[AccessD] CDO Windows Handles

Yes, thanks Gustav,
I think that is a good solution.  BCC myself in and when that comes through
then I will know it has gone. However, from what you are saying, there is no
way that I can tell whether or not the SMTP Sever has taken it.

Perhaps I should have just expanded a bit on my problem.  We are trying to
capture this funcitionality in VB6 and once the user has click on SEND
EMAIL, it runs CDO and then exits the program.  This works ok in Access 3K
but not in VB6. Having run the cdo bit it then errors out when trying to
exit the program.  The person running it has a dial-up connection which is
terribly slow and for a large email attachment it can take some time, but no
way of  knowing how  long unless we divide the attachment size by say,
3Kbytes and then add a safety margin and then close down.  I guess we could
minimize the app while it was doing this and as long as the user didn't
switch off or drop the dial-up then it should work.

Thanks a million.
Max

Hi Max

You wouldn't know. That process runs asynchronously. CDO delivers the mail
to the SMTP server - this will normally not fail except for disk I/O
failures - and from that point on the delivery is in the hands of the SMTP
server. Should delivery fail, it will try a couple of times more, the
receiver may be busy and request a delay and retry. This can take days and
you wouldn't wish to wait for that.
What you can do is to pick up a failure of delivery note from the SMTP
server, or you may somehow study the log file of the SMTP server which is a
task on its own.
Or - if you wish a quick positive feedback - set yourself (the application
or system) as Bcc receiver on the mails you send, pick these up as they come
in and mark those missing. However, you will only see what has been sent how
and when, but not wether the mails actually reached the recipient.

Can anybody advise/help here please.
I am using CDO to send emails and it works just fine BUT I can never tell
when it has finished.
What it does on the "cdo.send" is to pause for a second or two and then
return to the statement following that line BUT I don't think it has
actually sent it at that point. I think it has just "handed it over" to the
system task scheduler (or something like that).
I need to know that the actually event has truly finished.  If it was a
Shell I was using I could grab the handle, but as it is just a build-in
function within the CDO events, this is not possible.
Can anybody throw any light on this?
Thanks
Max
