throwing exception from COM and catching it in ASP
Never ever throw an exception across COM boundaries. COM component
should return failed HRESULT, and optionally set up IErrorInfo object.
#import-generated smart wrappers convert those failed HRESULTs to C++
exceptions on the client side.
See AtlReportError, CComCoClass::Error
