Creates a new accessibility object for the CheckBox control.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
If you do not explicitly call the method, it will be called when the AccessibilityObject property is referenced.
To get or set the AccessibilityObject property, you must add a reference to the Accessibility assembly installed with the .NET Framework.
When overriding in a derived class, you should not call the base class's method.
