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.

Implements

ComposeHwndIdentityString(_RemotableHandle, UInt32, UInt32, IntPtr, UInt32)
