Hi Song,

if you can make the office play dead, yes that is a bug.
Obviously the
document is recursivle loading itself until your heap is
full and then
will crash.
So what kind of help do you need? Do you want to know how to
file an
issue for that or do you want to
know how to fix that issue? Or something else?

Regards,
Christian

hi Christian,

Thanks for you help. I want to know how to fix the issue. 

I did check the code, and didn't know how to modify the
code.

I made more test in Impress and in MS Office PowerPoint
2007, MS Office have another solution to the problem.

TEST 1:
I made the file linked to itself, the approach is same to my
former letter.
TEST 1 result:
In Impress : the operation is success, but the Impress do
not open the saved file forever.
In MS Office: MS Office PowerPoint will pop a dialog with
"PowerPoint do not insert itself".

TEST 2:
I made two files, the first file linked to the second file,
and the second file linked to the first file.
TEST 2 result:
In Impress : the result is same to the TEST 1.
In MS Office: the operation is success. but, it will pop a
dialog when open the file next time, and have a small
problem.

Regards

To know how to fix the issue, you need to debug the issue
and come up
with a solution.

No problem at all, just remember to give as much information
as
possible, this helps a lot understanding what you try to
comunicate.

MS Office PowerPoint will pop a dialog say "Microsoft
Office already confirmed a potential safety problem". I
closed the dialog, the view can't display the OLE object
normally. when I click the view, the process pop that dialog
again.

You already described it very well. So it looks like MS
Office does some
kind of safety checks, including to look for circular
references in
documents. This would also
be a nice feature to have. This could be done at load time
by gathering
a list of 'parent' documents and when inspecting child
documents, verify
if they are not already
in that list. The xml filter usually take an XPropertySet
where such
information can be supplied to the filter. See sdxmlwrp.cxx
in sd
project as an example how the
XPropertySet is given to the filter.

Adding a dialog and preventing the user to insert the
actuall document
as an ole object would be a good fix for the first issue.
Fixing that two documents reference each other is a little
bit more
advanced and should be fixed for all applications. So you
should at least submitt three issues describing the problem,
one for
calc, impress and writer. Maybe we can even fix this
in the framework project so the solution for each
application uses the
same base implementation.

Christian
