Setter & Constructor Injection in SPRING : Injecting literal values | DEPENDENCY injection in spring
Dependency injection in spring framework: One of the most important concept that you should not miss. Spring dependency injection is one of the most important features that spring provides us. But why it is so popular? What is dependency injection in spring? why do we need it? If you are a beginner, thinking about these questions and looking forward to a fresh start, this is the right place and the right time to get started. Before you get started with this tutorial you have some dependency as well. Just kidding !! If you are completely new to spring then you need to watch a couple of my other videos which will get you started with spring IOC and dependency injection. Below are the links to those videos. Spring framework tutorial for beginners with examples in eclipse | Why spring inversion of control? https://youtu.be/r2Q0Jzl2qMQ What is dependency injection in spring [ Getting started ] | Spring framework tutorial for beginners https://youtu.be/vLMaFRgZjM0 Ok now we are all set to learn spring’s dependency injection concept and we are going to learn it step by step. So dependency injection is nothing but injecting the dependency and dependency could be in form of anything. It could be a string or primitive type, It could be a class type or it could be in form of collection. As I promised we are going to get started with the concept that will cover how we can inject string and primitive based values using spring framework ( injecting literals using spring). So we have two approaches here to inject a dependency which presents in form of a literal. The first one is using a setter method. So spring could internally use a setter method to inject the dependencies to a class and this approach is called setter injection. The second way using what spring can do a dependency injection using a constructor and this is what we called as a constructor injection. To let spring know that we want to inject the values using a setter method, we have to use a “property" tag and to use a constructor for dependency injection we can use a "constructor-arg”. so let’s cover everything in detail with this tutorial now. #dependencyinjection #setterinjection #constructorinjection Spring dependency injection is also an import feature of Spring IOC which we will be learning from this tutorial onwards with a step by step approach. for more spring framework training videos and spring important concepts consider subscribing to my channel by clicking the below link. https://www.youtube.com/channel/UCpUYkSDJpHug-vfC5S-NXRA?sub_confirmation=1 Stay tuned and like my Facebook page for more. https://www.facebook.com/seleniumexpress/ Music : ----------- credits : - (intro) Adventures by A Himitsu https://soundcloud.com/a-himitsu Creative Commons — Attribution 3.0 Unported— CC BY 3.0 http://creativecommons.org/licenses/b...

Spring Boot Properties File and Profiles Tutorial | Externalised Environment Configuration
Hi, Use Spring Boot to externalise your environment specific runtime configuration. Environment specific configuration is usually stored in properties files, YAML files and command line arguments. In this tutorial i will show you how to specifically configure your application for the environment it is deployed into. Having externalised configuration will allow you to propagate your single generated software artefact through your different environments (E.g. Dev, Test, Production). I first created an application.properties and placed it on the application's CLASSPATH. This is one of four locations Spring Boot will look for the default properties file. Properties configured here will be common for all environments unless explicitly overridden. See Spring Boot Features, 24. Externalized Configuration for properties order. I then created an application-{environment}.properties file for each environment. The {environment} is substituted for the spring profile. This can be set using -Dspring.profiles.active virutal machine argument. This is passed into the application on bootup, so from your deployment YAML file / bash shell script etc. E.g. Set your spring profile per environment: -Dspring.profiles.active=local -Dspring.profiles.active=dev -Dspring.profiles.active=test -Dspring.profiles.active=production This will then loads the common application.properites THEN the environment specific properties file. One of: application-local.properties application-dev.properties application-test.properties application-production.properties Spring will then substitute the properties throughout its configuration of the spring container. Enjoy!

Property binding in Angular 2
Text version of the video http://csharp-video-tutorials.blogspot.com/2017/06/property-binding-in-angular-2.html Slides http://csharp-video-tutorials.blogspot.com/2017/06/property-binding-in-angular-2_19.html Angular 2 Tutorial playlist https://www.youtube.com/playlist?list=PL6n9fhu94yhWqGD8BuKuX-VTKqlNBj-m6 Angular 2 Text articles and slides http://csharp-video-tutorials.blogspot.com/2017/06/angular-2-tutorial-for-beginners_12.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists In this video we will discuss Property binding in Angular with examples. In Part 8, we discussed we can use interpolation to bind component class properties to view template. Another option to achieve exactly the same thing is by using Property binding. In our previous video we have bound imagePath property of the component class to [img] element src property using interpolation as shown below. [img src='{{imagePath}}'/] We can rerwrite the above example, using property binding as shown below. Notice the [img] element src property is in a pair of square brackets, and the component class property is in quotes. [img [src]='imagePath'/] Both Interpolation and Property binding flows a value in one direction, i.e from a component's data property into a target element property. What is the difference between Interpolation and Property binding Interpolation is a special syntax that Angular converts into a property binding. Interpolation is just a convenient alternative to property binding. In some cases like when we need to concatenate strings we have to use interpolation instead of property binding as shown in the example below. [img src='http://www.pragimtech.com/{{imagePath}}' /] When setting an element property to a non-string data value, you must use property binding. In the following example, we are disabling a button by binding to the boolean property isDisabled. [button [disabled]='isDisabled']Click me[/button] If we use interpolation instead of property binding, the button is always disabled irrespective of isDisabled class property value [button disabled='{{isDisabled}}']Click me[/button] Some important points to keep in mind when using Property binding Remember to enclose the property name with a pair of square brackets. If you omit the brackets, Angular treats the string as a constant and initializes the target property with that string. [span [innerHTML]='pageHeader'][/span] With Property binding we enclose the element property name in square brackets [button [disabled]='isDisabled']Click me[/button] We can also use the alternate syntax with bind- prefix. This is known as canonical form [button bind-disabled='isDisabled']Click me[/button] From security standpoint, Angular data binding sanitizes malicious content before displaying it on the browser. Both interpolation and property binding protects us from malicious content. In the example below we are using interpolation. Notice the malicious usage of [script] tag. import { Component } from '@angular/core'; @Component({ selector: 'my-app', template: '[div]{{badHtml}}[/div]' }) export class AppComponent { badHtml: string = 'Hello [script]alert("Hacked");[/script] World'; } Angular interpolation sanitizes the malicious content and displays the following in the browser Hello [script]alert("Hacked");[/script] World In this example below we are using property binding. '[div [innerHtml]="badHtml"][/div]' Property binding sanitizes the malicious content slightly differently and we get the following output, but the important point to keep in mind is both the techniques protect us from malicious content and render the content harmlessly. Hello alert("Hacked"); World

At the moment the count of employees displayed against each radio button are hard-coded with in the EmployeeCountComponent. Here is the code in employeeCount.component.ts file : Notice the values for the 3 properties (all, male, female) are hard-coded. We want the values for these 3 properties to be passed from the container component i.e EmployeeListComponent. export class EmployeeCountComponent { all: number = 10; male: number = 5; female: number = 5; } Convert a component property to an input property using @Input decorator : To be able to pass the values for these 3 properties from the container component to the nested component we need to decorate the properties with @Input() decorator. Decorating a property with @Input() decorator makes the property an input property. Notice I have also removed the default hard-coded values, as we will be passign the values from the parent component i.e EmployeeListComponent. To be able to use the @Input() decorator we will have to first import it from @angular/core. import { Component, Input } from '@angular/core'; @Component({ selector: 'employee-count', templateUrl: 'app/employee/employeeCount.component.html', styleUrls: ['app/employee/employeeCount.component.css'] }) export class EmployeeCountComponent { @Input() all: number; @Input() male: number; @Input() female: number; } Passing data from the parent component to the child component : There are 2 modifications that we need to do in EmployeeListComponent to be able to pass values from the parent component i.e EmployeeListComponent to the child component i.e EmployeeCountComponent. The first change is in EmployeeListComponent TypeScript file as shown below. Notice I have introduced 3 methods that return male employees count, female employees count and total employees count. getTotalEmployeesCount(): number { return this.employees.length; } getTotalMaleEmployeesCount(): number { return this.employees.filter(e =] e.gender === "Male").length; } getTotalFemaleEmployeesCount(): number { return this.employees.filter(e =] e.gender === "Female").length; } Please note : In the filter method we are using tripple equals (===) instead of double equals (==). The table below explains single, double and tripple equals in TypeScript. Operator Use to = Assign a value == Compare two values === Compare two values and their types The second change is in the view template of EmployeeListComponent i.e employeeList.component.html file. Notice with in [employee-count] directive we are using property binding to bind the properties (all, male, female) of the nested component (EmployeeCountComponent) with the 3 methods in the container component (EmployeeListComponent). [employee-count [all]="getTotalEmployeesCount()" [male]="getMaleEmployeesCount()" [female]="getFemaleEmployeesCount()"] [/employee-count] At this point, save all the changes and run the application and we see the correct count of employee next to each radio button. Now, let's add the following new employee object to the to the employees array in EmployeeListComponent. { code: 'emp106', name: 'Steve', gender: 'Male', annualSalary: 7700.481, dateOfBirth: '11/18/1979' } Save changes and reload the web page and notice that All count and Male count is increased by 1 as expected. At the moment when we click the radio buttons nothing happens. In our next video we will discuss how to pass data from the child component to the parent component i.e when a radio button checked event is raised in the child component, we want to know about it in the parent component so we can react and decide which employees to show in the table depending on the selection of the radio button.

Special Property Tax Transactions - Lesson 1
In this video, 7.06 – Special Property Tax Transactions – Lesson 1, the Internal Revenue Code abounds with complex rules concerning transactions in property. In this lesson, Roger Philipp, CPA, CGMA, teaches the essentials of the wash sale rules and the related party property transaction rules. If you sell property such as shares of stock at a loss, then buy identical property within 30 days of the sale, any loss on the initial sale is not deductible. Instead it is treated as an addition to the tax basis of the identical property you now own. Of course, any gain on sale of the original property would still be taxable. Roger then covers related party sales rules. First, Roger explains what are considered related parties for this purpose, comparing and contrasting them with the individual taxation dependency exemption rules. He answers questions such as: Is an aunt or uncle considered a related party? What about a sibling? When an asset is sold to a related party, any gain is taxable but the loss is not deductible. The loss becomes subject to the dual-basis rules in the hands of the individual it was sold to, similar to the dual-basis rules in gift tax, which Roger reviews. Connect with us: Website: https://www.rogercpareview.com Blog: https://www.rogercpareview.com/blog Facebook: https://www.facebook.com/RogerCPAReview Twitter: https://twitter.com/rogercpareview LinkedIn: https://www.linkedin.com/company/roger-cpa-review Are you accounting faculty looking for FREE CPA Exam resources in the classroom? Visit our Professor Resource Center: https://www.rogercpareview.com/professor-resource-center/ Video Transcript Sneak Peek: All right, let's continue on. Let's talk about Special Property Tax Transactions. So we're still in that property tax section. This is where the government says "Hey, we're going to giveth and taketh." What does that mean? It means you made money. "Oh my gosh, that's great, come here buddy, yeah! Let me have my 39.6 percent or my 20 percent long-term or whatever it is.” Or you lost money, so sorry! Not tax deductible." So this is where certain gains are taxable, and losses you just don't get them. For example, a wash sale. A wash sale is kind of you're playing the stock market and you're like "I'm gonna make it big, I'm gonna make it big!" So you buy some stock. You spent 300 bucks on the stock. The stock has gone down in value, so you sell it for 210. I have a $90 loss. Okay, that's great. Are capital gains, capital losses deductible, and taxable? Yes, they are, however, what happens is it's a stock I really like. I like this company, so what I decide to do is I'm going to sell it, take the loss, but then I'm going to right away buy it back. So I buy it back for 200 because I bought it, it went down, and it's still going down. Instead of taking a 90 dollar loss, and then have a new basis of 200, the government says if you buy this, and you buy it within 30 days of buying or selling, that is called a "wash sale" and you basically, if you had a gain, it's taxable, but if you have a loss it's not deductible. What happens is you just have to add it to the basis of the stock. So instead of 200 you get no loss, basis would be 290. So it says here, "losses from wash sales are not deductible. If an asset that has been sold at a loss is repurchased within 30 days of the sale, the loss may not be deducted, but it is added to the base of the repurchased stock. This also applies to purchases obtained of identical assets in the 30 days either before or after." So someone might say in anticipation of selling this "I'm going to buy some more, and then I'll sell this one." Same thing, so here's 30 days, boom! This way, this way, that's called a "wash sale." Loss is not deductible. What if you have a gain? Of course, gains, they're taxable. Losses from related party sales are not deductible, so if I sell something to a related party. If I make money, it's a gain. If I lose money, they go "sorry, it's not deductible." Now, before we go into this in more detail what is considered a related party? And remember we talked about a dependency exemption, right. I like to do what? "C" the IRS jack you out of your money. How do you know if they're a dependent? They have to be a citizen, can't make much income, related to you or live with you the entire year, support and no joint tax return. As far as the related we said, if they're related they don't have to live with you, but if they are ... I'm sorry if they're related they don't have to live with you. If they are not related they have to live with you the entire year like your cousin.

Very important - 15:00 2018 Child Tax Care Credit Changes and Updates (Per HR&Block) Under the new Tax Cuts and Jobs Act (TCJA) the following child tax credit changes will take place in 2018: • The Child Tax Credit under 2018 tax reform is worth up to $2,000 per qualifying child. The age cut-off remains at 17 (the child must be under 17 at the end of the year for taxpayers to claim the credit). • The refundable portion of the credit is limited to $1,400. This amount will be adjusted for inflation after 2018. • The earned income threshold for the refundable credit is lowered to $2,500. • The beginning credit phase out for the CTC increases to $200,000 ($400,000 for joint filers). The phase out also applies to the new family tax credit. • The child must have a valid SSN to claim the nonrefundable and refundable credit. Prior to the TCJA, the taxpayer who was eligible to claim the child’s dependent exemption was also the one eligible to claim the CTC. In turn, the taxpayer and child had to meet several “tests” for the one to be considered the dependent of the other. The TCJA eliminates the dependent exemption itself, but retains the definition of dependent to claim the CTC and other child- or dependent-related tax benefits. For Child Tax Credit reform purposes, this will usually mean that the child must be related to the taxpayer in one of several ways (son, daughter, grandchild, etc.), must live in the taxpayer’s home more than half the year, and must not provide more than half of his or her own support. Special rules apply if the parents are divorced or legally separated. As under previous law, strict due diligence requirements apply for tax professionals who prepare returns with the refundable Child Tax Credit during the 2018 tax year. All changes to the new Child Tax Credit expire after December 31, 2025.

How to pass user actions or user entered values or selections from the child component to the parent component using output properties. 2. We will discuss creating custom events using angular EventEmitter class 3. What is ng-container directive and it's use At the moment when we click the radio buttons, nothing happens. Here is what we want to do. All(6) radio button is clicked - Display all the employees in the table Male(4) radio button is clicked - Display the 4 Male employees in the table Female(2) radio button is clicked - Display the 2 Female employees in the table To achieve this we are going to make use of component output properties. First let's look at the changes required in the nested component i.e EmployeeCountComponent. The changes required in employeeCount.component.ts are comented and self-explanatory // Import Output and EventEmitter import { Component, Input, Output, EventEmitter } from '@angular/core'; @Component({ selector: 'employee-count', templateUrl: 'app/employee/employeeCount.component.html', styleUrls: ['app/employee/employeeCount.component.css'] }) export class EmployeeCountComponent { @Input() all: number; @Input() male: number; @Input() female: number; // Holds the selected value of the radio button selectedRadioButtonValue: string = 'All'; // The Output decorator makes the property an Output property // EventEmitter class is used to create the custom event // When the radio button selection changes, the selected // radio button value which is a string gets passed to the // event handler method. Hence, the event payload is string. @Output() countRadioButtonSelectionChanged: EventEmitter[string] = new EventEmitter[string](); // This method raises the custom event. We will bind this // method to the change event of all the 3 radio buttons onRadioButtonSelectionChange() { this.countRadioButtonSelectionChanged.emit(this.selectedRadioButtonValue); } } The following are the changes required in the view template of EmployeeCountComponent i.e employeeCount.component.html. Notice we have made 3 changes on each radio button 1. value attribute is set to (All, Male or Female) 2. Implemented 2 way data-binding using the ngModel directive. Notice ngModel is bound to selectedRadioButtonValue property in the component class. This 2 way data-binding ensures whenever the radio button selection changes, the selectedRadioButtonValue property is updated with the value of the selected radio button. 3. onRadioButtonSelectionChange() method is binded to "change" event of the radio button. So this means whenever, the selection of the radio button changes, onRadioButtonSelectionChange() method raises the custom event "countRadioButtonSelectionChanged". We defined this custom event using Angular EventEmitter class. [span class="radioClass"]Show : [/span] [input name='options' type='radio' value="All" [(ngModel)]="selectedRadioButtonValue" (change)="onRadioButtonSelectionChange()"] [span class="radioClass"]{{'All(' + all + ')'}}[/span] [input name="options" type="radio" value="Male" [(ngModel)]="selectedRadioButtonValue" (change)="onRadioButtonSelectionChange()"] [span class="radioClass"]{{"Male(" + male + ")"}}[/span] [input name="options" type="radio" value="Female" [(ngModel)]="selectedRadioButtonValue" (change)="onRadioButtonSelectionChange()"] [span class="radioClass"]{{"Female(" + female + ")"}}[/span]

Part 3.9 Practice questions on Minimal set of Functional Dependency | Canonical cover Irreducible
Thank you friends for watching the video. Please Like the video if it has helped you in any way & do subscribe to the channel. This video explains the questions based on the concept of canonical set of functional dependencies, also known as irreducible set of functional dependencies in DBMS. Questions related to Irreducible set of functional dependency like Canonical cover of functional dependency, Importance of minimal cover of functional dependency in Normalization, redundancy in functional dependency, Step by step explanation to find the minimal cover of functional dependency, How to find redundant functional dependency, Trick to find minimal cover of functional dependency fast, Decomposing functional dependency, Problem solving based on of canonical cover of functional dependencies in DBMS ,Minimal cover of Functional dependency questions for Gate, UGC-NET, PSU’s and university exams, Solved examples of minimal cover set of functional dependency, Previous year gate questions of minimal cover of functional dependency are discussed. Notes: Minimal cover- It means to eliminate any kind of redundancy from a FD set. A canonical cover of a set of functional dependencies F is a simplified set of functional dependencies that has the same closure as the original set F. There may be any following type of redundancy in the set of functional dependencies:- a. Complete production may be Redundant. b. One or more than one attributes may be redundant on right hand side of a production. c. One or more than one attributes may be redundant on Left hand side of a production. Procedure to find MINIMAL COVER- i) Use decomposition rule wherever applicable so that RHS of a production/FD contains only single attribute. ii) Remove extraneous attribute on LHS of a production by finding the closure for every possible subset, if in any case the closure is same it means remaining attributes are redundant. iii) For every production find the closure value of LHS of production keeping the production in a set, and next time ignoring the production to be in a set. iv) If both closure sets matches ,it means the production is redundant.

Two way data binding in angular 2
Text version of the video http://csharp-video-tutorials.blogspot.com/2017/07/two-way-data-binding-in-angular-2.html Slides http://csharp-video-tutorials.blogspot.com/2017/07/two-way-data-binding-in-angular-2_10.html Angular 2 Tutorial playlist https://www.youtube.com/playlist?list=PL6n9fhu94yhWqGD8BuKuX-VTKqlNBj-m6 Angular 2 Text articles and slides http://csharp-video-tutorials.blogspot.com/2017/06/angular-2-tutorial-for-beginners_12.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists In this video we will discuss Two way Data Binding in Angular 2. Consider the following code in app.component.ts import { Component } from '@angular/core'; @Component({ selector: 'my-app', template: ` Name : [input [value]='name'] [br] You entered : {{name}} ` }) export class AppComponent { name: string = 'Tom'; } [input [value]='name'] : Binds component class "name" property to the input element’s value property You entered : {{name}} : Interpolation displays the value we have in "name" property on the web page At the moment when we change the value in the textbox, that changed value is not reflected in the browser. One way to achieve this is by binding to the input event of the input control as shown below. Name : [input [value]='name' (input)='name = $event.target.value'] [br] You entered : {{name}} At this point, as we type in the textbox, the changed value is displayed on the page. So let's understand what is happening here. Conside this code Name : [input [value]='name' (input)='name = $event.target.value'] [br] You entered : {{name}} [value]='name' : This property binding flows data from the component class to element property (input)='name = $event.target.value' : This event binding flows data in the opposite direction i.e from the element to component class property "name" $event - Is exposed by angular event binding, and contains the event data. To retrieve the value from the input element use - $event.target.value. name = $event.target.value - This expression updates the value in the name property in the component class You entered : {{name}} - This interpolation expression will then display the value on the web page. So in short two-way data binding in Angular is a combination of both Property Binding and Event Binding. To save a few keystrokes and simplify two-way data binding angular has provided ngModel directive. So with ngModel directive we can rewrite the follwing line of code Name : [input [value]='name' (input)='name = $event.target.value'] Like this : Name : [input [(ngModel)]='name'] At this point if you view the page in the browser, you will get the following error Template parse errors: Can't bind to 'ngModel' since it isn't a known property of 'input' This is because ngModel directive is, in an Angular system module called FormsModule. For us to be able to use ngModel directive in our root module - AppModule, we will have to import FormsModule first. Here are the steps to import FormsModule into our AppModule 1. Open app.module.ts file 2. Include the following import statement in it import { FormsModule } from '@angular/forms'; 3. Also, include FormsModule in the 'imports' array of @NgModule imports: [BrowserModule, FormsModule] With these changes, reload the web page and it works as expected. So here is the syntax for using two-way data binding in Angular [input [(ngModel)]='name'] The square brackets on the outside are for property binding The parentheses on the inside are for event binding To easily remember this syntax, compare it to a banana in a box [()]

How to Specify Material Properties with Functions in COMSOL Multiphysics
You can define an Analytic, Interpolation, or Piecewise Function to describe any material property in COMSOL Multiphysics. Defining a function for a material enables the software to approximate the value of the material property through the duration of your simulation. Interpolation Functions are used to fit an expression to data defined at discrete points, such as measurements. Enter the data manually or import it from a file. Next, choose how the function behaves both between and outside of your data points. Analytic Functions are used to implement a variable-dependency to a material, like a temperature and/or pressure-dependent property. You can enter your equation and then specify the arguments within the expression. Piecewise Functions are used to add a function that has different definitions on different intervals. For each interval of values, you can specify a Start and End value as well as the function applicable to that range of values.

Angular component lifecycle hooks
Text version of the video http://csharp-video-tutorials.blogspot.com/2017/08/angular-component-lifecycle-hooks.html Slides http://csharp-video-tutorials.blogspot.com/2017/08/angular-component-lifecycle-hooks_1.html Angular 2 Tutorial playlist https://www.youtube.com/playlist?list=PL6n9fhu94yhWqGD8BuKuX-VTKqlNBj-m6 Angular 2 Text articles and slides http://csharp-video-tutorials.blogspot.com/2017/06/angular-2-tutorial-for-beginners_12.html All Dot Net and SQL Server Tutorials in English https://www.youtube.com/user/kudvenkat/playlists?view=1&sort=dd All Dot Net and SQL Server Tutorials in Arabic https://www.youtube.com/c/KudvenkatArabic/playlists In this video we will discuss Angular component lifecycle hooks. A component has a lifecycle managed by Angular. Angular 1. Creates the component 2. Renders the component 3. Creates and renders the component children 4. Checks when the component data-bound properties change, and 5. Destroys the component before removing it from the DOM To tap into and react when these life cycle events occur, angular offers several lifecycle hooks The 3 most commonly used hooks are ngOnChanges - Executes, every time the value of an input property changes. The hook method receives a SimpleChanges object containing current and previous property values. This is called before ngOnInit. ngOnInit - Executes after the constructor and after ngOnChange hook for the first time. It is most commonly used for component initialisation and retrieving data from a database. ngOnDestroy - Executes just before angular destroys the component and generally used for performing cleanup. There are 3 simple steps to use the Life Cycle Hooks Step 1 : Import the Life Cycle Hook interface. For example, to use ngOnInit() life cycle hook, import OnInit interface. import { OnInit } from '@angular/core'; Step 2 : Make the component class implement the Life Cycle Hook interface, using the implements keyword as shown below. This step is optional, but good to have so you will get editor support and flags errors at compile time if you incorrectly implement the interface method or make any typographical errors. export class SimpleComponent implements OnInit { } Step 3 : Write the implementation code for the life cycle interface method. Each interface has a single hook method whose name is the interface name prefixed with ng. ngOnInit() { console.log('OnInit Life Cycle Hook'); } Let's understand ngOnChanges life cycle hook with a simple example. Here is what we want to do. As soon as the user starts typing into the text box, we want to capture the current and previous value and log it to the browser console. We can very easily achieve this by using the ngOnChanges life cycle hook. ngOnChanges, is called every time the value of an input property of a component changes. So first let's create a SimpleComponent with an input property as shown below. We will continue with the example we worked with in our previous video. Add a new folder in the App folder and name it Others. Add a new TypeScript file to this folder and name it - simple.component.ts. Copy and paste the following code which is commented and self explanatory. // Step 1 : Import OnChanges and SimpleChanges import { Component, Input, OnChanges, SimpleChanges } from '@angular/core'; // The selector "simple" will be used as the directive // where we want to use this component. Notice we are // also using the simpleInput property with interpolation // to display the value it receives from the parent // component @Component({ selector: 'simple', template: `You entered : {{simpleInput}}` }) // Step 2 : Implement OnChanges Life Cycle Hook interface export class SimpleComponent implements OnChanges { // Input property. As and when this property changes // ngOnChanges life cycle hook method is called @Input() simpleInput: string; // Step 3 : Implementation for the hook method // This code logs the current and previous value // to the console. ngOnChanges(changes: SimpleChanges) { for (let propertyName in changes) { let change = changes[propertyName]; let current = JSON.stringify(change.currentValue); let previous = JSON.stringify(change.previousValue); console.log(propertyName + ': currentValue = ' + current + ', previousValue = ' + previous); // The above line can be rewritten using // placeholder syntax as shown below // console.log(`${propertyName}: currentValue // = ${current }, previousValue = ${previous }`); } } }

Call child component methods and properties using template reference variable
In this video we will discuss how to call child component methods and properties from parent component. One way to do this is by using output properties. We discussed output properties in Part 37 of Angular CRUD tutorial. Another way, to pass data from the child component to the parent component is by using a template reference variable. Let us understand this with an example. We want to do the same thing that we did with Output properties in Part 37. The child component DisplayEmployeeComponent is responsible for displaying each Employee details in a Bootstrap Panel. Here is what we want to do. When we click on any of the employee panel we want to display that employee name and gender. So we need to pass employee name and gender from the child component (DisplayEmployeeComponent) to parent component (ListEmployeesComponent). Here is the child component class. Notice the class has employee property and getNameAndGender() method. We will be calling both of these from the parent component (ListEmployeesComponent) using a template reference variable. export class DisplayEmployeeComponent { @Input() employee: Employee; getNameAndGender(): string { return this.employee.name + ' ' + this.employee.gender; } } Code in Parent Component View Template (list-employees.component.html) <h1 #h1Variable></h1> <div *ngFor="let employee of employees"> <div (click)="h1Variable.innerHTML = childComponent.getNameAndGender()"> <app-employee-display [employee]="employee" #childComponent> </app-employee-display> </div> </div> Code Explanation : #childComponent is the template reference variable to the child component. Using this template variable we can call child component public property (employee) and method (getNameAndGender()) <div (click)="handleClick(childComponent.getNameAndGender())">. Using the template reference variable we are calling the child component method getNameAndGender(). The value this method returns is assigned to the innerHTML property of the <h1> element. #h1Variable is the template reference variable for <h1> element. At this point when you click on an employee panel, you will see that employee's name and gender displayed by the <h1> element. Calling the child component property using template reference variable : Notice in the example below, we are calling the child component public property employee using the template reference variable childComponent. <h1 #h1Variable></h1> <div *ngFor="let employee of employees"> <div (click)="h1Variable.innerHTML = childComponent.employee.name + ' ' + childComponent.employee.gender"> <app-employee-display [employee]="employee" #childComponent> </app-employee-display> </div> </div> Even now, when you click on an employee panel, you will see that employee's name and gender displayed by the <h1> element exactly the same way as before. Summary : There are 2 ways to pass data from Child Component to Parent Component 1. Output Properties 2. Template Reference Variable With Output properties there are several moving parts. In the child component we need to create a custom event. Raise the custom event. From the parent component bind to the child component event and handle it. With the template reference variable approach, we do not have so many moving parts. We just declare a template reference variable and use it to call the child component public properties and methods.

You can get the source code of this sample in the GitHub repository: https://github.com/cefsharptutorials/cefsharptutorials/tree/master/CefSharpTutorials/RemoteDebugging About CefSharp: https://cefsharp.github.io/ Previous tutorials: CefSharp Basics: Display an HTML5/CSS3 Webpage - https://www.youtube.com/watch?v=gphqZTCWoZE&list=PLtnonz7r7xrqI7OS0eWwc4lrwV5zqI4r3 URL Navigation Using CefSharp - https://www.youtube.com/watch?v=NTlErRwyYRA&index=2&list=PLtnonz7r7xrqI7OS0eWwc4lrwV5zqI4r3 Executing JavaScript from the .NET Side Using CefSharp - https://www.youtube.com/watch?v=Gmdx0cGnNsE&list=PLtnonz7r7xrqI7OS0eWwc4lrwV5zqI4r3&index=3 Injecting a .NET Object into JavaScript Using СefSharp - https://www.youtube.com/watch?v=T10Xfe4bepo&list=PLtnonz7r7xrqI7OS0eWwc4lrwV5zqI4r3&index=4 Transcript: 00:01 Remote debugging using СefSharp 00:06 Create and configure a WPF solution with CefSharp 00:12 Create a project 00:13 Add the CefSharp.Wpf NuGet package and create the x64 or x86 configuration 00:20 You can find detailed instructions in our previous tutorials. (Check out the links under this video) 00:26 Mark Up the Main Window 00:28 Define the name of the root grid 00:30 We need to insert two browser instances into the main window so let's create two columns in the Root Grid 00:44 Implement the Main Window behaviour 00:46 Create two fields in the MainWindow class for both left and right browsers 00:57 After the window initialization create a new instance of the ‘CefSettings’ class 01:09 Then set the value of the ‘RemoteDebuggingPort’ property to 8088 01:13 Call the ‘Cef.Initialize’ method and pass the created settings instance as its argument 01:19 Initialize the ‘leftBrowser’ field with the new instance of the ChromiumWebBrowser 01:24 Add this field to the RootGrid 01:30 Set the grid column index of the browser using the ‘Grid.ColumnIndex’ dependency property 01:42 Then repeat the previous three steps for the ‘rightBrowser’ field but change the value of the grid column index property 01:59 Create the ‘FrameLoadEnd’ event handler for the left browser 02:04 Set the ‘Address’ property value for the left browser 02:16 Inside the ‘FrameLoadEnd’ event handler set the Address property of the right browser to ‘localhost:8088’. 02:23 You need to use the dispatcher because the ‘FrameLoadEnd’ event occurs inside the non-UI thread. 02:35 Build and launch #Debugging #CefSharp #EmbeddedBrowsers

61.Loading properties files as part of the application  configuration
In this video you will learn how Spring load properties files as part of the application configuration, for use internally. The properties can be referenced within spring configuration files using ant-style placeholders e.g. ${db.url},${db.username},${db.password} etc. Below is the GitHub link to download source Code: https://github.com/kishanjavatrainer/SpringWithJDBCProject.git

Further, it reduces the memory footprint during the startup of the program. Reducing the memory print will help faster loading of the application. Non-Lazy or Eager Loading : Eager loading is nothing but to initialize the required object before it’s being accessed. Which means, we instantiate the object and keep it ready and use it when we need it. This type of initialization is used in lower memory footprints. Also, in eager loading, the common language runtime takes care of the variable initialization and its thread safety. Hence, we don’t need to write any explicit coding for thread safety. Singleton with Lazy keyword (.NET 4.0) : Lazy keyword provides support for lazy initialization. In order to make a property as lazy, we need to pass the type of object to the lazy keyword which is being lazily initialized. By default, Lazy[T] objects are thread-safe. In multi-threaded scenarios, the first thread which tries to access the Value property of the lazy object will take care of thread safety when multiple threads are trying to access the Get Instance at the same time. Therefore, it does not matter which thread initializes the object or if there are any thread race conditions that are trying to access this property.
