You have posted this message to the LabWindows post area, which is under the Measurement Studio family. This includes CVI, NI's own programming environment based in ANSI C, as well as add in components for Visual Basic and Visual C++. This prgram would be capable of controlling your system from the software side, but your program would be text-based. You mention in your title that you want to use LabVIEW, which is a separate graphical environment, but I didn't know which one you were really looking into. Please post back, and I can move this along to the correct group, so we can find an answer for you. Thanks.
