Hi All, I'm still at a total loss as to how to get log4net successfully writing to a custom event log, writing to the Application event log is working exactly as expected. I have started using the IEventIDLog extension in order to pass over event IDs to the log messages to see if this makes any difference. I've looked over google a lot over the last couple of days and have tried everything I have found in terms of suggestions. The most recent one being this: http://www.mail-archive.com/log4net-user@logging.apache.org/msg02396.htm l Which talks of the same error I'm seeing in the application log that I mentioned before:
I try to write to MyLog and this is entered into the Application log: The description for Event ID ( 0 ) in Source ( MyFirstApp ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: 2009-06-19 12:11:27,234 14 INFO <MachineName> <username> Logging.TestHarness.vshost.exe (line: 220) Logging.TestHarness.LogEntryCreator - Message number 71 System.Exception I think tried this suggestion: ILog logger = LogManager.GetLogger(sender); log4net.ThreadContext.Properties["EventID"] = 12; logger.Info(0,message); Which didn't make any difference. I have checked over the Sources key entries being created in the registery and all seems to be correct in there as well. I just never see *anything* making it into the MyLog event log. I've probably got another 2 hours left to use on this before I have to move onto other work which is incredibly frustrating as I will leave behind a 'buggy' half finished wrapper. Any input would be much appreciated. :| James
