I am trying to access Outlook message attachments data more
efficiently.

Right now, I am using Redemption.Attachment.SaveAsFile() and then I
load them back in a Stream with ADODB.Stream.LoadFromFile(), but that
adds a significant overhead in read/write time, which I hope I could
avoid. Yes, I know Redemption provides AsText()/AsArray() for
attachments, but these crash [out of memory] when processing large
attachments.

I stumbled on something in the Redemption History which cought my
attention immediately:

All Redemption items have a CopyTo() method which allows to
copy
a Redemption item into any Outlook Object Model or CDO message.

Being able to copy a MailItem into a CDO.Message would mean that I
could access the attachments data using an ADODB.Stream. The problem
is that if I try this litterally, as in this little piece of code:

' "smi" is a Redemption.SafeMailItem
Dim msg As New CDO.Message
Call smi.CopyTo(msg) '-- error

I get the following error:

Run-time error '-2147418113 (8000ffff)':
Method 'MAPIOBJECT' not supported by automation object

What am I getting wrong? I am using "VB6" and "CDO for Windows 2000".
Or is there another way to do what I am trying to do (access
attachment data more efficiently)?

Thanks for your help.
