Yeah, I didn't put a whole lot into the demo. It was more a proof of
concept than anything. To confirm the connection, you can trap the
XTYP_CONNECT message on the 'server' end (it already does that to tell DDEML
to accept the connection) in the callback, and look for XTYP_CONFIRM_CONNECT
on the 'client' callback (I think that's the correct message).

You should be able to. You'll probably have to use XTYP_EXECUTE
transactions. All the constants you'll need should be in there. I think I
got them all from the ddeml.h header file, although there are a lot of other
functions that I didn't include.

OLE is probably the preferred method (that's what the other Office app's use
to talk to each other--OLE Automation). I've looked into wrapping OLE stuff
before (mainly for drag and drop), but everything I was able to find seems
to be C++ based (which makes sense: *Object* Linking and Embedding), which
would indicate the need for an intermediary DLL to wrap the OOP stuff. I
wasn't really able to make heads or tails of the VC++ docs regarding OLE.
