Print VI Panel or Documentation VI

If a front panel is not visible, LabVIEW does not update the values in the objects on the front panel. If you call a VI whose front panel is not visible and you use the Print VI Panel or Documentation VI to create an image of the front panel, the image does not reflect any value changes that occurred when you ran the VI.

If you want the image to reflect value changes, make sure the front panel is open before any values change. If you do not want to display the front panel but want the image to reflect value changes, create a Property Node from any front panel terminal on the block diagram of the VI for which you want to create a front panel image.

You also can use the Front Panel:Get Image and Get Panel Image Scaled methods to return a front panel image programmatically. Use the VI Documentation VIs to print specific components of VI documentation or to save the components to a report.
