Delta as Long | A long expression that specifies the direction and the quantity that the mouse wheel has been rolled. For instance, 1 indicates that the user rolls the mouse wheel up, -1 indicates that the user rolls the mouse wheel down. Any other value may indicate that the mouse wheel has been rolled quicker. |
You can use any of the following properties to update the layer:
The Change event occurs when the layer's value is changed.
