Hello,
I don't quite have enough information to answer this question. Are you using LabVIEW? Which version? Are you just trying to increment the value of the slide bar every second?
If that's your application, then it should be pretty easy to do in LabVIEW. Just place a Wait Until Next Millisecond Multiple VI in a while loop, with a 1000 wired into the time input. Then just use the iterator (the i) and wire it into a local variable for the slide bar that has been changed to write. Wiring into "Value" for the slide bar property node will also do it. If you'd like I can send you a little example if you tell me which version you're using.
Hope this helps!
