Anyone know what Windows Messages are for the forward and backward mouse buttons, for example I know how to get the mouse wheel...
Code:
    If Msg = WM_MOUSEWHEEL Then
	 Rotation = wParam / 65536
    End If
... but not sure what the code would be for forward and backward buttons (on mouse button up),

So far I've got this but not sure its correct or not. ?
Code:
        
    If Msg = 524 Then '&H20C
        If wParam = 131072 Then '&H20000
            ForwardButtonUp = True
        ElseIf wParam = 65536 Then '&H10000
            BackwardButtonUp = True
        End If
    End If
