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.
The current version of OnboardMemoryManager this links against is 2.6.1749. For version 2.1.7479 checkout commit e1711215804c392eaef1dfe7f6559cabac54003e.
