In previous article " Implement Nlog in .Net core MVC application part 1 "  I have demonstrated how we can implement basic setup of NLog in .core mvc application. In previous article we have logged the exceptions in flat file system. In this article I will show you how you can write the exception and custom logs in csv file. Writing logs in csv file can enable us better readability of logs in tabular form.       Lets start the implementation of it, I going to use the same example project used in previous demonstration. Modify the Nlog.config file as follows, added new target and rule for logging logs in csv file. <?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="fal

Logging is a very important part of the enterprise application/web application. Setting up the logging correctly not only beneficial for long term maintenance of the application but also it is useful tool to find out the RCA in case of mission critical bug arises. Therefor we will going to discuss the various logging technique implementation using Nlog library package. In this article we will going to use .net core application for demonstration but you can implement it in .net framework application also. So lets start the implementation of Nlog in .net core MVC application. Open visual studio 2019/17 and create the new project as shown below.     Select Asp.net core Web App (Model-View-Controller) and provide the project name in project name text box.   Now on next screen click on create button this will create MVC app with .net core Now go to solution explorer and right click on project and click on Manage Nuget Package. Now in Nuget package manager install below listed Nlog packages.

Disable backspace key in HTML form using Jquery in simple steps. While user enters data into application if user accidentally  press backspace button then it will redirect to previous page and all entered data would be lost. to eliminate this event we can disable the backspace key using Jquery. Following is the JQuery script tag you can add to the web page $(document).keydown(function (e) { var nodeName = e.target.nodeName.toLowerCase(); if (e.which === 8) { if ((nodeName === 'input' && e.target.type === 'text') || nodeName === 'textarea') { // do nothing } else { e.preventDefault(); } } }); The above code can be used seamlessly with any web technology you are using. Hope this will help you in your web application. Happy coding:)

In practical situation you need to clone of object so that change in cloned object will not affect the original one. If you need a cloned list with the same capacity you need to do some extra stuff with your user type. I came up with this easy solution using ICloneable interface in your custom type class. The first step you need to implement the ICloneable interface in your class like below. public class MyClassDto : ICloneable { public Int64 Id { get; set; } public string Time { get; set; } public int user{ get; set; } public object Clone() { return new MyClassDto{ Date = this.Date, Id = this.Id, user = this.user}; } } after that you need to add extension method in common class so that you can use it everywhere you want. public static class Extensions { public static List<T> Clone<T>(this List<T> listToClone) where T : ICloneable { return listToClone.Select(item

To validate user input for email-id it's very easy using regular expressions. Using regular expressions you do not need to write lengthy logical code in jQuery. Following are the steps to do the same. Pass a string to RegExp or create a regex using the  // syntax Call  regex.test(string) So code would be... jQuery ( function () { $ ( ".mail" ). keyup ( function () { var VAL = this . value ; var email = new RegExp ( '^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$' ); if ( email . test ( VAL )) { alert ( 'Great, you entered an valid E-Mail-address' ); } }); });
