Introduction
In this article I want to show how to create date picker in AngularJs
Introduction
In this article I show how to import a csv file and view in a gridview.
Introduction
The purpose of this article to show Date & Time using jquery.

Any Service that we develop might get some error. Basically we can not see what wents wrong actually in our and where cause the error. We handle this problem using Fault Contract.
Why Multithreading in C# and ASP.Net
Usage of multithreading in .Net can be very useful for different use cases.
- Suppose in your web page there are multiple report that needs to be generated based on different complex queries, stored procedures or functions. If you execute one query at a time and populate the Report in GridViews, it will take longer time to complete. Instead of this if you execute multiple queries in parallel and populate those GridViews then the maximum time it may take up to the time to execute the query that take longest to finish.
- Sometimes in your page there might be scenarios where you want to show one particular set of data. But if user wants then they can click a button (Lets say "Show More") and then more data can be shown. You can optimize this kind of scenario by getting data in advance for "Show More" button and that you can easily do by using threading and storing the data in the page and retrieve that by Javascript when required.
So threading could be a game changer for your website if you can effectively use it.
In the below example I have shown a simplest threading implementation where two different methods has been called by Threading or Non-Threading way and we can see that how Threading way of implementation is executing faster.
Default.aspx.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Threading;
namespace TestWebApplication
{
public partial class Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
/*
Serial Execution
*/
writeLn("Without Threading");
writeLn("==========================");
DateTime dt1 = DateTime.Now;
writeLn("Started at " + dt1);
doWork1();
doWork2();
DateTime dt2 = DateTime.Now;
writeLn("Ended at " + dt2);
writeLn("--------------------------");
writeLn("Time Taken: " + (dt2 - dt1).Seconds + " Second");
writeLn("");
writeLn("");
/*
Parallel execusion by using Threads
*/
writeLn("With Threading");
writeLn("==========================");
DateTime dt3 = DateTime.Now;
writeLn("Started at " + dt3);
Thread t1 = new Thread(new ThreadStart(doWork1));
t1.Start();
Thread t2 = new Thread(new ThreadStart(doWork2));
t2.Start();
t1.Join();
t2.Join();
DateTime dt4 = DateTime.Now;
writeLn("Ended at " + dt4);
writeLn("--------------------------");
writeLn("Time Taken: " + (dt4- dt3).Seconds + " Second");
}
private void doWork1()
{
writeLn("First Method Started");
Thread.Sleep(1000);
writeLn("First Method Ended");
}
private void doWork2()
{
writeLn("Second Method Started");
Thread.Sleep(1000);
writeLn("Second Method Ended");
}
private void writeLn(String msg)
{
Response.Write(msg + "<br />");
}
}
}
Output
Without Threading ========================== Started at 7/15/2016 12:55:52 AM First Method Started First Method Ended Second Method Started Second Method Ended Ended at 7/15/2016 12:55:54 AM -------------------------- Time Taken: 2 Second With Threading ========================== Started at 7/15/2016 12:55:54 AM First Method Started Second Method Started First Method Ended Second Method Ended Ended at 7/15/2016 12:55:55 AM -------------------------- Time Taken: 1 Second
For using Threading more optimize way in .Net you can read about Thread Pool and implement that as and when required. Will definitely write in near future on Thread Pool in .Net.
Introduction
It is very difficult in our angular application, when we using service and get a asynchronous call from it. Sometimes response is coming without any result. Because our request do not wait for coming value from server side. To resolve this problem angular give us $q constructor. So that we can get all the result. In this article I going to explain how to call asynchronously using promises and $q service.
This discussion can be useful for following types of question as well
- How an event can be fired by selecting a combo box / Drop Down List box in android?
- How spinner's activity can be tracked on a change of a item selection?
What is generics?
Generics force you to use a specific type (Class or Interface) when defining your Interface/Class or Methods.
