Error Values

[C++] This method returns S_OK (0x00000000) to indicate success and either standard or custom COM HRESULT error values to indicate failure. For more information about standard COM errors, see Standard COM Errors.

[Visual Basic] This method sets the Number property of the global Err object to S_OK (&H00000000) or S_FALSE (&H00000001) to indicate success and to either standard or custom COM error values to indicate failure. If this method returns a property or object it will return Nothing on failure. The method may succeed and yet return Nothing due to a subtle syntax error or a request for a property or object that does not exist. Test the return value for Nothing before relying on it. For more information about standard COM errors, see Standard COM Errors.
