Write specific error to a text file?

Write specific error to a text file?

  Try adding the following into your catch block.  You'll need to replace emailAddr with the actual email address and update the path to the log file that you want to use. Also make sure that you import System.IO

      Using sw As StreamWriter = New StreamWriter(File.Open("MyLogFile", FileMode.Append))
        sw.WriteLine("Email to {0} failed at {1}: ", emailAddr, DateTime.Now, ex.Message)
      End Using

  Hi Tory;

  Just configure a trace listener in you application configuration file. Trace listeners can be configured through your application configuration file and turned on or off. even more, you can have trace listners that write to log file or event log.

  Your configuration file should look like..

  <configuration>
   <system.diagnostics>
    <trace autoflush="false" indentsize="4">
     <listeners>
      <add name="myListener" type="System.Diagnostics.TextWriterTraceListener" initializeData="mylog.log" />
      <remove name="Default" />
     </listeners>
    </trace>
   </system.diagnostics>
  </configuration>

  Then your code should look something like...

  If _mailCounter.Text < MaxMessages Then 'DONT OVERLOAD MAIL SERVER

  Try

  System.Web.Mail.SmtpMail.Send(MM)

  Catch ex As Exception

  System.Diagonistics.Trace.WriteLine("Error Sending Message. error was: " + ex.Message) ' do not concatenate strings, use string builder instead

  Err.Clear()

  End Try

  End If

  Or Simply use the my classe to append the message to the text file

  My.Computer.FileSystem.WriteAlltext("MyLogFile", "Email to " & emailAddr & " failed at : " & DateTime.Now & ":" & ex.Message, True)
