Open file dialog on real time target

[jckvt]

Is it possible to load data from a file on a local PC from a VI running on a RT target? I have an NI RIO that the VI is running on. From the front panel I want to be able to click a button and have a file dialog pop up where I can choose a local file to load data from. The problem is that when I try to use the load data from spreadsheet VI it returns an error saying the dialog was cancelled. If I use the file dialog express VI, the VI always returns true for cancelled. The file dialog never appears. Is it not possible to open a local file in a VI running on a real time target?

This function will not work in Real-Time (RT).  Please review KnowledgeBase 2S9D21OH: Creating a File Dialog for Use with LabVIEW Real-Time for additional information on this.  However, this will only locate files on the RT target.  If you are trying to communicate with a file on your Host machine, you will either need to transfer this document to the RT target, or set up different architecture to accommodate this task.  I should also add that having the user define the file source manually creates non-determinism within your system.  Again, this may be another reason to set up a different architecture.
