Can not get the number of Shapes in Protected Mode

P

Philip Chan

After protecting the document, I can't get the number of Shapes of the
document.
The following code doesn't work:

CComPtr<Word::Shapes> pShapes;
hr = doc->get_Shapes(&pShapes);


and the returned hr is E_FAIL.

Can anyone tell the difference of behavior between normal mode and protected
mode?
