List boxes

Question:
How can I put the output of a do-while loop in a list box then delete it for the next run? ex. o=0 do (o=o+1) Randomize timer x=rnd( * 6)+1 z=x*4 Print z to loop

Answer:
The ListBox control has two methods available that are relevant to your question:

  • AddItem will add a new row to the ListBox.
  • Clear will empty the rows from the ListBox.
Instead of printing the output, you simply use this statement:
ListBox.AddItem z
To clear the box, call ListBox.Clear. That's all there is to it!
