UiaIAccessibleFromProvider function

Retrieves an IAccessible implementation that provides Microsoft Active Accessibility data on behalf of a Microsoft UI Automation provider.

Syntax

C++


HRESULT WINAPI UiaIAccessibleFromProvider(
  _In_  IRawElementProviderSimple *pProvider,
  _In_  DWORD                     dwFlags,
  _Out_ IAccessible               **ppAccessible,
  _Out_ VARIANT                   *pvarChild
);

Parameters

pProvider [in]

Type: IRawElementProviderSimple*

A pointer to the UI Automation object.

dwFlags [in]

Type: DWORD

One of the following values:

UIA_IAFP_DEFAULT
UIA_IAFP_UNWRAP_BRIDGE

ppAccessible [out]

Type: IAccessible**

Receives the pointer to the IAccessible implementation for the provider.

pvarChild [out]

Type: VARIANT*

Receives the child identifier of the accessible element in the lVal member.

Return value

Type: HRESULT

If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Remarks

In most cases, this function retrieves a wrapper object, provided by Windows, that implements IAccessible on behalf of the IRawElementProviderSimple object. If the provided IRawElementProviderSimple pointer is itself a wrapper object, this function retrieves the wrapped IAccessible pointer and returns that instead, to prevent the creation of multiple layers of wrappers.
