推荐答案

您应该每次都使用真正的COM对象，而不要使用像
这样的宏. hr = msg-> put_TextBody(L"xxxxxxx");

创建一个真实的文本CComVariant(.

您是否检查了所有错误，例如

hr = msg-> put_Configuration(config);

这是关键任务"和最佳实践"，还是我应该使用CAPS;-)

you should use everytime real COM-Objects, and not such macros like in
hr = msg->put_TextBody(L"xxxxxxx");

create a real textual CComVariant(.

Did you check every error, like

hr = msg->put_Configuration(config);

it is "mission critical" and "best practice" or should I use CAPS ;-)

    Flds->Item[_variant_t("http://schemas.microsoft.com/cdo/configuration/sendpassword")]->Value = _variant_t("password") ;
    Flds->Update();

    /*
    ** These string constants are available in the cdosys.h header file,
    ** but are not put in the cdosys.tlh file when #import runs.

       const BSTR cdoSMTPServer = = L"http://schemas.microsoft.com/cdo/configuration/smtpserver";

       and so on additionally for each of these:

       cdoSMTPServer
       cdoSMTPAccountName
       cdoSMTPAuthenticate
       cdoSendUsingMethod    (You can use the CdoSendUsing enumeration for this.)
       cdoSMTPServerPort
       cdoSendEmailAddress
       cdoSendUserName
       cdoSendPassword
       cdoSendUserReplyEmailAddress
    **
    */

    iMsg->Configuration = iConfig;

    // ... Compose message; add attachments and so forth.

    iMsg->Send();

  }
  CoUninitialize();
}

我认为您错过了cdoSendEmailAddress，并将发件人的邮件放在cdoSendUserName中.当然，如果不调试计算机中的代码，我将无法确认或反驳这一假设.;)
希望这会有所帮助，

I think you missed cdoSendEmailAddress, and put the sender''s mail in cdoSendUserName. Of course, I cannot confirm or disprove this assumption without debugging the code in your machine... ;)
Hope this helps,
