||Retrieves a process handle from a window handle.
||Retrieves the localized string that describes the object's role for the specified role value.
||Retrieves a localized string that describes an object's state for a single predefined state bit flag. Because state values are a combination of one or more bit flags, clients call this function more than once to retrieve all state strings.

||Removes an event hook function created by a previous call to SetWinEventHook.
||Retrieves the window handle that corresponds to a particular instance of an IAccessible interface.
|WinEventProc Callback Function
||An application-defined callback (or hook) function that the system calls in response to events generated by an accessible object. The hook function processes the event notifications as required. Clients install the hook function and request specific types of event notifications by calling SetWinEventHook.
The WINEVENTPROC type defines a pointer to this callback function. WinEventProc is a placeholder for the application-defined function name.
