If you link a VI to an HTML file or to a compiled help file, a link to that file appears in the Context Help window when you move the cursor over the VI icon.
Complete the following steps to link a VI to an HTML file or to a compiled help file.
Select File»VI Properties to display the VI Properties dialog box.
Select Documentation from the Category pull-down menu.
Click the Browse button, navigate to the .chm, .hlp, .htm, or .html file you want to link to, and click the Open button. The file path appears in the Help Path text box.
If Help Path contains a path to an .htm or .html file, LabVIEW ignores the Help Tag text box. If Help Path contains a path to a compiled help file (.chm or .hlp), use the Help Tag text box to link the VI to a specific topic in that help file:
For .chm files, you can enter a .htm or .html filename or an index keyword in the Help Tag text box. The .htm or .html filename must match the name of an individual, uncompiled HTML file in your HTML Help project. The index keyword must match a keyword in the index of your HTML Help project.
If you want to link to a .chm file on Windows and link to the uncompiled HTML files on Macintosh and UNIX, enter the HTML filename in the Help Tag text box. On Windows, LabVIEW links to the HTML file inside the .chm file. On Macintosh and UNIX, LabVIEW ignores the .chm filename and links to the HTML file, which must be in the help\html directory.
For .hlp files, you can enter an index keyword in the Help Tag text box. The index keyword must match a keyword in the index of your WinHelp, QuickHelp, or HyperHelp project.
Click the OK button to save the changes. When you move the cursor over the VI icon, a blue Click here for more help. link appears in the Context Help window, and the More Help button is enabled.
Click the blue link or the More Help button in the Context Help window to test the link from the VI to the HTML or compiled help file. You also can place the VI on a block diagram, right-click the VI icon, and select Help from the shortcut menu.
If you link from VIs to HTML files or compiled help files and you use the VIs to build a stand-alone application, you must include the files as source files when you build the application.
You also can use the Help functions located on the Functions»Application Control»Help palette or the Document Path and Document Tag properties to link from VIs to HTML files or compiled help files programmatically.
