HTML02: Syntax

A HTML source code consist of tags. THe syntax of a tag is

<tag>the content of the tag</tag>

a tag is written inside a pair of angle brackets, the opening angle bracket '<' and the closing angle bracket '>'. the tag on the front is called start tag. The tag at the back is called end tag. End tag has the forward slash. Anything written in between the start tag and end tag belongs to the specified tag.

the content of the tag may have multiple lines, so very often we would see

<tag>
  the content of the tag
  ...
</tag>

Common tags are <p> which denotes paragraph in a page, <h1> which denotes heading or <a> link to other pages or websites.

Following is a common structure of a HTML source code, this also can be used as template for all other source codes.

<html>

  <head>
    <title>Title in tab</title>
  </head>

  <body>
    <h1>Page title</h1>

    <p>
      A paragraph in this page
    </p>
  </body>

</html>


the entire source code is enclosed in side of <html> tag. Inside the <html> tag there are two major parts which: <head> and <body>. All the visible elements of the page is written in the <body> tag.

this will produce following output in a browser

Page title

A paragraph in this page...


the <h1> tag display the text in largest heading font size. Next the paragraph is enclosed in <p>.

The link opens a new page or web site when clicked. The URL or address of the destination the link heads to is written on href attribute. Each tag has attribute that allow us to specify how we want the tag to behave.

<html>
  <body>
    <a href = "www.google.com">Link to google</a>
  </body>
</html>

this will produce following output:
 

A link will be displayed in blue color font with an underline, cursor changes to link pointer when the mouse cursor hovers over the link. When the link is clicked. browser will immediately opens the url given in the href attribute.

Drawing Simple Pie Chart

Image
To draw pie chart with 5 sectors. The program calculates the total of all the input given by user and find the angle in degrees to draw each sectors. When the program first loads, chart based on default values is painted by the program. User can edit the values in the text field and presses draw button to redraw the chart. Each time the draw button is pressed, new set of angle is calculated and repainted. I have attached the the sources for this program. It is simple and needs upgrades. Pie.java This class executed the program and initializes the components JTextField and JPanel to draw the chart. package coolApp.graphics; import java.awt.*; import java.awt.event.*; import javax.swing.*; public class Pie { JTextField a,b,c,d,e; JButton btnDraw; double total; JPanel contentPane; Pie(){ JFrame frame = new JFrame("Pie - CoolApps"); frame.setSize(500,500); contentPane = new JPanel(); contentPane.setLayout(new BorderLayout()); frame

VB.net connecting to SQL Server

Connecting to SQL server 2014 from VB.Net 2017, read values from the database and display the data in windows form. Before begin to write this program, first we need to import SqlClient class. Imports System.Data.SqlClient Step 1 Create a sql connection object. This is to make connection to object. Dim conn As New SqlConnection() Step 2 Set the connection string to the sqlconnection object: conn.ConnectionString = connStr Road block The variable connStr is a connection string. Connection object need connection string to make connection to database. It has information like who providing the database, the name of the database and some security information. Dim connStr As String = "Data Source = ServerInstanceName;Initial Catalog=testDB;Integrated Security=True" Let's break down the connection string into the three main components. Dim provider As String = "ServerInstanceName;" Dim database As String = "Initial Catalog=testDB;" Dim

VB.net

a quick and convenient way to build a window based application. basically there is two main components in VB, the design view where we place the controls on a window form. then we have the code view where we write implementation for each controls on the form. Typically the control implementation or procedures are executed when certain events happens to the controls. Events like mouse click, or value change on text box, form load, form close and so on. After working with programming language like C, C++ and Java, getting use to VB is a bit challenging. its because first of all, VB don't use curly bracket to specify code blocks, and the statements don't end with semicolon. variable declaration for example is written as dim age As Integer in C, C++ and Java it written int age; in VB, variable declaration start with dim keyword, it means dimension and the functions are written as Function addNumber(ByVal num1 As Integer, ByVal num2 As Integer) As Integer addNumber
