Creates a new accessibility object for the 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, do not call the base class's method.
The following code example demonstrates the creation of an accessibility-aware chart control, using the AccessibleObject and Control::ControlAccessibleObject classes to expose accessible information. The control plots two curves along with a legend. The ChartControlAccessibleObject class, which derives from ControlAccessibleObject, is used in the method to provide custom accessible information for the chart control. Since the chart legend is not an actual Control -based control, but instead is drawn by the chart control, it does not any built-in accessible information. Because of this, the ChartControlAccessibleObject class overrides the GetChild method to return the CurveLegendAccessibleObject that represents accessible information for each part of the legend. When an accessible-aware application uses this control, the control can provide the necessary accessible information.
This code excerpt demonstrates overriding the method. See the AccessibleObject class overview for the complete code example.
