1<\/font> Even though _bstr_t<\/code>
\n    provides conversion operators to non-const<\/span><\/code>
\n    pointers, modifying the underlying buffer may cause a GPF if you overrun the
\n    buffer, or a leak when the BSTR<\/code> memory is freed.
\n    2<\/font> A _bstr_t<\/code> holds a BSTR<\/code>
\n    internally in a wchar_t*<\/code> variable, so you can use the 
\n    const<\/span> wchar_t*<\/code> converter to retrieve
\n    the BSTR<\/code>. This is an implementation detail, so use this with
\n    caution, as it may change in the future.
\n    3<\/font> This will throw an exception if the data cannot
\n    be converted to a BSTR<\/code>.
\n    4<\/font> Use ChangeType()<\/code> then access the
\n    bstrVal<\/code> member of the VARIANT<\/code>. In MFC, this will
\n    throw an exception if the data cannot be converted.
\n    5<\/font> There is no BSTR<\/code> conversion
\n    function, however the AllocSysString()<\/code> method returns a new
\n    BSTR<\/code>.
\n    6<\/font> You can temporarily get a non-const TCHAR<\/code>
