How to: Write Log Messages (Visual Basic) Visual Studio 2015 Other Versions Visual Studio 2013 Visual Studio 2012 Visual Studio 2010 Visual Studio 2008 Visual Studio 2005 You can use the My.Application.Log and My.Log objects to log information about your application. This example shows how to use the My.Application.Log.WriteEntry method to log tracing information. For logging exception information, use the My.Application.Log.WriteException method; see How to: Log Exceptions in Visual Basic. ExampleThis example uses the My.Application.Log.WriteEntry method to write out the trace information. VB Copy Public Sub TracingTest(ByVal fileName As String) My.Application.Log.WriteEntry( "Entering TracingTest with argument " & fileName & ".") ' Code to trace goes here. My.Application.Log.WriteEntry( "Exiting TracingTest with argument " & fileName & ".") End Sub .NET Framework SecurityMake sure the data you write to the log does not include sensitive information such as user passwords.

What i'd like to have happen, if there is an exception is have it log that exception to a text file. I have: Catch ex As Exception MsgBox(ex.Message) My.Application.Log.WriteException(ex, TraceEventType.Error, "Exception " & "with argument " & "C:\Log.txt" & ".") End Try But it's not sending the exception to the logfile. http://stackoverflow.com/questions/24017860/how-to-log-catch-exception-to-a-text-file What am I missing? vb.net try-catch share|improve this question asked Jun 3 '14 at 14:30 Shmewnix 44371739 1 While not an answer to your question, you should look into Elmah for error logging. asp.net/web-forms/tutorials/deployment/… –MiniRagnarok Jun 3 '14 at 14:32 i wouldn't know. i wrote my own logging class. also, you could be missing this: msdn.microsoft.com/en-us/library/yhx0xwks.aspx –porkchop Jun 3 '14 at 14:34 you probably do not have access to write to "C:\" change to a temp folder or a Users folder –Plutonix Jun 3 '14 at 16:04 add a comment| 1 Answer 1 active oldest votes up vote 1 down vote I think the example here: http://msdn.microsoft.com/en-us/library/dsxzceby(v=vs.90).aspx might have mislead you a bit. I find it a bit odd. I think this is probably better: Public Sub SomeMethodWhichMightGenerateException(byval someArg as String) Try ' Code that might generate an exception goes here. ' For example: ' Dim x As Object ' MsgBox(x.ToString) Catch ex As Exception My.Application.Log.WriteException(ex, _ TraceEventType.Error, _ "Exception with argument " & someArg & ".") End Try End Sub fileName is just a random variable in the msdn example and nothing to to do with where the Exception is logged... Look here htt

Independent reviews of Visual Basic programming and technical books Independent reviews of Visual Basic programming and technical books Programming Visual Basic Quick Tips for Programmers Programming Office The .NET Framework - Tools and Techniques Threading and Multiprocessing in Visual Basic .NET Erik Von Weber/Stone/Getty Images Logging, as described in this article, is the way a program can record exceptions for problem resolution. Logging is often combined with the related functions Tracing, Debugging, and Instrumenting and the techniques used really are similar. But the focus in this article is to write code that records an exception event.This is more important than you might think because the technical documentation at Microsoft really relates more to Tracing, Debugging, and Instrumenting than just logging exceptions and they don't make the distinction clear. The inspiration for this article was a request for help from someone who had gone down the wrong track and wasted a lot of time.Logging in VB.NET is both easy ... and a little more complex at the same time. It's easy if you just want to use the My.Application.Log object. If you're writing ASP.NET, use the My.Log object instead. continue reading below our video How Does 3D Printing Work? In the last segment of the Visual Basic .NET 2010 Express tutorial, Errors: Preventing and Handling Them, logging is used to handle an error in an XML file using My.Application.Log. Try Catch e As XmlException My.Application.Log.WriteException(e, TraceEventType.Error, "Exception in ExceptionLogTest.") End Try If you need to log any exception, not just one trapped with a Try-Catch block, you can add some co
