How to use jQuery setTimeout function and setInterval function

setTimeout: This method is used to delay execution of some code. It is used to execute a certain function or jQuery code at the end of given time. It takes the time in milliseconds.

Syntax of setTimeout:

setTimeout(function () {
    // Do something after given time
}, Time in millisecond);

For example you want to hide a div, 5 seconds after the page loads, then you can do it as:

<div id="exampleDiv">This is example div for set time out </div>

setTimeout(function () {
}, 5000);

This script will hide the “exampleDiv" after 5 seconds, Check live demo on jsfiddle.

setInterval: This method repeats itself at regular time that is passed to this function, we can compare this method to an alarm clock that strikes repeatedly after a particular interval. It also takes the time in milliseconds.

Syntax of setInterval:

setInterval(function () {
    // Do something per given time
}, Time in millisecond);

For example we want to multiply a number by 2, every second:

<div id="testInterval">1</div>


setInterval(function () {
    $('#testInterval').text(parseInt($('#testInterval').text(), 10) * 2);
}, 1000);

Default value in div is ‘1’ which is string so we’ll convert it into integer value with the help of parseInt() method, and it’ll be multiplied by 2 every second, Check live demo on jsfiddle.

C#: Merging Excel cells with NPOI HSSFWorkbook

In this post we’ll see how to merge the two or more cell with each other while creating the excel sheet using NPOI.
Mentioned below is code to merge multiple cells, in this example we are merging first cell to fifth cell of first row (you can adjust row or cell range by passing particular parameters in CellRangeAddress).
//Created new Workbook var hwb = new NPOI.HSSF.UserModel.HSSFWorkbook(); //Create worksheet with name. var sheet = hwb.CreateSheet("new sheet"); //Create row and cell. var row = sheet.CreateRow(0); var cell = row.CreateCell(0); ; //Set text inside cell cell.SetCellValue("This is Merged cell"); cell.CellStyle.WrapText = true; //define cell range address // parameters: -> first row to last and first cell to last cell var cra = new NPOI.SS.Util.CellRangeAddress(0, 0, 0, 4); //Add merged region to sheet. sheet.AddMergedRegion(cra);
Hope this solution helps you J

Calculate Sum and average of two or more Textbox values using JQuery

We can calculate sum and average of values entered in textboxes with the help of small piece of jQuery code.
First of all let’s create a HTML form where we’ll ask user to enter marks in each subject, under body section add following HTML:

Difference between Web API, WCF and Web Service

So now we have got the basic idea about Web API, now let’s do some comparison of Web API with WCF and web services.
Web Service WCF Web API Web services created as file with .asmx extension. WCF create with .svc extension Web API are simple class file with .cs(for C#) extension. Web API is inherited from “ApiController” and class name must end with “Controller”. It is SOAP based service and return data in XML form. It is also based on SOAP and return data in XML form. Web API is HTTP based service and by default it return data in JSON or XML form. It supports only HTTP protocol. It supports various protocols like TCP, HTTP, HTTPS, Named Pipes, and MSMQ. It supports HTTP protocol. It can be hosted only on IIS. It can be hosted with in the application or on IIS or using window service. It can be hosted with in the application or on IIS.
