Hi Rolfk, You are absolutely right! I missed that last bit in the original posting. Only versions of LabVIEW 7.0 and later will have support for the DAQmx driver.
In Traditional DAQ, you can read the virtual channel properties, but you cannot programmatically change them. The best workaround to this would then be to switch between different MAX config files, as was mentioned in the beginning. Sorry about the confusion there. Upgrading to LabVIEW 7 is definitely the recommended step since the DAQmx driver provides several nice enhancements including a multithreaded driver and the integration of a DAQ Assistant Express VI in LabVIEW.
