Hi...
Welcome, first of all...

1 - Use ListBox1.Items.SaveToFile('C:\test.txt');

2 - Use ListBox1.Items.Delete(ListBox1.ItemIndex);

Thanks!

Thank you very much!
Can i ask another question?

i don't know how to store one column of the listbox into a string
value ...
How can a string value read the items of the Listbox line by line?

OK...

One column or line?

MyString := ListBox.Items[1];
This get the second item from list (the first is 0) and store them in
string MyString...

in loop...
for i := 0 to listbox1.Items.Count - 1 //start in 0, don't forget
MyString := ListBox1.Items;

Thanks!
