225 Chapter 11: Context-sensitive Help About context-sensitive Help A context-sensitive Help (CSH) topic provides information about the user interface of an application relative to the task a user performs. For example, CSH topics provide details about fields and controls in dialog boxes, descriptions of windows or screen objects, and explanations of messages. The user accesses a CSH topic by pressing F1, clicking a Help button, selecting from a menu, or clicking a question-mark icon. The process of creating and implementing context-sensitive Help typically involves the content author and the application developer. To specify context-sensitive topics, the author creates map IDs and map files. When a user accesses context-sensitive Help, a map number and Help file name are sent to the Help engine. The engine matches the map number to a topic ID and an HTM filename so that the correct topic appears. The final step in the process is to test the context-sensitive Help. RoboHelp HTML provides several tools you can use in addition to testing context-sensitive Help in the application. Window-level topic Describes windows, dialog boxes, and messages in an application. Each window-level topic is in HTM format and stored in a file with the extension .htm. It can contain text formatting, links, images, and other features. These topics are more detailed than field-level topics because they describe the user interface components. Users access these topics by pressing F1, clicking Help buttons, and selecting from menus. If a custom window is not included with the application Help, context-sensitive topics appear in the HTML Help viewer. Field-level (What's This?) topic (WinHelp and Microsoft HTML Help projects) Briefly describes a field. A user accesses the topic by clicking a question-mark icon, and then clicking a field in a dialog box. In RoboHelp, field-level topics are called What's This? topics. Note: WebHelp, WebHelp Pro, FlashHelp, FlashHelp Pro, and AIR Help do not support What's This Help. WebHelp window support is available only with the context-sensitive Help API (Application Programming Interface). Airplane Help Offline Help unsupported by an Internet connection. To use RH_ShowHelp, associate the offline Help system with the function RH_AssociateOfflineHelp. This step tells the function how to operate if no Internet connection is available. Individual calls to RH_ShowHelp must specify offline Help. Both RH_ShowHelp and RH_AssociateOfflineHelp are in the support files. Use airplane Help to provide back-up Help when an Internet connection fails. Note: RH_ShowHelp is a programming function that a developer uses to display a help topic using rules found in RoboHelp's CSH API. Last updated 12/14/2011

Chapter 11: Context-sensitive Help
About context-sensitive Help
A context-sensitive Help (CSH) topic provides information about the user interface of an application relative to the
task a user performs. For example, CSH topics provide details about fields and controls in dialog boxes, descriptions
of windows or screen objects, and explanations of messages. The user accesses a CSH topic by pressing F1, clicking a
Help button, selecting from a menu, or clicking a question-mark icon.
The process of creating and implementing context-sensitive Help typically involves the content author and the
application developer. To specify context-sensitive topics, the author creates
map IDs
and
map files
. When a user
accesses context-sensitive Help, a
map number
and
Help file
name are sent to the
Help engine
. The engine matches the
map number to a topic ID and an HTM filename so that the correct topic appears.
The final step in the process is to test the context-sensitive Help. RoboHelp HTML provides several tools you can use
in addition to testing context-sensitive Help in the application.
Window-level topic
Describes windows, dialog boxes, and messages in an application. Each window-level topic is in
HTM format and stored in a file with the extension .htm. It can contain text formatting, links, images, and other
features. These topics are more detailed than field-level topics because they describe the user interface components.
Users access these topics by pressing F1, clicking Help buttons, and selecting from menus.
If a custom window is not included with the application Help, context-sensitive topics appear in the HTML Help
viewer.
Field-level (What's This?) topic
(WinHelp and Microsoft HTML Help projects) Briefly describes a field. A user
accesses the topic by clicking a question-mark icon, and then clicking a field in a dialog box. In RoboHelp, field-level
topics are called
What’s This?
topics.
Note:
WebHelp, WebHelp Pro, FlashHelp, FlashHelp Pro, and AIR Help do not support What’s This Help. WebHelp
window support is available only with the context-sensitive Help API (Application Programming Interface).
Airplane Help
Offline Help unsupported by an Internet connection. To use
RH_ShowHelp
, associate the offline Help
system with the function
RH_AssociateOfflineHelp
. This step tells the function how to operate if no Internet
connection is available. Individual calls to
RH_ShowHelp
must specify offline Help. Both
RH_ShowHelp
and
RH_AssociateOfflineHelp
are in the support files. Use airplane Help to provide back-up Help when an Internet
connection fails.
Note:
RH_ShowHelp is a programming function that a developer uses to display a help topic using rules found in
RoboHelp's CSH API.
