Select Tools»Options to display the Options dialog box and select Environment from the Category list to display this page.

Use this page to set miscellaneous options for the LabVIEW environment.

This page includes the following components:

• End text entry with Enter key—Allows you to press the <Enter> key on the keyboard to end text entry. This checkbox is unchecked by default. If you place a checkmark in this checkbox, the <Enter> key on the keyboard works like the <Enter> key on the numeric keypad, ending text entry. Press the <Ctrl-Enter> keys on the keyboard to embed new lines in a text box. (Mac OS) Press the <Option-Return> keys. (Linux) Press the <Alt-Return> keys.
• Show tip strips—Displays tip strips. This checkbox is checked by default.
• Show created constant labels—Shows labels with the name of the terminal from which the constant was created. This checkbox is unchecked by default.
• Open VIs in run mode—Opens VIs in run mode, in which the VI is running or reserved to run, instead of edit mode, in which you can make changes to a VI. This checkbox is unchecked by default.
• Use native file dialogs—(Windows and Mac OS) Uses the native file dialog boxes in LabVIEW so they act similar to other applications on the computer. This checkbox is checked by default. If you remove the checkmark from this checkbox, LabVIEW uses its own platform-independent file dialog boxes with some convenient features, such as providing a list of recent paths and reducing the steps necessary to save VIs in LLBs.
• Allow drop-through clicks—(Windows and Mac OS) Allows you to click the mouse once to activate and select an object in an inactive window. This checkbox is checked by default.
• Automatically close VISA sessions—Automatically closes VISA sessions left open by the application when the top-level VI becomes idle. This checkbox is unchecked by default.
• Skip Getting Started window on launch—Opens a new, blank VI instead of the Getting Started window when you launch LabVIEW. This checkbox is unchecked by default.
• Treat read-only VIs as locked—Primarily used for source control, this option restricts editing on read-only VIs. This checkbox is checked by default. If you do not place a checkmark in this checkbox, you can edit VIs even though they are read-only, but you cannot save them. If you place a checkmark in this checkbox, a VI that is read-only opens as locked, and you cannot edit it.
  • Do not save automatic changes—Does not prompt you to save any changes automatically implemented by LabVIEW. You do not need to save these changes because LabVIEW implements the changes each time the VI is loaded. Changes automatically implemented by LabVIEW include recompiling, converting from an older version, and updating type definitions or fonts. This checkbox is unchecked by default.
• Disable menu animation—Disables menu animation features, such as fading or scrolling menus, on Windows 2000. You must have this feature enabled on the computer to disable or enable this feature in LabVIEW. Refer to the Windows 2000 documentation for information about enabling window animation on the computer. This checkbox is unchecked by default.
• Lock automatic tool selection—Keeps automatic tool selection enabled when you press the <Tab> or <Shift-Tab> keys. This checkbox is checked by default. Remove the checkmark from this checkbox to configure LabVIEW to disable automatic tool selection when you press the <Tab> key and to toggle automatic tool selection when you press the <Shift-Tab> keys.
• Enable automatic saving for recovery—Automatically saves open files at the specified intervals. In the event of an irregular shutdown or system failure, the Select Files to Recover window displays recoverable files the next time you launch LabVIEW.
  • Save before a VI runs—Backs up open files before you run a VI.
  • Save before a VI runs and periodically—Backs up open files before you run a VI and at the intervals specified in the minutes field.
    • minutes—Specifies how often LabVIEW backs up open files. You must select Save before a VI runs and periodically to enable this field.
• Enable Just-In-Time Advice—Displays the Just-In-Time Advice window when you perform certain actions in LabVIEW. This dialog box alerts you to changes between a previous version of LabVIEW and the current version of LabVIEW. Place a checkmark in this checkbox to enable the Just-In-Time Advice window.
• Maximum undo steps per VI—Sets the maximum number of steps that you can undo. If Use default is checked, you cannot edit this field. The default is 8 steps. The maximum number you can enter is 99. The minimum number you can enter is 1.
  • Use default—Sets Maximum undo steps per VI to its default value of 8. This checkbox is checked by default. To edit Maximum undo steps per VI, remove the checkmark from the checkbox.
• Clear Password Cache—Clears the LabVIEW password cache. If you have password-protected VIs, LabVIEW caches the password when you access the block diagrams so that you do not have to re-enter the password in the same session. If you clear the password cache, the next time you access a password-protected block diagram, you must re-enter the password. When you clear the password cache, LabVIEW closes any open block diagrams of password-protected VIs.
