Hi TiTou,

I hope you don't mind me taking this thread allitle off track but I'd like to scream over a change between LV 8 and 8.20.

I support many applications in many versions. As a result I have to make sure I don't accidently upgrade older applications by saving them in a higher version.

This requires I make a formal decision which version of LV to open before I switch to a new applicaiton.

Well I just saw (and repeated ) something that is going to be quite anoying.

IN the OLD DAYS (pre LV 8.20) LV would write something somewhere that told Windows which app was associated with .VI files. So provided I opened and closed a VI in the proper version, from that point forward, Windows would open the version of LV I last had open.

Well it appears that once LV 8.20 is opened and closed, the double-click in the Explorer window always opens LV 8.20 even if I just closed LV 8.0.

AAAAARRRRGGGGGHHHHHH!

I don't think it ever mattered which version you closed last, just the version you opened last. 😉

Actually, a double click opens the VI in the last version you OPENED, not the last version you had open. This is an important distinction and I don't think that this has changed. I only installed 8.2 eval a few days ago, and I can't check it at the moment, but my impression is that this hasn't changed. Try opening 8.0 again and then double clicking the VI.

If that doesn't help, try right clicking any VI in Explorer and see if you have the option of opening it with "LabVIEW Development Environment" (no version number). It's possible that this tells it to always use the last version opened or that that is simply how 7.0 and below appeared in the program listing.

In any case, if memory serves, there was an INI setting for controlling this (try Brian Renken's site).

And one last thing, you can always try the version chooser from Dataact.

Well I am not completely crazy.

After a re-boot of my machine I did the following:

1) Open LV 8.0

2) Close LV 8.0

3) Double click on VI from explorer  ---->  VI Opened in LV 8.20

4) Closed without saving and shutdown LV 8.20

5) Open LV 8.0

6) Double-click VI and it opened in LV 8.0

7) Saved the VI

😎 Closed LV 8.0

9) Double-click VI in  Explorer and VI opened in LV 8.20

I did that and LV 8.0 is not in the list (see image)!

If someone else get the oppertunity to test this, please let me know what you find.

If confirmed I will have to report this as a bug to make sure this behaviour does not propogate to future LV versions.

Ben,

I just finished editing a VI im 8.20. Now I did the following:

1. close VI and close 8.20.
2. open LabVIEW 8.0.1
3. close LabVIEW 8.0.1
4. double-click a VI in explorer.
5. --> VI opens in LabVIEW 8.0.1 as expected.

I cannot reproduce your observation at all. Did you install everything in the default locations? Did you possibly install over a beta version?

Thanks Christian!

Thanks for trying.

One possible difference is I am using LV 8.0.0.

BETA is not a possible explanation.

I reported this to support ( service request # 863207) and the AE was not able to reproduce my observations.

If no one else sees this issue then I will write this off to my machine.

you're not going crazy, Ben..

well... not yet 😉

Hi Ben,

How come you have the possibility to choose the LV version to open your VI when right clicking ? (picutre you posted)

I really wish I had that... when right clicking on a VI I can only choose between LV 7.1.1 and ... "firefox" to open it
I have LV8.0.1 and LV 8.20 installed.
On top of that, if I :
  1. right click a VI,
  2. go to open with...
  3. select "browse" and point to labview.exe in the LabVIEW 8.20 folder
  4. -> vi opens in LV 7.1.1

Anybody has the same problem ?

[TiTou]

So,

Here I come again with my "grumpy attitude"

It seems to me that NI hired a bunch developpers coming straight from Microsoft !

To helps us developping a large app, LV 8 introduced the project managment - great idea !
So let's go working on a big app, and try to close a VI without saving changes... I can choose between "save", "defer decision" and "cancel close".
What the hell is that "defer decision" ?
When I close a VI there are 3 possibilities :
 1. I did it accidently and then I will want to "cancel close"
 2. I meant to close it and want to save changes,
 3. I meant to close it but I don't want to save changes, but to do this I have to cancel, revert and close again... INSANE !

but I swear to god that never in my life I will want to defer my decision, specially if I work on a big app, because at the end LV gives me a list of all VIs and asks my wich vi has to be saved or not, will I remember ? Certainly not !


I really wonder if any of you ever clicked on "defer decision" and if yes, WHY ??
