Hi Barvaz,
have a look in this old post: http://www.mail-archive.com/log4net-user@logging.apache.org/msg03984.html Regards, Wolfgang From: Barvaz Barvaz [mailto:barvaz.metu...@gmail.com] Sent: Dienstag, 26.

Hi, I'd like to configure a file appender, naming the file with the current process ID (windows environment). For instance, if the current process' ID is 1234, I'd like the log file to have the name mylog1234.txt. I know it can be done programmatically (by code), but I wonder, is it achievable through configuration file? Thanks!
