Option Description
General Use this section to set general VI Revision History options.
  • 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 does not contain a checkmark by default.

    You also can use the History:Revision Number property to display the revision number programmatically.
Add Comments to VI Revision History Use this section to configure when to add comments to the VI Revision History.
  • 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 does not contain a checkmark 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 this 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.

  • 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 does not contain a checkmark 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 does not contain a checkmark by default.

    You also can use the History:Record Application Comments property to add comments to the VI revision history programmatically.
User Name to Record in VI Revision History Use this section to choose which user name to record in the VI Revision History.
  • LabVIEW registration name—

    (Windows and macOS) 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.
