Hi Devon,
Your question is related with Word, so maybe is better to search on
microsoft msdn library infos.
Anyway, firstly take a look on your machine for a file as VBAWDX.chm (X is
a number, I guess 9 for Word2000). If you don't have it, install it from
Word setup CD. The idea is that theoretically everything you can do it in
VBA, you can do (with some effort) also with swt.jar Oles. Is good to read
the Word help in order to understand what a Property/Method means/does.
Speaking about your code "Saved" is a Document property, not a event.
For document Events, you have to look in "dispinterface DocumentEvents"
from Word type library. As you'll see, there is no event there to catch
Document Saving.
A solution may be to catch the ApplicationEvents2.DocumentBeforeSave
(listner to be put on Application).
Regards,
Tiberiu
PS About your previous Question: Word has many problems using it as
ActiveX (in a SWT Window; my advice is to try to change your app, making a
addin in Word.

Thanks for the advice, I will take a look at the Word VB Help file.
Besides Word's unruliness as an OLE Document or ActiveX Control, I think my
major problem is figuring out how to properly hook a given interface or
event I find in the type library. I have tried to hook
ApplicationEvents2.DocumentBeforeSave with no success. Would you be able to
show me with a couple lines of code to demonstrate how this is done? I am
new to working with OLE at this level and would love an example to get me
started so that I can begin hooking into all the different IDispatch
interfaces. As my snippet demonstrates, I understand how to add the
listener on the Java end, but I think I misunderstand the process of
grabbing the correct event ID from the type library, since I never seem to
get a callback for the events I go after.
As for redesigning the app to be a Word addin, unless I am misunderstanding
you, I don't think it is an option. OLE documents are just one feature.
This app is deployed on the Rich Client Platform as a feature consisting of
about 14 plugins.
Thanks!
Devon

1. For Ole Event Code sample, take a look on available snippets on Eclipse
site
( http://dev.eclipse.org/viewcvs/index.cgi/%7Echeckout%7E/plat form-swt-home/dev.html#snippets).
Always it is good to see if is not already available a snippet, before to
put questions.
2. If you don't run a Stand alone Word, you have to create a File Menu and
to implement Save (see ActiveX help doc in Eclipse).
3. About Word Addin, I mean to consider just the communication with Word,
not your whole application.
4. Here is a sample (not very nice) just showing you that
DocumentsBeforeSave Event is catched:
Good luck,
Tiberiu
public class WordMain {
final static int DocumentBeforeSaveEvent = 0x00000008;
public static void main(String[] args) {
Display display = new Display();
Shell shell = new Shell(display);
OleFrame frame = new OleFrame(shell,SWT.NONE);
shell.setLayout(new GridLayout());
frame.setLayoutData(new GridData(GridData.FILL_HORIZONTAL |
GridData.FILL_VERTICAL));
OleControlSite site = new OleControlSite(frame,SWT.NONE,
"Word.Document");
OleAutomation doc = new OleAutomation(site);
int [] dispInfo = doc.getIDsOfNames(new String[] {"Application"});
Variant variant = doc.getProperty(dispInfo[0]);
OleAutomation app = variant.getAutomation();
variant.dispose();
OleListener listener = new OleListener() {
public void handleEvent(OleEvent event) {
System.out.println("DocumentBeforeSave Event, no. params:" +
event.arguments.length);
}
};
site.addEventListener(app,DocumentBeforeSaveEvent,listener);
site.doVerb(OLE.OLEIVERB_OPEN);
shell.open();
while(!shell.isDisposed()) {
if(!display.readAndDispatch())
display.sleep();
}
app.dispose();
}
}
