Hi Together, I know this is a rather old thread but maybe there is still someone interested ... It seems that queue references become invalid after the VI having created them returns to the idle state. I tried to use dqXclass objects in conjunction with dynamically called VIs and nearly got mad during debugging... Always after a first VI succesfully created and used the objetcs the second VI failed due to invalid references. Does anybody have a good solution for me? Do I have to create "creator VI" running permanently in the background, keeping alive the queues? Best regards Arno
