Variable for initializeData in web.config

[gslim]

I have created a trace listener and would like to give it a variable so
that when it is installed on a machine I have no control over it can
still find its logfile. Right now they are hardcoded as
"C:\Inetpub\www root\website\lo g1.txt" is there a way to insert
something like "~/logfile.txt")

<code>
<sharedListener s>
<add name="FileLogLi stener"
type="System.Di agnostics.TextW riterTraceListe ner"
initializeData= "C:\Inetpub\www root\website\lo g1.txt"/>

</code>

Another Option I could possibly do is add the tracelistener in the
application_Sta rt. However I can't seem to add it to the sourcetrace
listener only the trace. Does someone have an idea for that?

<code>
Sub Application_Sta rt(ByVal sender As Object, ByVal e As EventArgs)
' ' Code that runs on application startup
' 'Set the path to the directory for the log files, Shapefiles,
and other misc files. Basically its the application startupPath
try
dim fs as System.IO.FileS tream
dim filenamestring as String
filenamestring =
system.Configur ation.Configura tionSettings.Ap pSettings("Trac eLog")
'Todo Get this to get the path from the config file
'fs = new
System.IO.FileS tream(system.Co nfiguration.Con figurationSetti ngs.AppSettings ("TraceLog"),sy stem.IO.filemod e.OpenOrCreate, IO.FileAccess.R eadWrite,IO.Fil eShare.ReadWrit e)
fs = new
System.IO.FileS tream(server.Ma pPath(filenames tring),system.I O.filemode.Open OrCreate,IO.Fil eAccess.ReadWri te,IO.FileShare .ReadWrite)

dim sw as System.IO.Strea mWriter
sw = new System.IO.Strea mWriter(fs,syst em.Text.Encodin g.UTF8)
dim txtListener as system.Diagnost ics.TextWriterT raceListener
txtlistener = new
System.Diagnost ics.TextWriterT raceListener(sw ,"txt_Listener" )
system.Diagnost ics.Trace.Liste ners.Add(txtlis tener)
system.Diagnost ics.Trace.AutoF lush = True
dim ts as System.Diagnost ics.TraceSource
ts = new System.Diagnost ics.TraceSource ("DefaultSource 2")
ts.Listeners.Ad d(txtlistener)

catch ex as Exception
throw

my.Log.WriteExc eption(ex,Diagn ostics.TraceEve ntType.Error,"A pplication_Star t",-12)

finally

end try
End Sub

</Code>

Here is some sample code from a similar post by Steven Cheng of MS that works:

protected void Application_Sta rt(Object sender, EventArgs e)
{
FileStream fs = new
FileStream(Serv er.MapPath("~/logfiles/traceLog.txt"), FileMode.OpenOr Create,F
ileAccess.ReadW rite, FileShare.ReadW rite);
StreamWriter sw = new StreamWriter(fs ,System.Text.En coding.UTF8);

System.Diagnost ics.TextWriterT raceListener txtListener = new
System.Diagnost ics.TextWriterT raceListener(sw , "txt_listener") ;

System.Diagnost ics.Trace.Liste ners.Add(txtLis tener);

System.Diagnost ics.Trace.AutoF lush = true;
}

You could modify this to use your Server.MapPath arrangement if needed.

Yes it works (make sure the logfiles directory is already created) ,
however I'd also like my trace entries to have a timestamp so I figured I
could set the properties on the trace listener to accomplish this but THAT
that doesn't see to work .

txtListener.Tra ceOutputOptions = TraceOptions.Da teTime

but log entries don't get any time info when written. I'm certain there is
something else needs to be done but really can't imagine what it is .

Any ideas ?
thanks
