Chakravarthy — Tue, 25 Jan 2011 14:16:30 +0000

I’ve written the mentioned exam and completed this in the second attempt. I’ve failed in my first attempt, but passed in the second attempt. The second attempt for all the Microsoft exams is free. One of my friend asked me about the highlight points that helped me to attend the exam. This post arrived while preparation of the bulleted points that I recollect from the exam.

The whole exam pattern can be divided into 3 + 2 = 5 sections. The first 3 sections are more concentrate on the enhancements in v4.0 along with the traditional questions from v3.0 based. The second 2 sections are mainly into configuration and deployment of any web app that is developed using ASP.NET v4.0

To make the long story short, here is the full details that I’ve in my mind. Ofcourse, I’ve not mentioned any thing about MVC as a separate section, because, MVC is a pattern for me but not a new enhancement from the point of framework. Having mentioned that you can even consider that there are few questions pertaining about MVC too, thus, don’t forget to give attention towards MVC.

1) Traditional WebApplication questions

1) How to Configure Web Forms pages

5) How to implement caching and how to manage view-state & Validate user input

2) Questions that are new to ASP.NET v4.0 Controls

6) What are user controls and how to implement
7) What are the mechanisms using which we can manipulate user interface controls from code-behind

What controls help to Display and Manipulate Data
9) What are the new ways to implement DataBound / DataSource controls

10) Query and manipulate data by using LINQ (ofcourse, this doesn’t new to v4.0 but the exam questions are based on v3.0 LINQ)

3) This section is about new enhancements from ASP.NET v4.0

11) What is Client-Side Scripting and AJAX
12) How to induce the dynamic features to a page by using JavaScript
13) How to handle JavaScript events

3.1)Services Enhancements

Sending SMS from .NET Application

Chakravarthy — Tue, 14 Dec 2010 16:57:05 +0000

Today, when visiting the MSDN forums, came across of a request about the subject of this post. While replying, thought of writing a post with visual aids. So that it would be more meaningful. But unfortunate that MSDN forum doesn’t support to upload the Images. Hence is the blog post.

Before we talk about .NET application, it is required to understand how SMS works and the integration with some application. Thus, let’s see what happens when some one sends SMS. Am not going to talk about SMS sent to any phone with 10 digits unique number, but am talking about sending SMS sent to less than 10 digits number, sent on some reserved interfaces (or) mass SMS receiving mechanism. Mostly these kind of requirements come into action when polling is required or a kind of reality shows like American Idol in USA and Sa Re Ga Ma Pa from Zee Tv in India.

Let’s start with how this kind of polling is offered by the Providers, called as SCS Providers ie., Short Code Service Providers. Any business person who is interested to utilize the services of such SCS first has to register with these SCSProviders. The SCSProviders charge according to their business plans. Here is a simple example about the pricing by one of the Indian SCS Provider

Short Code Number: 53426
    Short Code: As per request *(subject to availability)
    Sub Keyword: Multiple ( e.g. )
    Control Panel: Web Based
    Auto-Welcome: An SMS will be send to the customer who will send your short code. This message can be customized from control panel. You can create different Welcome message for sub-keywords also.

Reports: Daily Keyword/Sub Keyword based
Database: Database of received SMS will be available in your account with us. (Web Based)
Auto-Forward:To SMS (An SMS will be sent to desired number with Sender’s Mobile Number SMS Forwarding Cost: 25 P/SMS)

To Email (An Email will be sent to desired mail id with Sender’s Mobile Number, Keyword)
Web URL (This will submit the sender’s mobile number and keyword to desired web-page and the result of the page will used as Reply Back SMS. This web page could be dynamic in nature to give any user specific reply back. e.g. Result of Exam through SMS Request)

Network Support: All India
    Setup Time: 48 Hrs. after approval of Keyword availability
    Setup Fee: NIL
    Monthly Rental: 4,500/- [4500 + 556 (Service Tax): Rs.5056]
    Quarterly Rental: 4,000/- [12000 + 1483 (Service Tax): Rs.13,483]
    Half Yearly Rental: 3,500/- [21,000 + 2596 (Service Tax): Rs.23,596]
    Yearly Rental: 3,000/- [36,000 + 4450 (Service Tax): Rs.40,450]

Rs. 4,450/- Off on Yearly subscription.

One Year Pricing (after discount): Rs.36,000/-

Hope you are now clear about the pricing details of any SCS Provider. Let me show you how the SCS provider works with some visual representation. The infrastructure and the working model would be some thing similar to that of the below mentioned

Now that you understand how your SMS communication is implemented in real world, let’s see how this can be extended so that any application can handle the situation when SMS received as well as sent.

Most of the SCS Providers do the URL Forwarding, which means they invoke any of the given URL when they get an SMS. Thus, it is the responsibility of the business application to provide any URL to receive the information about the SMS. The URL would be some thing like, http://mybusiness.com/getsms.aspx?phonenumber=93829283928&message=thisiscool

Which means that the business owner should expose some interface by means of a WebPage (or) WebService (or) what ever is feasible for the business. Once the business application gets the information, it is all within the workflow of the rules that is orchestrated by the business owners. The entire crux of this post remains in this last paragraph. Well, for a web developer, I don’t think it is required to explain how to collect the query parameters as well as send any query parameters. This is all fine to collect the SMS sent by the users on a reserved number like 53426. But now, how about sending back some information to the phones via SMS?

As you see in the diagram that every SCSProviders have a feature called as URL Forwarding, they would also be having a web page where you can send some data that would be passed onto the SMS sender. The page that is provided by the SCSProvider would be some thing like http://SCSPWebSite.com/sendsms.aspx?phnumr=93829283928&message=thisisreply .. Hope now you are totally aware of how to send SMS with the help of SCS Providers as well as receive SMS in a web application.

Visual Basic is the Core attention by Microsoft

Chakravarthy — Mon, 29 Nov 2010 16:44:33 +0000

Workflow foundation is currently at 4th version. The main coding syntax that is expected for any of the code activities are more from the VB code syntax. Hence, it is proven that Microsoft considers VB as primary language while doing any kind of Research.

Apart of this, there is one more fact that there is a recent toolkit released from Microsoft, just yesterday, ie., 28th Nov 2010. It is RTW for Windows Phone developer. This release enables Visual Basic developers to create Silverlight applications for Windows Phone 7 using the final version of the windows phone developer tools.

You can download the Windows Phone developer tools RTW from this link.

Don’t think that this is a false or fake news. I usually configure my outlook with my msn account. To my surprise when I’ve seen the server status of my MSN account, am surprised to learn that MSN is allocating 500 GB space for each mail account. You don’t believe me!! Here is the proof. See the below image, still you don’t believe that I’ve a valid point and you trust that the image is morphed by me.. ha ha ha.. then come and meet me personally, I’ll show you from my laptop.

Apart of all, how it would be, if i recommend you to configure your MSN account with your local outlook!!! Sounds great right!! Then you don’t have to suspect me, you can witness yourself. Try it ..

SVN Repository Migration

Chakravarthy — Wed, 07 Apr 2010 15:04:42 +0000

Our current employer decided to have the code base as VisualSVN. So we stated a demo server and then after successful trail started a staging server for our project. For the entire March month it worked well, and we decided to have another VisualSVN server as production. During the last week we have decided to migrate our staging SVN source to production box, but now the problem is about history or revision of the full one month.

After binging and googling, I’ve found many alternatives. Most of all, I’ve realized one simple solution and migrated the entire code base from staging to production as simple as cake biting.

Problem :

Source SVN is at 10.4.5.68 and the repositories are installed at D:\

Target SVN is at 119.18.112.63 and the repositories are installed at E:\

Solution:

Step 1:

Copy all the project folders from 5.68\d$\repository\<> to 112.63\e$\repository\

Step 2:

Copy the auth files from 5.68 to 112.63, this would copy all the users along with their project groups

Step 3:

Go to the client side and just relocate your SVN url by right clicking on the folder and point to “SVN=>Relocate”

That’s is done.. did you try?

Am a big favorite of EntLib. I started using this from v1.1 during June 2005. The good thing from the latest version is that they are not adding any more blocks, on top of it they are removing some unwanted code.

They are targeting to release this by 14th of April after 2days of VS2010.

What’s behind name, "Microsoft"

Chakravarthy — Tue, 12 Feb 2008 06:18:59 +0000

Did you ever thought that Bill Gates named their company as “Microsoft”?.. it was a billion dollar question to me all these days. At the early days when Bill is forming his company along with his friends, sought recommendations for a good and fancy name. Every one gave their won stylish and trendy names. They are not ready till their first cheque is due to them. While Steve Balmer is talking about a product that is the brain child of Bill, mentioned as “.. it is a SOFTware for MICROprocessors .. “, these words lead the idea to name their company as Microsoft. And the rest is history and preset.

Does any has proof to violate this information??
