Error Logging?

[HockeyFan]

I was wondering if anyone has simple code (or an example) (maybe in VB.Net)
that shows how to log a message to a file. This is to be a general logger,
that might log application errors and/or warnings. I've seen some stuff that
does this with the EventLog, but that seems a bit much for my needs. I'd
just like to be able to log to a file.
I'm figuring, to avoid collision in case another app is trying to log at the
same time, that I'll add some code to sleep a random number of miliseconds
and try the write again (allowing for up to 10 retries before considering it
to be unresolvable).

Unless someone has a better approach. Please help. It's appreciated.

HockeyFan,

The Visual Studio help topic "EventLog Class" discusses how to easily create
your own custom eventlog for a particular application and use it to log
application events like errors or warnings, etc.

RE: Error Logging?

But don't you have to "register" the application as an event source?

HockeyFan,

Yes, but that is just a call to the EventLog's CreateEventSour ce method.

Eventlogs seem like a really easy way to do application logging, but maybe
I'm missing the problem.

RE: Error Logging?

Great. I'll use it then. One question I have though, is can there be
"collisions " if multiple applications are calling WriteEntry.
