Interesting question Clay!
I have never done it from outisde of LabVIEW but ActiveX maybe the ticket.
LabVIEW serves upits front panel controls and indicators. You may be able to get at them as variants by reading from;
LabVIEW>>>FrontPanel>>>Controls
will return an array of ActiveX references to all of the Controls and indicators.
Read the "Label" Property of of each of these refferences to get the name of each control. Search through this list for the control or indicator you wnat to access. Then you can use the property node called "Value" to get the value you are after as a variant.
I have never done this thing myself in C++ but I was able you look at the VBA examples to use navigate PowerPoint from LabVIEW, so in theory you should be able to do the
same thing backwards.
Just my thought, hope it helps,
Ben
