Opening Context-Sensitive Help with the WebWorks Help API
WebWorks Help provides an API that you can use to call context-sensitive topics in WebWorks Help. Using the API instead of simple URLs gives you increased flexibility and enhanced control. For example, the following list highlights some of the benefits of using the API:
The API automatically determines the default browser and opens it to display the correct help topic.
The API reduces the amount of code developers must write to integrate context-sensitive help. Without the API, developers must code their own COM interface to communicate with the browser on the Windows platform. This code is provided as part of the WebWorks Help API.
Using the API can significantly reduce the time required to load an individual topic if the help system is already open in the browser. If your application calls a topic using a URL instead of the API, the entire frameset, including the WebWorks Help applet, is loaded each time the user opens help. If the application calls a topic using the API, and the correct help is already loaded in the browser, neither the frameset nor the applet is reloaded. Instead, the currently open topic pane displays the correct help topic, which delivers a significant performance improvement for WebWorks Help users.
You can use the C/C++ API, which is available as a .dll or a COM object. This API supports WebWorks Help 4.0 and 5.0. WebWorks HelpĀ 5.0, does not include the Java navigation. Therefore, do not use the Java navigation options with WebWorks HelpĀ 5.0.

You can use the JavaScript API. For more information, see wiki.webworks.com/DevCenter/Projects/WebWorksHelp/JavascriptAPI.
