问题 In my Windows Phone 8.1 app I'm creating a CustomPage and then navigating to it, all in code behind. My CustomPage class is: using Windows.UI.Xaml.Controls; namespace TestApp { public class CustomPage : Page { public CustomPage() { this.BuildPage(); } private void BuildPage() { var panel = new StackPanel(); panel.Children.Add(new TextBlock { Text = "Hello World" }); this.Content = panel; } } } And then in my MainPage.xaml.cs I'm doing this: CustomPage myNewPage = new CustomPage(); Frame

问题 How do I convert an object of BitmapImage type to a byte array? There's plenty of examples out on the web but all of them are using methods that no longer exist for windows Store app. best solution I've found is this, however I get an exception on the first code line when trying to run it public static byte[] ConvertBitmapToByteArrayAsync(WriteableBitmap bitmap) { using (var stream = bitmap.PixelBuffer.AsStream()) { MemoryStream memoryStream = new MemoryStream(); stream.CopyTo(memoryStream);

问题 I have a listview(for snapped state) and a gridview(for normal state) in my app page (which is an items page template ) and they are both bound to a collection that implements ISupportIncrementalLoading interface. Here are the implemented methods: public HasMoreItemsDelegate MoreItemsExist { get; set; } public LoadMoreItemsDelegate<T> ItemsLoadAsync { get; set; } public bool HasMoreItems { get { return this.MoreItemsExist(); } } private bool isLoading; public bool IsLoading { get { return

问题 I am quite new to MVVM, so sorry for probably simple question. However, I can not understand which mechanism from MVVVM (I am using MVVMLight if that is of any consequence) to use in order to program the simple following scenario: I have textbox TB, where user can fill in URL. Than I have a button B and webview WV. If user clicks on button, the app should take the text from TB and display it in the WV. I knwo that I can create a property in viewmodel and bound it to TB.Text. I understand

问题 I want to Convert a string DashBoard to a type of page named as DashBoard because I wanted to use it in navigation purpose. Normally I navigate to some page like this this.Frame.Navigate(typeof(DashBoard)); but I want to DashBoard page to be replaced by variable like this this.Frame.Navigate(typeof(Somestring)); 回答1: You could use the Type.GetType(string) [MSDN] this.Frame.Navigate(Type.GetType(My.NameSpace.App.DashBoard,MyAssembly)); Read the remarks section on how to format the string.

问题 I've seen both this and this — same problem, different question. I'm trying to connect my Windows 8.1 Store app to an ASP.NET Web API web service, secured over HTTPS using a self-signed certificate. It's a proof-of-concept application that will end up on < 5 different machines and seen only internally, so I was planning to just install the certificate as trusted on each of the target machines. When I try this on my development setup, both HttpClient APIs fail to establish the trust

问题 I am planning to realize apps to be used from Surface Win8 new tablet. Will it be necessary to pass from the new Windows App Store (as it happens for iOS) or will I be able to distribute the .exe without passing from Microsoft? 回答1: As far as I aquired information.
