System.Windows.Forms.AccessibleObject.UseStdAccessibleObjects Method

Associates an object with an instance of an System.Windows.Forms.AccessibleObject based on the handle and the object id of the object.

Syntax

protected void UseStdAccessibleObjects (IntPtr handle, int objid)

Parameters

handle
An IntPtr that contains the handle of the object.
objid
An Int that defines the type of object that the handle parameter refers to.

Remarks

Creates an accessible object with the methods and properties for the specified type of system-provided user interface element.

Server applications can call this function when they contain a custom UI object that is similar to a system-provided object. Server applications call CreateStdAccessibleObject and override the Accessibility.IAccessible methods and properties as needed to match their custom object. This approach saves server developers the work of fully implementing all the Accessibility.IAccessible properties and methods.

Valid objid values.
