Cloud Computing is a magic term which is mostly heard in the recent past among the technical world Devs. For those who never knew what is a cloud (in technical terms), let me put a simple description – Cloud saying to a Dev “You build the app, and I will take care of production environment”, its as simple as that. Even Microsoft don’t want to let their proportion of coders go down, it immediately came up with Windows Azure, Microsoft Cloud Platform. Windows Azure consists of mainly three important parts – Windows Azure (a place to manage the hosted services), SQL Azure ( to manage the data storage to DB) and AppFabric (used to build, scale and manage Web). Essentially a dev need to get accustom with all these three parts sooner or later.

Simple Html Editor based Comments Section with Captcha feature along with Database Interactivity
RamiVemula on August 29, 2010 at 7:32 pm
In this tutorial, we see how to develop a simple comments section. This comments section is going to be a similar one to what we usually see in our day to day experience. Here we use TinyMCE editor to enable Html Comments. And also catpcha is enabled (with the help of reCaptcha of Google). The basic outline would be – Users provide their general details like name and email, and also they can provide Html Comment (using TinyMCE), and finally they should enter the text showed in the captcha for validating robots. Then we take the Html string, encode it using HtmlEncode(), store it in database. Finally we retrieve the encoded string from the database, we then decode it and display it in the page as Comment.
Create a Simple WCF Service Client against Pubs Database using EF, LINQ – Part II
RamiVemula on August 10, 2010 at 9:25 pm
1) In this tutorial (which is PART – II), we create a small website in ASP.Net 4.0 and we shall use a WebForm (named: PubsServiceTestPage.aspx) as a client to our service (which we created in former tutorial).
2) We Use the inline model of Webform (not the codebehind model).
3) We perform the actions using our client like, Getting all the Authors and display them in the Dropdownlist for selections, Selecting a Author and display his corresponding books using a Repeater, Modify and save the book details back to database etc.
4) To test the Client, we need the service to be running in the server, that can be simply manipulated by starting another instance of VS 2010 and running (Ctrl + F5) the PubsService.svc.cs.

Create a Simple WCF service against Pubs Database using EF, LINQ – Part I
RamiVemula on August 10, 2010 at 7:56 pm
1) In this tutorial we create a simple WCF service which is used to retrieve and save data from Pubs Database (Microsoft sample database).
2) The service also demos on how to use EF 4.0 and LINQ against database coding, with no requirement of writing SQL queries.
3) The continuation of this tutorial shows on how to create a client (say a WebForm in a website) to utilize this service.
