Question

Hello,

My question: is there a way to transform each element of a muticolumn listbox to a pull-down menu ?
if not, how could i assign the data selected from a menu to an element in the multicolumn listbox ?
Thx,
Samer,

You have 2 problems:
The combobox's Z-order is that it's in the back. You need to move it to the front. Select the table, and select the "Move To Back" command from the Z-order button in the toolbar.
The "Tableau" array is initially empty. When you perform a Replace Array Subset you're trying to replace an element in an empty array. Result: empty array.
Other issues:
You need an event case for the "Stop" button. The way it's coded now, clicking the "Stop" button will not stop the VI until another event occurs, which in your case is that someone clicks in the second column.,
You have a few extra unnecessary property nodes. See attached picture.
You can use the error cluster to enforce data dependency, and therefore execution order, eliminating the need for the sequence structure, which is extraneous. See second attached picture.
"<Empty>" is not one of the valid strings in the combobox, so this test will never work.
