问题 The above exception occurs at line await bitmapImage.SetSourceAsync(fileStream); whenever I tried to retrieve image from local file. This is the method I'm using for storing and retrieving the image file. public async Task<BitmapImage> RetrieveImageFromFile(String fileName) { try { StorageFile localFile = await _storageFolder.GetFileAsync(fileName + "Img"); BitmapImage bitmapImage = new BitmapImage(); using (IRandomAccessStream fileStream = await localFile.OpenAsync(FileAccessMode.Read)) {

问题 From the docs: Note When a user flips through FlipView content using touch interaction, a SelectionChanged event occurs only when touch manipulations are complete. This means that when a user flips through content quickly, individual SelectionChanged events are not always generated for every item because the manipulation is still occurring. Is there a way to configure the FlipView control to fire SelectionChanged for each flip? This behavior makes implementing paging interesting as the user,

问题 So when I was watching this video from BUILD I thought it's gonna be easy... But I can't seem to get the tile of my WP Silverlight 8.1 app to change by doing the following. const string xml = "<tile>" + "<visual>" + "<binding template='TileSquareText01'>" + "<text id='1'>testing 123</text>" + "</binding> " + "</visual>" + "</tile>"; var xmlDoc = new XmlDocument(); xmlDoc.LoadXml(xml); var tileNotification = new TileNotification(xmlDoc); TileUpdateManager.CreateTileUpdaterForApplication()

问题 I implemented in-app purchases inside universal app and for testing I use my own XML file with list of in-app products. On Windows 8.1 it works very well but on Windows Phone 8.1 FormattedPrice property is returning price with many decimal places. Am I able to somehow fix it because it looks really strange? Sample: http://1drv.ms/1yVNhRw <Product ProductId="product2" ProductType="Consumable"> <MarketData xml:lang="de-de"> <Name>Product Title 2</Name> <Price>49.99</Price> <CurrencySymbol>€<

问题 Im developing an windows phone 8.1 app. I have used shared app bar across the pages. At some point of time, I need to change the label or the icon of the global app bar.

If you want to change for example a Label ( Icon or anything else), you should be able to do it like this: // change the label of the first button (

问题 There are some odd ways, like checking for pair devices and catching exceptions to see it if is on or not. if ((uint)ex.HResult == 0x8007048F) { var result = MessageBox.Show("Bluetooth is turned off.\nTo see the current Bluetooth settings tap 'ok'", "Bluetooth Off", MessageBoxButton.OKCancel); } But I see there is a new BluetoothConnectionStatus api but don't know how to use it. How to check bluetooth status in Windows Phone Runtime apps? 回答1: It's probably something like this: using Windows

问题 I'm trying to disable Windows Phone runtime's default page navigation animation. All I could achieve, is to change it to either continuum, turnstile or slide, but I'd like the page to change instantaneously. So when I call this.Frame.navigate() it should navigate to the new page without any animation. In Silverlight, this was the default case, no page transitions out of the box. Now I can't get rid of them. The reason why I am trying to accomplish this, is because I'd like to add my own
