ListBox Row Choose Problem

[ahmelsayed]

Hello Eveyone,

I've a list box that contains some options to be chosen whin clicked and stored in an array. Till now it is a simple task to be finished.

I need any of these options to be choosed only one time and to be stored only for one time.

My problem is that when i choose any of these items more that one time, It is directly stored in the array the same numbers it is clicked.

Can anyone help me with that issue ?

Thanks in advance.

How you are updating the value from the list box to the array?. May be you need to check the array for the element which is already present or not. This should be simple. please post the code or a snippet for solution (Please post VI in 2011 version)
