问题 i am trying to read bpm embedded in mp3 file like this one : i have tried using Windows.Storage.FileProperties.MusicProperties but it only contains title, singer, etc. it can't read the bpm i showed before. im looking into https://taglib.github.io/ they seems not having such function too. is there any workaround to this? 回答1: When you've loaded your music file into a StorageFile, you'll want to place a similar call in your code like this: var fileProps = await file.Properties

问题 I've seen that I can capture the microphone and sound-files with elements in the Windows.Media.Audio namespace. I'm looking to capture the speaker output , though. For example, I click on something and the system sounds the alert sound - I want to be able to capture that. Is there any way of doing that using elements in Windows.Media.Audio (instead of going more low level into Win32 calls)? 回答1: Well, even with "low level Win32 calls", you can't do any loopback recording in UWP.

I feel like it is probably obvious but I am not seeing it! 回答1: You will have to contact an external server. Even if the platform

My solution builds with zero errors. However, I receive an error after I create an app package and run the Windows Application Certification Kit. I have added and removed references to the C++

问题 I've spent hours trying to understand what is happening here. I have a RichEditBox that the user can interact with by tapping on it and using the keyboard or by tapping on a couple of buttons that add some characters inside the RichEditBox. This is a method I use: private void ptrPlus_click(object sender, RoutedEventArgs e) { try { myRichEditBox.Document.Selection.Text = ">"; myRichEditBox.Document.Selection.SetRange(this.Document.Selection.StartPosition + 1, this.Document.Selection

问题 On Windows 10, can a UWP be launched as a screensaver? If so, how do you register your app with the OS such that it gets listed in the screensaver dialog? (Windows 8 store apps cannot be screensavers. I cannot find any information on UWPs) 回答1: I am very sorry to disappoint you, but no, you can not set your UWP app as a screensaver provider. What you could do instead is offering the user to give your app control of the lock screen or wallpaper image. UWP apps are able to set these images even

问题 If it is, how can I use it to develop something in-house? I don't want it on the store. It should never be seen outside of the Enterprise. Edit: Is sideloading the only way? 回答1: I don't want it on the store. It should never be seen outside of the Enterprise.
