Disable windows task scheduler

[jz_007]

Hiya

Is it possible to disable the Windows task scheduler using Labview (v6). I'm running a DAQ program and I don't want it to be slowed down by Windows Critical Update etc. However I would like to re-enable the scheduler as the VI finishes, because it runs the backup.

Many Thanks

I do not believe that you will find a way to shut down the Windows scheduler. It is central to the OS itself. You might want to investigate ways to optimize your DAQ routine. Look into DAQ occurrences, and find creative ways to pace your loops. Use enough of a buffer so that a momentary lag won't kill your process. If that doesn't help, it may be time for LabVIEW RT.

I don't know how to do it, but I'd guess it's possible.
This link has some tantalizing hints. Search for Task Scheduling.

This link has more code, but it's not very easy to follow.

Good luck!

A workaround may be to increase the priority of LabVIEW in Windows. Here is an example program that does this:

Very belated thank you for your replies - priorities changed and this project got put on hold - I don't like forgetting to say thanks but it slipped my mind this time.

Have I managed it then? Well no, but it is obviously possible because some installers do it (including Windows Update, I think). If I ever pick up the project again, I'll let you know how I get on.

Cheers
