re-initalize Listbox to default values

[nyc_(is_out_of_here)]

Using LabVIEW 2010.

It seems that an Invoke Node to Reinitialize to Default for a Listbox does not work. I have to wire an empty array to the Listbox's Item Names Property Node.

Am I doing something wrong?

mmm, I tried it myself, and it doesn't work either.

In the other hand I used to initialise them by wiring a constand empty string.

Reinitialize To Default (whether done programatically or from the front panel, only affects the Value of a control, not any of the other properties (such as the items in the list).

[nyc_(is_out_of_here)]

The "value" of a Listbox appears to be the selected items index and not the items in the Listbox.

Just seems odd there is no quick way to clear out a listbox short of wiring an empty array.

Hello,

I am learning labview, How do you wire a constant array string constant to the listbox?

Thank you

You create a property node for the listbox and choose 'ItemNames' for the property node.

Thank you very much it worked, However, i have another question if you don't mind.

i have a list of 3 columns and n rows ( # of players that show up). The columns consists of : #players.....players names ....and... paid dues  .My problem is the paid dues...I cannot figure an array of players that haven't paid yet. I can total the dues that were paid  but not the names of the players that haven't paid. I hope it's clear enough.

I want to have an output of the players that haven't paid yet programatically. I can total the dues that were paid  but not the names of the players that haven't paid. I hope it's clear enough.

Anybody.....

Iterate over the 2D array of strings and use a conditional tunnel that auto-indexes the second value (player name) for all row where the third array value is an empty string.

Modify according to the exact requirements.
