Returns or sets a String expression containing the fully qualified path to a Help file. Read/write.
Public Property HelpFile() As String
If a Help file is specified by the HelpFile property, it is automatically called when the user presses the Help key (or the F1 key) in the error message dialog box. If the HelpContext property contains a valid context ID for the specified file, that topic is automatically displayed. If no HelpFile is specified, the Visual Basic Help file is displayed.
Note You should write routines in your application to handle typical errors. When programming with an object, you can use the object's Help file to improve the quality of your error handling, or to display a meaningful message to your user if the error isn't recoverable.
This example uses the HelpFile property of the Err object to start the Help system. By default, the HelpFile property contains the name of the Visual Basic Help file.
