IAccPropServices::SetHwndPropStr

This method wraps SetPropValue, providing a more convenient entry point for callers who are annotating Hwnd-based objects.

HRESULT SetHwndPropStr (
  HWND hwnd,
  DWORD idObject,
  DWORD idChild,
  MSAAPROPID idProp,
  LPCWSTR str
);

Parameters

hwnd, idObject, idChild
[in] Identifies the accessible element that is to be annotated. This replaces the identity string.
idProp
[in] Specifies which property of that element is to be annotated.
str
[in] Specifies a new value for that property.

Return Values

If successful, returns S_OK.

Returns E_INVALIDARG if any of the properties in the paProps array are not supported properties, if the identity string is not valid, or if annoScope is not one of ANNO_THIS or ANNO_CONTAINER.

May return other error codes under exceptional error conditions such as low memory.

Remarks

By using this method, the caller does not have to obtain an identity string; it can specify the hwnd, idObject, and idChild parameters directly.
