Problem loading deployed in-process app

I have an app that hooks into Outlook that works fine either as an exe file,
or as an in-process server in the development environment (very cool and
very easy!), but it doesn't do so well as a DLL.  When Outlook tries to load
it, it always dies.  I've included the first error below (there are also
some follow-on DNU errors that appear to result from the first).  This is my
first stab at creating any sort of in-process app, so I could have
overlooked just about anything.  Any ideas on how to resolve it would be
appreciated greatly!

Thanks,

Don

When deploying as a DLL the default SessionManager is AXDllSessionManager,
which is not a subclass of GUISessionManager, and does not contain the
necessary glue to initialize the windowing system. Hence when you try to
open a window in your DLL it fails. The easiest way to achieve what you are
trying to do is probably to add a custom subclass of GUISessionManager which
selectively overrides SessionManager messages in the same way that
AXDllSessionManager does, with the obvious exception of #startUI which
should use the GUISessionManager implementation.

Aha!  I suppose a modicum of thought about what was staring me in the face
in the class hierarchy might have clued me in sooner.  If it's just a matter
of creating a new subclass of GUISessionManager that implements the eight
instance-side and three class-side methods of AXDllSessionManager, that
should be short work.

By the way, this is the first time I've tried a COM implementation, and even
with a near complete ignorance of the subject, it was amazingly easy--even
straightforward.  DST is just so much nicer than anything Microsoft has to
offer.  Very nice work OA!

Thanks for the help,

Don

HA!  That was pathetically easy.  Thanks to the miracle of drag-and-drop,
the extremely useful Inheritance Chain feature, and Smalltalk's inherent
superiority to all other environments (IMHO ;-), it took about 10 minutes to
register a resounding success.

Thanks again, Blair!

Don

In case anyone is curious (or silly) enough to try this, I've included the
contents of a .CLS file for GUIAXDllSessionManager, a subclass of
RuntimeSessionManager that you can use for DLL's that use the windowing
system.

Have fun,

Don

I ran into this one early on too.  The project seems to have gone away (it
did so even before we figured out what was wrong), but the same thing will
no doubt arise again.  My vote would be to include something like this in
the DLL deployment kit.

Have a good one,

Bill

I think that is a reasonable suggestion. When DLL deployment was designed we
didn't think it likely (given that Dolphin Active-X DLLs are non-visual in
the Active-X control sense) that GUI support would be needed. Of course this
just goes to show that library designers can never predict how a library
will actually be used!

Blair
