Hi,

I have a question regarding the retrieving of this property. I specify an
array of
SizedSPropTagArray that includes PR_ATTACH_SIZE, PR_HASATTACH,
PR_MESSAGE_SIZE and etc... Next, after I done all the HrQueryRow and get all
the messages I want, I noticed that when I retrieve the PR_ATTACH_SIZE, it
gives me a very huge size such as 2147746063. I know this value is not
correct because it is larger than my PR_MESSAGE_SIZE. I have no problem
obtaining PR_MESSAGE_SIZE and PR_HASATTACH. Is there any problem with this
property? I believe the way to retrieve PR_ATTACH_SIZE is the same as
PR_MESSAGE_SIZE. If I can retrieve PR_MESSAGE_SIZE correctly then obtaining
PR_ATTACH_SIZE should be no problem right??

Btw, do I need to an OpenAttach before able to obtain PR_ATTACH_SIZE? I
don't think so. What's your view?

My objective is to filter away the file attachment if it is too huge (i.e.
greater than certain size).

Many thanks!!

2147746063 is 0x8004010F, which is MAPI_E_NOT_FOUND error.
How do you retrieve the property? If the property cannot be retrieved,
MAPI_W_ERRORS_RETURNED is returned by GetProps() and the returned property
is reset to PT_ERROR. SPropValue.Value.err is then set to the appropriate
error.
AFAIK that property is calculated when the attachment and message are saved,
they are not available before that.

Hi,

Just to share with you my findings. To my horror, I realised that you need
to do a GetAttachmentTable and then followed by HrQueryRow with appropriate
SizedSPropTagArray before able to get the PR_ATTACH_SIZE. But......why is
that so?? It is not mentioned in SDK (if I remember correctly).

As of what I understand, SDK describes this property as "the sum, in bytes,
of the sizes of all properties on an attachment". I may be wrong to assume
that it returns the total size of all attachments!!! What do you think?

Maybe it is just a single attachment and then by doing HrQueryRow and
retrieve the PR_ATTACH_SIZE you get the size of individual attachment if
there is more than one. Please correct me if I am wrong.

Thanks for your time once again!!

Hi,

Btw, I would like to know how do you interpret the error message?

For example 2147746063 is translated to it equivalent HEX value of
0x8004010F. Where do you get the MAPI_E_NOT_FOUND header file inorder to map
0x8004010F to something error message?

If I remember correctly, I ever come across an article that describe
certains bytes of the error message represent certain things but I forgot
where is it.

Most errors are defined in mapicode.h and edkmdb.h.
