Windows Phone 7: Building a simple dictionary web client
Like I mentioned in this post a while back, I came across a dictionary web service called Aonaware that serves up word definitions from various dictionaries and is really easy to use. The services page on their website, http://services.aonaware.co... lists all the operations that are supported by the dictionary service. Here they are, Word Dictionary Web Service The following operations are supported. For a formal definition, please review the Service Description. Define ......

Windows Phone 7 : Dragging and flicking UI controls
Who would want to flick and drag UI controls!? There might not be many use cases but I think some concepts here are worthy of a post. So we will create a simple silverlight application for windows phone 7, containing a canvas element on which we’ll place a button control and an image and then, as the title says, drag and flick the controls. Here’s Mainpage.xaml, <Grid x:Name="LayoutRoot" Background="Transparent"> <Grid.RowDefinitions> <RowDefinition Height="Auto"/> <RowDefinition ......

Windows Phone 7 : UI Control Boundaries
I was working on an application at work when I needed to figure out a really trivial case, well, trivial in theory at least. All I wanted to know was if a button was completely inside a rectangle. Could anything else be simpler you think. Just check the button bounds against the rectangle bounds, pseudocode if (Button.Top > Rectangle.Top && Button.Left > Rectangle.Left && Button.Right < Rectangle.Right && Button.Bottom < Rectangle.Bottom) { //Button is inside rectangle ......

Shake detection on HTC HD2
In the previous post I mentioned that the acceleration vector or the force vector can be used to detect gestures like shake. Here is a crude implementation of shake detection, private const double SHAKE_THRESHOLD = 5.0f; private bool IsShakeDetected(HTCSensorData sensorData) { bool isShake = false; double x = (double)sensorData.tiltX / 1000; double y = (double)sensorData.tiltY / 1000; double z = (double)sensorData.tiltZ / 1000; double forceSqrd = x * x + y * y + z * z; System.Console.WriteLine("F... ......

Applications: Creating a simple UI application for Windows Mobile 6 using Visual Studio 2005: Part 3
So now our program displays the system width and height in a Message box. Let us see how this message box evolves into a Dialog box. Instead of displaying the system metrics in a Message box, we will display the same information in a full screen dialog box. The dialog box will have a menu bar, with the left soft key as "Back" and the right soft key as "Refresh". We'll see what "Refresh" will do later. First lets add the dialog box resource to our project. You can add a new dialog using the resource ......
