warning after adding event handler

[geerligs]

I found that when adding the proposed event handler, I get a warning:
Warning C4100 'e': unreferenced formal parameter BlankApp1 c:\Users\han\source\repos\BlankApp1\BlankApp1\MainPage.cpp 27
Warning C4100 'sender': unreferenced formal parameter BlankApp1 C:\Users\han\source\repos\BlankApp1\BlankApp1\MainPage.cpp 26

I'd not expect warnings in a demo program.

Is there any way to circumvent these warnings?
