Hello reddys, No, unfortunately this is not possible. Parameters are always passed byvalue to VI Inputs. If you are using the VI-object method SetControlValue(controlName, value) the controlName is the string Name of the front panel control. The value variant has to be numeric, Boolean, string, or array. A cluster in LabVIEW is represented as an array of variants in ActiveX.
The same is true for the Call method - with the only difference that you have to pass an array of Control names and an array of values to that function. It seems that LabVIEW internally accesses this array with pointers to get and set the different values. Ingo Schumacher National Instruments
