You define user-specific controls by right-clicking a control and choosing ''Advanced/Customize''. This opens the [[control editor]], where you can change the control.
See [[Control]].


'''Attention!''' Creating a control on a VI's [[Frontpanel]] [FP] from a specified *.ctl file copies this control into the FP, but does not maintain a link to the *.ctl file. Any changes applied to the *.ctl afterwards are not propagated to the VIs FP. Use [[Type Definition]]s instead if you need to maintain consistancy between different control instances.

The CTL File Extension (*.ctl), or Control, is the file extension of LabVIEW controls or type definitions. Controls are stored either in their parent VI or in these dedicated files. When created in a .ctl file the control can be customized and be assigned special behavior: Type Definition or Strict Type Definition.

See Control.
