.NET Forum / ASP.NET / General / February 2008Logging Application Block Not Writing to Vista Event Log
Running Vista x64. Visual Studio 2008 Web Application Project. I installed Enterprise Library 3.1, built it, and modified the web.config. I want to log everything to a text file, and log everything that is a Warning or more severe to the Application Event Log. Everything properly logs to the file, but nothing is in the Event Log. Why? My C# Code: LogEntry logEntry = new LogEntry(); logEntry.EventId = 100; logEntry.Categories.Add( "TestCategory" ); logEntry.Priority = 1; logEntry.Severity = TraceEventType.Error; logEntry.Message = "qwerty"; logEntry.Title = "asdfgh"; logEntry.MachineName = Environment.MachineName; Logger.Write( logEntry ); In my web.config: <loggingConfiguration name="Logging Application Block" tracingEnabled="true" defaultCategory="" logWarningsWhenNoCategoriesMatch="true"> <listeners> <add fileName="c:\trace.log" header="----------------------------------------" footer="----------------------------------------" formatter="Text Formatter" listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.FlatFileTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" traceOutputOptions="None" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.FlatFileTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" name="FlatFile TraceListener" /> <add source="Source00001" formatter="Text Formatter" log="Application" machineName="" listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.FormattedEventLogTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" traceOutputOptions="None" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.FormattedEventLogTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" name="Formatted EventLog TraceListener" /> </listeners> <formatters> <add template="Timestamp: {timestamp}

Since you're developing an ASP.NET web applicaiton, are you using the VS IDE's built-in test server or host the application in IIS? I suggest you try the following things first: ** change the listenter setting and also let EventLogListener to log all the messages(not only high severity ones) ** in your ASP.NET application, use normal .NET EventLog API to log into the same EventSource to see whether it works.

Therefore, you can try checking whether you can get this code work or if your original problem is due to the eventsource is not correctly created.

[quoted text clipped - 139 lines] >>></specialSources> >>></loggingConfiguration> That does not show me how to do it with the Logging Application Block. I know how to manually log with code. I need to see a simple web application project's web.config file and .cs file showing how to write errors-only to the application event log while writing all information (debug/trace/error) to a local text file. Please try again. Thanks. >Thanks for your reply Coconet, > [quoted text clipped - 16 lines] >} >=================== Thanks for your reply, The Enterprise Library Logging block code is also straightforward, my test just used a single EventLog Listener and write a message into the test event source. On Vista box, it execute under an application run with Elevated privilege and it works well. ======code======= private void button1_Click(object sender, EventArgs e) { LogEntry entry = new LogEntry(); entry.EventId = 1; entry.Priority = 1; entry.Message = "This is a test message."; entry.Categories.Clear(); entry.Categories.Add("General"); Logger.Write(entry); MessageBox.Show("Log is written"); } ===================== =========config ========== <?xml version="1.0" encoding="utf-8"?> <configuration> <configSections> <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSet tings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> <section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSetti ngs, Microsoft.Practices.EnterpriseLibrary.Data, Version=3.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> </configSections> <loggingConfiguration name="Logging Application Block" tracingEnabled="true" defaultCategory="General" logWarningsWhenNoCategoriesMatch="true"> <listeners> <add source="Enterprise Library Logging" formatter="Text Formatter" log="Application" machineName="" listenerDataType="Microsoft.Practices.EnterpriseLibrary.Logging.Configuratio n.FormattedEventLogTraceListenerData, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" traceOutputOptions="None" type="Microsoft.Practices.EnterpriseLibrary.Logging.TraceListeners.Formatted EventLogTraceListener, Microsoft.Practices.EnterpriseLibrary.Logging, Version=3.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" name="Formatted EventLog TraceListener" /> </listeners> <formatters> <add template="Timestamp: {timestamp}
