Remarks

The CreateAccessibilityInstance method creates an object to provide information that accessibility applications use to adjust an application's user interface (UI) for users who have impairments.

If you do not explicitly call the CreateAccessibilityInstance method, it will be called when the AccessibilityObject property is referenced.

ملاحظة

To get or set the AccessibilityObject property, you must add a reference to the Accessibility assembly that is installed with the .NET Framework.

Notes to Inheritors

When you override CreateAccessibilityInstance in a derived class, do not call the CreateAccessibilityInstance method of the base class.
