AccessibleObject.UseStdAccessibleObjects Method

  • Reference

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)

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.

Applies to

Parameters

handle
IntPtr

nativeint

An IntPtr that contains the handle of the object.

objid
