问题 I'm starting to learn application development trying to implement an application in UWP (Universal Windows Platform) that opens an Excel file to show its data to the user, since I have an idea that would require this feature. However, following a WPF (Windows Presentation Foundation) tutorial to do the same thing I've run into an exception when I try to open the Excel application through code, probably due to some devices on the UWP set not supporting Excel (?). I'm wondering if there is some

问题 I have an UWP project with SQLite database stored locally. The app is going to be used by multiple users and I am writing a Client app. Client app should pull data from users database. Is there a way to achieve this without leaving SQLite behind? I really like what I learned about how the SQLite works and would not like to just bin all the work I did. Is it possible to do something like uploading users' data to the server and then retrieve it using client app? Something like uploading the

问题 I am currently trying to develop a speech synthesis UWP DLL using the namespace Windows::Media::SpeechSynthesis. I read this documentation and the Microsoft page dedicated to the namespace.

问题 How do I programmatically check if an UWP app has camera access? I'm trying to do an if check to display some help text if the user has denied access to the camera. I'm trying to get access to it in Unity through Application.HasUserAuthorization, but that doesn't seem to give the right result (eg, it returns true even when you deny access) 回答1: How do I programmatically check if an UWP app has camera access?

问题 As of this writing, the upcoming Prism.Windows 7.1.0 from MyGet Package is missing override method CreateShell() and I really wonder if it's gonna be moved into another method or it'll be gone in the final release. If so, what's the alternative solution to implement shell view, assuming the code is from this tutorial and DryIoC container is used instead. 回答1: Rather than using the CreateShell() override, you could create the NavigationService inside of a NavigationView . The code provided in

问题 I've already read and researched all over the net including here: Windows Universal Apps: Call python method from C# [closed] And I understand that UWP is a sandbox and can't open other processes. Nonetheless, I got no other choice but to use python API inside UWP app. The answer in the link above is not clear enough for me and I hope to get any solution, even if it's not a direct one. Of course I tried IronPython which is not working. And Process/ProcessInfo which brigs-up "access denied".

问题 I have a problem with my API, the GET, POST, DELETE and PUT work perfectly. but if for some reason at the time of making a PUT or a POST I generate errors (404, 400, 500, etc) and it is normal that in some times for any query I generate errors ... the problem is that the next Once I go back to do a POST or PUT (being aware that it is ok) the error is stored and it does not let me make the new query ... I do not know what to do or what is wrong. but the GET is still working THIS IS THE

问题 I have a problem when I having my UWP development.In my application, I need to get all the apps details(including its displayname or the ExecutableFileName), which is running in the computer. My first solution is to to use the System.Process class, and I do it like private void Mybutton_Click(object sender, RoutedEventArgs e) { var apps = Process.GetProcesses(); ... } But it is not availbale in the UWP and throws a exception when I try to do it. Secondly,I have tried the System.AppDiagnostics
