Subject: CDO 1.2.1 memory leak, Using GetNext()
> I can't eliminate a memory leak : While looping through the Inbox
> Message list using GetFirst() .. GetNext()
>
> I'm developing a Visual C++ application on NT Workstation 4.0
>
> I tried using Purify to help debug this: it showed about a 500 byte leak
> in GetNext() for every extra message beyond the 1st one (i.e., I get no
> leaks when there's only 1 message in the inbox, but there seems to be a
> leak for every call to GetNext() ). The Task manager indicates a growth
> of about 4K for every pass through the Inbox.
> This is not acceptable for our operating conditions.
>
> I have a while (messages) loop embedded in a forever loop. I sleep a
> user-specified delay between every loop cycle.
>
> My purpose for the forever loop is to continuously monitor the inbox for
> messages which come from various sources at random times.
>
> I also tried the code from Knowledge base article Q171429 with the same
> result. They use essentially the same logic, except they don't have the
> forever loop. I close all the CDO objects, but do not logout or
> disconnect the MAPI session each pass. Maybe I should do this
> periodically?

> MessagesPtr pMessages = pFolder->Messages;
>
