CVI UI Panel updating from TestStand

[jsmalley]

I'm experimenting with using a CVI graph strip chart in TestStand(4.0).   I'm new to threading in TestStand. I would like to do two simple things at first:

1.Load the CVI UI graph panel

2. Update the graph attributes.

Attached is a solution that uses a separate thread for running the CVI GUI and the main thread for updating the title,axis names and data . For some reason, I seem have to have a generic wait to allow the separate thread to update the seqcontext (FileGlobals being updated in TS). If I don't wait, the FileGlobals have not been updated yet, so the UpdateGraph function fails.

Is there anything besides a blanket wait statement that I can use to know when the separate thread has updated the FileGlobals so that I can continue with my UpdateGraph function? I thought about a loop/timeout function, but I thought maybe there was some other thread/synch mechanism that I missed.

Hey jsmalley,

A Wait step is definitely a good and simple solution to your challenge, however, you could also try taking a look at some of the other TestStand Synchronization steps, which are often used when multithreading.  Documentation on these steps can be found on your machine by browsing to Start»Programs»National Instruments»TestStand»Online Help»Manuals»TestStand Reference Manual.  The documentation I'm referring to can be found in Appendix B of this document.

Furthermore, there should be some synchronization examples found on your machine at <TestStand>\Examples\Synchronization.

I hope this helps!
