Windows EventLog - populating User field

[musosdev]

Hi

I'm using the following code in a global class to add to the Windows
EventLog every time a try{} catch{} block fails...

if(!EventLog.SourceExists("darts"))
EventLog.CreateEventSource("darts", "Darts");

EventLog.WriteEntry("darts", msg, EventLogEntryType.Error);

This works great, but it doesn't populate the User field in the EventLog (it
says N/A). I'd like this to be populated with the value of
HttpContext.Current.User.Identity.Name.

Is it possible to populate this field!?

Hi muso,

Thank you for posting.

As for the .net EventLog Class's WriteEntry method, it calls the win32
"ReportEvent" API internally, also it always set "Null" to the userid
parameter for the ReportEvent API, this is why the written event entry
won't contains username info. Also, generally the userid info is not quite
used for application eventlog, it is mainly used for security log. If you
want to attach username info to the application eventlog (through .NET
api), you can consider append it to other text field like description.
Otherwise, we may need to directly use the WIN32 API to write eventlog
entry...

Hi Steven

Thanks for the reply... I'm thinking I'll find another way round this,
rather than delving into WIN32... the project doesn't warrant the time
necessary!

Cheers for the response!
