Providing On Item Help for Front Panel Controls

There are two ways to provide help for a control:

• Providing a help string in the control definition.

  The help string is displayed in the help viewer when the user invokes on-item help for the control. The help string cannot include formatting (such as headings) or links.

  To provide a help string, specify it in the control definition:

  	HELP_STRING   			 help_string
  

• Specifying a help topic in a registered help volume.

  A help topic is information authored using the full capabilities of the help system. Authoring a help topic requires you to use the desktop Help Developer's Kit.

  To provide a help topic, specify the help volume and topic ID in the control definition:

  	HELP_VOLUME				help_volume_name
   	HELP_TOPIC				topic_id
