In real life, I am very lazy and I made it my coding style I always try to make a reusable component that’s my USP for programming which saves my time and extra working both.

Query String PHP

Query string is part of an URI which is use to pass some information in URL. Information pass by a query string can be used by server or client by java script or any server side language. Query string is one most powerful method to pass additional information about web processing application but query string is not recommended to pass sensitive information because query string put flat text which can be read by anyone.

Dynamic Memory allocation C language

Memory is storage unit which every program need for their operation. When you run your program then a request is made to OS for memory allocation. There are two types of memory allocations are used in programming.

Static
Dynamic

Static memory allocation is fix allocation. It cannot be change during run time. Static memory allocation is better option in case when we know exactly how much amount of memory need. For example holding roll number marks of student etc.

IDENT_CURRENT SQL Server

IDENT_CURRENT return last inserted identity field value from any session any scope table.

One most interesting things which surprise me while I had used this first time. Which is follows

You can get SQL server generated identity value which inserting row, means it is not necessary that identity value only can get after save a row. Not at all!

You can use this feature while creating some userid and roll number type field in many applications.

i.e: 10000001,2000829 etc.

CREATE TABLE dbo.stu(

ID INT IDENTITY NOT NULL PRIMARY KEY,

Roll varchar(20),

Name VARCHAR(40) NOT NULL

City VARCHAR(40) NOT

Sort an Array using pointer

Q : What do you mean by a pointer variable? Write a function in ‘C’, using pointers for the array of elements, for sorting the elements.

Pointer

A pointer is a special type of variable which hold physical address of a non pointer variable.Symbol * is used to make a pointer variable.

Structure Example

Q : What is meant by structure data type? How do we reference the elements of a structure?
Give example of how a value of a structure can be assigned to another structure.

Solution :

A structure is user defined data type which is used to store record based data. Structure is useful when there is a need to process record type data for example student record which is a combination of more than variable (roll,name,class,marks etc). Structure encapsulates more than one variable into a single logical unit. Without structure, processing of record based data is not an easy task. Programmer need to declare many variables with different name. Which increase complexity?

Thread

A thread is a basic unit of CPU utilization; it comprises a thread ID, a program counter, a register set, and a stack. It shares with other threads belonging to the same process its code section, data section, and other operating-system resources, such as open files and signals. A traditional (or heavyweight) process has a single thread of control.

Application

Many software packages that run on modern desktop PCs are multithreaded. An application typically is implemented as a separate process with several threads of control.

HTML Table Operation

Hide Table Column

$('#table-name th:nth-child(column-no)').hide();

$('#table-name td:nth-child(column-no)').hide();

Example:

$('#tblService th:nth-child(4)').hide();

$('#tblService td:nth-child(4)').hide();

Print All columns of each row

var table = $("#tblBody");

table.find('tr').each(function (i)

{

var $tds = $(this).find('td');

alert ($tds.eq(0).text() + " , " + $tds.eq(1).text())

});

Print All Row columns except first

var table = $("#tblBody");

table.find('tr').not(':first').each(function (i)

{

var $tds = $(this).find('td');

alert ($tds.eq(0).text() + " , " + $tds.eq(1).text())

});

Get selected column data using rowid

Syntax:

$("RowId”).find('td').eq(ColumnIndex).text();

Example :

$("#r123”).find('td').eq(0).text();

Delete a Single row by row id

Syntax:

$("RowId”).remove();

Example :

$("#tblrow").remove();

Delete all row except first

Syntax:
$("selectorName").find("tr:gt(0)").remove();

Example :

$("#tblStock").find("tr:gt(0)").remove();

AddCss("txtMessage");

}

function AddCss(id) {

Flag = false;

$("#" + id).css("border", "solid 1px red");

$('#' + id).animate({

'marginLeft': "+=10px", //moves right

}, 100);

$('#' + id).animate({

'marginLeft': "+=-10px", //moves right

}, 100);

$('#' + id).animate({

'marginLeft': "+=10px", //moves right

}, 100);

$('#' + id).animate({

Function

A function is a combination of more than one statement which execute together one by one to achieved some specific task. Function code run while calling. There are many variety of functions some takes arguments and return something or takes argument and doesn’t return and more.

C language is known as building block of function all the things of programming is achieved through function. Program gets start running with main function.

Types

This type of function neither returns anything nor takes arguments. When a function doesn’t have something to return then void is used. Void indicates no return.

Example
