To provide context-sensitive help for a part, you simply specify the help information in the settings for the part.
To do this for a part in your application, open its settings. Specify values for the part's help properties as follows:
In OS/2, the current directory and the directories specified in the HELP environment variable are used to locate the help file.
In Windows, use the PATH environment variable.
In UNIX systems, use the DTHELPUSERSEARCHPATH environment variable.
For OS/2 help files, the Topic ID must match the number specified in the panel's heading tag res= attribute (or the string specified in the id= or name= attribute).
For Windows help files, the Topic ID must match the numeric value in the project file's [[MAP] section that is associated with the help panel ID.
For UNIX, the Topic ID must match the value specified for the id attribute of a heading.
For Windows and UNIX systems, this setting has no effect. You specify the title of the main help window in the help project file.
Now, test the help file by, for example, pressing the F1 key while the main help window's focus is on a part that has context-sensitive help.
