You may want to use different help formats in your application:

• HTML help;
• NetHelp;
• MS Help 2.0;
• WinHelp;
• RoboHelp WebHelp;
• and so on.

C1DynamicHelp provides means for displaying these or any other help formats.

HTML Help and NetHelp formats can be displayed by the C1DynamicHelp control without any additional programming. There are two built-in help providers in C1DynamicHelp, ChmProvider and NetHelpProvider, which are used automatically when the HelpSource property points to a .chm or an .htm/html file, correspondingly.

Any other types of help files can be used, but this requires some additional programming. In this case you will have to create your own help provider class that implements the IHelpProvider interface. This interface provides all necessary information about a help format to the C1DynamicHelp control. So any help provider can read data from a help source and provides methods to get help topics, to get context IDs, to open help in an external window, to get a topic URL that can be displayed by the C1DynamicHelp control, and so on. After creating your own help provider, all you need is to set it to the Provider property.

For more details see:

• the IHelpProvider interface, which must be implemented by every help provider;
• the Provider property;
• the NetHelpProvider sample, which is the full code actually used in the C1DynamicHelp control.
