Thank you for your answer!

1. yes , it is a permanently allocated string.
2. actually i used col_append_str() for appending something. At the beginning i used col_add_str(), as i getted adviced from the developer guide. I wrote "col_set_str()" by mistake in my first email. Apologise!  Thanks for the tip anyway!

windows debugger: Thanks i will check it!

FYI:
I loosed my problem actually by adding the col_append_str() routines before the " if (tree) {...}" in my dissector.
But my question remains.....why was it working in linux but in windows not???

If you feel like giving your answer here, thanks in advance!

Cheers
Manthos

1. Is " something" a permanently allocated string ??

 From the source ...
/* Use this if "str" points to something that will stay around (and thus
   needn't be copied). */
void
col_set_str(column_info *cinfo, const gint el, const gchar* str)

2. if (check_col()) is no longert needed since the check is done in
col_set_str.

See the wireshark wiki for info on using the Windows VC debugger.

Essentially: you open Wireshark exe as a "project" in the VC IDE and
then set breakpoints and etc.
