The Document Object Model (DOM) as implemented in MSXML provides a programmatic representation of XML documents, fragments, nodes, or node-sets. It also provides an application programming interface for working with XML data.

The following JScript fragments outline the basic process of programming with XML DOM.

var xmlDoc=new ActiveXObject("Microsoft.XMLDOM");

Example:

function loadXML(xmlFilePath)
{
  try //Internet Explorer
  {
    xmlDoc=new ActiveXObject("Microsoft.XMLDOM");
  }
  catch(e)
  {
    try //Firefox, Mozilla, Opera, etc.
    {
      xmlDoc=document.implementation.createDocument("","",null);
    }
    catch(e)
    {
      alert(e.message)
    }
  }
 
  try
  {
    xmlDoc.async=false;
    xmlDoc.load(xmlFilePath); // xmlFilePath - xml file path Ex: test.xml
    return(xmlDoc);
  }
  catch(e)
  {
    alert(e.message)
  }
  return(null);
}

To make the operations such as copy paste using c#,we have to use the Clipboard Class which provides methods to place data on and retrieve data from the system Clipboard.

Example :-

Copy the text from txtCopy to clipboard

 System.Windows.Forms.Clipboard.SetDataObject(txtCopy.Text, true);

Paste the text from clipboard to txtPaste

IDataObject clipData = Clipboard.GetDataObject();
if (clipData.GetDataPresent(DataFormats.Text))
{
txtPaste.Text = clipData.GetData(DataFormats.Text).ToString();
}
else
{
txtPaste.Text = "Could not retrieve data from the clipboard.";
}

We can Convert text to image in c# using System.Drawing namespace.
Here we create a bitmap image and use its Graphics property to convert text passed to image and place the image in a picture box.

private void TextToImage()
{
Color BackColor = Color.White;
String FontName = "Times New Roman";
int FontSize = 25;
int Height = 50;
int Width = 300;
<span style="color: rgb(56, 118, 29);">
//creating bitmap image
<span style="color: rgb(0, 0, 0);">Bitmap </span></span>bitmap = new Bitmap(Width, Height);
 
<span style="color: rgb(56, 118, 29);">//FromImage method creates a new Graphics from the specified Image.</span>
Graphics graphics = Graphics.FromImage(bitmap);
Color color = Color.Gray;
Font font = new Font(FontName, FontSize); 
 
SolidBrush BrushBackColor = new SolidBrush(BackColor);
Pen BorderPen = new Pen(color);
 
Rectangle displayRectangle = new Rectangle(new Point(0, 0), new Size(Width - 1, Height - 1));
<span style="color: rgb(56, 118, 29);">//Drawing a rectangle and filling the background as white
<span style="color: rgb(0, 0, 0);">graphics</span></span>.FillRectangle(BrushBackColor, displayRectangle);
graphics.DrawRectangle(BorderPen, displayRectangle); <span style="color: rgb(56, 118, 29);">
 
//giving the font and color to the string passed</span>
graphics.DrawString(txtEnter.Text,font,Brushes.Red, 0, 0);
pictureBox1.Image = bitmap;

Requirements for JavaBeans:

• there have to be set/get methods specified
• has to have public default constructor (without parameters)
• it should be in a package
• serializable
• get/set methods has to have the same data type!
• bean cannot modify content of a page!

… in general, JavaBean is a standard Class.

It can be used as a simple component in a JSP page.

- get method has to be fast, and it should be plain and simple.

usage in a JSP page:

this is the same as

with JSTL Expression language:

automatically set the bean attributes from names (!important!):
<jsp:setProperty name=”pocetMiest” property=”*”>

Scope can be:

• application - the bean is available in all application, when that’s in more JSP pages, one of them can create it once and other JSP pages can use it. It’s something like a global object for all application.
• session - stored data, just for this session
• request - just for request or forward
• page - smallest scope, just on a page that is called (forwarded or included)

The setInterval() method evaluates a function or an expression repeatedly for the specified number of milliseconds and it returns an interval reference.

Syntax:

variable = setInterval(expression, milliseconds)

or

variable = setInterval(function, milliseconds)

variable holds the interval reference returned by seInterval method.

Example:
Below example display the current time information using setInterval method call the date object.

<html>
<head>
<title> setInterval Method Example </title>
<script language="javascript">

    dt = new Date();
    document.getElementById("lbl").innerText = "Timer : " + dt;
    document.getElementById("btnStart").disabled = true;
    document.getElementById("btnStop").disabled  = false;
  }
 
  function stopSetInt()
  {
    clearInterval(ref)
    document.getElementById("lbl").innerText = "Timer : ";
    document.getElementById("btnStart").disabled = false;
    document.getElementById("btnStop").disabled = true;
  }
</script>
</head>
 
<body onload="startSetInt()">
<label id="lbl" name="lbl"></label>

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition – December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others.
