I have an application using NLog for logging. My configuration is stored in NLog.config file, but I need to provide option to change it for the user. I know how to change Logger configuration, but is it possible to save such changed configuration back to NLog.config file programmatically so it stays changed also after application stopped?
Thanks a lot!

I had more or else similar issue. I needed to edit the nlog config file. since i was using net2.0 , I was not able to use linq to edit the nlog config file . but edited the file using xdocument.
hope the link below helps.

You can follow the following link which gives a details about Configuration API which may help you.

I am trying to configure wso2 by modifing its configuration file named "carbon.xml", but no matter what change I do to "carbon.xml", even adding a single "white space" or modifying a comment it's enough for the wso2 server to reset carbon.xml file to it´s original "out of the box" state.
I tryied to protect the file carbon.xml by dropping write permissions, but in this case wso2 server refuses to start, it aborts execution and displays an error complaining that it was not able to "write new configuration" !!!
Does any one know how to solve this?
I found the answer, In wso2 version 5.9 there is a new centralized configuration file, named "deployment.toml". Configurations must be done in this file and then wso2 propagates changes to the respective configurations files, like carbon.xml or catalina-server.xml, for example.
If you delete "deployment.toml" wso2 will fallback to previos behavior.
With the new 4.5.0 carbon-kernel release, all WSO2 products such as APIM 3.0.0, IS 5.9.0 introduced a new config model. According to the new config model, there is a centralized configuration file (deployment.toml) where users add the configurations, then those configurations will be added to the respective .xml files.
This new config model was introduced in order to simplify the configuration (previously there were a lot of configuration files) and to increase the user experience. Please follow this documentation to refer further information on this new config model

If you have a deployment.toml file, the changes directly made into the xml files will be overiden during the server startup. Deleting the deployment.toml file will use the old config model. But it is not a recommended approach.
I have created a .erl file named "confirmDelivery.erl" and compile it successfully, A beam file named "confirmDelivery.beam" has been created.
All these files are in /etc/ejabberd/. Now I wanna add the functionality of this file into ejabberd, But I don't know how to link my file with ejabberd server.
Please help me, I will be really really thankful to you.
You need to place your beam files in the path of the Erlang VM to be able to use them. You should have a look at where are other ejabberd module for example and place it in the same directory.
You need to put your beam file in etc/ejjaberd/ebin folder and call it from ejabberd debug mode.
use command:
ejabberdctl debug
I am trying to adopt Log4j2 to my project. Since my Java Application is packeted in a JAR file. I don't want "log4j2.xml" configuration packaged inside of JAR file. I am trying to learn how configuration file works from "http://logging.apache.org/log4j/2.x/manual/configuration.html"
But seems there is no clear instruction regarding altering the configuration file path of the Log4j2.
After googling about this topic I found something like "Referencing log4j config file within executable JAR" Referencing log4j config file within executable JAR, But this solution is not available any more according to "http://logging.apache.org/log4j/2.x/manual/migration.html" (if I understand it correctly).
So I am wondering if someone have any idea about this issue.
Thanks
You can set the system property to specify the configuration path.
set the
"-Dlog4j.configurationFile="D:\learning\blog\20130115\config\LogConfig.xml"
in VM arguments. replace
"D:\learning\blog\20130115\config\LogConfig.xml"
to your configuration path.
Put the log4j2.xml file in resource directory in your project so that the log4j will locate files under class path automatically.
Loading log4j2.xml file from the customized location-
You can use the System property/ VM arguments- Dlog4j.configurationFile=file:/path/to/file/log4j2.xml
This will work for any web application.
For some legacy applications, you can create a class for loading log4j2.xml/ log4j2.properties from the custom location on the machine like- D:/property/log4j2.xml
Using any of these approach,during application startup, the log4j2.xml file from the src/resources folder will be overridden by the custom location log4j.xml file.
Try using -Dlogging.config=Path_to_your_file
i want to use my mysql databases in weka in order to analysis data.
i download the mysql-connector-java-5.0.8-bin.jar and put that in weka folder in my program Files folder, and add this path to system variable path, but when i open the weka explorer and click the openDB, i don't know what should i write in the url textbox,
i don't know completely what should i do?
the error that i saw is:
problem connecting to database:
no suitable driver found for!
please give me a total guidance, thanks in advance.
add mysql-connector-java-5.1.12-bin.jar to CLASSPATH .
or put it in weka folder, navigate to weka installation folder and run command :
%java_home%/bin/java -Xmx300M -cp ".;weka.jar;mysql-connector-java-5.1.12-bin.jar;" weka.gui.GUIChooser
then click open DB and
fill in the proper user+password
put the url: jdbc:mysql://localhost:3306/DATABASENAME
Click Execute. The result window should show the results now.
For Weka 3.7.10, the classpath system environment variable is not took into account (at leat under Windows 7). The only working approach for me was to modify the RunWeka.ini file from the Weka installation folder as follows: the cp= setting was modified to:
cp=%CLASSPATH%;d:/Programs/jdbc/mysql-connector-java-5.1.26/mysql-connector-java-5.1.26-bin.jar
whereas only the %CLASSPATH%; setting was originally provided. Does not make much sense, but in worked.
find some introduction to WEKA and the environment variable:
http://weka.wikispaces.com/CLASSPATH
Copy mysql-connector-java-X.X.XX-bin.jar to /usr/share/java/
unizip /usr/share/java/weka.jar
edit: /usr/share/java/weka/experiment/DatabaseUtils.props
add:
jdbcDriver=com.mysql.jdbc.Driver
jdbcURL=jdbc:mysql://localhost:3306/test (with your server)
add shell
export CLASSPATH=/usr/share/java/mysql-connector-java-X.X.XX-bin.jar:
export CP=/usr/share/java/mysql-connector-java-X.X.XX-bin.jar::/usr/share/java/:/usr/shared/java/weka.jar
execute weka:
java -cp $CP -Xmx500m weka.gui.explorer.Explorer
Ready
I am trying to read and write into app.config file of user-settings. I found a snippet of a code for working with confige file. I finally got it compiling and running, but it absolutely seems to be doing nothing to the App.config file.
Here is the code:
Method MainForm1.Button1.Click(sender: System.Object; e: System.EventArgs);
var
config : System.Configuration.Configuration;
begin
config:=ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
config.AppSettings.Settings.Add('PreferenceToRemember','value1');
config.Save(ConfigurationSaveMode.Modified);
ConfigurationManager.RefreshSection('appSettings');
end;
It is compiling without any errors, but I don't know if it is doing anything.
Is there anything wrong with the code? I need to be able to write/read a section and write/read a key/value. Thanks in advance.
UPDATE: Instead of using ConfigurationManager, I simply use Properties.Settings.Default. However, I am having bit of a problem writing into it and reading back from it, although program complies with without any errors and the code seems simple.
How do you read and write to Properties.Settings.Default from within your code?
Maybe you're looking at the wrong file?
The app.config you have in your solution will be copied to YourProgramFile.exe.config in the bin/Debug or bin/Release folder. When running your program it will update this file, not the app.config file in your solution.
Then perhaps you also should check write permissions on your application folder. Normally (Win Vista, Win 7) the User executing an application does not have write permissions in the Program Files folder where your application should reside, so updating the .config will most probably fail due to the lack of write permissions. This is even more true for Linux/Unix systems.
You should try to separate the elements you need to write and write an additional config file in a user-specific folder. You can take the defaults from the normal application config for that initially and just update the user-specific config file, this way you are not hindered by file permissions and every user can update their settings specifically.
