C++ Exceptions Will Not Cross COM Boundaries

C++ Exceptions Will Not Cross COM Boundaries

When writing a COM object using C++, care should be taken to ensure that all C++ exceptions generated by the code are handled within the call itself. If any C++ exception is not handled, the call will fail.

For example:

 CMyComObject::foo(){ HRESULT hr;... throw hr;}
