Capturing outlook events not working with C++

[Chuck Bohling]

I'm trying to capture outlook events using the object model and C++. I
successfully set an IConnectionPoint::Advise sink for outlook's
ApplicationEvents. I get Startup, NewMail, etc. events just as expected.
However, when I try to set an Advise sink for a MAPIFolder's FolderEvents,
nothing happens. No events are sent. I've checked to make sure I have the
correct folder. Everything seems ok. There are no errors in the code that
sets the sink. In fact, my sink's QueryInterface is called, with
IID_IDispatch. It looks like it should work but doesn't. Anyone have any
thoughts. Here the code. Thanks.

_ApplicationPtr app = g_dispatch; // from outlook
_NameSpacePtr ns = app->GetNamespace("MAPI");
MAPIFolderPtr folder = ns->GetDefaultFolder(olFolderInbox);
MAPIFolderPtr subFolder = folder->Folders->Item(1);

_FoldersPtr folders = subFolder->Folders;

IConnectionPointContainerPtr connectionPointContainer = folders;
if (connectionPointContainer != NULL)
{
IConnectionPoint *connPoint = NULL;
connectionPointContainer->FindConnectionPoint(__uuidof(FoldersEvents),
&connPoint);
IConnectionPointPtr connectionPoint = connPoint;

if (connectionPoint != NULL)
{
ULONG cookie;
SQFoldersEventsPtr events = new SQFoldersEvents;
connectionPoint->Advise(events, &cookie);
}
}

Do you keep the folders variable alive at all times? Or is it a local
variable?

You got it. The connectionpoint smartptr's were local and went out of scope.
I did the same with the applicationevents but for some reason, those
smartptr's stayed around. I discovered the problem by trying to unadvise in
some other piece of code.

Thanks

BTW, outlookspy is fabulous!!

Yep, Outlook used to always return the same instance of the Application
object, that's why it worked. I think they finally fixed it in 2003, so your
code trapping the Application events would break there too.
