From the front panel or block diagram window of a VI, select File»VI Properties and select Documentation from the Category pull-down menu to display this page.

Use this page to create VI descriptions and to link from VIs to HTML files or to compiled help files.

This page includes the following components:

Option Description
VI description

Contains the text that appears in the Context Help window if you move the cursor over the VI icon.

Use <B> and </B> tags around any text in the description you want to format as bold. You also can use the VI Description property to edit the VI description programmatically.

Note If you do not provide a VI description for a dynamic child member VI in a LabVIEW class, LabVIEW displays the description for the nearest ancestor class dynamic member VI of the same name, if available.
Help Used

Indicates whether to link a VI to web-based or local custom documentation from the Context Help window. If you specify to use web-based documentation, enter the URL of the help file in the Help URL text box.

Contains the URL for the web-based help file you want to link to from the Detailed help link and the Detailed help button in the Context Help window.
Help path

You also can use the Help:Document Path property to set the help path programmatically.

Note If you do not provide a Detailed help link for a dynamic child member VI in a LabVIEW class or interface, LabVIEW displays the Detailed help link for the nearest ancestor class dynamic member VI of the same name, if available.
