使用Mapi发送邮件并回复多封电子邮件

Send mail with Mapi with reply-to multiple emails

本文关键字：回复电子邮件 Mapi 使用更新时间：2023-10-16

我正在使用C++中的MAPI库发送电子邮件。现在我需要我发送的电子邮件有一个回复设置为多封电子邮件，我只需要对一封电子邮件进行回复。

我已经读到，为了能够做到这一点，我需要使用对象FLATENTRYLIST（链接）和FLATENTRY（链接）。我的疑问是如何在FLATENTRYLIST中存储多个FLATENTRY对象。我在C++方面的经验不是很丰富，所以如果有人能帮助我，我会感激的。

提前感谢

FLATENTRYLIST具有cEntries成员，用于确定列表中的条目数。您只需要将条目存储在abEntries数组中。

这是我开发的解决方案-http://www.codeproject.com/KB/IP/CMapiEx.aspx?msg=3959770#xx3959770xx

感谢德米特里的帮助。

当我将EntryID复制到FlatEntry时，我复制了错误的字节数。这是最后一个像符咒一样工作的代码。
