If Help file is indicated in HelpFile, it is called automatically when the user clicks Help button (or presses the F1 key) in the error message dialog box. If the VBScript Err Object HelpContext Property has a valid context ID for the indicated file, that topic is displayed automatically. If no HelpFile is indicated, the VBScript Help file is displayed.
