1198 HEIDENHAIN Technical Manual iTNC 530 HSCI
HEIDENHAIN has specified here the name of the CHM file and the file name
merged.hhc of the table of contents contained therein. When the welcome
page of the help system (main.chm) is called, all existing help files linked with
merge commands are included. Each table of contents is only displayed if it
exists in a file named merged.hhc. This is why it is essential that you include
the directory structure of your help as merged.hhc when your generate your
OEMx.CHM files.
The first level of this table of contents should have exactly one entry: the title
of the help file. This title then appears as a "book" in the entire table of
contents, and can be opened by the user in order to show the subordinate
headings.
Along with the actual HTML pages, the following files must be included when
generating the OEMx.CHM files:
 *.hhc file
In this file you describe the structure and format of your help system. If you
call your help file via main.chm, then this file must be named merged.hhc. If
your help file is to be called directly, without main.chm, then the directory
tree in the *.hhc file that you indicated as content file when you created the
CHM file is used.
 *.hhk file
In this file you list all entries that are to be shown in the index later, and
create the links to the corresponding HTML pages. At least one entry is
necessary here in order for your help file to be displayed.
 *.hhp file
This file is the project file that is necessary for generating an OEMx.CHM
file.
 *.h file (only necessary for context-sensitive help)
In this file you use the #define command to establish connections between
error numbers, from the respectively valid ranges of error numbers, and any
variables.
Example:
#define IDH_OEM1_CHAP110000000
#define IDH_OEM1_Page1_110000100
 *.txt file (only necessary for context-sensitive help)
In this file you establish the connection between the variables and the
corresponding HTML pages, which are then called.
Example:
IDH_OEM1_CHAP1=chapter1.html
IDH_OEM1_Page1_1=page11.html
