Displaying Dicom.Network logging in FormControl TextBox

[David Wetelainen]

I am able to direct FO logging to both a file and console target but am unable to direct Dicom.Network to a FormControl target. I can display regular NLog logs in the FormControl using this declaration:

Public Shared alogger As NLog.Logger = NLog.LogManager.GetCurrentClassLogger()

 alogger.Log(NLog.LogLevel.Info, "Starting application.")

With this NLog.Config:

<?xml version="1.0" encoding="utf-8" ?>

<nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"

      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      xsi:schemaLocation="http://www.nlog-project.org/schemas/NLog.xsd NLog.xsd"

      autoReload="true"

      throwExceptions="true"

      internalLogFile="c:\temp\nlog-internal.log" >

  <targets>

    <target name="file"

            xsi:type="File"

            fileName="${basedir}/Logs\log.txt"

            layout="${longdate}|${level:uppercase=true}|${logger}|${message}"/>

    <target xsi:type="FormControl"

            name="FormControl"

            layout="${longdate}|${level:uppercase=true}|${logger}|${message}"

            append= 'true'

            controlName="TxtBxLog"

            formName="frmMain" />

    <target name="console"

            xsi:type="Console"

            layout="${longdate}|${level:uppercase=true}|${logger}|${message}" /> 

    <!-- <target xsi:type="Memory" name="memory" layout="${longdate}|${level:uppercase=true}|${logger}|${message}" /> -->

  </targets>

  <rules>

    <logger name="*" minlevel="Trace" writeTo="file" />

    <logger name="FO_DicomExpress.frmMain" minlevel="Trace" writeTo="FormControl" /> 

    <logger name="*" minlevel="Trace" writeTo="console" />

  </rules>

</nlog>

Here is a sample console log that I would like to display in a textbox.

Hi David,

I am no expert in the FormControl target, but shouldn't the name attribute in the FormControl logger be set to for example * or Dicom.Network (if you want to delimit your output to networking? I.e. like this:

    <logger name="*" minlevel="Trace" writeTo="FormControl" /> 

Regards,

Anders @ Cureos

Hi Anders,

So while I was making changes to NLog.config from within Visual Studio, I forgot the important step of copying the modified config file to bin\debug or bin\release folder to be read when running the application. 

Once I remembered to copy the file and following your suggestion, this now works!

<logger name="*" minlevel="Trace" writeTo="formcontrol" /> 

Thank you for your reply
