Description

Executes each time you roll the mouse wheel.

MouseWheel has the following parameters:

Shift determines the state of the CTRL, ALT, and SHIFT keys at the moment you released the mouse button.
WheelDelta indicates the distance the wheel was rotated. WheelDelta is positive if the mouse was rotated upward, and negative if the mouse was rotated downward.
Handled specifies whether this form handles the mouse wheel, or other child controls do this.
