I'm trying to use MicroSoft Access 2003 to control the digital lines of a USB-6501. Access uses VB for coding, but I don't know which version. I have been able to control a PCI-6503 with Access but have had no luck with the USB-6501. I've had trouble with NI-DAQmx and NI-DAQmx Base too. Rightnow it seems that I can not control the 6501 with Access. My skillset working with VB is limited. Any help (keep it simple) and examples would be a great help.
