AccessibleObject.UseStdAccessibleObjects Method

Definition

Namespace:

System.Windows.Forms

Assembly:

System.Windows.Forms.dll

Associates an object with an instance of an AccessibleObject.

Overloads

UseStdAccessibleObjects(IntPtr)	Associates an object with an instance of an AccessibleObject based on the handle of the object.
UseStdAccessibleObjects(IntPtr, Int32)	Associates an object with an instance of an AccessibleObject based on the handle and the object id of the object.

UseStdAccessibleObjects(IntPtr)

Source:

AccessibleObject.cs

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

protected:
 void UseStdAccessibleObjects(IntPtr handle);

protected void UseStdAccessibleObjects (IntPtr handle);

member this.UseStdAccessibleObjects : nativeint -> unit

Protected Sub UseStdAccessibleObjects (handle As IntPtr)

Parameters

handle

IntPtr

nativeint

An IntPtr that contains the handle of the object.

Remarks

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. This function is similar to CreateStdAccessibleProxy, except that CreateStdAccessibleProxy enables you to specify the class name as a parameter, whereas CreateStdAccessibleObject uses the class name associated with the hwnd.

Calling this version of the UseStdAccessible is the same as calling the two parameter version with an objid of CLIENT.

UseStdAccessibleObjects(IntPtr, Int32)

Source:

AccessibleObject.cs

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

protected:
 void UseStdAccessibleObjects(IntPtr handle, int objid);

protected void UseStdAccessibleObjects (IntPtr handle, int objid);

member this.UseStdAccessibleObjects : nativeint * int -> unit

Protected Sub UseStdAccessibleObjects (handle As IntPtr, objid As Integer)

Parameters

handle

IntPtr

nativeint

An IntPtr that contains the handle of the object.

objid

Int32

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.

Object	Value	Description
ALERT	0xFFFFFFF6	Refers to a message associated with a window or application.
CARET	0xFFFFFFF8	Refers to the text insertion bar (caret) in the window.
CLIENT	0xFFFFFFFC	Refers to the window's client area. In most cases, the operating system controls the frame elements, and the client object contains all elements that the application controls.

SIZEGRIP	0xFFFFFFF9	Refers to the window's size grip, an optional frame component located at the lower right corner of the window frame.
SOUND	0xFFFFFFF5	Refers to a sound object. Sound objects do not have screen locations or children, but do have name and state attributes. They are children of the application playing the sound.

TITLEBAR	0xFFFFFFFE	Refers to the window's title bar.
VSCROLL	0xFFFFFFFB	Refers to the window's vertical scroll bar.
