Re: Bug 17208 - WordDocument Problem: createListTables - Negative Array Size

[Robert Paris <rp...@hotmail.com>]

Ryan,

Thanks for the message. I downloaded the source code to open office, but 
it's 500 megs+. I can't seem to find where in the code they actually deal 
with the MS Word Binary structure. Do you know what classes/parts of code 
deals with that? I'll definitely look through it.

Thanks.

As for the spec, I did read it and did not find anything about -1 being an 
accepted value, but all I can find is the '97 spec and nothing on 2000, so I 
didn't know if it had been changed.

For POI we should always focus on '97 formats and then if there is a 
feature we want to implement from a later version (which there are very 
few of) then we can have it disabled by default.  (maybe 
.set2000(true))...

I have no idea where to look it has been so long. If you email one of the
developers on the openoffice "Word" equivalent they may point you in the
right direction. They have always been real friendly when I needed something
like that in the past.

The spec for 2000 and XP are built off of the spec for 97. I haven't
actually seen these specs or anything but the documents created with these
products are (mostly) backward compatible with Word 97. That means that
whatever is true in the 97 spec is still true for 2000 and XP docs.
