A recent article announced the possibility of 60TB hard drives by 2016.That's only 4 years from now, about as long as this blog has been around (2008-2012), and after seeing that article all I could think was who cares, by 2016 we will all be using 60TB SSDs anyway....I know what you're thinking: "Whaaaa?!? 60 terabyte SSD?!? I just bought a 60/120 gigabyte SSD, how are they going to have 60 terabyte in 4 years?!?"oh technology, how I hate and love your rapid declining prices. June 2010 a 64gb SSD...
If you have a GridView that uses BoundFields but does not display line breaks or a lot of spaces quite right here is a way to get around that. This example uses a GridView with one BoundField that uses a DataField of comments. The comments are stored in a database and entered from another page which displays the comments properly in a textbox with all the spaces and line breaks you intended. The trick to get a BoundField to show those items is to take the item and replace the \r\n with a <br />...
I would highly suggest subscribing to PluralSight if you are wanting to learn different technologies and frameworks.

The videos are well designed and the screens are also well designed to be comfortable viewing on smaller screens such as the phone...
If you are a Windows Phone enthusiast, or really into the Windows 8 platform that is coming soon, then I ask you to consider sunny Baton Rouge, Louisiana as your vacation spot this coming August 4 for SQL Saturday And Tech Day. I know what you’re thinking: “Paul… Isn’t this a SQL event?” Laws yes, it is a SQL event, however we’ve secretly taken this SQL event to our secret underground cool-ification bunker (and dinosaur exhibit) and injected it with AWESOME and bombarded it with large amounts of...
I found many websites that showed either misinformation, incorrect code, or denial of the ability to use a class as a datasource for an asp.net listview control. It is actually very simple.First you need to define your class. I created private fields and public property to get and set values for those fields. I then created a static function (since it is used often) that would return a list of the class type.In my case, I was looking for documents that matched the page and page section so I can list...
It’s really exciting news that new SDK V1.5 Kinect for Windows was released on May 21st 2012. There are lot of new features and enhancement made as part of this release.

For the last two years, I’ve ordered the Nimble Pros Software Craftsmanship calendars, which use ‘motivational poster’ style pictures to depict various software practices and principles worth keeping in mind. Here’s one of the walls at work, where I’ve got the calendars cut up and displayed for easy reference: I like being able to point to a principle when its use pops up, and they provide a nice illustration of things everyone should be aware of. I’ll be following this up with a post on each month’s...
Team Foundation Server 2010 is a “server-side” version control system. Developers used to Subversion and other “client-side” systems are often frustrated in certain situations where they want to see only the changed items in the Pending Changes window and TFS shows all checked-out items. This happens when an entire directory structure is copied to the workspace and only some of the items have changed. The rest are identical to the existing items in the workspace. The typical procedure taken is: Check-out...

Much has been written about the technical ins and outs of localizing .NET applications with ResX files, but I think that most treatments of the topic understate the difficulty involved in localizing a project of substantial size and complexity. You probably already know how to define and consume global and local resources in a “Hello World” sized ASP .NET application and how to use the CurrentUICulture to ensure that the right version of a string is pulled from a ResX file to be shown to a user....
The rise in demand for database continuous integration has forced me to skill-up in various new tools and technologies, particularly build servers. We have been using JetBrain’s TeamCity here at Red Gate for a couple of years now, having replaced the ageing CruiseControl.NET, so it was a natural choice for us to use this for our database CI demos. Most of our early adopter customers have also transitioned away from CruiseControl, the majority to TeamCity and Microsoft’s TeamBuild. However, more recently,...
If you used the latest MVVM Light version for Windows 8, you may have noticed that a couple of issues cause your app to fail the Windows App Certification Kit. It is really quite simple: By mistake, I published the debug version of the assemblies instead of the release version. This causes the certification to fail. I already published an update on Nuget, so if you have created your application and added the DLLs using Nuget, you can update with the steps described her (scroll down to the “Updating...

Many years ago, when I was working for a media company in London, I would dial-up the office system in the evening. (This was in the days when 2400 baud was fast!). One evening I noticed one of the directors of the company was connected and emailed him the message "Good Evening Mr Director Sir".The following day, I met him in the office and he complemented me on my message - he was working with a client on a rush job and the client was very impressed by the respectful message.So when you email, be...
Delegates in .NET are a very handy addition to the language. With the introduction of LINQ they did become mainstream and everyone is using them or is at least finding them cool. But what the CLR is really doing to them under the covers remains largely unexplored. This is ok as long as you never get any memory dumps from the field with angry customers waiting for a solution. Delegates are heavily used to e.g. send window messages from an arbitrary thread to the main UI thread. Or you have an thread...
I have written a nifty little tool in PowerShell that eases the deployment of SharePoint solutions (WSP) files. The tool serves as a management tool for new features. It uses an XML configuration to select a bunch of solutions and deploys them to the farm. Now, despite our best intentions and the best efforts of QA, we somehow manage to upload solutions that do not do exactly what they are supposed to do, or – horror of horrors – even disrupt previous behavior. So, the tool is also used to restore...

I am sure you have been in the situation where you start following a change through the list of builds and suddenly realize a lot of the builds have been deleted by some one!

In this blog post, I'll give you a walkthrough on how to write a simple utility to get the list of deleted builds and their details using the TFS API. Download...
HTTP 400 Bad RequestHTTP 404 File Not FoundAnybody who has done some web development would have surely come across these errors. These could be arguably most popular error codes in the HTTP 4xx family ;). Let's take a deeper look at what are the other common errors and the possible reasons for that. Well, there are uncountable resources in the web on HTTP error codes and I need not add one more on top of it. Let me explain my stand then. I was getting complaint that a consumer of one of my web service...
This book is exactly what its title says - a reference book for XAML. It covers all major areas of XAML related programming - focussing mostly on WPF and Silverlight. My reactions to reading the book – I did find a few gems in the book, but generally it is a reference book and is intended to be read as a reference book (in small sections as needed or as a general overview). At times I did ask myself what value I was getting from the book vs reading online references like MSDN but if you are the type...

Ive been speaking to a few people starting their organisations first BizTalk projects recently and talking about Host setup and what is a good intial setup and how it may change over time. Normally you see companies go one of two ways to begin with:1. They just have one BizTalk host with an instance on each server and use it for everything2. They have many instances for everything and use way more than they need to.Im a big believer that a little thought about this and how your company plans to use...
Since I have been interested in cross-platform mobile application development, but reluctant to leave behind the IDE goodness that is Visual Studio, I was invited to participate in a private early beta program for VSNomad and asked to share my thoughts. One of the coolest things about the tool is that there is hardly anything to it, so most of this blog entry will be focused around the motivations for a tool like VSNomad rather than "all the things it does". Access to the early beta program is "by...

Entity Framework is an object-relational mapping framework that can be used to work with data as objects. While you can run the ADO.NET Entity Data Model wizard in Visual Studio to handle generating the Entity Model for yourself, this can put you at a disadvantage if there are changes in your data source or if you want more control over how the entities operate. In this article we will demonstrate a Code First approach to accessing your QuickBooks Data using the RSSBus ADO.NET Provider. Even though...

One of the problems that I face is having to periodically rebuild my development PCs.

Once again, in this series of posts I look at the parts of the .NET Framework that may seem trivial, but can help improve your code by making it easier to write and maintain. The index of all my past little wonders posts can be found here. We’ve talked about the Select() and Where() LINQ extension methods before. The Select() method lets you project from the source type to a new type, and the Where() method lets you filter the list of items to the ones you are interested in. Most people know of these...
This might not be news to you but for me this was a discovery i made only this week, yes how did i not know this before! So I discovered how to pin any folder to the Windows Explorer jump list on the Windows 7 task bar. Any entries in the 'Frequent' menu can be pinned using its context menu, but a folder that does not appear in the 'Frequent' menu can still be pinned just by dragging its path from the address bar in the Explorer window onto the task bar icon. The pinned folders can then be accessed...
