Setting the Active VI

[B.Settles]

I've created a tool for editing a VI's description. The tool presents a list of VIs in a directory. After double-clicking on a VI the VI's front panel is opened, the connector pane image is displayed (thank you scripting), and the current description is shown. Currently I have this saved in my project folder so it shows up in my Tools menu. My problem is that when I run the tool via the tools menu, I can't click on the VI I'm editing to set it as the Active VI and I can't see how to do this with property or invoke nodes. When I run my tool as a regular VI (not via the Tools menu), I don't have this problem. Any ideas???

No I cannot post my VI (internal network not connected to the internet).

i had the exact same problem a while ago, there is a thread on LAVA, i'll try to find it again.

basically, when your VI is launched from the tools menu, it runs in a different "context" (=application instance) from the one your project VIs are in.

so your "utility VI", when launched from the tools menu has to get the application reference of your project.

see this :

Hope this helps

EDIT :

here is the thread i was talking about : http://lavag.org/topic/9273-accessing-vis-across-contexts/

There's also a great full example of integrating a scripting VI into the Tools menu in the docs section.
