MFC里用MAPI发送邮件时如何设置CC。

以下是我发送邮件的代码。请帮我加上CC给aa@qq.com。谢谢了。分可以追加！我在网上搜了下说用IMessage的一个方法去设置，可是不会用。高手们帮帮忙！
LHANDLE loghandle;
ULONG res = m_MAPILogon( 0,NULL,NULL,0,0,&loghandle );
CString ss;
ss.Format( "%d",res );
CString strsubject,strbody;
strsubject = mailSubject;
strbody = mailBody;
CTime time = CTime::GetCurrentTime();
CString strtime = time.Format( "%y//%m//%d//%H" );
CString address1,address2;
address1 = user
address2 = "SMTP:" + user + "@qq.com";
MapiMessage message;
//subject of the mail
message.lpszSubject = strsubject.GetBuffer(0);
//body of the mail
message.lpszNoteText = strbody.GetBuffer(0);
message.lpszMessageType = NULL;
//time sending
message.lpszDateReceived = strtime.GetBuffer(0);

message.lpszConversationID = NULL;
message.flFlags = MAPI_SENT;
//sender message
message.lpOriginator = NULL;
message.nRecipCount = 1;//reciver count
MapiRecipDesc reci = { 0,MAPI_TO,address1.GetBuffer(0),address2.GetBuffer(0),0,NULL };
message.lpRecips = &reci;
message.lpFiles = 0;//attachment
message.nFileCount = 0;//attachment count

int lresult = m_MAPISendMail( loghandle,0,&message,0,0); //发送邮件

m_MAPIFreeBuffer( &message );
m_MAPILogoff( loghandle,0,0,0 );
你们都错了。这个方法我当然试过。
MapiRecipDesc reci[1];
reci[0] = { 0,MAPI_TO,address1.GetBuffer(0),address2.GetBuffer(0),0,NULL };
reci[1] = { 0,MAPI_CC,"aa","aa@qq.com",0,NULL };
message.lpRecips = &reci;
这些地方都会报错。MapiRecipDesc 是个结构体。

用这个吧。简单明了。

我以前写过这方面的。楼主还有问题都可以问问吧。今天看你发了2次问题了。

MapiRecipDesc reci[1];定义一个元素的数组，这么简单的基础知识。。。后面的reci[1]访问越界。你还是好好去看看基础吧。没学行就学飞只会摔得更疼。 再看看别人怎么说的。

这个改动很简单的： LHANDLE loghandle; ULONG res = m_MAPILogon( 0,NULL,NULL,0,0,&loghandle ); CString ss; ss.Format( "%d",res ); CString strsubject,strbody; strsubject = mailSubject; strbody = mailBody; CTime time = CTime::GetCurrentTime(); CString strtime = time.Format( "%y//%m//%d//%H" ); CString address1,address2; address1 = user address2 = "SMTP:" + user + "@qq.com"; MapiMessage message; //subject of the mail message.lpszSubject = strsubject.GetBuffer(0); //body of the mail message.lpszNoteText = strbody.GetBuffer(0); message.lpszMessageType = NULL; //time sending message.lpszDateReceived = strtime.GetBuffer(0); message.lpszConversationID = NULL; message.flFlags = MAPI_SENT; //sender message message.lpOriginator = NULL; //改收件人计数 message.nRecipCount = 2;//reciver count //建立收件人地址数组 MapiRecipDesc reci[1]; reci[0] = { 0,MAPI_TO,address1.GetBuffer(0),address2.GetBuffer(0),0,NULL }; reci[1] = { 0,MAPI_TO,"aa","aa@qq.com",0,NULL }; message.lpRecips = &reci; message.lpFiles = 0;//attachment message.nFileCount = 0;//attachment count int lresult = m_MAPISendMail( loghandle,0,&message,0,0); //发送邮件 m_MAPIFreeBuffer( &message ); m_MAPILogoff( loghandle,0,0,0
