问题 We can’t just leave our customers that are not able to upgrade to windows 8 for a long time in the larch. However there is demand for a “tablet”/”touch” version of our app. So how can we support both touch with Metro on Windows 8 and our current customers from a single code base? When WPF come out, after a lot of “Pushing” Microsoft saw since and make it work on Windows XP – has anything like this been talked about for WinRT. (I am not expecting any solution to work on XP, as XP support is

问题 Say I have an async method which saves to file: async Task SaveToFileAsync() { var file = await folder.GetFileAsync ( ...) var stream = file.OpenFileAsync(...) ///etc } Now imagine that SaveToFileAsync is called twice simultaneously. This is a problem because you can't write on the same file simultaneously If this were a regular method, lock() would fix this: void SaveToFile() { lock(something) { /// code here } } However, lock is not allowed in an async method. Of course, one could call

问题 While developing UWP application I recently found quite a few memory leaks preventing my pages from being collected by GC. I have a ContentPresenter on my page like: <ContentControl Grid.Column="0" Grid.Row="1" Content="{x:Bind ViewModel.Schedule, Mode=OneWay}"> </ContentControl> After I remove the Content, or replace it with dynamic {Binding} -- page is collected when I navigate from it. Otherwise it remains in memory. Is it bug or I'm doing something wrong? Is there a way to release and

问题 Is there any mechanism to identify a device uniquely (even if it is anonymous)? To be clear, by "device" I mean the computer/slate/pc. Windows 8.x http://codepaste.net/ybt893 string HardwareId() { var token = Windows.System.Profile.HardwareIdentification.GetPackageSpecificToken(null); var hardwareId = token.Id; var dataReader = Windows.Storage.Streams.DataReader.FromBuffer(hardwareId); var bytes = new byte[hardwareId.Length]; dataReader.ReadBytes(bytes); return BitConverter.ToString(bytes); }

问题 I am storing the state of my data model. I clone the data model and then want to have it written to "disk" asynchronously. Should I be using Task.Run() which runs it on a background thread? Or should I just make it an async function and not await on it? (this will make it run on the UI thread) Similar stuff to this, but my question is a bit different: async Task.Run with MVVM And what is the criteria to decide which to choose? Thanks! 回答1: You should use Task.Run for CPU-based work that you

问题 I am making a Javascript Windows 8 app in which the user connects to my server and logs in. Currently, I am trying to use the XmlHttpRequest Object to do so (specifically, WinJS.xhr) but when I get the output of getAllResponseHeaders(), the Set-Cookie header isn't there (because it is an Http-only cookie). Is there any way to get http-only cookies from a JS Windows 8 app? All help is greatly appreciated and I always accept an answer! 回答1: As it turns out, Windows 8 apps are already able to

问题 I'm using a ListView with a Custom Template, something like this: <ListView.ItemTemplate> <DataTemplate> <Grid HorizontalAlignment="Center" Width="220" Height="220"> <Image x:Name="image" Stretch="UniformToFill" Source="{Binding Brand.Image, ConverterParameter=transparent, Converter={StaticResource LogoToUriConverter}}"/> <StackPanel VerticalAlignment="Bottom"> <TextBlock Text="{Binding Name}" Foreground="{StaticResource ApplicationColor}" Style="{StaticResource TitleTextStyle}" Height="30"

问题 In earlier Versions of .net you could use something like ICollectionView collectionView = CollectionViewSource.GetDefaultView(AllImages); To build up filter mechanisms for UI-Elements. But this doesn't seem to exist in WinRT anymore. I'm using a ListBox-Element to display an User-List. The User-Class contains the properties username (String), isOnline (Boolean), isFriend (Boolean) and unreadMails (Int). I need some kind of Filtering and sorting. Filter by: no Filter only isOnline == true
