Subject Re: cvs commit: jakarta-poi/src/scratchpad/src/org/apache/poi/hwpf/model/hdftypes StyleDescription.java
Date Fri, 20 Jun 2003 05:35:30 GMT
Hi all,
             After a good vacation I am back into HWPF again ....
Ryan, could you  please clear this doubt.. Will a non-complex Word file 
have PAPX's & CHPX's.

eg:- I have a Doc file with 2 paragraphs & a heading.

Heading is in caps & Times NweRoman.

Paragraph 1 has all text in lower case with Arial.

Paragraph 2 has all text in Upper case with times new Roman.

            I guess this is a non-complex  word file.

Thanks & Regards
Praveen
