My Countdown application for the Windows Phone 7 is now available in de Windows Phone Marketplace.
Countdown is a metro-styled application that is used to track various dates, events and displays the time remaining until the timer comes to an end. See how long until Christmas, New Year, Easter, Halloween, Thanksgiving, etc. Remember Birthdays, anniversaries, or any other important events.
The Problem
The Windows Phone tools in Visual Studio an Expression Blend let you create a 'Windows
Phone Data Bound Application" (Template). This application uses SampleData
and two List/Detail pages. The List (MainPage) contains a listbox which is templated.
The ItemSource of this listbox is databound to the Items in the SampleData. When
run the application and select an Item in the ListBox the DetailsPage is shown using
navigation. This navigation is initiated from the SelectionChanged event of the
listbox in the MainPage. When you remove this event from the XAML you would expect
that the selected item in the listbox would be shown using the Accent color of your
phone. But this doesn't happen. It took me a while to figure out the reason why, and how to
solve it.
My Sudoku has been accepted in the Windows Phone 7 Marketplace.
Play standard 9x9 grid Sudoku puzzles on your phone. Exercise your visual scanning and processing powers and strengthen your brain. With four difficulty levels, intuitive interface, and all the functions right at your fingertips, this Sudoku app is sure to be your favorite.
I have placed a movie of my Sudoku for the Windows Phone 7 on YouTube. I have build it using the new Beta bits. It uses the same Model and ViewModel code as my Silverlight implementation.
I'm almost finished. I only have to implement the 'Notes' and 'Import from Camera' features. I can't test the Import/OCR yet because the emulator doesn't support the WebCam, bummer. I hope i can test it on a device soon.
Last year I wrote a Sudoku using Silverlight 2. I'm now porting it to the Windows Phone 7. I started designing the UX. I decided to stick to the Metro design. It's really clean.
I'm using the ApplicationBar and Menu. I'm not totally sure which buttons to use. For now: pause, undo, redo and hint. I will have to create a ShakeTrigger which I will use to create a new game. I will have to postpone this until I have a real device to develop on. The accelerometer is hard to emulate.
I'm also planning to 'import' Sudoku's using the phone camera and OCR. But probably not in the first version.
The Windows Phone 7 supports single and multi touch gestures. I have implemented the Tap, Double Tap and the Touch&Hold gestures using Triggers. You can use them to trigger an Action in Expression Blend.
You first have to reference the GestureTriggersLibrary. Then you add an Action to a control using the Behavior assets. Finally you change the TriggerType using the New button.
The following example has tree TextBlock controls on with a ChangePropertyAction attached to it. This action sets the Text of the red TextBlock (textBlockResult) using the Tap, Double Tap or Touch and Hold GestureTriggers.
Yesterday I attended the Windows Phone 7 Developer Hub. The quality of the sessions was very good. They had some phone prototypes which you could play with during the breaks. I had the chance to play with an LG Windows Phone! It looks and feels great. I can't wait to get one!
It really inspired me to develop a new training for it together with my friend Loek. We plan to finish the training by the time Microsoft releases the first builds which we can run on real phones.
The content of the training will be:

Graphics and Animations: Shapes, Brushes, PixelShader Effects, Resources, Transformations, Animations and storyboards, Key frames and Interpolation, Triggering and Programming Animations Methods, Tips & Tricks
UI Customization: Styling, Skinning (Templating), Styling and Skinning, Template Binding, Visual State Manager (VSM), Tips & Tricks
Data Binding: Element To Element Binding, StaticResource Binding, DataContext Binding, Binding to Collections, Blend Sample Data, MVVM, Converters, Data Validation, Data Annotations DataBinding from Code, DataGrid, Tips & Tricks
Programmability: Using and creating Actions/Triggers/Behaviors and Commands. Using Files, Base Class Library, Asynchronous Programming, Sound, Accelerometer, Location Service
Control Creation: Creating User Controls, Dependency and Attached Properties, States, Creating Templated Controls, Transition Effects, Tips & Tricks
I have written a Silverlight Minesweepe game in October 2008. I just published an improved version on Silver Arcade which support right mouse click. I implemented it using the following RightMouseTrigger. You can set the SetHandled property to true. This stops the MouseRightButtonDown event from bubbling to it's parent.
I really love Behaviors, Actions and Triggers. I hope you like it too.
Zoals beloofd kan je de Presentatie + Demo's van mijn 'Introduction to WCF RIA Services' sessie van de DevDays downloaden. Je dient eerst wel de Northwind database te installeren op localhost\SQLEXPRESS. Het benodigde installatiescript is ook in de ZIP file opgenomen.
Met dit formulier kunt u informatie over een In-Company of Small-Group training aanvragen. U kunt in het bericht aangeven welke training u wilt, voor hoeveel personen, wanneer deze verzorgd moet worden en op welke locatie. Wij nemen vervolgens contact met u op.
