opening version warning

[lmtis]

Is there a way to make LV give an advance warning before opening a VI that is from a previous version?

Perhaps my search skills are lacking, but I cannot find a posting on this issue.

LabVIEW doesn't do that.

You can use an application invoke node (Get VI Version) to find out what
version a vi was made in, before opening it. But that's all.

You might wish to add your opinion and reasoning here.

Thanks tst.  I hadn't found that thread ... I need to improve my search skills   Unfortunately it won't help me with my LV5, 6.01, 7.1, and 8.0 work.

You can also submit a suggestion in the Product Suggestion Center.

You would think that this could be easily implemented, sort of a LabVIEW launcher.  We know that the system knows, because in the run time environment, it has to utilize the correct runtime version. 
This morning I have played around a bit, I can see where the version is identified, but it is not a fixed offset I also only have LabVIEW versions 8.2.1 and 8.5 on my system, and have not looked at older VIs, nor have I tried to identify which versions of LabVIEW are installed... which should be a trivial task.  I am trying to look for a common header to the version, and may be onto something... but I need to pull out the old disks and load up some older versions and take a peeksy, and see if they changed something. with lvlib, & proj, they are identified in XML so that would be a piece of cake. 

Anyways, I will poke around some more when I have some more time.

As I mentioned in the other thread, it would probably be easier just to write a tool which uses the method described earlier.

would need to check to see if it recognizes old old versions Like 3, 4, 5, and 6...
I can look into that in a bit.
