Implementing a Server-Side UI Automation Provider • • 8 minutes to read In this article This topic describes how to implement a server-side Microsoft UI Automation provider for a custom control written in C++. It contains the following sections: • • • • • • • • • For code examples that show how to implement server-side providers, see. Provider Interfaces The following Component Object Model (COM) interfaces provide functionality for custom controls. To provide basic functionality, every UI Automation provider must implement at least the interface. The and interfaces are optional, but should be implemented for elements in a complex control to provide additional functionality. Interface Description Provides basic functionality for a control hosted in a window, including support for control patterns and properties. Adds functionality for an element in a complex control, including navigating in the fragment, setting focus, and returning the bounding rectangle of the element. Adds functionality for the root element in a complex control, including locating a child element at specified coordinates and setting the focus state for the entire control. Note In the UI Automation API for managed code, these interfaces form an inheritance hierarchy. This is not the case in C++, where the interfaces are completely separate. The following interfaces provide added functionality but implementation is optional. Interface Description Enables the provider to track requests for events. Enables repositioning of window-based elements in the UI Automation tree of a fragment. Required Functionality for UI Automation Providers To communicate with UI Automation, your control must implement the main areas of functionality described in the following table.

Property Values UI Automation providers for custom controls must support certain properties that can be used by UI Automation and by client applications. For elements that are hosted in windows, UI Automation can retrieve some properties from the default window provider, but must obtain others from the custom provider. Typically, providers for window-based controls do not need to provide the following properties that are identified by PROPERTYID: • • • • • • • • • • The RuntimeId property of a simple element or fragment root hosted in a window is obtained from the window. However, fragment elements below the root, such as list items in a list box, must provide their own identifiers. For more information, see. The IsKeyboardFocusable property should be returned for providers hosted in a Windows Forms control. In this case, the default window provider may be unable to retrieve the correct value. The Name property is usually supplied by the host provider. Events from Providers UI Automation providers should raise events to notify client applications of changes in the state of the UI. The following functions are used to raise events. Function Description Raises various events, including events triggered by control patterns. Raises an event when a UI Automation property has changed.
