Help Property

The Help property provides information that tells the user about the function of an object.

The Help property is retrieved by calling IAccessible::get_accHelp.

This property contains balloon-style information (as found in ToolTips) that is used either to describe what the object does or how to use it. For example, the Help property for a toolbar button that shows a printer might provide the following text: "Prints the current document."

The text for the Help property does not have to be unique within the user interface.

When to Support the Help Property

Servers do not support the Help property if other properties provide sufficient information about the object's purpose and the actions the object performs. Accessible objects that expose system-provided controls do not support the Help property.
