European Visual Studio 2017 Hosting - HostForLIFE.eu :: Using the BackgroundWorker component

clock September 20, 2018 11:12 by author Peter

The BackgroundWorker allows you to execute operations that take a long period of time such as database transaction or file downloads, asynchronously on a separate thread and allow the user interface to remain responsive.


Start an Operation in the Background
First, you need to add an instance of the BackgroundWorker component to your application, if you use visual studio, just drag it from the toolbox to your application or you can create it manually as follow:
BackgroundWorker backgroundWorker1 = new BackgroundWorker(); 

To start the operation in the background you have to call the RunWorkerAsync() method of the BackgroundWorker, when you call this method the BackgroundWroker starts the execution of the background operation by raising the DoWork event, the code in the DoWork event handler is executed on a separate thread.
BackgroundWorker backgroundWorker1 = new BackgroundWorker(); 
//start the operation on another thread 
private void btnStart_Click(object sender, EventArgs e) 

    backgroundWorker1.RunWokerAsync(); 

//DoWork event handler is executed on a separate thread 
private void backgroundWorker1_DoWork(object sender, DoWorkeventArgs e) 

    //a long running operation 
    Thread.Sleep(5000); 


You can send a parameter to the background operation using the RunWorkerAsync() method. You can receive this parameter by using the Argument property of the instance of DoWorkEventArgs in the DoWork event handler then you cast it to use it in the background operation.

BackgroundWorker backgroundWorker1 = new BackgroundWorker(); 
//start the operation on another thread 
private void btnStart_Click(object sender, EventArgs e) 

    backgroundWorker1.RunWokerAsync(2000); 

//DoWork event handler is executed on a separate thread 
private void backgroundWorker1_DoWork(object sender, DoWorkeventArgs e) 

    int input = (int)e.Argument; 
    //a long running operation 
    Thread.Sleep(input); 


Reporting progress of a background operation using BackgroundWorker

By using the BackgroundWorker you have the ability to report progress updates of the executing operation. To use this options you must set the WorkerReportsProgress to true.

To start report progress you call ReportProgress() method and use it to pass a parameter that have the value of the percentage of the progress that have been completed. This method raises the BackgroundWorker.ProgressChanged event. In the event handler of the ProgressChanged you can recieve the value of the progress precentage on the main thread using the ProgressPercentage property of the instance of ProgressChangedEventArgs.

BackgroundWorker backgroundWorker1 = new BackgroundWorker(); 
backgroundWorker1.WorkerReportsProgress = true; 
//start the operation on another thread 
private void btnStart_Click(object sender, EventArgs e) 

    backgroundWorker1.RunWokerAsync(); 

//DoWork event handler is executed on a separate thread 
private void backgroundWorker1_DoWork(object sender, DoWorkeventArgs e) 

    //a long running operation 
    for (int i = 1; i < 11; i++) 
    {    
        Thread.Sleep(2000); 
        backgroundWorker1.ReportProgress(i*10); 
    } 

private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e) 

    progressBar1.value = e.ProgressPercentage; 


Canceling a background operation using BackgroundWorker

With the BackgroundWorker you have the ability to cancel the background operation, to do this you first must set WorkerSupportsCancellation property to true.

The next step is to call the CancelAsync() method by doing so you set the CancellationPending property to true, by polling the CancellationPending property you can determine whether or not to cancel the background operation.

BackgroundWorker backgroundWorker1 = new BackgroundWorker(); 
backgroundWorker1.WorkerSupportsCancellation = true; 
//start the operation on another thread 
private void btnStart_Click(object sender, EventArgs e) 

    backgroundWorker1.RunWokerAsync(); 

//a buttun to cancel the operation 
private void btnCancel_Click(object sender, EventArgs e) 

    backgroundWorker1.CancelAsync(); 

//DoWork event handler is executed on a separate thread 
private void backgroundWorker1_DoWork(object sender, DoWorkeventArgs e) 

    //a long running operation 
    for (int i = 1; i < 11; i++) 
    { 
        Thread.Sleep(2000); 
        backgroundWorker1.ReportProgress(i*10); 
        if(backgroundWorker1.CancellationPending) 
        { 
            e.cancel = true; 
            return; 
        } 
    } 


Alert the user in the completion of the background operation
When the background operation completes, whether because the background operation is completed or canceled, the RunWorkerCompleted event is raised. You can alert the user to the completion by handling the RunWorkerCompleted event.

You can determine if the user canceled the operation by using the Cancelled property of the instance RunWorkerCompletedEventArgs.
BackgroundWorker backgroundWorker1 = new BackgroundWorker(); 
//start the operation on another thread 
private void btnStart_Click(object sender, EventArgs e) 

    backgroundWorker1.RunWokerAsync(); 

//a buttun to cancel the operation 
private void btnCancel_Click(object sender, EventArgs e) 

    backgroundWorker1.CancelAsync(); 
}  
//DoWork event handler is executed on a separate thread 
private void backgroundWorker1_DoWork(object sender, DoWorkeventArgs e) 

    //a long running operation 
    for (int i = 1; i < 11; i++) 
    { 
        Thread.Sleep(2000); 
        backgroundWorker1.ReportProgress(i*10); 
        if (backgroundWorker1.CancellationPending) 
        { 
            e.Cancel = true; 
            return; 
        } 
    } 
}  
private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) 

    if(e.Cancelled) 
    { 
        MessageBox.Show("Operation Cancelled"); 
    } 
    else 
    { 
        MessageBox.Show("OperationCompleted"); 
    } 


Return a value from the background operation
You can return a value from the background operation that in the DoWork event handler using the Result property of the DoWorkEventArgs instance, and you can receive it in the RunWorkerCompleted event handler using the Result property of the RunWorkerCompletedEventArgs instance.

BackgroundWorker backgroundWorker1 = new BackgroundWorker(); 
//start the operation on another thread 
private void btnStart_Click(object sender, EventArgs e) 

    backgroundWorker1.RunWokerAsync(); 

//DoWork event handler is executed on a separate thread 
private void backgroundWorker1_DoWork(object sender, DoWorkeventArgs e) 

    //a long running operation here 
    Thread.Sleep(2000); 
    //return the value here 
    e.Result = 10; 

private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e) 

    //recieve the return value here 
    int returnValue = (int)e.Result; 



Node.js Hosting Europe - HostForLIFE.eu :: How to Use Inheritance in Node.js ?

clock September 12, 2018 08:29 by author Peter

In this post we'll take a glance on inheritance of objects in Node.js. we'll learn to use utility module to achieve inheritance in Node.js. but confine mind that you simply will write plain JavaScript to attain inheritance in Node also.

You'll use Object.create() to inherit one object to a different in Node.js also.

In this post we'll learn to use util module to achieve inheritance in Node.js. First, you should to import util module in your application.
var util= require(‘util’);

After importing util module, allow us to say you have got an object as below,
function Student()

 this.name = "G Block";
 this.age = 40;
};


Just for demonstration allow us to add function in object using prototype,
Student.prototype.Display= function(){
 console.log(this.name + " is " + this.age + " years old");
 };


Next we tend to we progressing to make ArtsStudent object which is able to inherit Student object.
function ArtsStudent()
{
 ArtsStudent.super_.call(this);
 this.subject = "music";
 }; 
util.inherits(ArtsStudent,Student);


Second line of code in ArtsStudent object is very important,
ArtStudent.super_.call(this);

If you don’t call constructor of parent object as shown in above code snippet then on making an attempt to access properties of parent object will come undefined. In last line ArtStudent inherits Student using util.inherits() function ,

util.iherits(ArtsStudent,Student);

Next you can create instance of ArtsStudent and call function of parent object as below,
var a = new ArtsStudent();
a.Display();


Inheritance will be chained to any order. If you want you can inherit object from ArtsStudent as well. Inherited object will contain properties from both ArtsStudent and Student objects. So let us consider one more example,
function ScienceStudent()
{
 ScienceStudent.super_.call(this);
 this.lab = "Physics";
}
util.inherits(ScienceStudent,ArtsStudent);
var b = new ScienceStudent();
b.Display();

On this example ScienceStudent object inherits both Student and ArtsStudent objects. With this example, you can work with inheritance in Node.js using util module. I hope it works for you!

Windows Server 2016 SSD Hosting - HostForLIFE.eu :: PowerShell Script To Reading SQL Data, Creating CSV File And Push To SFTP/FTP Path?

clock September 7, 2018 11:16 by author Peter

The below powershell cmdlets are used to create csv files by querying the SQL server.

All the variables containing the server name and DB details:
    #Variable to hold variable 
    $SQLServer = "XX.XX.XXX.XX" 
    $SQLDBName = "TestDB" 
    $uid ="domain\userID" 
    $pwd = "password123"  
    #SQL Query 
    $SqlQuery = "SELECT * from tableName;" 
    $SqlConnection = New-Object System.Data.SqlClient.SqlConnection 
    $SqlConnection.ConnectionString = "Server = $SQLServer; Database = $SQLDBName; Integrated Security = True;" 
    $SqlCmd = New-Object System.Data.SqlClient.SqlCommand 
    $SqlCmd.CommandText = $SqlQuery 
    $SqlCmd.Connection = $SqlConnection 
    $SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter 
    $SqlAdapter.SelectCommand = $SqlCmd  
    #Creating Dataset 
    $DataSet = New-Object System.Data.DataSet 
    $SqlAdapter.Fill($DataSet) 
    $DataSet.Tables[0] | out-file "\\location\test.csv" 


Note
When Intergrated Security ="true" is used, the cmdlets use current logged in user credentials - network credentails if Integrated Security ="false" we need to use the declared $uid and $pwd while establishing the connection.

The File is saved in the location or FTP path as test.csv
The SFTP is Secured FTP; the following powershell command helps to move any file to the SFTP location and it needs "Posh-SSH module" We need to install this module.https://github.com/darkoperator/Posh-SSH

The Powershell variable mentioned in the below code snippnet stores all the details of the SFTP or FTP server, where the files need to be moved.
    #Declaring Variable 
    $sourceSFTPIP = "xx.xx.xxx.xx" 
    #IP address of the SFTP server 
    $LocalFilePath = "C:\test.csv"; 
    $SFTPPath = ".\sharedFilePath\"  
    # folder location inside SFTP server 
    $secpasswd = ConvertTo - SecureString "password" - AsPlainText - Force 
    # the below object is used to key in the username and password automatically rather than promt the user to username and password 
    $mycreds = New - Object System.Management.Automation.PSCredential("username", $secpasswd) 
    # Module need to use SFTP Path 
    Install - Module - Name Posh - SSH# get sftp password this command can be used 
    if user need to feed in the user name and password at the time of running the script 
    # $credential = Get - Credential# Creating PS session to be used 
    $session = New - SFTPSession - ComputerName $sourceSFTPIP - Credential $mycreds - AcceptKey 
    # Move File using ps session 
    Set - SFTPFile - SessionId $session.SessionId - LocalFile $LocalFilePath - RemotePath $SFTPPath 
    $session.Disconnect() 


We need to disconnect the session that was created to do this operation. Once it has run,  the file that is present in sharepath is moved to the SFTP server location.



European Visual Studio 2017 Hosting - HostForLIFE.eu :: Visual Studio IntelliCode Preview Available

clock August 24, 2018 11:08 by author Peter

Recently, Microsoft has announced the availability of Preview of Visual Studio IntelliCode in its Build 2018 developer’s conference. This is a new experimental tool for Visual Studio users bringing more of the company’s artificial intelligence smart to software development.

It is a set of AI-assisted capabilities which improves the developer’s productivity with features like contextual, IntelliSense and focused reviews for pull requests.
 
The company states -
“The IntelliCode extension augments productivity features in Visual Studio 2017 with insights based on understanding your code combined with machine learning. The first iteration of this extension enhances your IntelliSense experience by sorting completion items—which are recommended in your code context--to the top of the list.”
 
According to the company, IntelliCode is now applicable only for C# code but in future, it will be upgraded to support more languages.

 



Windows Server 2016 SSD Hosting - HostForLIFE.eu :: How To Securely Delete Files From Your Servers?

clock August 15, 2018 11:40 by author Peter

Do you know what happens when you delete a file in a GUI or run rm file.txt on the command line? If you said the file is deleted, you are only half right. In fact, the data stays just where it was before you “deleted” it. You can’t see it because the link the operating system used to identify the file and show it to you no longer exists. But the data is untouched until the operating system uses the space for a different file.

It’s easy to restore data that has not been securely deleted. That’s bad news if the hard drive the data is on is sold, leased to someone else, or thrown in the trash. There are business, security, and legal consequences if server data is not securely deleted.

The only way to securely delete data is to overwrite it. You could also destroy the drive, but businesses typically lease servers that they don’t have physical access to or they own. They need to be able to securely delete data remotely. A quick rm doesn’t cut it.

Before I outline the best way to securely delete a file or volume, a word of warning. If you do this, the data will be gone forever — that’s the point. Before running any of these commands, make sure you really mean it.

Securely Deleting A File

As I have already said, rm removes directory entries. It does not delete data. To securely delete the data, you must use a tool that both removes the link and overwrites the data.

One such tool is shred, which will repeatedly overwrite the file’s data with random bytes.

shred -u file.txt

Shred overwrites the file three times with random data, although you can specify how many times the data is overwritten with the -n option. If you don’t use the -u option, shred will overwrite the data but it won’t remove the file.

Securely Deleting A Drive

The shred utility can securely erase drives, but we’ll explore an alternative.

Before running these commands, check that you have correctly identified the drive you want to erase. The command will run on the boot and root drives without warning.

Linux represents drives as files. For example, the file /dev/sda1 represents the “first” drive on your server. The dev directory is not a normal directory, but a collection of special files representing devices connected to the server.

To see the drives connected to a server, run this command,

`fdisk -l`

Identify the drive that you intend to erase all data from and take note of the special filename. We’re going to use dd to overwrite the data on this drive with either random data or zeroes. The dd command “converts and copies a file”.

In this case, we’re going to take data from a special file and overwrite our target drive with it. Linux provides several special files that generate a stream of data, including /dev/zero and /dev/urandom, which contain lots of zeros and pseudorandom data respectively.

dd if=/dev/urandom > /dev/ss__ # replace __ with drive number

Here, we designate /dev/random as the input file and direct its data to overwrite the drive. This will destroy all data on the drive.

For added security, you can repeat the dd command several times or alternate between random data and zeros with:

dd if=/dev/zero of=/dev/sd__ # replace __ with drive number

On modern high-density drives, multiple passes are usually not necessary, but it doesn’t hurt.

Limitations

There are some limitations to this approach that you should be aware of. If the data is being backed up to a different drive, it may remain accessible. If the drive uses a modern journaling filesystem like ext4, some data may not be erased properly. SSD wear leveling can also interfere with secure deletion.

For sensitive data, it may be best to use an encrypted volume rather than relying on secure deletion. The data from an encrypted volume cannot be recovered without the key even if it has not been securely deleted.



European Visual Studio 2017 Hosting - HostForLIFE.eu :: Customize Visual Studio Code Shortcuts

clock August 10, 2018 11:13 by author Peter

A couple of months ago, I started using Visual Studio Code for my development activities. I found myself very uncomfortable with the keys and shortcuts. I have been using Visual Studio for more than 6 years now. So, I was very comfortable with the keys and shortcuts of that. The difference in shortcuts was creating a challenge for me. Should I remember a different set of shortcuts for VS Code? Should I start using some other editor?

Then, I started to customize the VS Code shortcuts. If you are also facing the same issues, then it's time you should consider customizing the Visual Studio Code shortcuts. It’s not worth spending energy on remembering a new set of shortcuts for a specific editor. Following are some tips,

  1. Open keyboard shortcuts in Visual Studio Code and update the shortcuts as per your need.
    Press ctrl+K, ctrl+s to open the keyboard shortcut window. This looks something like below.
  2. You can see the Edit button on the right side of the row (highlighted one). On click of the Edit button, it will ask you to change the combination you want to execute the command for.

    You can change the combination for your convenience.

  1. You can open keybindings.json file and update as per your need.
    To open the keybindings.json, you need to open the Keyboard shortcuts first by pressing ctrl+k, ctrl+s. You can click on the keybindings.json file.
  2. This will open the default keybindings. This is a JSON file which can be modified to get your desired shortcuts.
  1. You can have your custom JSON file with your shortcut commands.
    When you open default keybindings.json file in the right-hand side window, it opens a keybindings.json file where you can write your custom keys and commands.

Given are a couple of commands I have added in the keybindings.json file to work with the VS Code. Please let me know your feedbacks/ comments. Are there better ways I am not just aware of?



Node.js Hosting in Europe - HostForLIFE.eu :: Forgot Password Email Notification Using Node js

clock August 8, 2018 09:22 by author Peter

Before starting the code you need an account in send grid which will send the notification to your mail. Generally we use email notifications for forget passwords in your applications. You can follow the below steps to get the task done and if you have any queries please leave a comment below.

We require a few modules from npm to send the notification through the mail.

  • npm install formidable
  • npm install crypto
  • npm install async
  • npm install nodemailer

In my router.js file the following code will be present 
app.route('/forgotpasswordResponse') 
.post(userCtrl.forgotpasswordResponse); 


When I run my services and hit the above Url  from postman it will take you to the forgotpasswordResponse method. We are using post method in postman where we need to pass Email id as parameter

In forgotpasswordResponse my code is somthing like this,
exports.forgotpasswordResponse = function(req, res, next) { 

var input=req.body; 
//console.log(input); 
async.waterfall([ 
function(done) { 
    crypto.randomBytes(20, function(err, buf) { 
        var token = buf.toString('hex'); 
        done(err, token); 
    }); 
}, 
function(token, done) { 
    MongoClient.connect(url, function(err, db){  
        var dbo = db.db("Here is your DB Name"); 
        //console.log(req.body.Email); 
        var query = { Email : req.body.Email }; 
        dbo.collection('CLC_User').find(query).toArray(function(err,result){ 
            if(result.length == 0){ 
                req.flash('error', 'No account with that email address exists.'); 
            } 
            var myquery = { Email: result[0].Email }; 
            var newvalues = { $set: {resetPasswordToken: token, resetPasswordExpires: Date.now() + 3600000 }}; 
            dbo.collection("CLC_User").updateOne(myquery, newvalues, function(err, res) { 
                if (err) throw err; 
                console.log("1 document updated"); 
            }); 
             

           // console.log(result[0].Email); 
            done(err, token, result); 
        }); 
    }); 
}, 
function(token, result, done,Username,password) { 
    var emailVal = result[0].Email; 
    console.log(emailVal); 
    var Username=""; 
    var password=""; 
    MongoClient.connect(url, function(err, db){  
    var dbo = db.db("Here willbe your db name"); 
    dbo.collection('Accountsettings').find().toArray(function(err,result){ 
        if (err) throw err; 
        Username=result[0].UserName; 
        password=result[0].Password; 
       // console.log(Username); 
       // console.log(password); 
           // res.json({status : 'success', message : 'Records found', result : result}); 
     

    // console.log(Username); 
    var smtpTransport = nodemailer.createTransport({ 
        service: 'SendGrid', 
        auth: { 
          user: Username, 
          pass: password 
        } 
      }); 

    const mailOptions = { 
        to: emailVal, 
        from: '[email protected]', 
        subject: 'Node.js Password Reset', 
        text: 'You are receiving this because you (or someone else) have requested the reset of the password for your account.\n\n' + 
            'Please click on the following link, or paste this into your browser to complete the process:\n\n' + 
            'http://' + req.headers.host + '/reset/' + token + '\n\n' + 
            'If you did not request this, please ignore this email and your password will remain unchanged.\n' 
    }; 
    smtpTransport.sendMail(mailOptions, function(err) {                
        console.log("HI:"+emailVal); 
        res.json({status : 'success', message : 'An e-mail has been sent to ' + emailVal + ' with further instructions.'});             
        done(err, 'done'); 
    }); 
}) 
}); 

 
], function(err) { 
if (err) return next(err); 
 
}); 


In my case  I am using waterfall methologie for this method with will execute acyn in method, In the above code initially I am updating the collection with resetPasswordToken and resetPasswordExpires using email id and getting my send  grid credentials from db form  Accountsettings collections. If you can observe in mailOptions text "req.headers.host" will be the link which will get in you mail with token.

When you click on Url which you got in the email it will redirect you to another page to set the password.

Again we need to go to route.js and the code will be some thing like this. It will take to html page which we can reset the password,
app.route('/reset/:token') 
.get(Resetpassword.resetpasswordResponse);  

This time I am passing the token which I stored in db as "resetPasswordToken". Now it will take you to resetpasswordResponse method and the code is below,
exports.resetpasswordResponse = function(req, res) { 
console.log("welcome"); 
MongoClient.connect(url, function(err, db){ 
var dbo = db.db("Here is you db"); 
dbo.collection('CLC_User').findOne({resetPasswordToken: req.params.token, resetPasswordExpires: { $gt: Date.now() } }, function(err, user) { 
    if (!user) { 
        res.json({message: 'Password reset token is invalid or has expired.'}); 
    }else{ 
        console.log("coming"); 
        fs.readFile("api/Controllers/resetpassword.html", function (error, data) { 
            console.log("its working"); 
            if (error) { 
                console.log(error); 
                res.writeHead(404); 
                res.write('Contents you are looking are Not Found'); 
            } else { 
                //res.writeHead(200, { 'Content-Type': 'text/html' }); 
                res.write(data); 
            } 
            res.end(); 
        }); 
    } 
}); 
}); 


Your html code in resetpassword.html will be like this,
<!DOCTYPE html> 
<html> 
<head> 
<title>Reset Password</title> 
<script src="https://code.jquery.com/jquery-1.12.4.js"></script> 
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script> 
</head> 
<body> 
<h4 class="postdata" style="text-align:center;"></h4> 
<div class="main-agileits"> 
<h2 class="sub-head">Reset Password</h2> 
<div class="sub-main">     
    <form method="post"> 
        <span class="senddata"></span><br><br> 
             
        <input placeholder="Enter Password" name="password" class="password" type="password" required=""><br><br> 

        <input placeholder="Confirm Password" name="confirmpassword" class="confirmpassword" type="password" required=""><br><br> 
         
        <input type="submit" name ="submit" value="RESET PASSWORD"> 
         
    </form> 
</div> 
</div> 
</body> 
</html> 


<script type="text/javascript"> 

$( document ).ready(function() { 
$("input[name='submit']").on("click", function(){ 
$(".senddata").html(""); 
var url = window.location.href; 
var password = $('.password').val(); 
var confirmpassword = $('.confirmpassword').val(); 

if( password == confirmpassword){ 
    $.post(url,{Password : password},function(result,status){ 
    var msg = result.status; 
    var msgdata = result.message; 
    if(msg == "success"){ 
        $(".postdata").html(msgdata); 
        $(".main-agileits").css("display","none") 
    }else{ 
        return false; 
    } 
}); 
}else{ 
    $(".senddata").html("Passwords did not match"); 
}        
return false; 
}); 

}); 

</script>


the next step is send the Email notification after changing the password.The code is
app.route('/reset/:token') 
.post(setpassword.setpasswordResponsemail); 

exports.setpasswordResponsemail = function(req, res) { 
async.waterfall([ 
function(done) { 
    MongoClient.connect(url, function(err, db){ 
        var dbo = db.db("Your Db name goes here");  
        dbo.collection('CLC_User').findOne({resetPasswordToken: req.params.token, resetPasswordExpires: { $gt: Date.now() } }, function(err, user) { 
            if (!user) { 
                res.json({message: 'Password reset token is invalid or has expired.'}); 
            } 
            //console.log(user); 
            var myquery = { resetPasswordToken: req.params.token }; 
            var newvalues = { $set: {Password: req.body.Password,resetPasswordToken: undefined, resetPasswordExpires: undefined, modifiedDate : Date(Date.now()) }}; 
            dbo.collection("CLC_User").updateOne(myquery, newvalues, function(err, result) { 
                if (err) throw err; 
                //console.log("result ======" + result);

European Visual Studio 2017 Hosting - HostForLIFE.eu :: How To Open Browser Or Run Program Directly From Visual Studio Code

clock August 3, 2018 09:39 by author Peter
Visual Studio Code is a Editor for running your code efficiently. It is now very popular editor for running your Source Code. Its features are very awesome and anyone can shift to Visual Studio Code. The best part is, it is free to use and free to download. The developers who are get bored from the OLD, Simple looking, Boring HTML code Editors can also shift to Visual Studio Code. It is Developed by Microsoft.Nowadays developers facing problems while running a simple HTML code directly from the Editor as Visual Studio Code does not have any in-built direct feature to run the code like other Editors or its own Visual Studio. But here is a solution to run the code directly from the Editor.

Start the Visual Studio Code Editor. On the left panel click on the Extensions Tab. Or Press (Ctrl + shift + X)


Then in the search bar search for "open in browser". You will get a list of plugins. For simplicity select first plugin and click install

After completion of the installation process it will ask for RELOAD.Just RELOAD the VSC(Visual Studio Code) Editor it will not cause any damage to your unsaved data.

After reloading just right click on your html file and select "Open in Other Browsers".

Select your required Browser and See your Output.

Another way to run is a Short cut key from your keyboard is (Alt+Shift+B).



Windows Server 2016 SSD Hosting - HostForLIFE.eu :: Streaming Logs Using Windows PowerShell

clock July 27, 2018 11:21 by author Peter

Log data helps technical personnel quickly drill down on application related issues including:

 

  • Pinpointing areas of poor performance
  • Assessing application health and troubleshooting
  • Diagnosing and identifying the root cause of application installation and run-time errors

There are a lot of tools available in the market which help you stream logs. But with most of them, I have personally experienced if they are easy to use they are paid and most of open source is too complex to configure. In this blog, I will explain how you can implement a simple log streaming tool using Powershell. This is more of a dev/debug helper tool, although if you invest time in the building then you can take it to a product level tool.
To start with,  below is a simple one-line Powershell which will read log file data in real time. The best part is it will WAIT for any more logs to be written on file and will stream it as soon as it completes on the file.

Get-Content "****LOG FILE PATH***" -WAIT

To take it to the next level let's manipulate the logs written before they are presented on screen. In the below code sample if you provide a log with the message containing "*" then the script will change all "*" to "@" before presenting.

Sample log message: INFO InfoLog - ***************CONFIG READ***************
$file = "*******LOG FILE PATH********"  
Get - Content $file - Wait | ForEach - Object - Begin {  
    $counter = 1  
    $lines = @(Get - Content $file).Count  
} - Process {  
    if ($counter++ - gt $lines) {  
        Write - host $_.ToString().Replace("*", "@")  
    }  
}  


Let's take it a bit further. Suppose we need to present Error type messages to be highlighted with RED. And the rest of the message must be in GREEN.
Sample log message: INFO InfoLog - ***************CONFIG READ****************
Sample log message: ERROR ErrorLog - ************CONFIG READ****************

$file = "*******LOG FILE PATH********"  
Get - Content $file - Wait | ForEach - Object - Begin {  
    $counter = 1  
    $lines = @(Get - Content $file).Count  
} - Process {  
    if ($counter++ - gt $lines) {  
        if ($_.ToString().Contains("ERROR")) {  
            Write - host $_.ToString() - foregroundcolor "red"  
        } else {  
            Write - host $_.ToString() - foregroundcolor "green"  
        }  
    }  
}  


There are endless possibilities and use cases which can be implemented, the sky is the limit.



Windows Server 2016 SSD Hosting - - HostForLIFE.eu :: Dedicated Servers As The Secured Solutions

clock July 25, 2018 11:05 by author Peter

When it comes to the option of dedicated servers, you may find it costly in comparison to other web hosting options. But ultimately, the choice is worth making because plenty of commercial benefits are integrated into this web hosting plan. Let’s see how it is a better option than others web hosting plans.

Better uptime
In dedicated hosting arrangements, the service provider reserves the SLA,  including the solution of hardware failure. The service provider maintains a support team for 24x7. With expert skill sets and ITIL complaint methods you can be sure about a high uptime.

Cost efficiency
This is a cost efficient option. According to the plan, a dedicated hosting service provider is responsible for upgradates and maintenance of hardware for maintaining connectivity, and for offering a friendly physical environment. Under this plan, you as a user have no obligation to pay for the total server room or for employing a service administrator. Under this plan you have to pay for the services you will be using.

Reliable bandwidth
Under this web hosting plan you will get to enjoy higher internet speed. There is no chance to lose the speed as there is no risk of sharing the connection. This will help in faster communication, upload management, and uninterrupted business presence.

Complete control on applications
If you select dedicated web hosting, you will enjoy a complete monopoly of decisions about using site management tools and allied other applications to boost your hosting environment. However, about the tools, you need to get prior approval from your hosting service provider that they will be able to give you backend support to maintain them.

Better security arrangement
Dedicated hosting service offers uninterrupted access to physical server. The security arrangement includes supervision cameras, Biometric Access Control System, round-the-clock patrolling, etc. for improved security. Advanced service providers often provide additional supports like DDos guard, web application firewall, VAPT, and security event management.

These reasons can clearly  justify why Dedicated Server is a better option. It is clearly understood that although expensive, this category of web hosting service offers excellent ROI (Return over investment).
