Question on Complex File Testing
Can anyone tell me how I can create a complex Word file (i.e. fast-saved)
for testing? I can't figure out how it gets created.
Thanks!

You mean it's non-standard? :8O <-- Big look of shock! I don't believe it!
LOL.
Thanks! I'll give that a try.

RE: Trying to understand PAPX Code
Posted by Robert Paris <rp...@hotmail.com>.
Hey I think I found the problem, and it wasn't what I mentioned before.
in PAPFormattedDiskPage, right after the code to get the size of the
PAPX/GRPPRL, the code creates a new papx byte array and then populates it
starting with THE NEXT BYTE! That's wrong! The next byte should be the istd.
so the code:
[WRONG-CODE]
if(size == 0)
{
size = 2 * LittleEndian.getUnsignedByte(_fkp, _offset +
++papxOffset);
}
else
{
size--;
}
byte[] papx = new byte[size];
System.arraycopy(_fkp, _offset + ++papxOffset, papx, 0, size);
[/WRONG-CODE]
Should read:
[CORRECT-CODE]
if(size == 0)
{
size = 2 * LittleEndian.getUnsignedByte(_fkp, _offset +
++papxOffset);
}
else
{
size--;
}
//HERE'S THE CHANGE
byte istd = _fkp[ ++papxOffset ]; //THIS MOVES IT FORWARD PAST THE
istd BYTE
byte[] papx = new byte[size];
System.arraycopy(_fkp, _offset + ++papxOffset, papx, 0, size);
[/CORRECT-CODE]
This fixes my problem where I was getting SprmType's of 0. They're now all
valid. I hope this helps!

Trying to understand PAPX Code
Posted by Robert Paris <rp...@hotmail.com>.
Can someone explain this to me?
In the code for getting the PAPX (getGrpprl of PAPFormattedDiskPage), the
following code is used to determine the size of the PAPX:
[CODE]
int papxOffset = 2 * LittleEndian.getUnsignedByte(_fkp, _offset +
(((_crun + 1) * FC_SIZE) +
(index * BX_SIZE)));
int size = 2 * LittleEndian.getUnsignedByte(_fkp, _offset +
papxOffset);
..other code elided ..
[/CODE]
What I don't understand is the papxOffset code and the size code. As I
understand the documentation, the first byte of the PAPX (since we're in an
FKP here) holds the count of words for this PAPX. So why isn't the
papxOffset simply:
int papxOffset = _offset + ( ( ( _crun + 1 ) * FC_SIZE ) + ( index *
BX_SIZE ) ) ) + 1;
I don't understand why you're getting the last byte of the BX's and then
multiplying that value by 2. I don't see where in the documentation it says
that the byte at that spot is something that indicates our offset for the
PAPX's. (I may be missing something)
I ask because in using the above code, I keep getting weird values, such as
my sprm types keep coming up as 0, which of course is not a valid type. Can
someone explain the above code to me?
Thank you very much for any help you guys can give!
Robert

How figure out footnote mark? (If not auto-generated)
Posted by Robert Paris <rp...@hotmail.com>.
I've been able to properly grab all footnotes and place them properly in the
text. Also, when auto-generated, I'm able to get the number for the
footnote. However, when the footnote uses a custom-mark, I can't figure out
where to get the info on the length of the mark (since it's simply included
in front of the text for that footnote in the footnote text located at fcMin
+ ccpText).
Does anyone know how to figure out what a footnote's custom mark is?
Thanks!

RE: Question on Complex File Testing

Hi Robert,
Make sure that "fast-save" is turned on Microsoft Word. Then, keep making
adjustments to a document, and resaving. Word sometimes decides to save in
"fast-save" mode when it feels like it.

Kais Dukes
