centered run-time position not working

PaulG. — Fri, 10 Sep 2010 12:43:01 GMT

My app calls numerous sub-vi's that message the user, require input/output from the user, take the user to different functions, yada yada. All are set with run-time position centered. Some, but not all, simply will not run in the center and appear up and to the left of center. What did I miss? Thanks in advance.

Open the application builder and double check Source File Settings >> Customize VI Properties. Sometimes (I think this is a LV bug), it is necessary to enable/disable the checkbox on the left of Window run-time position in order to really update the selected position.

Very often, after closing/reopening the VI Properties dialog box for a VI, the position was reset back to Unchanged even though I set it to Centered. I'm now used to enable/disable the checkbox after setting the position... and the problem disappeared !

That didn't work either. This is annoying. And it looks REALLY REALLY BAD. Stupid software can keep all FP's centered ... except for one.

Hello,

If you are having trouble getting things to work either through the Applicatin Builder VI Properties or through the VI's own VI Properties, you can explicitly call the Front Panel Center method at the initialization state of your code. This is documented here: http://zone.ni.com/reference/en-XX/help/371361G-01/lvprop/vi_fp_run_time_poscntred/

I had a DOH! moment over the weekend and remembered I could do this. I can't believe I had forgotten about this method.
