After trying to create its own big data management platform, aka dryad, LINQ to HPC, Microsoft has decided to stop researching on it and exploring Apache open source big data platform HADOOP. A well established and widely used big data platform for performing computation over big data. 

With partnership of Hortonworks, Microsoft has successfully delivered HDInsight: Hadoop Eco-System for Windows Server and Windows Azure. Also empowered Microsoft's products SQL Server, Excel, C#, LINQ to work with Hadoop Eco-System.

Refreshing Parent window when Pop Up window is closed in Java Script

Open a pop-up:

We have two very easy and common way of opening a new window in JavaScript.

1. Using winodw.Open() method.

window.open("http://expressdotnet.blogspot.in/","","width=200,height=100");

2. Using window.showMModalDialog() method.

window.showModalDialog("http://expressdotnet.blogspot.in/", "", "dialogHeight: 481px; dialogWidth: 718px;")

Refresh Parent window:

1. When using window.open() method, we get reference of parent window from window.opener property.
use window.opener.location.reload() method to refresh parent window.

2. When using window.showModalDialog() method, new window opens as a modal dialog and execution of code of parent window stops until pop-up gets closed.
we can use this behaviour and can call window.location.reload() method, just after line window.showModalDialog().

Very Often while working with data, our requirement is to retrieve which data has been modified and keep to data in two tables in synchronized. For achieving this task SQL Server has provided many way such as CDC (Change Data Capture), rowversion datatype, MERGE statement and various other alternatives using such as joins , storing datetime etc, which can be used based on our requirement.
Here, we will discuss about rowversion datatype and see a small demo how we use rowversion to Sync data changes done in a table to other table.

WCF Security Basic: Part 1

WCF Security is a very wide topic. So it is better to break into multiple parts to understand it better. In this part, I will be covering very basic of it.

In WCF, We can apply security measures (authentication and Encryption) at two points when sending and receiving messages:

• At Transport Level. 
• At Message Level.
