Thanks.
I did try to google the question, but the answer wasn't properly. 
I am using Windows XP sp2 which language is Chinese simp. At first, I thought the hex string was coding in cp936 or utf8, then failed. second, try to run my script on the other computer, and it run well without any error! At last, I give up.After Windows Excel reinstalled, it work, but still confused.:(
The net speed is horribly slow when connect to Pywin32 project at SF.
