Answer 1

You can use this code.

 [DllImport("user32.dll")]
        private static extern void mouse_event(uint dwFlags, uint dx, uint dy, uint dwData, int dwExtraInfo);

It create method mouse_event in class. Then just use this method.

uint perSent = 10;
mouse_event(0x0800, 0,0,perSent ,0);//it will zoom 10 per sent 

If you want understand more, check this: https://www.pinvoke.net/default.aspx/user32.mouse_event or just google mouseeventflags and use mouse_event.
