 To send an integer number to some counter, use this:
 
     SendMessage((HWND)655890, WM_USER, i, n);
 
-Here `i` is a counter index and `n` is the number you want to see in it. 655890 - is the handle of a counter's window. It is written on top of it and also accessible via clipboard. Just click the "W" button to copy the handler, or "C" button to copy a whole SendMessage string.
