This example uses the My.Computer.Mouse.WheelExists and My.Computer.Mouse.WheelScrollLines properties to determine if the mouse has a scroll wheel and how much to scroll when it rotates.

If My.Computer.Mouse.WheelExists Then
    Dim lines As Integer = My.Computer.Mouse.WheelScrollLines
    If lines > 0 Then
        MsgBox("Application scrolls " & 
            lines & " line(s) for each wheel turn.")
    Else
        MsgBox("Application scrolls " &
