I am looking at SWT to replace an older choice to embed Word, Excel docs in the Java application.

But I cannot figure out if possible to use org.eclipse.swt.ole.win32.OleAutomation without displaying the Word for instance.

Can someone give me an answer as I cannot figure out if swt was also created for use cases where the presentation of the document is not necessary.

Next are only details of the use case.
The part where users are offered to edit a Word document inside the Java fat client works as with the older solution from Infozoom.

But I would also like to use OleAutomation for instance to apply SaveAs (i.e. to PDF) on a docx file that the user created before but is not looking at it at the moment.

But I get an error on SWT_AWT.new_Shell(display, canvas);

In fact the the instantiating is like this:
OleAutomation automation = new OleAutomation( site );
but the instantiating of the Site being
site = new org.eclipse.swt.ole.win32.OleClientSite(
oleFrame, org.eclipse.swt.SWT.NONE,

requires an oleFrame.

thank you, Alex

This is a really detailed technical question and I doubt many people have much experience with using SWT's OLE integration. I assume you got things working also by looking at the SWT snippets:

I used this stuff recently at a customer engagement mostly looking to improve performance. I was able to use it to automatically convert an older Excel format to a newer one...

You might get better help in the SWT forum:
