问题 I decided to build a tool to display the battery level of a pair of Bluetooth headphones, since I got this feature on Android, but not on Windows. For some reason, it just doesn't display in the settings. I'm using UWP and with the Device Enumerator I managed to pull a list of connected devices. Is there any way to get the battery level from this point? I've seen that people are using RFCom or GATT, but their issue involves connecting to the device, which I think is redundant since the tool

问题 Ok, I have a simple and silly question, maybe someone could clarify for me. In the instructions provided by Microsoft, they state "1.In your project, locate a section of code that runs during startup in which you can register your app to receive Dev Center notifications." Now, would this be in App.xaml.cs OR in MainPage.xaml.cs I did my work in App.xaml.cs (Correct Place) However, it is not working The instructions provided by Microsoft were vague. The example they provide also gives no hint

问题 I have a C++/WinRT/UWP project. I need the HWND and HINSTANCE to be able to correctly initialize Direct Input, otherwise DirectInput manage only to enumerate the keyboard and mouse but not the joysticks.. don't ask me why, I even tried to get the TopMostWindow from the HInstance got with GetModule, it just return NULL when running from my C++/WinRT/UWP app, but works when running from a console app. documentation https://docs.microsoft.com/en-us/windows/win32/api/corewindow/nn-corewindow

问题 I'm decoding a H264 video stream using Media Foundation. It works, but performance is really poor on both Windows (desktop) and HoloLens 2 (UWP). Decoding a single 1920x1080 frame takes 30 ms on a fairly powerful PC, 100 ms on the HoloLens . I'm wondering if it's using software rendering instead of hardware rendering. Any idea on how to make sure that I'm doing hardware decoding, or any other hints on how to improve performance? The code is as follows: Decode.cpp: #include "MFUtility.h"
