Thanks!  There is still a problem I can not fix..

when I try to use col_append_fstr() to add a string from the packet to 
COL_INFO. That string is at the end of a record(packet) without a "NULL" 
ended, but we know length of the string. The problem is it seems  that 
the tvb_memdup(tvb,offset,length) is not working very well, it show more 
bytes (which cross the packet) on the COL_INFO.

do you have a good solution to it?

Thanks,
huagang
