Sometimes you can select VI properties that make it difficult to edit a VI. For example, you might select the Run When Opened option and disable the menu bar and toolbar. If you set the VI to close and exit LabVIEW after it runs, you cannot stop the VI and edit it without it closing and exiting LabVIEW. This VI would be very difficult to edit. To exit LabVIEW, you can use the Quit LabVIEW function located on the Functions>>All Functions>>Application Control palette. This function aborts all running VIs and ends the current session of LabVIEW. The function has one input. If it is wired, the end of the LabVIEW session occurs only if that input is True. If the input is not wired, the end of the session occurs when the node executes. Before you change VI properties, save a backup of the VI to a new location by selecting File>>Save with Options to avoid situations like the previous examples. Select the Development Distribution option to save the VI to a new location along with its entire hierarchy. You also can include the vi.lib files in the save. After you save the backup VI, change the VI properties of the original VI. If you encounter a problem, you can return to the backup VI. If you select the Remove diagrams option, you remove the source code of the VI. Select this option only if you never need to edit the VI again. Before you save a VI without the block diagrams, save a backup of the VI with the block diagrams. If you already saved a development VI with properties that make the VI difficult to edit, refer to the Edit Me VI exercise for more information about editing the VI.
