How to disable mousewheel message to CSpinCtrlButton in MFC?

Hi,

I have placed spin control button on my form and made a CEdit widow as a buddy for that Spin control. My parent form has a Vertical scroll bar. Suppose my cursor is on spin control and if i do mouse wheel operation then i don't want to change the value in spin control, instead it should scroll my form window.

I tried overriding WM_MOUSEWHEEL message on CSpinCtrlButton but it seems CSpinCtrlButton  doesn't send WM_MOUSEWHEEL message. I used UDN_DELTAPOS notify message to check some action on CSpinCtrlButton.

Please can some one guide me how to handle mouse wheel operation on spin control? 

Thanks,
