Can i place controls from the properties dialog of an express vi on the front panel?

Question

I'm using the spectral measurements express vi in my vi and I'd like to put the "window" and "number of averages" controls from the properties dialog on the front panel. However, there are not outputs on the express vi icon for these parameters. Can I place controls for these on the front panel somehow or do I always have to go into the block diagram and open the properties dialog to change the values?

Answer 1

The way to do this is to right click on the express VI and select Open Front Panel. This will convert it to a standard subVI. then go into the subVI and replace the Spectrum Averaging and Spectrum Window constants to front panel controls by right click on them. Right click the icon and select Show Connector. Wire the new controls to a free terminal on the connector. You may have to add additional terminals if there aren't any available to wire to the new controls.
