Application Log Writing

Hi,

I'm trying to write to the application event log. This code will be executing on an unattended server so this is the best place to write it. I keep receiving a "Security" error trying to read the security log to see if my logname exists. I'm missing something, but I can't seem to figure out what. I've tried with and without the appLog.Log = "Application";

Here's my code....

Thank you,
Glenn

C#

status = string.Format("{0} - {1}, {2},\n CreateDB (Create 'Server' table) 
                       returned:  {3}, \n{4}",
                        DateTime.Now,
                        System.AppDomain.CurrentDomain.FriendlyName,
                        System.Environment.MachineName,
                        ex1.Message,
                        ex1.StackTrace);

System.Diagnostics.EventLog appLog = new System.Diagnostics.EventLog();
appLog.Source = CommonClass.Product;
appLog.Log = "Application";
appLog.WriteEntry(status);
return (status);

This is not how it works. It's not quite clear what you are trying to achieve, but probably you are trying to log in the application-specific directory. Here I explain how to achieve that: How to create event log under a folder[^].

Hi,

I've tried your method of creating an application log, however i'm still getting the same exception: "The source was not found, but some or all event logs could not be searched. To create the source, you need permission to read all event logs to make sure that the new source name is unique. Inaccessible logs: Security."

The exception is occurring on the CreateEventSource within the Install method:
EventLog.CreateEventSource(ApplicationName, EventLogName);

ApplicationName = "Cert", EventLogName="CommonServices"

I'm running Windows 8.1, not sure if that makes a difference or not.

Thanks,
Glenn

I tested my method before posting, it surely work, but I did not try Windows 8 (it would be strange if it is not backward-compatible in this respect). You probably did not reproduce the full cycle of it, say, failed to install the event source due to insufficient permission... What if you try to run installation part as administrator (with elevated permission)?
