Writing to the EventLog in Vista

Is it possible to write an entry in the "Windows Logs\Application" EventLog
and set the source to the name of our application, without creating a source
for our application ?
If we set source to "Application" when calling the WriteEntry method on the
EventLog class, the Source name for the entry will be "Application".

Best regards

Hi Henrik,

Actually, you're confusing the Source and Log properties of the EventLog
class, not surprisingly, as I had to look it up to ensure that I was
remembering it correctly. I wrote a number of classes to support Event
Logging a couple of years ago, and I rely on them, so it wasn't exactly
fresh.

The Log property is the log that is written to, as in Application, System,
Security, etc. The Source is the Source name that appears in the log for the
source of the log entry. Each Log can have many sources.

I'm not sure you can use an existing Source, as it may be in use already by
the original Source creator, and there may be a conflict as a result. It is
certainly possible to create your own Event Log and Event Source in Windows
Vista, as long as you have the correct (Administrator) permission to do so.

Hi Henrik,

Yes, just as MVP Kevin pointed out, you should set EventLog.Log property to
"Application" to write to "Windows Logs\Application". Then, you may use
EventLog.Source property to customize your log entry name as your
application name. Like this:

private void button1_Click(object sender, EventArgs e)
{
EventLog myNewLog = new EventLog();
myNewLog.Log = "Application";
myNewLog.Source = "MyApplicationName";
myNewLog.WriteEntry("This is a test");
myNewLog.Close();
}

Hope this helps.
