Ocassionally I'll see a Nevron message in the VS output window when debugging.  For example, here's one I get when I try to load a 2012 file using Nevron 2011: Failed to load from file. Exception was: The element or one of its descendants has an invalid unique id.

My question is, do these types of messages get saved to a log file anywhere? Or is there some utility that our customer could run that would intercept these messages? Thanks,

Could one of the engineers take a quick look and tell me what technique is used to perform logging?  Is it just Console.WriteLine or something more sophisticated?

Specifically, what I'm trying to find out is that we have some customers who can't load an .nlx file during initialization of our product.  I'd like to find out if there is some way to see what Nevron is logging as to the reason.  Very similary to the example shown in my original post, no execption is thrown, so I'm hoping there is something logged that I can look at.

Thanks.

Hi,

Generally the diagram traces all caught exceptions with the standard for .NET Trace.WriteLine method. You can easily intercept the trace like that:

....
    Trace.Listeners.Add(new MyTraceListener());
....

public class MyTraceListener : TraceListener
{
    public override void Write(object o)
    {
        base.Write(o);
    }

    public override void WriteLine(string message)
    {
        Console.WriteLine("WriteLine: " + message);
    }

    public override void Write(string message)
    {
        Console.WriteLine("Write: " + message);
    }
}

Thanks. In case anyone else is interested, I found DebugView from SysInternals, which captured a Nevron Trace message in my initial test:
