To compute the GridView Sum in asp.net let’s take a simple example of SQL Database table. For GridView sum in ASP.net you can use the Northwind SQL database table to test the source code given in this tutorial. Here we will use products SQL table of Northwind database. In this tutorial we will compute the sum of units in stock of each product in the specified category.
Now you are ready to connect this SQL table with ASP.net web page to display the records in SQL table. But still you need a control to display the records in tabular format so that you could show the sum of column exactly below the Units in Stock column of GridView control.
HTML code with Auto Formatted GridView in ASP.Net Web Page
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" CellPadding="2" ShowFooter="true">
<Columns>
<asp:TemplateField HeaderText="Product Name" HeaderStyle-Width="200px">
<ItemTemplate> <%# DataBinder.Eval(Container.DataItem, "ProductName") %>
</ItemTemplate>
<FooterTemplate>
<asp:Label ID="Label1" runat="server" Text="Total Units">
</asp:Label>
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Units In Stock">
<ItemTemplate>
<%# DataBinder.Eval(Container.DataItem, "UnitsInStock") %></ItemTemplate>
<FooterTemplate><asp:Label ID="Label2" runat="server"></asp:Label></FooterTemplate></asp:TemplateField></Columns><HeaderStyle HorizontalAlign="Left" /><FooterStyle BackColor="#cccccc" Font-Bold="true" /></asp:GridView>
In the above HTML code of GridView control of ASP.Net 2.0 you can notice that we have created two columns of GridView using ItemTemplate of TemplateField to display the Product Name and Units in stock Columns of Products Table. In both TemplateField columns we also added FooterTemplate sections having Label controls. Under product name column Text property of Label control has been set to "Total Unit". For the Label control placed inside the FooterTemplate of second TemplateField displaying the Units In Stock column we will set its Text property dynamically after computing the sum of associated column.
C# Sample code to Compute the Sum of Column in GridView control of ASP.Net
SqlCommand mySqlCommand = new SqlCommand("select productid, productname, unitsinstock from products where categoryid = @categoryid", mySQLconnection);
SqlDataAdapter mySqlAdapter = new SqlDataAdapter(mySqlCommand);
mySqlCommand.Parameters.Add("@categoryid", SqlDbType.Int).Value = 1;
DataSet myDataSet = new DataSet();
mySqlAdapter.Fill(myDataSet);
GridView1.DataSource = myDataSet;GridView1.DataBind();((Label)GridView1.FooterRow.Cells[1].FindControl("Label2")).Text = myDataSet.Tables[0].Compute("sum(unitsinstock)", "").ToString();
In the above C# code Compute function is used that returns the passed expression for all the rows of a table in a dataset. According to above code, it will return the sum of units in stock for each product in the specified category.
Compute function of DataTable in ASP.Net
Compute function takes 2 parameters:
1.String Expression:
Expression as a agregate function of sql.
2.String Filter:
Filter criteria to filter the retrived rows.
E.g.:
((Label)GridView1.FooterRow.Cells[1].FindControl("Label2")).Text = myDataSet.Tables[0].Compute("sum(unitsinstock)", "categoryid=1").ToString();
Above C# example code line shows that you can also specify the string Filter as a second parameter of Compute function to evaluate the result according to to specified string expression as aggregate function as a first parameter.

This tutorial will show you how to display data using the .NET GridView Control, stored procedures, ASP.NET 2.0 and C#.NET
Querying an SQL database with stored procedures using C# .NET is easy to do.
First, you will need to import the System.Data.SqlClient namespace.
The System.Data.SqlClient namespace contains the SqlCommand and SqlConnection classes that we need in order to connect to our database and to send an SQL command to it.
using System.Data.SqlClient;
We'll put our code in the Page_Load() event.
When the Page_Load() event fires, a new SqlCommand object is instantiated with our connection string and our stored procedure name. We add the parameters needed for the stored procedure by using our SqlCommand object's Parameters.Add() method.
Afterwards, we will attempt to connect using the Open() method of our cmd.Connection object. Once it is connected we will attempt to execute the stored procedure we specified earlier (in this example CustOrderHist stored procedure in the Northwind db).
If all goes well, we will have the results of our SQL query assigned to the gvwExample's DataSource property. Now all we have to do is call the DataBind() method of our gvwExample to bind the data to the control. The data is now ready to be displayed.
protected void Page_Load(object sender, EventArgs e)
{
try
{
SqlCommand cmd = new SqlCommand("CustOrderHist", new SqlConnection("Server=localhost;Database=Northwind;Trusted_Connection=True;"));
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("CustomerID", txtCustID.Text);
cmd.Connection.Open();
gvwExample.DataSource = cmd.ExecuteReader();
gvwExample.DataBind();
cmd.Connection.Close();
cmd.Connection.Dispose();
}
catch (Exception ex)
{
lblStatus.Text = ex.Message;
}
}
We have to add a few tags on the front end of the .aspx page to place where we want the GridView control to display its bound data. We also specify what part of the data from the data set we would like to display. The front end .aspx page looks something like this:
<table width="600" border="0" align="center" cellpadding="5" cellspacing="1" bgcolor="#cccccc">
<tr>
<td width="100" align="right" bgcolor="#eeeeee" class="header1"> Customer Data Using Stored Procedures:</td>
<td align="center" bgcolor="#FFFFFF">
<asp:GridView ID="gvwExample" runat="server" AutoGenerateColumns="False" CssClass="basix" >
<columns>
<asp:BoundField DataField="ProductName" HeaderText="Product Name" />
<asp:BoundField DataField="Total" HeaderText="Total" />
</columns>
</asp:GridView>
<br />
Customer ID:
<asp:TextBox ID="txtCustID" runat="server" Width="42px">ALFKI</asp:TextBox>
Order ID:<asp:TextBox ID="txtOrderID" runat="server" Width="43px">10256</asp:TextBox><br />
<asp:Button ID="btnSubmit" runat="server" Text="Go" />
<br />
<asp:label ID="lblStatus" runat="server"></asp:label></td>
</tr>
</table>
The flow for the code behind page is as follows.
using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;

{
SqlCommand cmd = new SqlCommand("CustOrderHist", new SqlConnection("Server=localhost;Database=Northwind;Trusted_Connection=True;"));
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add("CustomerID", txtCustID.Text);
cmd.Connection.Open();
gvwExample.DataSource = cmd.ExecuteReader();
gvwExample.DataBind();
cmd.Connection.Close();
cmd.Connection.Dispose();
}
catch (Exception ex)

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 . 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. These properties make JSON an ideal data-interchange language.
JSON is built on two structures:
* A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array.
* An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence.
These are universal data structures. Virtually all modern programming languages support them in one form or another. It makes sense that a data format that is interchangable with programming languages also be based on these structures.
In JSON, they take on these forms:
An object is an unordered set of name/value pairs. An object begins with { (left brace) and ends with } (right brace). Each name is followed by : (colon) and the name/value pairs are separated by , (comma).
An array is an ordered collection of values. An array begins with [ (left bracket) and ends with ] (right bracket). Values are separated by , (comma).
A value can be a string in double quotes, or a number, or true or false or null, or an object or an array. These structures can be nested.
A string is a collection of zero or more Unicode characters, wrapped in double quotes, using backslash escapes. A character is represented as a single character string. A string is very much like a C or Java string.
A number is very much like a C or Java number, except that the octal and hexadecimal formats are not used.
Whitespace can be inserted between any pair of tokens. Excepting a few encoding details, that completely describes the language.
Example :
object
{}
{ members }

tag:-JSON with PHP Introduction
The crypt() Function
In PHP we can use the crypt () function to create one way encryption. This means that the data is encrypted but cannot easily be decrypted.
When a user chooses their password, the password is then encrypted and the encrypted version of this password is saved. The next time the user goes to login, their password is encrypted again and then checked against the already saved (encrypted) version to see if they are the same. This way if the data is intercepted, they only ever see the encrypted version.
The crypt function is phrased as: crypt ( input_string, salt)
In this case input_string is the string you would like to encrypt (your password for example,) and salt is an optional parameter that influences how the encryption will work. PHP by default uses a two character DES salt string. If your system standard is MD5, a 12-character salt string is used.
The following are the four types of salt that work with all crypt () functions.
CRYPT_STD_DES - Standard DES-based encryption with a two character salt
CRYPT_EXT_DES - Extended DES-based encryption with a nine character salt
CRYPT_MD5 - MD5 encryption with a twelve character salt starting with $1$
CRYPT_BLOWFISH - Blowfish encryption with a sixteen character salt starting with $2$ or $2a$
when we use crypt ()
<?php $password = crypt('mypassword'); print $password . %u201C is the encrypted version of mypassword%u201D; ?>
This will output the encrypted version of ‘mypassword’ for you to see. Now let’s try it using different types of salt.
<?
php $password = crypt('mypassword' , 'd4');
print $password . " is the CRYPT_STD_DES version of mypassword<br>";
$password = crypt('mypassword' , 'k783d.y1g');
print $password . " is the CRYPT_EXT_DES version of mypassword<br>";
$password = crypt('mypassword' , '$1$d4juhy6d$');
print $password . " is the CRYPT_MD5 version of mypassword<br>";
$password = crypt('mypassword' , '$2a$07$kiuhgfslerd...........$');
print $password . " is the CRYPT_BLOWFISH version of mypassword<br>";
?>
This will output something like this:
d4/qPbCcJ5tD. is the CRYPT_STD_DES version of mypassword
k7xEagYCDPPSc is the CRYPT_EXT_DES version of mypassword
$1$d4juhy6d$a.jIPYnvne1FWF2V6mGQR0 is the CRYPT_MD5 version of mypassword
$2a$07$kiuhgfslerd...........6k0kSI76CqJ/RWGnSp9MWRDF91gJZfW is the CRYPT_BLOWFISH version of mypassword

How can Read/Write in App.Config File using C#.Net
1.Create app.config File
<add key="EMConnectionstring" value="Provider=Microsoft.Jet.OLEDB.4.0;Persist Security Info=False;Data Source = D:EventManagementSystem.mdb" />
2. Add new reference "System.Configure" dll
using System.Configuration;
// Open App.Config of executable
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
//ConfigurationSettings.AppSettings.
string value = string.Empty;
foreach (string key in ConfigurationManager.AppSettings)
{
value = ConfigurationManager.AppSettings[key].ToString();
}
config.AppSettings.Settings.Add("EMConnectionstring", value);
// Save the changes in App.config file.
config.Save(ConfigurationSaveMode.Modified);
// Force a reload of a changed section.
ConfigurationManager.RefreshSection("appSettings");
Different types of Operators using in PHP they are Arithemtic Operators,Assignment Operators,Comparison Operators,Increment/decrement Operators,Logic Operators,String Operators
Arthimetic Operators
Example Name Result
-$a Negation Opposite of $a.
$a - $b Subtraction Difference of $a and $b.
$a + $b Addition Sum of $a and $b.
$a / $b Division Quotient of $a and $b.
$a % $b Modulus Remainder of $a divided by $b.
$a * $b Multiplication Product of $a and $b.
Assignment Operators
The basic assignment operator is "=". Your first inclination might be to think of this as "equal to". Don't. It really means that the left operand gets set to the value of the expression on the rights (that is, "gets set to").
Example :
<?php
$a = ($b = 4) 5; // $a is equal to 9 now, and $b has
been set to 4.
?>
Comparison Operators
PHP using Comparison operators in C,C++,java except "===" operator
Example Name Result
$a == $b Equal TRUE if $a is equal to $b.
$a === $b Identical TRUE if $a is equal to $b, and they are of the same type.
$a != $b Not equal TRUE if $a is not equal to $b.
$a <> $b Not equal TRUE if $a is not equal to $b.
$a !== $b Not identical TRUE if $a is not equal to $b, or they are not of the same type.
$a < $b Less than TRUE if $a is strictly less than $b. $a >= $b Greater than or equal to TRUE if $a is greater than or equal to $b.
Increment and Decrement Operator
++,-- operators
Example Name Effect
++$a Pre-increment Increments $a by one, then returns $a.
$a++ Post-increment Returns $a, then increments $a by one
--$a Pre-decrement Decrements $a by one, then returns $a.
$a-- Post-decrement Returns $a, then decrements $a by one.
Example:
<?php echo "<h3>Postincrement</h3>";
$a = 5;
echo "Should be 5: " . $a . "<br />\n"; echo "Should be 6: " . $a . "<br />\n";
echo "<h3>Preincrement</h3>";
$a = 5;
echo "Should be 6: " . $a . "<br />\n"; echo "Should be 6: " . $a . "<br />\n";
echo "<h3>Postdecrement</h3>";
$a = 5;
echo "Should be 5: " . $a-- . "<br />\n";
echo "Should be 4: " . $a . "<br />\n";
echo "<h3>Predecrement</h3>";
$a = 5;
echo "Should be 4: " . --$a . "<br />\n";
echo "Should be 4: " . $a . "<br />\n";
?>
Arithemetic Operator on Character Variable
Example :
<?php
$i = 'W';
for ($n=0; $n<6; $n )
{
echo $i . "\n";
}
?>
The above example will output:
X Y Z AA AB AC
String Operators
There are two string operators. The first is the concatenation operator ('.'), which returns the concatenation of its right and left arguments. The second is the concatenating assignment operator ('.='), which appends the argument on the right side to the argument on the left side.
Example :
<?php
$a = "Hello ";
$b = $a . "World!"; // now $b contains "Hello World!" $a = "Hello ";
$a .= "World!"; // now $a contains "Hello World!"
?>
Logical Operators
Example Name Result
$a and $b And TRUE if both $a and $b are TRUE.
$a or $b Or TRUE if either $a or $b is TRUE.
$a xor $b Xor TRUE if either $a or $b is TRUE, but not both.
! $a Not TRUE if $a is not TRUE.
$a || $b Or TRUE if either $a or $b is TRUE
$a && $b And TRUE if both $a and $b are TRUE.

Constants in PHP : using define()-function
Constant
A constant is an identifier (name) for a simple value. As the name suggests, that value cannot change during the execution of the script . A constant is case-sensitive by default. By convention, constant identifiers are always uppercase.
How can declare Constant ?
You can define a constant by using the define()-function. Once a constant is defined, it can never be changed or undefined.
<?php // Valid constant names define("FOO", "something"); define("FOO2", "something else"); define("FOO_BAR", "something more"); // Invalid constant names define("2FOO", "something");
define("CONSTANT", "Hello world.");
echo CONSTANT; // outputs "Hello world." ?>
Important things ..
- Constants do not have a dollar sign ($) before them;
- Constants may only be defined using the define() function.
- Constants may only evaluate to scalar values (integer,float,boolean,strings).

tag:- Create PDF Files on fly in C#
If you've got a Stream in .NET - whether its fetched from a HttpWebRequest or read from another file - you can easily save this stream to another file using the following code.
// readStream is the stream you need to read
// writeStream is the stream you want to write to
private void ReadWriteStream(Stream readStream, Stream writeStream)
{
int Length = 256;
Byte [] buffer = new Byte[Length];
int bytesRead = readStream.Read(buffer,0,Length);
// write the required bytes
while( bytesRead > 0 )
{
writeStream.Write(buffer,0,bytesRead);
bytesRead = readStream.Read(buffer,0,Length);
}
readStream.Close();
writeStream.Close();
}
To call this method, just do something like this:
string saveTo = "some path to save"
// create a write stream
FileStream writeStream = new FileStream(saveTo, FileMode.Create, FileAccess.Write);
// write to the stream
ReadWriteStream(readStream,writeStream);

Media Player in Internet Explorer and Mozilla FireFox
IE has interesting dynsrc parameter for the tag. The code can look like this:
<img dynsrc="MyVideo.avi" />
More compatible solution is to use <embed> tag. This solution is better since it is supported by different web browsers (notice that it is not recommended by W3C as standard HTML). Code can look like this:
<embed src="MyVideo.avi"></embed>
Instead of using of <embed> tag, W3C recommends <object> tag. Here is the code to display WMV video file with <object> HTML tag:
<object height="320px" width="240px" type ="video/x-ms-wmv">
<param name="src" value="http://localhost/MyMovie.wmv" />
</object>
Display video with Media Player active X control in Internet Explorer
More flexible way to show video on your ASP.NET web site is to use Windows Media Player active X control. Media player is probalbly already used by most of your site visitors. So they feel familiar with it. Also, Media Player supports many different file types. This control in Internet Explorer web browser is presented with <object> HTML tag with code like this:

As you can see, Windows Media Player control has many properties. You are not required to set it all. If some property is not used, then control uses its default value. Of course, some property like FileName we must use if we want to play anything.
Custom ASP.NET Media Player Control
Placing static HTML code for Media Player control will not be very efficient method. It is much better to make custom ASP.NET server control which will render correct HTML code depending of property values. This custom control can be used easily by ASP.NET web application, to show play lists, to remember user preferences etc.Control will automatically detect web browser type and render appropriate HTML code.

In PHP three types of strings are using single quoted,double quoted,heredoc
A string literal can be specified in four different ways:
- single quoted
- double quoted
- heredoc
Single quoted
The simplest way to specify a string is to enclose it in single quotes (the character ').
echo 'this is a simple string'; echo 'You can also have embedded newlines in strings this way as it is okay to do'; // Outputs: Arnold once said: "I'll be back" echo 'Arnold once said: "I\'ll be back"';
<?php
echo 'this is a simple string';
echo 'You can also have embedded newlines in strings this way as it is okay to do';
// Outputs: Arnold once said: "I'll be back" echo 'Arnold once said: "I\'ll be back"';
?>
heredoc
<?php
echo <<<EOT My name is "$name".
I am printing some EOT;?>
A third way to delimit strings is the heredoc syntax: <<<. After this operator, an identifier is provided, then a newline. The string itself follows, and then the same identifier again to close the quotation. The closing identifier must begin in the first column of the line. Also, the identifier must follow the same naming rules as any other label in PHP: it must contain only alphanumeric characters and underscores, and must start with a non-digit character or underscore

When a variable is set it can be used over and over again in your script
All variables in PHP start with a $ sign symbol.
The correct way of setting a variable in PHP:
Example :

PHP is a powerful server-side scripting language for creating dynamic and interactive websites. PHP is the widely-used, free, and efficient alternative to competitors such as Microsoft's ASP. PHP is perfectly suited for Web development and can be embedded directly into the HTML code. The PHP syntax is very similar to Perl and C. PHP is often used together with Apache (web server) on various operating systems.
