Today's nugget deals with gracefully closing a LabVIEW built EXE window. Most everybody knows the trick of using the Quit LabVIEW function at the end of a built EXE to close its window. In fact, you may have even included some extra logic, like with a Conditional Disable Structure or the App.Kind property, to make sure Quit LabVIEW doesn't run while you're developing and debugging your VI in the LabVIEW editor: Have you ever noticed, though, that sometimes when you quit a LabVIEW built EXE, you see a brief flicker of the toolbar? This can happen if you have your VI set to have a dialog window appearance (so that there is no toolbar), and you run the Quit LabVIEW function after clicking the "Stop" or "Exit" button that you created on your VI's front panel. In this case, the built EXE, upon going idle, will show a toolbar (with the Run button) for an instant before the panel closes. To avoid this toolbar flicker, you can make one simple change to the code above: By calling FP.Close, you are telling LabVIEW to hide the front panel of the VI/EXE first before exiting. This way the extra cleanup that LabVIEW must do can occur without the front panel of the built EXE showing, and we never see the toolbar flicker.

FP.Close should be sufficient in most cases. If you want to be safe, use Quit LabVIEW as well. That's my recommendation.
