CE MAPI实例讲解 --- 如何设置收件人信息（五）

       发件人和收件人是邮件和消息很常用的几个属性之一，关于发件人的设置和获取是很简单的，只需要处理PR_SENDER_EMAIL_ADDRESS属性即可，下面主要讲述的收件人的设置和获取。

       MAPI收件人结构如图（摘自MSDN）:

       每一个Entry代表了一个收件人信息组，每个信息组又可以有多项信息组成，举个例子，下面的代码代表了一个收件人的信息：

       aEntries[0].rgPropVals[0].ulPropTag     = PR_RECIPIENT_TYPE;   //类型，MAPI_TO代表是设置到TO字段上的，相应的还有MAPI_CC和MAPI_BCC。

       aEntries[0].rgPropVals[0].Value.ul        = MAPI_TO;

       aEntries[0].rgPropVals[1].ulPropTag    = PR_ADDRTYPE;              //设置地址类型，一般为SMTP

       aEntries[0].rgPropVals[1].Value.LPSZ   = _T("SMTP");

       aEntries[0].rgPropVals[2].ulPropTag    = PR_EMAIL_ADDRESS;   //收件人地址

       aEntries[0].rgPropVals[2].Value.LPSZ = _T("1234567");

       设置收件人是通过IMessage:: ModifyRecipients来实现的，以下的代码举例说明了如何设置TO、CC和BCC属性：

       INT              nRecipientCount    = 3;        //表示有10个联系人信息

       INT               nListBufSize          = CbNewADRLIST(nRecipientCount);       //计算10个联系人需要的存储空间

       LPADRLIST   pAddressList         = NULL;

       MAPIAllocateBuffer(nListBufSize, (LPVOID FAR *)&pAddressList));            //分配空间
       memset(pAddressList, 0, nBufSize);           

       pAddressList->cEntries               = 3;        //表明一共有3个联系人信息

       //设置To

       INT nCurIndex     = 0;

       MAPIAllocateBuffer(sizeof(SPropValue) * 3, (LPVOID FAR *)&pAddressList->aEntries[nCurIndex].rgPropVals));      //分配空间       memset(pAddressList->aEntries[nCurIndex].rgPropVals, 0, sizeof(SPropValue) * 3);

       pAddressList->aEntries[nCurIndex].rgPropVals[0].ulPropTag           = PR_RECIPIENT_TYPE;

       pAddressList->aEntries[nCurIndex].rgPropVals[0].Value.ul               = MAPI_TO;               //表明是写到To

       pAddressList->aEntries[nCurIndex].rgPropVals[1].ulPropTag          = PR_ADDRTYPE;

       pAddressList->aEntries[nCurIndex].rgPropVals[1].Value.LPSZ = _T("SMTP");

       pAddressList->aEntries[nCurIndex].rgPropVals[2].ulPropTag           = PR_EMAIL_ADDRESS;

       pAddressList->aEntries[nCurIndex].rgPropVals[2].Value.LPSZ = _T("1234567");

       pAddressList->aEntries[nCurIndex].cValues = 3;        //表明改联系人有3个属性要设置

       //同上，现在设置CC

       nCurIndex            = 1;

       MAPIAllocateBuffer(sizeof(SPropValue) * 3, (LPVOID FAR *)&pAddressList->aEntries[nCurIndex].rgPropVals));      //分配空间       memset(pAddressList->aEntries[nCurIndex].rgPropVals, 0, sizeof(SPropValue) * 3);

       pAddressList->aEntries[nCurIndex].rgPropVals[0].ulPropTag           = PR_RECIPIENT_TYPE;

       pAddressList->aEntries[nCurIndex].rgPropVals[0].Value.ul               = MAPI_CC;               //表明是写到CC

       pAddressList->aEntries[nCurIndex].rgPropVals[1].ulPropTag          = PR_ADDRTYPE;

       pAddressList->aEntries[nCurIndex].rgPropVals[1].Value.LPSZ        = _T("SMTP");

       pAddressList->aEntries[nCurIndex].rgPropVals[2].ulPropTag           = PR_EMAIL_ADDRESS;

       pAddressList->aEntries[nCurIndex].rgPropVals[2].Value.LPSZ        = _T("7654321");

       pAddressList->aEntries[nCurIndex].cValues = 3;        //表明改联系人有3个属性要设置

       //同上，现在设置BCC

       nCurIndex            = 2;

       MAPIAllocateBuffer(sizeof(SPropValue) * 3, (LPVOID FAR *)&pAddressList->aEntries[nCurIndex].rgPropVals));      //分配空间       memset(pAddressList->aEntries[nCurIndex].rgPropVals, 0, sizeof(SPropValue) * 3);

       pAddressList->aEntries[nCurIndex].rgPropVals[0].ulPropTag           = PR_RECIPIENT_TYPE;

       pAddressList->aEntries[nCurIndex].rgPropVals[0].Value.ul               = MAPI_BCC;            //表明是写到CC

       pAddressList->aEntries[nCurIndex].rgPropVals[1].ulPropTag          = PR_ADDRTYPE;

       pAddressList->aEntries[nCurIndex].rgPropVals[1].Value.LPSZ         = _T("SMTP");

       pAddressList->aEntries[nCurIndex].rgPropVals[2].ulPropTag           = PR_EMAIL_ADDRESS;

       pAddressList->aEntries[nCurIndex].rgPropVals[2].Value.LPSZ         = _T("88888888");

       pAddressList->aEntries[nCurIndex].cValues = 3;        //表明改联系人有3个属性要设置

       //调用ModifyRecipients添加联系人，完了记的释放申请的内存，pMsg为你想操作的Message的对象实例，关于如何获取可以参考以前的文章。       pMsg->ModifyRecipients(MODRECIP_ADD, pAddressList)

       for(INT i = 0; i < nRecipientCount; i++)

              MAPIFreeBuffer(pAddressList->aEntries[i].rgPropVals);

       MAPIFreeBuffer(pAddressList);
