Do we need to worry about overflow here?

mouseData is a DWORD
WHEEL_DELTA is 120
dx is typically 1 or -1 (I've never seen other values).

So I don't think it's worth worrying about.

       wheel.mi.dwFlags = MOUSEEVENTF_HWHEEL;
       SendInput(1, &wheel, sizeof(INPUT));
     }
     if (dy != 0) {
-      wheel.mi.mouseData = dy;
+      wheel.mi.mouseData = dy * WHEEL_DELTA;
       wheel.mi.dwFlags = MOUSEEVENTF_WHEEL;
       SendInput(1, &wheel, sizeof(INPUT));
     }
