Definition

Namespace:

Accessibility

Assembly:

Accessibility.dll

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

public:
 void ComposeHwndIdentityString(Accessibility::_RemotableHandle % hwnd, System::UInt32 idObject, System::UInt32 idChild, IntPtr ppIDString, [Runtime::InteropServices::Out] System::UInt32 % pdwIDStringLen);

public void ComposeHwndIdentityString (ref Accessibility._RemotableHandle hwnd, uint idObject, uint idChild, IntPtr ppIDString, out uint pdwIDStringLen);

abstract member ComposeHwndIdentityString : _RemotableHandle * uint32 * uint32 * nativeint * uint32 -> unit

Public 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.
