Embedding MSWord with OLE [message #441632]

Hi folks,

I am having some trouble getting this to work:

I am trying to embed a Word application with the SWT OLE classes.
Generally, I need to open Word, modify some document (or just viewing it),
close Word. At this point, when Word is closed, I need to know whether the
document was changed. If so, I open some dialog to create a change log and
other stuff.
As you can see in the code below I was trying to solve this with a Dispose
Listener on the OleClientSite. I also have tried other listeners on any
possible object, but none have worked. I always had one of those problems:

1. I opened Word in an own window (OLE.OLEIVERB_OPEN verb) and have all
the Word functionalities but I don't know how to attach the Listener in a
way that it works.
2. I opened Word in a SWT widget (OLE.OLEIVERB_UIACTIVATE or
OLE.OLEIVERB_SHOW verb) and can attach the Listener but I'm missing a lot
of Word functionalities, at least even the Word File menu. Many others are
simply disabled.

Below see the relevant code I have implemented so far. I am using SWT 3.0
and Java 1.4.2_02 on a Win2000 SP2 machine with Word 2000 SR1.

Thanks for help or even another solution,
Tobias
