Comentarios

Las aplicaciones cliente usan este identificador Automatización de la interfaz de usuario. Automatización de la interfaz de usuario proveedores deben usar el campo equivalente en SelectionItemPatternIdentifiers.

El identificador de patrón se pasa a métodos como GetCurrentPattern para recuperar el patrón de control de interés del especificado AutomationElement.
