Note that this requires ATs to make an extra call (IAccessibleText::nCharacters) to determine the length. Extra calls do matter across process boundaries. We do this anyway, but it's worth adding to the discussion. > I am tempted to return E_INVALIDARG if get boundaryType == > IA2_TEXT_BOUNDARY_ALL in textAfterOffset and textBeforeOffset. Would > that break anybody? Hmm. That makes it look like the caller is wrong to try to use it when it is in the spec. I'd prefer E_NOTIMPL, but I realise that's only supposed to be used when the entire method isn't implemented. Are there any other options that indicate that this particular request isn't implemented?
