    index.iVal = 1; // value
    index.vt = VT_I2; // type of variant = integer
    BSTR StoragePtr;

    spAttachments->Item (index, &spAttachment);

    spAttachment->get_FileName (&StoragePtr);
    MessageBoxW (NULL, (LPCWSTR)StoragePtr, L"Attached File Name", MB_OK);

推荐答案

我想知道你是如何解决这个问题的？我最近遇到了它。

这是一个错误吗？

I wonder how you solve the problem? I met it recently.
Is it a bug?

哦，我找到了解决问题的方法!!

只需删除：CComQIPtr< outlook :: attachment xmlns：outlook =＃unknown> spAttachment;

进入for循环。



我认为方法Item在发现它不是NULL时拒绝覆盖spAttachment

Oh, I've found a way to figure it out!!
Just Remove : CComQIPtr<outlook::attachment xmlns:outlook="#unknown"> spAttachment;
into for loop.

I think method "Item" refuse to overwrite spAttachment when he found it's not NULL
