问题 I'm developing a universal app. I have a list of icons in the manifest. The icon on the taskbar is fine, transparency works. The start menu icon doesn't have transparent edges. No edges. The list of icons that I have. How would I make the edges transparent? Should I add any other icons? 回答1: This is by design as the background (behind the tile itself) may be colored quite differently. In the start menu, there's a dark background whereas there's a white background in the Cortana search. Maybe

问题 I'm trying to convert my Win32 app from its MSI into UWP appx package using Desktop App Converter, so that I can update it in the Windows Store. Here's the steps. When I downloaded the Windows_BaseImage_DAC_17134.wim file and tried to install it, I got this at the end (I'm not sure if it means anything): Here's the same as a text: VERBOSE: Removing any pre-existing NAT network Get-NetNat : Invalid class At C:\Program Files\WindowsApps\Microsoft.DesktopAppConverter_2.1.1.0_x64__8wekyb3d8bbwe

问题 My code is namespace classlibrary { public class numerictext : EditText { //My code } When I try to inherit a edit text control in a class library, I'm getting the error: Parent does not contain a constructor that takes 0 arguments. I understand the problem is that Parent has no constructor with 0 arguments. But how to inherit a control in a class library? 回答1: You need to call one of the base constructors in your derived class.

问题 I am trying to allow to register only numbers in TextBox, C# UWP XAML and i dont have the KeyPress Event what should i do? The WinForms equivalent of what I want to do is this: private void txtbox1_KeyPress(object sender, KeyPressEventArgs e) { if (!char.IsControl(e.KeyChar) && !char.IsDigit(e.KeyChar)) { e.Handled = true; } } 回答1: You can use KeyDown and KeyUp events.

问题 Using the below code I am able to get the list of all signed in users. Is there a way to know which is the current active user? IReadOnlyList<User> users = await Windows.System.User.FindAllAsync(); 回答1: I recently ran into this problem myself, and posted about it here. Someone responded there, and gave me some pretty big hints, which in turn helped me to get this solved. Here is the quick and dirty (my UWP is HTML/JavaScript based BTW): First, include the WinJS library in your project, if you

问题 Is there a solution that will allow me to run and test the application life cycle on a physical device? Without the use of "Lifecycle Events" built-in Visual Studio 2015?

问题 I am trying to use an UWP app service to provide some non-UI processing service to other app including the host app . For responsiveness, I want to return the result progressively. Think about grep -ping a folder for files containing a certain string: It would be better to report the files as we found it instead of reporting everything at the end. So my question is: Can this scenario be achieved with the current UWP technology? (I think it is probably possible via polling using the multiple
