Hello Heinrich, <a href="http://exchange.ni.com/servlet/ProcessRequest?RHIVEID=101&RNAME=ViewQuestion&HOID=506500000008000000989C0000&ECategory=LabVIEW.LabVIEW+General";>Here</a> is a link to a previous thread discussing typedefs and type descriptors that might help you.
I am still a little confused about what you are trying to accomplish. If possible, could you provide some more details about the behavior of the controls that you want? Thanks! Jeremy L National Instruments
