SQL SERVER - 2005 - 2008 - Delete Duplicate Rows

Thu, 02 Jul 2009 07:00:00 GMT

This method is improved over the earlier method as it not only uses CTE and ROW_NUMBER, but also demonstrates the power of CTE with DELETE statement. We will have a comprehensive discussion about it later in this article. For now, let us first create a sample table from which we will delete records. A Must BookMark!

OpenForum - A Free Forum for ASP.NET MVC Applications

Tue, 30 Jun 2009 15:15:01 GMT

One of the things that I really like about the MVC framework is that it offers some unique possibilities when it comes to third parties developing entire sub-systems that can easily be plugged into existing applications. Recently, I had some "down time" at my work and decided to take the opportunity to experiment with doing just that. Here are the results of that experiment. OpenForum is a forum that can easily be plugged into any MVC application with very little effort. In fact, there are only three steps to get OpenForum working with most MVC applications.

Never worry about ASP.NET AJAX's "d" again

Since a lot of people are having trouble with it, I want to share one method you can use to completely isolate your code from the ".d" problem. In this post, I will show you how to detect the ".d" and how you can completely isolate your $.ajax success handler from it.

Session Attacks and ASP.NET - Part 2

Wed, 24 Jun 2009 19:00:00 GMT

In Session Attacks and ASP.NET - Part 1, I introduced one type of attack against the session called Session Fixation as well as ASP.NET's session architecture and authentication architecture. In this second post, I'll delve into a couple specific attack scenarios, cover risk reduction, and countermeasures specific to ASP.NET for protecting against session attacks in ASP.NET

If At First You Don't Succeed - Retrying Mail Operations in .NET

Mon, 29 Jun 2009 19:45:01 GMT

Mail sent from your application didn't go through? Don't give up so easily! The majority of mail server interruptions are very temporary in nature, lasting only a few seconds. Instead of failing right away, why not give your SMTP client another shot?

Avoiding The Database Deployment Nightmare

Fri, 19 Jun 2009 12:01:25 GMT

So, I have written before about how to put your database into version control using database projects in Visual Studio. Even while having the scripts in the solution, there can be times when you can't exactly remember what you changed and needs to go out with your project deployment to the production database. Deploying files is easy because of tools like WinMerge, however deploying things to a database can get quite complicated. You could script both schemas and use WinMerge to see the differences between the development database and the production database. But even doing that, you will still have to write a custom script to get the production database schema up to date.

WPF Bindings and CurrentCulture Formatting

Thu, 25 Jun 2009 22:00:00 GMT

WPF doesn't apply the CurrentCulture to bindings by default, which is a little... unexpected to say the least. As it turns out there's an easy solution to this problem, but it does require using code to apply the culture specifically in every document.

How do ASP.NET Application_ Events Work

Fri, 19 Jun 2009 06:03:41 GMT

Most of us have used ASP.NET global.asax Application_ EventName handlers, but do you know how it is that these events are actually fired automatically by ASP.NET even when you add additional events by name? In this post my curiosity got away from me and I took a look under the covers to see what ASP.NET is doing to hook up these method to HttpModule events.

Dissecting the JQuery text method

Thu, 18 Jun 2009 19:00:03 GMT

An interesting question came up at work today. We had some existing code that was using the innerText dom method. It worked fine on IE, but not on Firefox (to be clear, I'm used to that working the other way around). If you look at QuirksMode you will see Firefox is the only browser that does not support this method as well. Turns out if you use innerText on any dom element in IE you will get the text inside the element (in this case a span tag), but in Firefox you just get nothing. Time to see how JQuery does what it does.

Model View Presenter (MVP) design pattern and data binding

Tue, 09 Jun 2009 10:45:00 GMT

Model View Presenter (MVP) design pattern is the evolution of the MVC design pattern and it's aimed at providing a cleaner separation of concerns between the view, the model, and the controller improving the architecture (you can use several UI technologies without recompiling the business logic components) and testability of the enterprise solution. The pattern was originally developed at Taligent in the 1990s. In this article, I will explain the principles and how to use the MVP design pattern along with data binding with an example using C# language in Microsoft.NET.

A Degradable jQuery AJAX Email Form for ASP.NET MVC

Mon, 08 Jun 2009 07:45:10 GMT

Pretty much every web site on the Internet features a form for users to provide feedback via email to site owners. Migrating to ASP.NET MVC requires a slightly different approach to that used by Web Forms development, so this article looks at one way to implement a web site contact form using the MVC framework and jQuery that degrades nicely. AJAX functionality is said to be "degradable" if a way is provided for the process to work, even though users don't have Javascript available to them.

ASP.NET MVC and Localization

Thu, 28 May 2009 01:54:55 GMT

I live in Montreal - Canada, and here we have two officials languages, French and English, that's why every website I build must be available in both languages. Building an ASP.NET MVC Website using Localization/Globalization is fairly simple and is pretty much like doing it on a plain old ASP.NET Website.

The Greatest Exception Handling WTF?!? of All Time

Thu, 28 May 2009 10:00:00 GMT

The Exception object has ONE purpose and ONE purpose only - to represent a runtime error, nothing more. Exceptions should never be used for purposes for which they were not intended -- or you could end up with this monstrosity...
