Zero Width Column in ListView Control

Recommended Posts

I am using AutoIt to create a ListView control in a form. One of the columns in the control contains internal database ID's - something that the end user doesn't deal with and would know nothing about, but is very important to the logic in my program. Is it possible to set the width of a populated column in a ListView control to zero? This way I could access the value programmatically, but keep it hidden from users.

I think I could probably create a two-dimensional array of listview items, where one dimension stores the ListView item, and the other stores the internal db value. But I'd like to know if there's a simpler way to do it.

Thanks for your help!
