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

Use this page to set revision history options for all new VIs. Use the VI Properties dialog box to set options for the current VI.

This page includes the following components:

• Add an entry every time the VI is saved—Automatically generates a comment in the History window if you change the VI and save it. If you do not enter a comment in the Comment box of the History window, LabVIEW adds only a header to the history if the History»Show Empty Entries option is selected in the History window. This checkbox is unchecked by default. The header contains the revision number, if Show revision number in titlebar has no checkmark, the date, the time, and the name of the VI. You also can use the History: Always Add Comments At Save property to add comments to the VI revision history programmatically.
• Prompt for a comment when the VI is closed—Prompts you to add a comment to the History window if you made any changes to the VI since you opened it, even if you already saved those changes. LabVIEW does not prompt you to add a comment to the History window if you did not make any changes. LabVIEW does not prompt you to type a comment if you changed only the history. This checkbox is unchecked by default. You also can use the History: Prompt for Comments At Close property to add comments to the VI revision history programmatically.
• Prompt for a comment when the VI is saved—Prompts you to add a comment to the History window if you made any changes to the VI since you last saved it. This checkbox is unchecked by default. This option is useful if you prefer to comment on the changes when you finish making them instead of as you are editing. If you do not place a checkmark in this checkbox, you cannot change the history after you select File»Save until the save is finished. LabVIEW does not prompt you to add a comment to the History window if you did not make any changes or if you changed only the history. You also can use the History: Prompt for Comments At Save property to add comments to the VI revision history programmatically.
• Record comments generated by LabVIEW—Automatically generates a comment in the History window when you save the VI if LabVIEW made any automatic changes to the VI, such as recompiling the VI for a new version of LabVIEW. This checkbox is unchecked by default. You also can use the History:Record Application Comments property to add comments to the VI revision history programmatically.
• Show revision number in titlebar—Adds the revision number to the header of the History window. The revision number starts at zero and increases incrementally every time you save the VI. However, it does not increase if you changed only the history. This checkbox is unchecked by default. You also can use the History:Revision Number property to display the revision number programmatically.
• Name to use for VI Revision History—Selects the user name to use in the History window. The default is Operating System user name. You can choose to use:
  • LabVIEW registration name—(Windows and Mac OS) Uses the name of the registered user of the application.
  • Operating System user name—Assuming that a user name has been defined for the operating system, uses the system login name of the current user. If a user name has not been defined, an unregistered user dialog box appears.
  • Prompt user to select at LabVIEW startup—Prompts you for a user name when LabVIEW starts. Change the user name at any time by selecting Tools»User Name. The prompt displays a menu of all user names previously entered into LabVIEW with this option. (Windows and Mac OS) You can switch to the user name from the operating system or the application registration name. (Linux) You can switch to the user name from the operating system. In both instances, you can select the user name by using the pull-down menu so you do not have to type the user name. You also can type a name, which then appears in the list.
