Method AutomationObject():onError()

Default error handler for errors generated in the automation sub-system.

:onError( <oError> ) --> xValue

<oError> contains an error object with error information.

The method :onError() returns a value defined by the error handler.

The method :onError() is the standard handler for errors raised by the automation sub-system. If a COM operation raises an error, :onError() is called with an error object in parameter <oError>. The error object contains information about the error generated. Please be referred to the function Error() for further information on error objects.

:onError() evaluates the error code block set using ErrorBlock(). The default error handler installed by the runtime system displays a runtime error for errors raised by COM operations.
