HTML 5 and CSS: Six Complete Lessons

You want to learn HTML 5 and CSS? Microsft has created six complete lessons that cover the most interesting and dynamic new features of HTML 5 that are ready to drop into a web development or intro programming course. Each lesson comes with instructor PowerPoint slides, a complete reading assignment with hands-on examples, including the files and assets to use in each assignment. A single lesson has enough content for a 75-100 minute class session, and the hands-on examples are great for either a lab session or homework assignment. The six lessons are: Lesson 1 – Defining HTML 5 Lesson 2 – Fundamentals of HTML 5, XHTML, and CSS Lesson 3 – Introduction to CSS Layout Lesson 4 – Using HTML 5 Markup Lesson 5 – Working with Canvas Lesson 6 – HTML 5 Multi-Media and Drag and Drop This content is available at no charge and can be downloaded from here:

Telerik MVC Grid won't refresh after delete

For a project we are using the Telerik MVC controls. I have to say that I was really pleased with the experience in general, although I had some small issues. One of the problems I had was with the editing feature of the Telerik MVC Grid . Everything appears to work as expected except for the delete. The delete MVC action is called and the row is  deleted from the database but the grid does not refresh. [HttpPost] [GridAction] public ActionResult DeleteCodetable(string codetableType, Codetable codetable) { _codetabelService.Delete(codetable); //Rebind the grid return LoadCodetable(codetableType, refreshCache: true); } It took me some time to find the answer on the forums . The delete action only passes the id of the element to delete to the action method. This causes some model binding validation errors as the Code and Description field are required on my Codetable object. public class Codetable { [Required] public virtual int Id { get; set; } [Required] public virt

Microsoft Product Lifecycle Search

I get a lot of questions about the lifetime and end of support of multiple Microsoft products (especially about one you probably heard of before… Silverlight ). So how do you know how long Microsoft will officially support a product or technology? It’s not a secret. You only have to browse to the Microsoft Product Lifecycle Search Page and search the product or technology. Let’s do the test with Silverlight 5: So now it’s official… Silverlight 5 is dead in 2021. I guess that gives you the time you need to upgrade…

Look up DB2 error codes: the fast way

I have to admit that I’m not a big fan of DB2 although there is not much wrong with the database itself. I have more problems with the far-from-perfect tooling. One of the things that keep annoying me are the cryptic error messages including an even more cryptic SQL error code that DB2 returns. Normally I look up the error code in the DB2 Information Center , but if you need a shorter and faster way to get at least a short explanation of what an error code means, you can use the following SQL query: VALUES SQLERRM(-161) Result: 1 ------------------------------------------------------------------------------------------------------ SQL0161N The resulting row of the insert or update operation does not conform to the view definition.

Team Foundation Server 2010 Power Tools for Eclipse

Visual Studio users already know this for a long time, Microsoft has the Team Foundation Server Power tools . These tools extend the Visual Studio and Team Explorer IDE with lots of extra functionality. Now these features finally become available to Eclipse Developers as Microsoft released the first version of the Team Foundation Server 2010 Power Tools for Eclipse . “A set of Team Foundation Server power tools targeted for Eclipse developers already using Team Explorer Everywhere 2010 with SP1 to talk to TFS. This release brings the ability to be able to sign up for Team Foundation Server alerts directly from Eclipse, to save common work item details into a work item template for quick creation of new work items and to allow searching of files in source control by file name, wildcard or by the developer who has the file checked out.”

Techniques to improve your training feedback: The happiness door

Useful feedback is one the best ways to improve your training skills. But how do you know what people think? Of course you can always ask to fill in a questionnaire but that takes a lot of work, so you probably only do this at the end of your training. But this gives you only a general overview and actually it’s already too late. Wouldn’t it be nice to get feedback during the training and adapt immediately? One feedback technique I’ll give a try during my next training is ‘The Happiness Door’ as described by Jurgen Appelo in this blog post: . Don’t forget to read his tips before trying this technique. The method is very simple. You ask people to give you immediate feedback after a training session. They do this by adding notes to on a wall or door and placing it next to the happiness index (5 = excellent … 1 = bad) they want. People can add empty notes or leave some comments.

Team Foundation Server WorkItem FieldControl Attributes

Probably the easiest way to customize a TFS WorkItem is by using the Process editor, a part of the TFS Power Tools . Using this editor you can add your own work item fields, customize the layout and change the corresponding workflow. Next to the obvious list of settings there are some less known things you can change using the Attributes property. By using these attributes you can add custom attributes to the Work Item XML. Here are some useful attribute samples: NumberFormat (for FieldControl only): Useful if a number value is displayed in the field. Possible values: WholeNumbers, SignedWholeNumbers, DecimalNumbers, SignedDecimalNumbers. Setting this attribute determines what characters are allowed to be entered in this control. MaxLength (for FieldControl only): Maximum length of allowed characters for field control in form UI. Format (for DateTimeControl only): One of values of DateTimePickerFormat enum . Possible values: Long, Short, Time and Custom. Cu

TF215097: An error occurred while initializing a build for build definition: Cannot create unknown type

While creating some custom build activities for TFS Build I ran into this error TF215097: An error occurred while initializing a build for build definition \OrdinaALM\TestBuild: Cannot create unknown type '{clr-namespace=Ordina.CustomActivities;assembly=Ordina.CustomActivities}Ndepend'. I discovered that my solution couldn't be loaded because TFS is looking for a particular attribute to my class. As my custom activity was completely build in XAML I had to use a partial class definition to get the attribute added. namespace Ordina.CustomActivities { [Microsoft.TeamFoundation.Build.Client.BuildActivity(Microsoft.TeamFoundation.Build.Client.HostEnvironmentOption.All)] partial class Ndepend { } }

QFEs and Hotfix Rollup Package for Microsoft Test Manager 2010

If you are using Microsoft Test Manager, this post is for you.

Clean up your development PC

Maybe you didn’t notice it yet, but Visual Studio leaves tons of temporary files all over your hard drive. This is why, over time, your computer loses hard disk space. Same thing for Windows updates, fixes, etc… As I was running out of disk space I was looking for some ways to free some space. I found two very useful links that saved me a lot of disk space: Clean up after Visual Studio Guide to Freeing up Disk Space under Windows 7 Translate localized error messages

If you are working on a non-English OS, you probably have seen it: these localized error messages. Very useful for the end user but very annoying for us developers who want to google or bing for this specific problem. And while searching for an English error message gives you thousands of hits, you only get a few when you use the localized error message as the search term. Last week I got the following tip from a colleague: , a very useful website which allows you to translate your localized error messages back to English. It’s even available as a browser plugin for your favorite browser. A must have for every developer!

TFS Build: Build by label

By Default Team Foundation Build services allows you to build your solutions either based on the latest version available or on a combination of the latest version and a specific shelveset. But what if you want to build a labeled version of your code? You can specify a Label in the GetVersion parameter in the Queue new Build Wizard, going to the Parameters tab (for labels add the “L” prefix):

Integrate NuGet in your build process: TFS NuGetter
