I want all the data that is in a listbox on form1 copied to a listbox on
form2. How can i do that?

Greets,

form1.listbox1.items.AddStrings(form2.listbox2.Items);

Form2.ListBox2.Items.Assign(Form1.ListBox1.Items);

AddStrings appends the strings to those existing (if any), Assign replaces
them.

One way is with a single command line using the Assign method of string
list objects (of which the TListBox.Items property is one).

  ListBox2.Items.Assign(ListBox1.Items);

This copies the items from ListBox1 to ListBox2, but entirely replaces what
was in ListBox2 before that.

To make the copying cumulative, base a loop on the TListBox.Items.Count
property and in that loop traverse each item in the source TListBox. At
each item, call the TListBox.Items.Add method to add it to the destination
list box. Something like:

  for i := 0 to (ListBox1.Items.Count - 1) do
    ListBox2.Items.Add(ListBox1.Items[i]);
