In this article, I will explain how to use Progress Bar control in Windows.Forms applications. Progress Bar control is an important control; many applications need to include progress bar control in them. Designing a Progress Bar in Windows.Forms application is simple and it can be used in the application. Follow the steps given below to create a Progress Bar.

Step 1
Open Visual Studio 2017--->NewProject--->Windows.Forms application and name it Progress Bar.

Step 2
From the toolbox, drag and drop the button control into the form and right click on the button. Select property. Here, you can change the text, font, and the name of the button. In my Project, I changed the text of the button to "Load Progress Bar".

Step 3
Now, drag and drop the Progress Bar from the Toolbox to Windows.Forms in Visual Studio. Right-click on the progress bar and select property. Here also, you can change the text, font, and name of the Progress Bar. Progress bar is a control that applications use to indicate the progress of a lengthy operation, such as calculating the result, downloading a large file from the web etc. Progress Bar control is used whenever an operation takes more than a short period of time. The maximum and minimum properties define the range of values to represent the progress of a task.

Step 4
Now, drag and drop the timer control from the toolbox to the Windows.Forms in Visual Studio. The detailed function of Timer control is already explained in my previous article.

Step 5
Now, it's time to code. Follow the code given below in the screenshot for the Button-Click event.

Step 6
Now, follow the code given below in the screenshot for the timer click event. A progress bar control is used to display the progress of some activity. I have added a timer control to the form and on the timer tick event handler, I increment the value of the progress bar.

Output
Compile and run the project. The final output of the project obtained is as given below in the screenshot. As the "Load Progress bar" button is pressed, the progress bar starts to display the progress.

Summary
Hope you all understand the working of a progress bar. In case of any problem or error, please feel free to comment down below. In my next article, I will explain how to install NuGet Packages and work with Circular progress bar control in Windows.Forms application.

It is often required to work with Node.JS and NPM package installer behind the proxy. When trying to install npm packages behind the proxy, you may come across the error, given below.

To resolve exceptions, shown above, http_proxy and https_proxy configurations needs to be done for NPM. The step by step guidance is given below to perform the configuration on Windows machine-Go to C:\User\{User} directory.

• if .npmrc file exists then open it in notpad editor else create .npmrcfile.
• Add the lines, given below to the file for your valid AD domain user. proxy=http://domain\\username:password@ip:port
• Add the lines, given below for Non AD user proxy=http://username:password@ip:port
• Save .npmrc file
• Try to use npm install now. It should work without any error.

The sample contents of .npmrc file are shown below.

A message exchange pattern means how the client and WCF service exchange the message (data) internally. There are a total three types of patterns,

• Request – Reply
• One Way
• Duplex

We will learn each of them in detail below.

Request – Reply
In request reply pattern client sends the request to WCF service and waits for the response from the WCF service. Until they get a reply no other process runs. After getting a response from the WCF service they will continue its work. If WCF service has a method with void return type then the client will wait for the reply.

So in this pattern if any error occurs then it will directly display on the client side. Default pattern for any methods is request – reply. You can declare any method to request a reply by assigning ‘IsOneWay=false’ as show below.
    [ServiceContract] 
            public interface IMessageExchPatterns 
            { 
                [OperationContract] 
                string GetDataRequestReply (string name); 
    }
OR
    [ServiceContract] 
            public interface IMessageExchPatterns 
            { 
                [OperationContract(IsOneWay=false)] 
                string GetDataRequestReply (string name); 
    } 
As shown in the above example you can declare request reply pattern in two ways.

One Way
In One way pattern client sends the data or request to WCF service but it doesn't wait for any reply from the service and also service doesn't send any reply to them, so here the client will not show any thing on service then will only send the message to service. It doesn't check if that message reaches the service or not. You can set this pattern by IsOneway=true.

Example
    [ServiceContract] 
            public interface IMessageExchPatterns 
            { 
                [OperationContract(IsOneWay=true)] 
                void GetDataOneWay (string name) 
    } 

Duplex
In Duplex pattern you have to predict that there are  two clients (client-1, Client-2); client-1 makes request to service and then service will sent request to client-2 and then service gets response from client-2 and give this replay to client-1.

Here this pattern is to use the callback method for the internal (client to client ) communication. So here we have to define the callback interface as show below,
    [ServiceContract(CallbackContract=typeof(IMessageExchPatternsCallback))] 
            public interface IMessageExchPatterns 
            { 
                [OperationContract(IsOneWay = false)] 
                string GetDataRequestReply(string name); 
     
                [OperationContract(IsOneWay=true)] 
                void GetDataOneWay(string name); 
     
            [OperationContract] 
                void GetDataDuplex(string name); 
            } 
     
            public interface IMessageExchPatternsCallback 
            { 
                [OperationContract] 
                void SendData(string name); 
    } 

As shown in above example we specify the,
    [ServiceContract(CallbackContract=typeof(IMessageExchPatternsCallback))] 
Here we specify the call back contract for the interface. This callback interface (IMessageExchPatternsCallback) is implementing on client side.
    [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Reentrant)] 
    public class MessageExchPatterns : IMessageExchPatterns 
    { 
             
            public string GetDataRequestReply(string name) 
            { 
                return "You have enter : " + name; 
            } 
     
            public void GetDataOneWay(string name) 
            { 
                Console.Write("You have enter : " + name); 
            } 
     
            public void GetDataDuplex(string name) 
            { 
                OperationContext.Current.GetCallbackChannel<IMessageExchPatternsCallback>().SendData("Hi, " + name); 
            } 
    } 

Now host this service on console application
ServiceHost host = new ServiceHost(typeof(MessageExchPatterns.MessageExchPatterns)); 
host.Open(); 
Console.Write("Service started..."); 
Console.Read(); 

Now create client application with Window form application as below.

Write code as shown below,
[CallbackBehavior(UseSynchronizationContext = false)] 
public partial class Form1 : Form,ServiceReference1.IMessageExchPatternsCallback 
    { 
        public Form1() 
        { 
            InitializeComponent(); 
        } 
 
        InstanceContext instanceContext; 
        private void button1_Click(object sender, EventArgs e) 
        { 
            
            ServiceReference1.MessageExchPatternsClient clnt = new ServiceReference1.MessageExchPatternsClient(instanceContext); 
            label1.Text = clnt.GetDataRequestReply(textBox1.Text); 
        } 
 
        void ServiceReference1.IMessageExchPatternsCallback.SendData(string name) 
        { 
            Label3.Text = name; 
        } 
 
        private void button2_Click(object sender, EventArgs e) 
        { 
             
MessageExchPatternsClient clnt = new MessageExchPatternsClient(instanceContext); 
            clnt.GetDataOneWay(textBox2.Text); 
        } 
 
        private void button3_Click(object sender, EventArgs e) 
        { 
ServiceReference1.MessageExchPatternsClient clnt = new ServiceReference1.MessageExchPatternsClient(instanceContext); 
            clnt.GetDataDuplex(textBox3.Text); 
        } 
 
        private void Form1_Load(object sender, EventArgs e) 
        { 
            instanceContext  = new InstanceContext(this); 
        } 
    } 

Now run the WCF service host. Then run client application.

In this tutorial, i will tell you about how to Remove White Line Or Space In Visual Studio.  I know this a not a new concept but i seen many times in my office guys lots of time spent remove the white space or lines. I know that this type of code snippet but this code snippet is very useful for everyone experienced or fresher developer. when we make a function or develop code am sure some extra lines add in code. Like this way,

{ 
             button2.Text = "Please Select Me..."; 
         } 
  //Blank Line
  //Blank Line
         }; 
 
     } /// End button2 scope here.  
 
  //Blank line
// Blank line
 
     private void Save_Click(object sender, EventArgs e) 
     { 

suppose this type of blank lines on every pages. if you want manage your code that's no possible remove line one by one. Thank to Microsoft to give to option remove all blank line.

Open the find and replace pop up windows and past the code "^(?([^\r\n])\s)*\r?$\r?\n" in find textbox.

Today, let me tell you about binding table with JSON String using Angular.This is a really easy Javascript function, that helps to convert Json String to a hypertext mark-up language Table by using AngularJS Frameworks. Define a well structured Json string as shown below, this Json string contains the information of two IT departments with the following code:

var dept1 = {  
    "data": [{  
            "Name": "Robert",  
            "City": "London",  
            "Country": "United Kingdom"  
    },  
            {  
            "Name": "Scott",  
            "City": "Manchester",  
            "Country": "United Kingdom"  
    },  
            {  
            "Name": "Rebecca",  
            "City": "Liverpool",  
            "Country": "United Kingdom"  
    },                    
            {  
            "Name": "Peter",  
            "City": "Bristol",  
            "Country": "United Kingdom"  
    },                    
            {  
            "Name": "Thomas",  
            "City": "Leeds",  
            "Country": "United Kingdom"  
    }]  
}  
var dept2 = {        
    "data": [  
            {  
            "Name": "Ethan",  
            "City": "Cardiff",  
            "Country": "United Kingdom"  
    },               
            {  
            "Name": "David",  
            "City": "Southampton",  
            "Country": "United Kingdom"  
    },                
            {  
            "Name": "Suzan",  
            "City": "Norwich",  
            "Country": "United Kingdom"  
    }  
]  
}  

JS (Functions)
var app = angular.module('myApp', []);  
 
app.controller('employees', function($scope, $http) {  
    $scope.names = dept1.data;  
    $scope.next = function() {  
        $scope.names = dept2.data;  
    }  
     $scope.prev = function() {  
        $scope.names = dept1.data;  
    }  
});

HTML
<div ng-app="myApp" ng-controller="employees">    
    <input type="button" value="Development" ng-click="prev();">    
          <input type="button" value="Testing" ng-click="next();">    
    <table>    
        <tr ng-repeat="x in names">    
            <td>{{ x.Name }}</td>    
            <td>{{ x.Country }}</td>    
        </tr>    
    </table>    
</div>               

CSS
table {    
    border-collapse: collapse;    
    width: 100%;    
}    
th, td {    
    padding: 0.25rem;    
    text-align: left;
