULL; 
     LPMAPISESSION lplhSession = NULL; 
     LPMAPISENDMAIL lpfnMAPISendMail = NULL; 

     lpfnMAPIInitialize = (LPMAPIINITIALIZE)GetProcAddress(hMapiModule, "MAPIInitialize"); 
     lpfnMAPIUninitialize = (LPMAPIUNINITIALIZE)GetProcAddress(hMapiModule, "MAPIUninitialize"); 
     lpfnMAPILogonEx = (LPMAPILOGONEX)GetProcAddress(hMapiModule, "MAPILogonEx"); 
     lpfnMAPISendDocuments = (LPMAPISENDDOCUMENTS)GetProcAddress(hMapiModule, "MAPISendDocuments"); 
     lpfnMAPISendMail =  (LPMAPISENDMAIL)GetProcAddress(hMapiModule, "MAPISendMail"); 

     if (lpfnMAPIInitialize && lpfnMAPIUninitialize && lpfnMAPILogonEx && lpfnMAPISendDocuments) 
     { 
      HRESULT hr = (*lpfnMAPIInitialize)(NULL); 

      if (SUCCEEDED(hr)) 
      { 
       hr = (*lpfnMAPILogonEx)(0, NULL, NULL, MAPI_EXTENDED | MAPI_USE_DEFAULT, &lplhSession); 

       if (SUCCEEDED(hr)) 
       { 
        // this opens the email client 
        // create the msg. We need to add recipients AND subject AND the dmp file    

        // file attachment 
        MapiFileDesc filedesc;    
        ::ZeroMemory(&filedesc, sizeof(filedesc));     
        filedesc.nPosition = (ULONG)-1; 
        filedesc.lpszPathName = "E:\\Development\\Open\\testmail\\testmail.cpp";  

        // recipient(s) 
        MapiRecipDesc recip; 
        ::ZeroMemory(&recip, sizeof(recip));   
        recip.lpszName = "QA email"; 
        recip.lpszAddress = "qa@myaccount.com"; 

        // the message 
        MapiMessage msg; 
        ::ZeroMemory(&msg, sizeof(msg)); 
        msg.lpszSubject  = "Test"; 
        msg.nRecipCount  = 1; // if I comment out this line it works fine...     
        msg.lpRecips  = &recip;          
        msg.nFileCount  = 1; 
        msg.lpFiles   = &filedesc;     

        hr = (*lpfnMAPISendMail)(0, NULL, &msg, MAPI_LOGON_UI|MAPI_DIALOG, 0); 

        if (SUCCEEDED(hr)) 
        { 
         hr = lplhSession->Logoff(0, 0, 0); 
         hr = lplhSession->Release(); 
         lplhSession = NULL; 
        } 
       } 
      } 

      (*lpfnMAPIUninitialize)(); 
     } 

     FreeLibrary(hMapiModule); 
    } 

    return 0; 
}

O ops - 我忘了設置

recip.ulRecipClass = MAPI_TO; 

現在很好用。
