Specifying a log for a Service

[TT (Tom Tempelaere)]

Hi people

I am trying to set the log for my service in the installer class (System.Configuration.Install.Installer). I override Install and Uninstall. The install method looks like this

public override void Install(IDictionary stateSaver

if( !EventLog.SourceExists(MyServiceName)
EventLog.CreateEventSource(MyServiceName, MyLogName)
base.Install(stateSaver)
The MyServiceName is the same as the name of my service

The installer complains "Source MyServiceName already exists on the local computer". But (1) I am explicitely checking whether the source exists before creating the source(!!!), and (2) my log has a completely different name (MyLogName) than the existing logs (Application...), and (3) creating an Event source requires both the source name and the log name. This doesn't seem very logical. The error message

<error_message
[...
Installing service MyServiceName..
Service MyServiceName has been successfully installed
Creating EventLog source MyServiceName in log Application..

An exception occurred during the Install phase
System.ArgumentException: Source MyServiceName already exists on the local computer
[...
</error_message

At line 3 you can see that the installer is creating the source behind my back; for log Application. Then the exception occurs. I seem to be creating a source that already exists, BUT in my code I explicitely CHECK whether the source already EXISTS before creating it. Plus I register the source for ANOTHER log than Application (MyLogName)

Pffff. If I get grey hair before I'm thirty, I'll definitely know why ... Does anyone have any idea

Thank you
Tom
