Assign Information Types
Information types allow you to customize your help topics to specify that designated topics will reach a particular audience. To achieve this, you create categories and information types, select attributes for them, and assign help topics to them.
Information types have an Exclusive, Inclusive or Hidden attribute. By assigning one or more information types with an Inclusive or Exclusive attribute, you can determine which topics a group of users will see in the table of contents. By assigning a Hidden attribute, you can invoke the HTMLHelp API to connect topics to events in a program.
