Date Tue, 04 Jul 2006 14:06:14 GMT
Hi

Attach the bad ppt and we will see what is wrong.
Also I would like to see the code which saves ppt images.

mj> Hi

mj> I'd like to report an error that i found while using POI. I was retrieving
mj> the pictures from a ppt file and saving each one in a file and it was
mj> working ok, but i deleted one of the pictures of the PowerPoint file and POI
mj> was still saving it in a file. Then I realized that it happens when the

mj> Any suggestions?

mj> Thanks,
mj> mr_jonze.
