Hi,

I'm trying to read e-mail attachments by following instructions at:
http://msdn.microsoft.com/enus/library/ms838293.aspx#ppc_2002part3_topic3

I get attachment size from PR_ATTACH_SIZE properly. When I call OpenAttach
it succeeds and gives me an IStream pointer. But stream size is 0 and if I
try to read I just get success with 0 bytes every time I read.

I also tried different things like getting PR_ATTACH_METHOD but this does
not appear to be set.

I try to open the stream as follows:
hr = pAttachment->OpenProperty(PR_ATTACH_DATA_BIN, &IID_IStream,
STGM_READ, 0, (IUnknown**)&pStream);

Does anyone have an example or how to read e-mail attachments or know what
the catch is?

I also need to get attachment mime type but none of the PR_ATTACH_MIME_TYPE
properties seem to be set.

I'm working on WM 5.0 with C++

Thanks much!
Mihaela

According to the documentation the second and third arguments should not be
used on Windows CE e.g.
hr = pAttachment->OpenProperty(PR_ATTACH_DATA_BIN, NULL, NULL, 0,
(IUnknown**)&pStream);

The stream returned from this function does not support length, you have to
just keep reading until there is no more data.

ok thanks. Also the attachment was not downloaded so I had to download it
(kind of obvious but I missed that at first).
