How to read XML using Javascript?

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);
}

Copy-Paste to and from clipboard using c#

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.";
}

Get Clients IP Address Using ASP.NET

We can get the clients IP address using the Request object's(The Request object retrieves the values that the client browser passed to the server during an HTTP request. ) property Request.ServerVariables Collection.
Request.ServerVariables Collection gets the values of predetermined environment variables.

"REMOTE_ADDR" gets the IP address of the remote host making the request. 

string ipaddr;

ipaddr = HttpContext.Current.Request.ServerVariables["REMOTE_ADDR"];

here the string "ipaddr" stores the clients ip.


List Of other Request.ServerVariables Object

Variable	Description
AUTH_TYPE	The authentication method that the server uses to validate users when they attempt to access a protected script.
CONTENT_LENGTH	The length of the content as given by the client.
CONTENT_TYPE	The data type of the content. Used with queries that have attached information, such as the HTTP queries POST and PUT.
GATEWAY_INTERFACE	The revision of the CGI specification used by the server. Format: CGI/revision.
HTTP_<HeaderName>	The value stored in the header HeaderName. Any header other than those listed in this table must be prefixed by "HTTP_" in order for the ServerVariables collection to retrieve its value. Note: The server interprets any underscore (_) characters in HeaderName as dashes in the actual header. For example if you specify HTTP_MY_HEADER, the server searches for a header sent as MY-HEADER.
LOGON_USER	The Windows NT® account that the user is logged into.
PATH_INFO	Extra path information as given by the client. You can access scripts by using their virtual path and the PATH_INFO server variable. If this information comes from a URL it is decoded by the server before it is passed to the CGI script.
PATH_TRANSLATED	A translated version of PATH_INFO that takes the path and performs any necessary virtual-to-physical mapping.
QUERY_STRING	Query information stored in the string following the question mark (?) in the HTTP request.
REMOTE_ADDR	The IP address of the remote host making the request.
REMOTE_HOST	The name of the host making the request. If the server does not have this information, it will set REMOTE_ADDR and leave this empty.
REQUEST_METHOD	The method used to make the request. For HTTP, this is GET, HEAD, POST, and so on.
SCRIPT_MAP	Gives the base portion of the URL.
SCRIPT_NAME	A virtual path to the script being executed. This is used for self-referencing URLs.
SERVER_NAME	The server's host name, DNS alias, or IP address as it would appear in self-referencing URLs.
SERVER_PORT	The port number to which the request was sent.
SERVER_PORT_SECURE	A string that contains either 0 or 1. If the request is being handled on the secure port, then this will be 1. Otherwise, it will be 0.
SERVER_PROTOCOL	The name and revision of the request information protocol. Format: protocol/revision.
SERVER_SOFTWARE	The name and version of the server software answering the request (and running the gateway). Format: name/version.
URL	Gives the base portion of the URL.

Convert Text to Image using c#

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;

//creating bitmap image
Bitmap bitmap = new Bitmap(Width, Height);

//FromImage method creates a new Graphics from the specified Image.
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));
//Drawing a rectangle and filling the background as white
graphics.FillRectangle(BrushBackColor, displayRectangle);
graphics.DrawRectangle(BorderPen, displayRectangle);

//giving the font and color to the string passed
graphics.DrawString(txtEnter.Text,font,Brushes.Red, 0, 0);
pictureBox1.Image = bitmap;

}
