hi,

use the numeric2's value properties, actually as same as you did use numeric's1's property.

also see some more advance mouse wheel events here.

can not use the same logic for the second numeric control as i am not able to get out of while loop

hi,

I dont know in LV2009(I use 2014) but there is no logic needed, just hover on the control and scroll it will increment and decrement.

if you cant do this in 2009 then use property node of control called "Built-it Mouse Wheel Support " and use case statement.

Native mouse wheel support didn't come until LabVIEW 2013.  Until then it was very difficult to get mouse wheel events easily.  Some involved .Net, or Windows DLL calls with event call back VIs.  I remember this technique even having issues on 64 bit Windows.

                              no option for built-in mouse wheel support in 2009

Hi,

then use Bound and Postion property get cordinates and respective control refrence

I made attached eample, currently only works for numeric (or sepcifically Digtial class controls) , you can modify it for different controls
