Write to eventlog from within Sharepoint webpart

Question

I'm trying to create a custom webpart. To implement error handling I would like to write to the eventlog. To do so, I'm trying to use the following code;

protected void btnExceptionTester_Click(object sender, EventArgs e)
    {
        try
        {
            throw new Exception("this is a test");
        }
        catch (Exception ex)
        {
            SPSecurity.RunWithElevatedPrivileges(delegate()
            {
                EventLog.WriteEntry("TestWebpart", ex.ToString(), EventLogEntryType.Error);
            });
        }
    }

When I try to execute this code, I receive an sharepoint error page (unhandled exception). When I look in the eventlog, I see the following message; "Requested registry access is not allowed".

I'm runnning (for testing only) under the full trust level. Can someone point out to me what kind of privileges I would need to write to the eventlog? Or is there another approach?

Help greatly appriciated!

I haven't tried writing to the Windows event log but as an alternative you can write to the SharePoint logs in the 12 hive using the following:

Microsoft.Office.Server.Diagnostics.PortalLog.LogString("your message here!");

Hope this helps
