Retrieves the string message for HRESULT stored in the _com_error object.

const TCHAR * ErrorMessage( ) const throw( );

Returns the string message for the HRESULT recorded within the _com_error object. If the HRESULT is a mapped 16-bit wCode, then a generic message "IDispatch error #<wCode>" is returned. If no message is found, then a generic message "Unknown error #<hresult>" is returned. The returned string is either a Unicode or multibyte string, depending on the state of the _UNICODE macro.

Retrieves the appropriate system message text for HRESULT recorded within the _com_error object. The system message text is obtained by calling the Win32 FormatMessage function. The string returned is allocated by the FormatMessage API, and it is released when the _com_error object is destroyed.
