srq: 204233 hello, "GetVIReference()" is a method of LabVIEW ActiveX. It returns a reference to a LabVIEW-VI; The VI object oVI has several methods;
one of these methods is "call2" which calls the VI and you can pass some parameters to it, as mentioned in the comment. If you browse the LabVIEW help and search for "ActiveX, VI class methods", you will find further information. regards, Robert H. National Instruments
