This little app is compatible with most wireless logitech mouse.
It displays small indicator in the system tray showing % charge left as well as if the mouse is currently charging or not.
Double clicking this system tray icon shows a window where you can configure if you want the app to start with Windows. When checked the program will create a shortcut in the startup folder that points to the location of the exe. This will launch the app minimized when Windows is started.
This app depends on a few dlls. Most are included in various c++ runtimes and do not need to be explicitly loaded
however 1 important dll that is required is logi_nethidppio.dll. This dll is bundled in the OnboardMemoryManager executable
which can be downloaded from logitech https://support.logi.com/hc/en-us/articles/360059641133-Onboard-Memory-Manager.
Extract the dll from that exe and place it in the embeddeddlls folder. The project will pack the dll into the assembly as embedded resource.
