Hi Anthony,
Thx for your example,
word files my application has to modify are scientifics abstracts synopsis
which could contain graphics and tables. The fact is i 've to insert some
aditionnal information like names, abstract's title, etc. My code is ok when
content is only text but updates fail when word file holds graphics, images
or tables. The most incredible is that MS Word CAN'T open it but OpenOffice
should open it with damage content.
So, i'm lost !!! Hope it has solution... I'm thinking in creating an
abstract template with form at the beginning or the document. Hope, filling
fields form could maintain structure and so on avoid fail / bad alteration
of file content.
If any one has tested it... Share information please !
