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 " & (-lines) & " page(s) for each wheel turn.") End If Else MsgBox("Mouse has no scroll wheel.") End If
