Bug in POIFS documentation ?
Hi,
I was reading through POIFS documentation given in
site and trying to correlate with an xls file opened
in a Hex editor. I noticed the following. Please
clarify whether this is an error in POIFS
documentation.
1) Header
Doc says
FileType, Uk1, Uk2, Uk3, Uk4, Uk5, Uk6,
LOG_2_BIG_BLOCK_SIZE
According to doc Uk4 should be 0x003B (default).
I noticed that there is another unknown integer
constant between Uk3 and Uk4 (say Uk3a). Only after
this Uk4 comes. So is the doc wrong ?
2) Property -
The final param SIZE is at offset 0x78 and is of type
Integer (size = 4 ). So property will end in 0x82. But
size of property is 128 (0x80). So what is wrong?, Is
SIZE is of type short or some offset in between has
gone wrong.
(I do not think size is short. It should be "int",
else how can it hold big values. So I think offsets in
between has gone wrong ?)
Can any body please clarify ?
Thanks
Obi Van

Hi ,
Sorry to flood your mail boxes. ****The documentation
is perfect*****. Even first question is not valid. I
did not see the offset. (The offset is not in
arithmetic progression, that is why I thought the
constants were sequential.)
Thanks

Hi,
oops
I am Sorry. I take back the *second* question
0x78 + 4 = 0x7C (not 0x82)
But *first* question is still valid.
Thanks
