    use below code firefrox

    function NumberOnly(evt)
    {


    var AsciiValue = (evt.which) ? evt.which : event.keyCode
    // alert(AsciiValue);
    //var AsciiValue=event.charCode ? event.charCode : event.keyCode;

    if((AsciiValue>=48 && AsciiValue<=57) || (AsciiValue==8 || AsciiValue==127))
    AsciiValue.returnValue=true;
    else
    {
    alert("Enter NumericValues Only"+AsciiValue);
    AsciiValue.returnValue=false;
    }
    }

    Use Below code to worked in Firefox,Chrome & IE

    Javascript Function :
    function NumberOnly(evt)
    {
    var AsciiValue = (evt.which) ? evt.which : event.keyCode
    // evt.which fires in Firefox & event.keyCode works in chrome & IE
    if((AsciiValue>=48 && AsciiValue<=57) || (AsciiValue==8 || AsciiValue==127))
    {
    evt.returnValue=true;
    }
    else
    {
    alert("Enter NumericValues Only");
    evt.returnValue=false;
    }
    }

    Execution Step :
    on Input Control add the Event as onkeypress='functionname(event)'
    Event means – Which Event Fires

C# HttpClient tutorial C# HttpClient tutorial shows how to create HTTP requests with HttpClient in C#. In the examples, we create simple GET and POST requests. The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web. HttpClient  is a base class for sending HTTP requests and receiving HTTP responses from a resource identified by a URI. C# HttpClient status code HTTP response status codes indicate whether a specific HTTP request has been successfully completed. Responses are grouped in five classes: Informational responses (100–199) Successful responses (200–299) Redirects (300–399) Client errors (400–499) Server errors (500–599) Program.cs using System; using System.Net.Http; using System.Threading.Tasks; namespace HttpClientStatus { class Program { static async Task Main(string[] args) { using var client = new

SonarQube Configuration For .NET Core Web API

When multiple developers are working on the same project, it's good to have a code review. SonarQube is a tool through which we can evaluate our code. Here, for demo purposes, we are going to evaluate the web API which is built on .NET Core. Let's see step by step implementation. In order to run SonarQube, we need to install JAVA in our local system.   Refer to the below link to download JAVA installer and install JAVA. https://www.oracle.com/technetwork/java/javase/downloads/index-jsp-138363.html Configure the 'PATH' system variable under environment variables Go to Control Panel > System > Advanced System Settings, it will open the System Properties window. Click on the "Environment Variables" button. Click on the "View" button under User Variables. Give the variable name as 'JAVA_HOME'. The variable value will be your JDK path where you installed JAVA. Select path variable under system variable and click o
