Help Project Components

If you have chosen to create a project with AppWizard using context-sensitive help, you will notice that quite a few new files have been added to your project directory. Most of these will reside in the hlp subdirectory of your project. You can view these files from Developer Studio by opening the Help Files folder in the FileView tab of the Workspace window. (The help project file (.hpj) is shown in the Source Files folder.)

Depending on your particular application, the help project will consist of one or more of the following sorts of files:

• .rtf files: These are specially formatted rich-text format (RTF) files that make up the body of your help text, including additional information like hyperlinks.
• .bmp files: Bitmap files may be added to your help project. These are added as illustrations in the help text to represent particular items in the user interface. The projects created by AppWizard will include a bitmap for each of the toolbar buttons on the standard toolbar.
• .cnt file: Each help project will contain a single file that holds the information used to present a table of contents for the help file.
• .hpj file: The help project file is used to control how all of the individual components of your help project are put together to build the .hlp file that is used by your application.
• MakeHelp.bat: To help with building your help project, AppWizard creates a batch file named MakeHelp.bat that will handle the task of building your help project. This batch file is called when your application project is built.
• .hm files: In addition, if you have built your project, you will notice one or more help map files. These files are used to map resource identifiers to the help context values that are used in working with the .hlp file. These are generated by the help map utility, makehm.exe, which is called from within MakeHelp.bat.

The next few sections discuss each of these file types in more detail.
