Creating a Mouse Wheel Event

Post by jasony00 »

Hey all,

I am need to create an event to use my mouse wheel. At this point, while the mouse is over a form, I just want to be able to detect when the mouse wheel is moving.

Thank you,
Jason

I believe that you will find that the mouse wheel events are only tracked by the scrollbar control in standard forms.

Thank you,

PowerShell Code
Double-click the code block to select all.
$mousewheel = {
     $m = [System.Windows.Forms.MouseEventArgs]$_
     # number of relative units to move (+/-)
     $m.Delta
}
$listbox1.add_MouseWheel($mousewheel)
