Reset revision history

[arj]

How do i reset the revision history of all the VI's in a library without doing one at a time. THanks

In LV 7.0 use Invoke Node and the method Clear History. This method is missing in previous versions.

I tried it, but it doesn't reset the revision history. What's wrong with the attached code?

Hello Einstein,

I tried running your example and it cleared the revision history of all the VIs I tried. Is it possible that the file settings for the VI you are resetting is set to Read Only.

Regards,

Hello Matt F,

I tried that, but that's not it. When I set the read-only flag, I get
Error 8 occurred at Invoke Node in ClearVIHistory.vi
Possible reason(s):
LabVIEW: File permission error.

I also added the Access Rights VI and it indicates 110110110 when the VI is not read-only, but the history is still not reset. It's strange when you say it works for you...
I use LabVIEW 7.1 on Win XP Pro (I saved the VI that I posted earlier back to version 7.0). I have two partitions: one with NTFS and one with FAT32, but I don't see the expected result on neither of them. I do have administrative rights on this system.

I also tried other VIs, e.g. the 'Select Signal Dialog.vi' that ships with LabVIEW (...\LabVIEW 7.1\examples\general\templates\Dialog (Base Package)\...), but no success here either 😞

Any ideas?

Hi Einstein,

I downloaded and ran your VI (on another VI), and it seemed to clear the history just fine. I'm running WinXPSP2 & LabVIEW 7.1. Have you tried running this on another machine around you?
