In 1983, the term Exploratory Testing was introduced. Prior to that, it is called as ad-hoc testing. Exploratory testing is said to be a mindset, a way of thinking, freestyle testing that liberates the tester to explore. Testers, through experience, know their applications inside out; they are the users in reality. Freeing testers to explore and use the application has been proven to identify more bugs then traditional scripted testing. However, there are obstacles and challenges related to this ...

Well, as mentioned in my earlier posts, the ASP.NET MVC 4 has Developer Preview has been released. You might notice quite a bit of this term “Developer Preview” in 2-3 products specifically. One, Windows 8 is now available as simply Windows Developer Preview. Similarly, Visual Studio 11 is Developer Preview and also the Internet Explorer Platform Preview 3 is a Developer Preview, as with the case with Expression etc., Now, to clarify on a few things which I learnt. The Windows 8, hereinafter referred ...
In response to a post from an anonymous individual on one of my posts (http://geekswithblogs.net/... regarding free Microsoft tools I thought a follow up post was required!

If you're working with large chunks of data, eventually you'll probably use a foreach loop to iterate through an enumerable data source and execute the same actions on each item (for example, do something to every DataRow in a DataSet). With the new Task Parallel Library (TPL) in .Net 4 you can execute these loops in parallel for a noticeable improvement in speed. .Net has had support for parallel programming since the 1.0 version, but the developer had to do (sometimes...) extensive work to create ...

At last, I can announce that ‘BizTalk Server 2010 Unleashed’ has been published and is available through major booksellers in both printed and electronic form. The book is not a new edition of the old ‘BizTalk Server 2004 Unleashed’ book from several years ago, although Brian Loesgen, our fearless team leader, provided continuity with that title. Instead, this is entirely new content written by a team of six authors, including myself. BizTalk Server is such a huge subject. It proved a challenge to ...
Metro-style apps are very similar to Windows Phone apps. They have a similar application model (for example they can be suspended, and when suspended they can be killed by the operating system if memory is needed), so they need to maintain state. Also, and that is the topic of this post, they cannot be ended by the user in a “normal” way, i.e. there is no File / Exit menu and no “X” button in the corner. Once started, the application remains in memory until the following happens: Read the rest of ...
Microsoft loves MVVM and INotifyPropertyChanged so much that they included this very useful interface twice in the new WinRT framework. Unfortunately, only one of these is working correctly (and the other one is likely a bug, remnant from the past ) Read the rest of this entry » ...
So its been a few weeks since Microsoft’s Build conference, where they unveiled Windows 8 and shared what the developer story will be. I had blogged about Day 1 of the conference here, but I wanted to share some video I took with my colleagues Winson Woo and Jim Russell as my thoughts now that a bit of time has lapsed. So first, a video captured right after we got our hands on the Samsung tablet given to all attendees. Yes the tablet is nice, but this conference is all about the OS. Windows 8 as ...

I had written earlier about the WebMatrix v2 Beta release that happened recently at the BUILD Conference As I had mentioned earlier, WebMatrix is a light weight tool for Web Development, Profiling, Database management, Optimization and also deployment. Its an end to end tool for web developers. Web Matrix is different from Visual Studio in the sense, it doesn’t require web developers to master C#, ASP.NET and other programming techniques. Web Matrix uses a simple Razor syntax and HTML markup for ...
Yesterday I got to participate in a very encouraging experience. I got the opportunity to collaborate on a project I've been working on with another talented developer. Being able to collaborate on this particular project allowed me to work with sql, which has been more in my wheelhouse lately and the other developer got to work with .net technologies, which is where he thrives. What's so special about collaborating with another developer you say? Well, it was more the way the collaboration took ...

The nice thing about unintended changes is that you never think it could happen until you get bitten by a nasty change. Microsoft did publish a complete list of breaking changes here which is complete to my knowledge. But although the intentional changes are listed there are side effects which can cause you to search for hours your (non) fault. One change was to create a new GAC for .NET 4 assemblies to prevent breaking applications which rely on the structure of the GAC introduced with .NET 2.0. ...
I have been watching the influencer interviews with Richard Campbell as well as the Build Sessions recently published on Channel 9. Like most of you, I am trying to learn as much as I can about this new platform in the shortest amount of time. That is why I’m going to share my list of Killer Build Interviews and XAML Sessions. Note: Click on the image thumbnail to watch the video. First up, Interviews. Working at Telerik means that you get big influencers and great hosts at events like Build. I have ...
I remember when Windows Framework Extensions (WinFX) came out there was ill-informed remarks that Microsoft had killed off the Dot Net Framework. The truth was that Microsoft had extended the framework. A similar problem seems to be arising with Windows RT and Windows 8 - the truth is that Microsoft is again extending the Dot Net Framework. I suggest that you read LHotka's article at http://www.lhotka.net/weblo... This article explains the tremendous extension to to the Dot Net Framework ...
Recently I was tasked with a file cleansing exercise. The endeavor looked simple, but the solution was not, I needed to prepare a file for processing, but wanted to first proof concept my approach so I opted to utilizing this opportunity to learn PoweShell. More about the task: I was supplied with a series of CSV files in which the data looked like 123,ABC,XYZ "1,2,3", ABC, "XY,Z" 123,"A,BC", XYZ As you can see this is something I think we may call alternating double-quotes comma delimited file with ...
I work for a pretty awesome company, Online Business Systems. We’re 250+ technology and business consultants located in Winnipeg, Toronto, Calgary, Edmonton, Portland, and Minneapolis. Throughout the summer different departments within Online’s central region office (Winnipeg) host a BBQ with donations collected going to the United Way. Today was the last one of the season, and the Tech Services group was in charge. So myself and my colleague Dave Gillies concocted a plan to assault the tastebuds ...
Download binaries and application – 32K Source code – 99K Background Recently I was looking for a .NET implementation of QR code generator. Most of components either use online services to generate and/or recognize QR code or the implementation was not “good enough” for my purposes. The most popular and very powerful Java implementation comes from google’s open source project code.google.com/p/zxing called ZXing (Zebra Crossing => Z=Zebra + X=Cross + ing). There I found a one-to-one c# port of ...

In Windows Azure, we have the DiagnosticMonitorTraceListener which can be used for writing diagnostics to Local resource (like a local storage in the Worker or Web Role) which can then be ultimately stored in Windows Azure Table/Blob storage (transferred automatically by the Diagnostics Monitor in Windows Azure based on config settings). We could either configure the Diagnostic Monitor using Code (in Role Startup) or we can use a config file for the same (called diagnostics.wadcfg). The code configuration ...
C++ is a very powerful language. Well written native C++ code can perform much better than managed languages like C# and Java due to optimizations that the managed systems are not able to perform during run-time compilation (if this is done at all, that is). This is great for developers who work on gaming technology for instance. For people concerned with game logic, performance isn’t necessarily priority number one, but productivity and the ability to express oneself without too much head banging. ...
I wrote a simple pager AjaxHelper extension. You can convert this to an HtmlExtension method by just removing the AjaxOptions and swapping out the AjaxHelper with HtmlHelper.

Today we did the marshmallow challenge. For those that are not familiar with this challenge, it is a fun way to get teams to experience simple lessons in collaboration, innovation and creativity (that’s what their website says) and I would agree with them.

I just got back from Build 2011, and rather than spout my own theories (I’ll get to them later), I want to point you at a post by Kieth Elder. Basically, he says that there are two modes of using data, creation and consumption. Metro is for consumption, desktop mode is for creation. I think he’s spot on! Technorati Tags: Windows 8,Metro ...
Introduction One of the things that we all look at before we ship software is the performance of our apps. Last November, I posted a quick and easy way to do it in Silverlight. Today, I am going to walk you through doing it in Windows 8 for your Metro XAML applications. After the Build event was over, I was interested in learning how to do this for my Windows 8 Metro Apps. I started watching videos from the Build RSS Feed and noticed this one from Tim Heuer that did just that. Let’s get started Click/Touch ...

For more formatted view .. Goto http://ankitagrawal57.blogs... any web application, performance is basic necessity. Earlier internet speed used to be limited thus users got inclined to pages which load within 3-4 secs. But now the internet speed is no more a constraint but still time does remain a constraint. Imagine yourself visiting a website which takes a lot of time (30 – 60 secs) just to load the page. You would not like to go to that site again.To mitigate this issue, developers and ...

Yesterday I wrote this post but forgot to mention about something that is very close to my heart ASP.NET MVC. ASP.NET MVC has been evolving rapidly and within 2 years, we already have had 4 major releases (MVC 1, MVC 2, MVC 3 & MVC 3 Reloaded ) So, it doesn’t go as a surprise that MVC 4 is on the cards and the developer preview was unveiled at BUILD Conference. What does MVC 4 offer for web developers? Enhanced Default Project Template If you are bored with the vanilla blue template that comes ...
Last week I attended Build Windows conference and have been spending a considerable amount of time thinking how things have changed for developers. The initial reaction from most people was “Oh My God” with all the focus on WinRT and Metro UI and little mention of .Net, Silverlight, WPF, etc. You could almost feel the equal parts panic and excitement racing through the crowd. I was fortunate enough to have brought along my “Keep Calm and Carry On” T-Shirt to Anaheim. I wore it on Wednesday as it ...
I had dinner the other night with my good friend Josh Smith, and of course we started talking about Windows 8. Something he said was pretty much spot on: He said that Windows 8 feels as if it has split personalities. There are the WinRT “Metro-style” apps and there is the “classic” Desktop, which looks and feels like Windows 7++ (optimized for touch, and actually a real delight to use with my fat greasy fingers).

Introduction I’m sure by now you have heard that the Silverlight 5 Release Candidate has been released. I recently had a chance to Guest Blog for the Microsoft MVP Award Program Blog on “Getting Started with the Silverlight 5 Release Candidate”.

Ancestor RelativeSource Binding – Enables a DataTemplate to bind to a property ...
Are you passionate about your job? Do you enjoy programming? Do you think you're any good at it? One of the things that make me productive as a developer are the tools and products I use. However, these tools seem to try and grab all my attention. When I go to a conference, or read a blog entry, I'm bombarded with them: Windows 8, Visual Studio 11, TFS, WCF, Silverlight, MEF, OData, Lightswitch, LabManagement, NuGet, ... it just doesn't stop, and I know I will never be able to keep up with all of ...

At the beginning I want to inform that I've already read the similar question here: Entity Framework 4.0: is it worthy now? but it does not answer my questions and doubts concerning EF 4.0. Here's the case: We are working on a quite big project written in WPF and WCF. The structure of the database contains about 60 tables, lots of stored procedures, views and some functions. We are not using any ORM at the moment. Some time ago when the first version of EF was release we did not go with it because ...

What a week it has been! The BUILD Conference just concluded http://www.buildwindows.com... and there were tons of announcements. This is one of the reasons I am passionate about this company.

Recently I was assigned a task of helping a developer to cope with an unusual input file processing. The file we needed to load into SQL Server had double quotes surrounding those fields that contained comma(s). So a short excerpt from it would resemble something like: 123,ABC 456,"D,E,F" "7,89",GHS Since SSIS’s Flat File Connection does not support alternating text qualifiers, the chief difficulty stems from the fact if we even only remove the quotes, the file structure becomes broken because the ...
Do you know what happens when you create a new instance of a class? Why do we need a value type and a reference type? Do you know what is meant when the .NET framework is referred to as a “managed” platform? What is managed versus unmanaged code? Why do we need a .NET runtime? What is a memory leak; is that like an oil leak? All of these are questions that you should be able to answer as a Microsoft developer. If you can’t answer them all, then keep reading as the next series of research blogs that ...
I’ve added a second AppFabric Walkthrough based on the Azure AppFabric Service Bus September 2011 release. The second one looks at using the NamespaceManager class to create, list, get and delete queues in an AppFabric service bus namespace using a simple C# console application.

As with the first walkthrough there have been a lot of changes in the classes used to interact with the service bus, so don’t expect this ...
