Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
To control the instance returned from this method, override the CreateAccessibilityInstance method.
If no AccessibleObject is currently assigned to the control, a new instance of one is created.
To get or set the AccessibilityObject property, you must add a reference to the Accessibility assembly installed with the .NET Framework.
For more information about accessible objects, see the "Active Accessibility" section of the MSDN Library at http://msdn.microsoft.com/library.
