I want to raise an "event" that shows up in the system event viewer (eventvwr.exe) from .NET. Unfortunately, Google is just giving me lots of other stuff about "events" which aren't the sort of events I want to raise. What is the correct API call? Update Thanks for the answers so far.

Hi, I want to show a list of "properties" in my application. A property is simply a name/value pair. The number of properties is dynamic. The best way to do this?

I'm trying to programmaticaly determine the company* associated with a given IP address. My first guess was this : string hostname = Dns.GetHostEntry(IPAddress.Parse(ip)).HostName; but this won't work if the reverse DNS isn't set correctly, which seems to happen 90% of the time. However some websites are still able to successfully...
