AccessibleObject.UseStdAccessibleObjects Method (IntPtr, Int32)

This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

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

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)
[SecurityPermissionAttribute(SecurityAction.Demand, Flags = SecurityPermissionFlag.UnmanagedCode)]
protected void UseStdAccessibleObjects(
	IntPtr handle,
	int objid
)

Parameters

handle
Type: System.IntPtr

An IntPtr that contains the handle of the object.

objid
Type: System.Int32

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

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 IAccessible methods and properties as needed to match their custom object. This approach saves server developers the work of fully implementing all the IAccessible properties and methods.

Valid objid values.
