Hi, I understand that you need information relating to variant input variables in LV 7.0 with a focus on reference numbers. There are several resources (knowledge bases and tutorials) on ni.com that may help you:
Typecasting ActiveX refnums in LV: http://digital.ni.com/public.nsf/websearch/EFA054B18887779386256998004E456C?OpenDocument Converting ActiveX variant data types: http://digital.ni.com/public.nsf/websearch/CC1BE7AC3B5710F7862565BC006DE644?OpenDocument General ActiveX/LV tutorial: http://zone.ni.com/devzone/conceptd.nsf/webmain/5401BE584FBAEECE862567C2006D36C7?opendocument The refnum to variant functionality should be backwards compatible for LV7.0. If the above resourses don't help, or I haven't addressed your issue as you expected, please let me know. Thanks for contacting NI! Marcus G. National Instruments
