Hello Ren=E9, Thank you for contacting National Instruments.
As Weibe has answered, there is no way to disable the front panel scroll bars after the VI has finished running. To prevent users from altering the VI, you can set the front panel to close upon completion. You can do this by including a =93Quit LabVIEW=94 function from Functions >> Application Control. You should wire the stop button from your while loop to the =93Quit LabVIEW=94 function to have the front panel close at the end of execution. If you are calling your VI from another VI, you can set the front panel to close from VI Properties. Select File >> VI Properties then select Window Appearance from the pull down category menu. Press the customize button and select the Show Front Panel when Called and Close Afterwards if Originally Closed boxes. I hope this helps, Sean C. Applications Engineer National Instruments
