Hi Rong,
The Compatibility VIs were written for LabVIEW 7.x and the Traditional DAQ driver version 7.2. The VIs themselves shouldn't have any problem opening in the later versions of LabVIEW, but I have never actually tried these VIs personally, nor know how they will operate with other versions of the driver. I would caution you against it because the VIs actually replace part of the Traditional DAQ library in order to decide weather a device should be accessed with the actual Traditional DAQ driver, or if the shell VIs around DAQmx should be used.
And also, keep in mind that Traditional DAQ is a legacy driver at this point. We will no longer develop it, and so it would be benificial for your future re-use of this code to go ahead and convert the Traditional DAQ VIs into DAQmx VIs. In the long run, this will probably be the best solution.
