node property global variable

[samerham1]

Hi,

How could i access to the property nodes of a global variable ?
Thx,

You would need to open a reference to the VI and then access the front panel and then the controls on the front panel. For example, this will return the labels of all the controls on a global variable:

Hi samer,

even with smercurios excellent answer:
Why do you need to access property nodes of global variables??? What do you want to achieve?

I am curious as well. We may be able to offer alternatives.

Sometimes I just throw my hands in the air and don't bother asking this and just decide to answer the question as stated, since I know the poster will likely follow up with the real question, or additional information that completely changes the premise of the question.

I suspected it had something to with this.

Hi GerdW & ben...Thank you for your concern...

smercurio_fc is right... i was asking the question in relation with this subject: http://forums.ni.com/ni/board/message?board.id=170&message.id=339923#M339923

In the subVIs and the VI i need to access to the property nodes of the global variable...

What do you think ?

Hi samer,

you still don't say why you need to access properties of global variables...
Globals should only be used as data storage/provider. You don't show the fornt panel of a global vi to the user, so properties are irrelevant...

Uhm why not, I have done it  in the past as an advanced debug function.

Hi Ton,

that's an interesting point! (Always trying to improve my LV knowledge)

Did you use properties to show different states of the running vi?

[samerham1]

Hi,

sorry for answering late...

The reason of needing the global variable node property is that i have a listbox variable in my global variable vi ...and I need to access to the properties of the listbox in my vi and subvi.

in my subvi I need to read to the contents of  this listbox...and in my vi i need to wrtite into the listbox...so i need the properties to do so....

Is smercurio solution is what i need ?

if not could you help me ?
