Compare two VI's in Labview 8.2.1 Full Development System

[arnold_w]

I am using Labview 8.2.1 Full Development System. I want to compare two VI's, what is the best way to do it? I am not using any source code control software. I am thankful for any advice.

hi

LabView has an own function to compare to vi´s.

Please let me know step-by-step how to use it.

Hi

tools -> compare -> compare V´s. than select the two vi´s two compare (they must have different names) and than labview list all differences between them.

Compare does not exist under the Tools menu in my LabVIEW, I looked both on the Front Panel and on the Block Diagram. What could be wrong?

[MikeS81]

oh sorry

i can´t say where it is, because i have LabView 8.5 with german language. But i know this feature already exists in LabView 7.1. In my version it is under tools.

I just found out the compare feature is only available in LabVIEW Professional. Does anybody know if there are any third party tools available to compare VI's?

So I've checked the other computer in my cubicle, the one that still has 8.2.1 on it and I did find the compare VIs function you are looking for.  It is actually under Tools --> Compare --> Compare VIs.  However, the Compare section under tools only shows up when I have a project or VI open and the Compare VIs function is only enabled when I have an actual VI open.  This also works if you open 8.2.1 and select "Blank VI" you will be able to get to this menu.  It then pops up a dialog with 2 select buttons to choose the VIs you want to compare.  It defaults the first VI to the one you selected compare from, but you can change it to whatever you want.

Hope this helps.

Thanks for your advice, but please see my previous post.

They need to add functionality to the board to "update thread" right before you hit submit so you don't give advice right after it becomes "silly" to give the advice

I have seen something called LVDiff from Meta Diff http://meta-diff.sourceforge.net/.  This helps with comparing of VIs when using the PushOK CVS SCC implementation of source control.  But it does appear to only work with the compare function already in the professional version.  So that probably wouldn't help you out.

Other than that I haven't seen any third-party software, but I'm sure it does exist.

Sorry I wasn't more help.
