Hi Amperage,
Unfortunately it is not possible to do ActiveX calls under LV RT 7.0 or before, or even later(except if MS comes with a tremendous OS running as a real time OS...)
In fact what is happening is that ActiveX is a way to "speak" between programs in the Windows environment(the ActiveX possibilities have to be registred in Windows). So those functions are not only unavailable in LV7 RT but also for mac, linux, sun/solaris, palm os, or even FPGA (No idea for windows pocket PC).
For the CIN , you can type this sentence in the search...it should lead you to some more explanation :
"Can I use CINs and DLLs with LabVIEW Real-Time (RT)?"
I hope this helps (to understand...).
