How to use Tabs in ASP.NET CORE

By
I want to show Components in a tabs , so first of all create few components. In this project we have three components, First View Component  public class AllViewComponent : ViewComponent     {         private readonly UserManager<ApplicationUser> _userManager;         public AllViewComponent(UserManager<ApplicationUser> userManager)         {             _userManager = userManager;         }         public async Task<IViewComponentResult> InvokeAsync()         {             List<StudentViewModel> allUsers = new List<StudentViewModel>();             var items = await _userManager.Users.ToListAsync();             foreach (var item in items)             {                 allUsers.Add(new StudentViewModel {Id=item.Id, EnrollmentNo = item.EnrollmentNo, FatherName = item.FatherName, Name = item.Name, Age = item.Age, Birthdate = item.Birthdate, Address = item.Address, Gender = item.Gender, Email = item.Email });             }

Creating an XML Document

Problem Statement

CyberShoppe, Inc. sells toys and books in the United States. It has three branches in different parts of the country. Currently, the three branches maintain data on their local computer systems. The IT manager at CyberShoppe has identified that a centralized data repository on the products sold through its e-commerce site is required. The data from all branches must be collated and housed in a centralized location. This data must be made available to the accounts and sales sections at the individual branches, regardless of the hardware and software platforms being used at the branches. In addition, the sales personnel require access to the data using palmtops and cellular phones.
The product details of CyberShoppe consists of the product name, a brief description, the price, and the available quantity on hand. A product ID uniquely identified each product.

Solution
To solve the preceding problem, you need to perform the following tasks:

  1. Identify the method to store data in a device-independent format.
  2. Identify the structure of the document in which data is to be stored.
  3. Create an XML document to store the data.
  4. View the XML document in a browser.

Task 1: Identifying the method to store the Data in a Device-Independent Format

In the given problem statement, device ranging from mainframe computers to mobile phones must be able to access information from the data store. For example, the employee of the sales department may need to access product costs using an IBM PC. XML enables different types of devices to access information. Therefore, XML can be used to create the data store in the given scenario.

Task 2 : Identifying the Structure of the Document in Which Data is to be stored.

In the given scenario, PRODUCTDATA has been Identified as the root element. It has one child element, PRODUCT. The PRODUCT element can occur one or more times in the XML document. It acts as the container element for the PRODUCTNAME , DESCRIPTION, PRICE, AND QUANTITY elements. PRODUCTNAME has one attribute called PRODID, which is used to uniquely identify each product. The following figure illustrate the structure of the elements used in the XML document to store the product data.

Structure of the XML Document to Store Product Data

Task 3: Creating an XML Document to Store Data

To create an XML file that contains information about the products sold by CyberShoppe, type the following code in Notepad, and save the file as cyber_products.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<!-- PRODUCTDATA is the root element -->
<PRODUCTDATA>
<PRODUCT PRODID="P001">
<PRODUCTNAME>Barbie Doll</PRODUCTNAME>
<DESCRIPTION>This is a toy for children in the age group of 5-10 years </DESCRIPTION>
<PRICE>12</QUANTITY>
</PRODUCT>
</PRODUCTDATA>

Task 4: Viewing the XML Document in a Browser

To View the XML document in the browser, open the cyber_products.xml file in Internet Explorer . IE provides a default tree view layout for an XML document. You can expand and collapse the tree.

The tree-view structure of the cyber_products.xml document is shown in the following figure

Polynomial representation using Linked List for Data Structure in 'C'

By
Polynomial representation using Linked List The linked list can be used to represent a polynomial of any degree. Simply the information field is changed according to the number of variables used in the polynomial. If a single variable is used in the polynomial the information field of the node contains two parts: one for coefficient of variable and the other for degree of variable. Let us consider an example to represent a polynomial using linked list as follows: Polynomial:      3x 3 -4x 2 +2x-9 Linked List: In the above linked list, the external pointer ‘ROOT’ point to the first node of the linked list. The first node of the linked list contains the information about the variable with the highest degree. The first node points to the next node with next lowest degree of the variable. Representation of a polynomial using the linked list is beneficial when the operations on the polynomial like addition and subtractions are performed. The resulting polynomial can also

Memory representation of Linked List Data Structures in C Language

By
                                 Memory representation of Linked List              In memory the linked list is stored in scattered cells (locations).The memory for each node is allocated dynamically means as and when required. So the Linked List can increase as per the user wish and the size is not fixed, it can vary.                Suppose first node of linked list is allocated with an address 1008. Its graphical representation looks like the figure shown below:       Suppose next node is allocated at an address 506, so the list becomes,   Suppose next node is allocated with an address with an address 10,s the list become, The other way to represent the linked list is as shown below:  In the above representation the data stored in the linked list is “INDIA”, the information part of each node contains one character. The external pointer root points to first node’s address 1005. The link part of the node containing information I contains 1007, the address of
