At any one time, we have several complex LabVIEW-RT projects that run behavior experiments for us, taking multiple channels of analog and digital data while providing a complex series of audio and visual stimuli. For each project, there is an RT part that "runs" the Experiment and a tailored Host part that runs the UI, handles an Excel Workbook that specifies the various trials being performed, displays the data, and saves the sampled results to disk.
Each of these projects are developed using LabVIEW Project, and each LV Project has its own, unique name. When we build UI and RT executables, we would like an "automatic" way to associate them with each other. A "natural" way would be to use the "shared" information of their joint Project. There are ways to get the Project name in the Host UI code, both in Development mode and from an Executable.
I would like to propose that NI provide a Property or something similar for the RT side so that the RT code, at Run Time, could determine the Project from which it came. With both sets of code knowing their shared "ancestor", they could use this information to ensure they are talking to their proper counterpart. They could also use it to "mark" data structures (such as Files or Folders) that belong to them. For example, there could be multiple configuration files, one for each Project, but they could be uniquely identified as "<Project> Config.xml" (where "<Project>" is the name of the Project containing the VI, allowing the appropriate Configuration file to unambiguously be chosen at Run Time).
