You'd write something like this
text1.text = ListBox1.Items.Item(2).ToString()
The array holding the items is zero based, which means the 3rd item is really the 2nd element in the array.
Thanks for reply :) just want make something clear, does the order of the item count from the top?? if yes, so the top one is 0, second one is 1, third is 2, fifth is 4?

that's correct. It's zero based indexing starting at the top. The last item will always be
listbox1.items.count - 1. Remember the minus 1 when working with listboxes. You can also check if a listbox has any item selected through:if listbox1.selectedindex = -1 then 'none is selected end ifPosted by The ANZAC : "WWBD, What Would Buffy Do?" : "I don't know man, she's stronger than me"

NO DON'T USE THAT PLEASE! That is a bad habit, to form a dependency on old vb6 methods, you should learn the new way because those methods will be phased out, most likely in the next edition. Do this:
me.listbox1.selectedindex = 'whatever number between 0 and listbox1.count - 1 or a variablePosted by The ANZAC : "WWBD, What Would Buffy Do?" : "I don't know man, she's stronger than me"
