CAccPropServicesClass.ComposeHwndIdentityString Method

Definition

The CAccPropServicesClass and all of its exposed members are part of a managed wrapper for the Component Object Model (COM) IAccPropServices interface.

public:
 virtual void ComposeHwndIdentityString(Accessibility::_RemotableHandle % hwnd, System::UInt32 idObject, System::UInt32 idChild, IntPtr ppIDString, [Runtime::InteropServices::Out] System::UInt32 % pdwIDStringLen) = Accessibility::IAccPropServices::ComposeHwndIdentityString;
public virtual void ComposeHwndIdentityString (ref Accessibility._RemotableHandle hwnd, uint idObject, uint idChild, IntPtr ppIDString, out uint pdwIDStringLen);
abstract member ComposeHwndIdentityString : _RemotableHandle * uint32 * uint32 * nativeint * uint32 -> unit
override this.ComposeHwndIdentityString : _RemotableHandle * uint32 * uint32 * nativeint * uint32 -> unit
Public Overridable Sub ComposeHwndIdentityString (ByRef hwnd As _RemotableHandle, idObject As UInteger, idChild As UInteger, ppIDString As IntPtr, ByRef pdwIDStringLen As UInteger)

Parameters

hwnd
_RemotableHandle

Specifies the HWND of the accessible element that the caller wants to identify.

idObject
UInt32

Specifies the object ID of the accessible element.

idChild
UInt32

Specifies the child ID of the accessible element.

ppIDString
IntPtr

nativeint

Pointer to a buffer that receives the identity string. The callee allocates this buffer using CoTaskMemAlloc. When finished, the caller must free the buffer by calling CoTaskMemFree.

pdwIDStringLen
UInt32

Pointer to a buffer that receives the length of the identity string.
